Title: Improvements in or relating to heating or drying apparatus employing a gaseous heating medium
IPC: F26B17/20
Filed: 1923-07-17
Abstract: 223,298. Sterling, Sir J. W. July 17, 1923. Screw conveyers; air and gases, controlling direction of flow of.-In heating or drying apparatus of the type in which the material to be treated, e.g. wet organic or mineral matter, is propelied by a screw through a conduit into which a gaseous heating or drying medium is admitted, the hot air or super-heatsd steam employed is injected under pressure through the conveyer conduit wall 5, Fig. 1, into direct contact with the material under treatment, and means such as non-return valves, are provided at the inlet 24 and outlet 14<1> for the material to prevent leakage of the gaseous medium at these points. The steam or hot air is led through a pipe 17 extending parallel to the conduit 5 and discharged through separate valve controlled branch pipes 18, Fig. 3, from which the steam or hot air issues in two diverging jets 21, 22, the former imping- ing directly upon the area where the material 20 tends to accumulate. The steam or hot air is discharged from the conduit through an outlet 23 at the same end as the inlet 24 for the material, so that to a limited extent the process is carried out on the counter-current principle. Leakage of the gaseous medium at the inlet 24 is prevented either by the bulk of the material itself or by a hinged flap-valve, while a rotary discharge valve 14 for the material located in the outlet 14<1> and geared to the shaft 9 prevents leakage of the gaseous medium at the outlet 14<1>. The blades 13 tor propelling the material through the conduit are formed with stems adapted to engage apertures in the shaft 9 and to be secured by nuts so that, by turning the stem, the rake or pitch of the blade may be varied, while one or more of the blades as shown at 25 may be reversed so as to increase the time during which the material is subjected to the heating medium. In order to facilitate access to the shaft and blades, the conduit is split longitudinally at 26, both the upper and lower halves being built up of detachable sections.

Title: Improvements in and relating to fuse-switches
IPC: H01H9/10
Filed: 1939-06-24
Abstract: 530,854. Snap-action switches. DORMAN & SMITH, Ltd., and SMALLEY, T. June 24, 1939, No. 18444. [Class 38 (v)] An enclosed fuse-switch is locked in both the closed and open positions by a spring-pressed bolt 20 on a movable part 15 of the mechanism engaging one of two holes in the side of the box ; this bolt is withdrawn by the normal movement of the operating lever but the withdrawing movement is prevented when the box cover is removed; interlocking mechanism 17, 18 also prevents the cover being removed when the switch is closed. The movable contacts of the switch (not shown) are carried by a frame 13 which is given a parallel movement by links 15 pivoted to the frame at 14 and to fixed points 7. The upper link 15, which is a U-shaped member carries the bolt 20 and has the extension 17 which overlaps the hook 18 on the cover 19 to prevent removal of the latter when the switch is closed. The operating lever, which is outside the switch-box, rotates about the upper axis 7 and drives a member 8 pivoted to a rod 22, 23 which passes through a block 24 and is surrounded by a compression spring 26. The block 24 is pivoted to an extension of link 15 and when the member 8 is rotated by the handle, the rod 22, 23 tilts, the spring 26 becomes compressed and tends to rotate the link 15. Movement is however prevented by the bolt 20 till a bevelled edge 9 on the member 8 presses back a cone-shaped portion of the bolt 20. When the lid is removed, a plate 28 which normally rests at 30 against the hook 18 moves to the right under the action of a spring 29 so as to come behind a portion of the bolt 20 and prevents its withdrawal.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M5/04
Filed: 1929-06-15
Abstract: 331,366. Blackburn Aeroplane & Motor Co., Ltd., and Blackburn, H. June 15, 1929. Spray carburettors. - Fuel is raised from a constant-level chamber B, Fig. 3 to a suction nozzle D by a wheel having transverse fuel ducts C equally spaced around its periphery. The fuelraising wheel is driven through gearing by a vane wheel C6 located in the air intake. The fuel ducts may be formed by short lengths of tube fitted to a skeleton disc C1, the opposite'ends of each duct being cut obliquely and parallel to assist the flow of fuel therethrough as the wheel is rotated. The suction nozzle D is inclined upward towards a point in the pitch-circle of the ducts and is so arranged that under the combined influence of gravity and suction the fuel follows an easy path from the ducts to the nozzle, the bore of which is made larger than the intake orifice. In a modified construction, Fig. 5, the fuel ducts are formed by radial slots, the outer ends of which are closed by a thin ring E3 fitted over the wheel periphery. Alternatively, the ducts may be formed by transverse bores in the rim of the wheel. The oblique ends of the fuel ducts are formed by milling the side faces of the wheel disc as shown at E4, E5, Fig. 5. The axes of the fuel ducts may be inclined relatively to the axis of rotation of the wheel, in which case the ends C7, C8 of the tubes, Fig. 3, would not be cut obliquely and the suction nozzle may be arranged horizontally as shown in Fig. 5. The constant-level device comprises a needle valve located in a fuel supply pipe B8 and an arm which is caused to actuate the valve by movement of the chamber B containing the fuel, into which the lower portion of the fuel-raising wheel dips. The chamber B is pivotally mounted and is balanced by a weight, the position of which may be adjusted according to the level required and the specific gravity of the fuel. The exit B10 of the fuel supply pipe may be directed towards the intake ends of the ducts in the fuelraising wheel or, according to the Provisional Specification, fixed baffles may be provided' in the chamber to direct the flow from the supply pipe towards the ducts.

Title: Improvements in pencils with slidable lead
IPC: B43K21/06
Filed: 1931-06-29
Abstract: 369,822. Pencil holders. BL€SING, H., 46, Kaiserstrasse, Saarbr³cken, Germany. June 29, 1931, No. 18763. [Class 146 (iii).] A propelling pencil comprises two half-shells grooved for the reception of a lead, means for clamping the shells together, a slider wholly or partly surrounding one or both of the shells and having a member projecting inwardly between them to abut the end of the lead for propelling it, and ratchet or like locking means for preventing backward motion of the slider. The slider d may embrace one half-shell and engage the lead k by means of a projecting portion d<1> provided on one of the ends. Both the inwardly turned ends have turned-up portions forming resilient tongues which engage a series of teeth e provided on one half-shell. The half-shells are held together by clamping- rings c at each end. In a modification the rear end of the pencil is provided with a cap instead of a clamping-ring and the teeth do not extend to the outer surface of the shell. In another form the slider consists of a split sleeve resiliently embracing both half-shells, a tongue being cut out of the sleeve wall and projecting inwardly across the groove for the lead. The tongue carries a wire loop the ends of which are bent outwardly to press against the walls of the grooves so that they yield and slide when the lead is advanced, but directly engage the sides of the groove when pressure is exerted on the lead so as to prevent backward movement. Instead of the wire-loop locking-arrangement, the split sleeve may be provided with resilient tongues pressed inwardly from its wall and rearwardly directed so that when pressure is applied to the lead the tongues engage the half-shells.

Title: Improvements in electric timing relays
Inventor: SHARP ALEXANDER
IPC: H01H7/10
Filed: 1955-06-29
Abstract: 833,482. Electromagnetic switches; control Of motors. M & C SWITCHGEAR Ltd. June 14, 1956 [June 29, 1955], No. 18789/55. Classes 38 (3) and 38 (5). A switch intended to control two contact sets in timed sequence comprises a contactoperating lever 17 pivoted at 21 and operated by an armature 41 through a push-rod 25 against the retarding action of the extendible rod 12 of a timing device 11 of known construction. The lever 17 is in three parts 30, 31, 32, the parts 31, 32, being clamped together by a spring device 36 and the part 31 being mounted on the fulcrum 21 and biased by a tight spring 33 so that the part 31 abuts a stop-screw 34 on the part 30. The part 32 insulatedly carries a bridging contact 19 cooperating with a pair of contacts 20 on an insulating base 16 whilst the part 31 carries a striker 22 co-operating with a normallyclosed spring-biased bridging contact 23 engaging fixed contacts 24. When the coil 40 is energized the armature arm 43 is raised to compress a spring 26 arranged between an abutment 46 on the rod 25 and a collar 45 slidable on the rod and the lever 17 is tilted against the delay action of the device 11 to close contacts 19, 20. As the armature continues its delayed movement the part 30 moves independently of the parts 31, 32 which remain stationary, the spring 33 holding the contacts 19, 20 closed against vibration. Eventually the retarding action of the device 11 ceases and the rod 25 moves rapidly upward and a tongue 35 on the part 30 " breaks " the part 31 from the part 32 so that the striker 22 opens the contacts 23, 24. On de-energization of the coil 40 the switch parts return to their initial condition without any delay action of the device 11. The time at which the contact 19 closes may be varied by adjustment of the stop-screw 34 whilst the further time taken for opertion of the striker 22 may be varied by adjustment of the threaded upper end of the rod 12 in a bore in the pivot 18. Fig. 5 shows the application of the switch to a system in which a motor 51 controlled by a starter 56 drives an endless conveyer belt through a traction-type hydraulic coupling, the conveyer having a spring brake preventing its movement until there is sufficient driving torque, the brake being released by a motor 52 having a starter 59. The circuit 53 is connected to the switch coil 40 and the solenoid 58 of the starter 59, whilst circuit 54 includes a starting relay coil 50R operating a contact 50 and the switch 23, 24 connected in parallel with a switch 60 which is closed when the brake is released. Closure of the start button 62 energizes coil 50R to close contact 50 and energize solenoid 57 of starter 56, thus starting the motor 51. Also, coil 40 is energized and after a time interval contact 19 closes to energize solenoid 58 and start motor 52. Eventually contact 23 opens but the circuit 54 is maintained through the previously closed switch 60. Thus should the brake fail to release the circuit 54 is opened by the contact 23 to open the starter 56.

The upper surface of the member 7 may be ornamented, e.g. to represent a piano keyboard.
Patent GB-375557-A (GB)
Title: Improvements relating to indexing or dividing mechanism for machine tools
IPC: B23F23/08
Filed: 1931-07-01
Abstract: 375,557. Indexing. GEAR GRINDING CO., Ltd. and BULLOWS R. J., Anne Road, Handsworth, Birmingham. July 1, 1931, No. 18973. [Class 83 (iii).] In an indexing-mechanism for machine tools, particularly machines for grinding spline shafts or toothed gears the work spindle a carries a notched or toothed member b and is acted upon by a constantly-acting uni-directional torque which is effective to cause the indexing movement when a pivoted pawl c is moved out of engagement with the notched wheel b. The pawl is held up by a spring plunger coacting with an abutment e and the continuous torque is applied by a multicylinder fluid motor f actuating a crank g on a spindle h which is connected to the work spindle by gears i, k. The spindle h is formed as a valve to control the fluid supply to the cylinders and fluid from a pump passes to this valve through a pipe and valve v. The pawl is released for the indexing movement by means of a rod q acting through lever mechanism, Fig. 2, the rod being moved by a lever u controlled by a hand-lever x, and being quickly returned by a spring r so that the pawl engages the next succeeding notch on the wheel b. The lever x may also be actuated automatically through the engagement of a stop 9 with an abutment 8 which is mounted on a slotted bar 6 connected to the lever x. The supply of fluid to the motor is regulated by the valve v which, when the parts are in the position shown in Fig. 2, restricts the flow to the motor. When the rod q is raised to disengage the pawl, the valve v opens to permit a larger flow of fluid to the motor and on the return of the rod q the flow is again reduced to prevent shock when the pawl engages the next notch. In a modification, an electric motor may be employed for moving the notched wheel, in which case the rod q controls a switch.

Title: Improvements in and relating to watering systems for agricultural, horticultural and such like purposes
IPC: A01G25/16
Filed: 1946-06-25
Abstract: 623,810. Fluid-pressure servomotor-control systems ; garden sprayers. NEWTON, R. W. June 25, 1946, No. 19001. Convention date, June 28, 1945. [Classes 69 (iii) and 135] In a watering system, e.g. for horticultural purposes, a series of water delivery units connected to sprayers are arranged to discharge intermittently and according to a predetermined sequence. A watering system, comprising four delivery units A, B, C, D, Fig. 1, connected in parallel to a main inlet pipe 3 is controlled by a spring-loaded valve 14 which may be operated either manually or automatically by a time device or a device responsive to the temperature or humidity of the soil. Opening of the valve 14, Fig. 2, releases the hydraulic lock on a diaphragm 9, which lifts under the mains pressure to supply water to the delivery units, and which by means of a pivoted striker 19 and a cam 21 temporarily opens a spring- loaded valve 22 to permit a diaphragm valve to pass a limited quantity of water through a branch pipe 7a to a tipping basin 59, Fig. 3, carried on one end of arms 66, which are pivoted on the casing of the delivery unit A. When the basin tips, an adjustable striker pin 69, screwed into a balance weight 68 on the other end of the arms, opens a valve 36 to release the hydraulic lock on a diaphragm valve 32, and water flows to the outlet 28 of unit A. A check valve 44 in the outlet ensures that sufficient pressure is maintained to force water through a pipe 47 to a chamber 54 of the unit B, where it acts on a diaphragm 52 connected by a rod 57 to a hemispherical member 64, which is lifted to close the outlet from the basin and to hold the basin in its normal position. This basin is gradually filled by the passage of water from the chamber 54 through a groove in the rod 57. When, owing to escape of water through ports 62, the basin of the unit A returns to its normal position, valve 36 closes, and leakage of water through a bleed port in the diaphragm valve 32 locks it closed, thus cutting off the supply to the outlet of unit A and the chamber 54 of unit B. Water is then discharged through unit B since the drop in pressure in the chamber 54 releases the tipping basin. Intermittent discharge from consecutive delivery units continues until the valve 14 is closed.

A test set for radio navigational equipment comprises means for generating pulses simulating the signals transmitted by a beacon such as TACAN and for amplitude modulating the pulses to simulate the effect of a rotating antenna pattern. The following test facilities are provided. (1) Identity tone signals consisting of 1350 pairs of pulses per second the pulses of a pair being spaced by 100 Á.sec. (2) Main reference signals consisting of 12 pulses spaced by 30 Á.sec. and having a repetition frequency of 15 c.p.s. (3) Auxiliary reference signals consisting of 6 pulses spaced by 24 Á.sec. and having a repetition frequency of 135 c.p.s. (4) Reply signals consisting of suitably delayed interrogation pulses to simulate the distance between the test set and the (mobile) equipment which transmits the interrogation pulses. All of the above pulse signals are combined into a single pulse train and for each pulse of the latter a second pulse is generated spaced therefrom by 12 Á.sec. to enable single random-wise pulses to be differentiated therefrom. The composite train of pairs of pulses is then amplitude modulated by a complex wave having a fundamental frequency of 15 c.p.s. and a harmonic of 135 c.p.s. and transmitted on a U.H.F. carrier wave from an aerial having a fixed radiation pattern.
