Filed: 1926-02-13
Abstract: 248,353. Maurer, A. Feb. 24, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Disc and wheel apparatus; trueing rotating tools; spindles and spindle mountings.-A grinding-wheel is trimmed by a carborundum or other hard wheel 14 mounted at the overhanging end of a spindle 6 by means of a nut 16 and a washer 15 on the spindle, which is mounted in ball bearings 4, 5 in a casing 1. The bearing 4 is larger than the bearing 5 and is mounted obliquely-as shown to take up side thrust and the inner rings of the bearings are spaced by a sleeve 7; the outer ring of the bearing 5 is not anchored, and a spring 13 takes up wear in the bearings. A groove in a ring 10, which holds the outer ring of the bearing 4 in position, co-operates with a rib 11 on a disc 12 on the spindle 6 to exclude dust from the bearings. In use, the device is mounted by an extension of the casing so that the axis of the wheel 14 makes an angle of 10‹ to 30‹ with that of the grinding-wheel undergoing trimming, and the wheel 14 is driven by its frictional contact with the grinding-wheel.

IPC: B23B5/06
Filed: 1920-02-11
Abstract: 151,527. Wilson, F. W., and Richards & Go., G. Feb. 11, 1920. Turning crank-pins and shafts.-In a crankpin lathe of the rotating-carrier type the cutting- tool are supported in slides k so arranged that the tools are centrally disposed with respect to the V-shaped bearing-surfaces of the carrier on the housing h. A single tool the whole width of the crank-pin may be used, with or without tools for finishing the webs, to facilitate which operation cross slides may be made use of. Clamps e hold the webs on each side of the, pin, the shaft being held in V blocks b for readily centring the pin. Rotary tool heads.-Each of the tools is fed by a screw n placed centrally behind and in line with the cutting-edge. The feed is obtained by worm wheels o driven by worms p and pinions r gearing with inside teeth on a ring s which is rotated by means of outside teeth and a pinion t, driven by a toothed wheel v and the change-speed gearing..shown in detail in Fig. 4. The toothed wheel v is,'by means of a key 2 and handle 4, clutched tn one or other of the wheels x, y, z, gearing respectively with wheels 5, 6, 7 on a loose sleeve 8 connected to a power driven shaft 12 by a spring stud 9 and a groove 10 in a sleeve 11 which can slide on the shaft 12. The wheel y gives a speed to the ring s equal to that of the carrier j. A hand feed is obtained in addition by means of a disk 16 rotated as desired by a hand wheel (not shown) so as to oscillate a lever 14 and thereby the sleeve 11, imparting additional rotation to the sleeve 8. A differential gearing of the ordinary kind may replace the hand-and power gearing described, to obtain the same result.

Patent GB-658870-A (GB)
Title: Improvements in or relating to tamper-proof overseals for containers
IPC: B65D43/02
Filed: 1949-12-08
Abstract: 658,870. Capsule-sealing devices. METAL BOX CO., Ltd., BENNETT, H. J., and KITCHEN, F. G. Feb. 16, 1949, No. 4293. [Classes 66 and 125(iii)] A tamper proof overseal, which cannot be removed from a container without visible mutilation, consists of a capsule having a crown part from which depends a skirt having an outwardly flared lower portion terminating in an inturned annular flange made shorter than the flared portion. The container is provided with an outwardly projecting rim, the diameter and length of the skirt being such that when the capsule is placed in position on the container, the junction between the skirt and flared portion engages on the outer face of the rim so preventing rotation of the capsule, and the flared portion and flange can be turned about the junction so that the edge of the flange engages the underside of the rim. In the form shown in Fig. 1, the capsule, which is made of thin sheet aluminium or tin plate has a skirt 2 formed with an outwardly flared portion 3 which terminates in an inturned flange 4, which is of less length than that of the portion 3. Fig. 2 shows the capsule being applied to a metal container comprising a body 5, to the mouth of which is secured a neck ring 6 by means of a flat double seam 7. The container is closed by a cap 8. The capsule is applied by a downward stroke of a ring die 12, thus causing the flare 3 to be moved inwards and the flange 4 to become locked beneath seam 7, as in Fig. 3, the junction 10 between the annular portion 2 and the flare 3 being pressed tightly against the seam so that the capsule cannot be rotated and cannot be removed without distortion. To facilitate its removal, the capsule crown is provided with a tear-off strip, Figs. 7 to 9 (not shown).

Title: Improvements in or relating to valve devices for automatically regulating liquid pressure
IPC: G05D16/10
Filed: 1963-02-01
Abstract: 1,031,683. Fluid pressure servomotor control system. E. MURAKAMI. Feb. 1,1963 [Feb. 3, 1962], No. 4324/63. Heading G3P. A fluid flow control valve comprises a main valve member actuated in response to the inlet or outlet pressure. A main valve closure 3, cooperates with a seat 2 and the inlet pressure is fed through a passage 1A and a part 7a to the top of a piston 9. The inlet pressure is also supplied through a pipe 27a to act continuously on a small diameter piston 19a connected to one end of a rack 20 of which the other end is connected to a larger diameter piston 19. Movement of the rack rotates a pinion 22 which rotates a valve member 11 to lift the valve or lever the valve into its seating 10a formed on the piston 9. The valve 11 controls leakage of inlet pressure from above the piston to the outlet to control the opening of the main valve 2, 3. Fluid pressure supplied and exhausted from the space 14 housing the larger piston 19 is controlled in response to inlet and outlet pressure. When the valve 3 acts as a pressure relief valve, the inlet pressure in passage 7 is fed through a passage 27, fig. 2 (not shown) to a Bourdon tube 34. A rise in the inlet pressure above a predetermined valve,determined by the position of a rod 38 causes a lever 36, pivoted to the rod 38, to rotate and act through a rod 40 to close a valve 29a and open a valve 30a whereby inlet pressure in the passage 27 is fed past the open valve 30a to a passage 28 which leads to the chamber 14 and thus causes the rack to move to the right and hence valve 3 to open. When the inlet pressure again falls, the valve 30a closes and the valve 29a opens connecting passage 28 to a passage 32 which leads to the main valve outlet and the rack moves to the left under the action of inlet pressure on the smaller piston 19a thus closing the valve. When the main valve 3 is controlled in response to outlet pressure, the outlet pressure is fed to the Bourdon tube and the valves 29a, 30a are so arranged that a rise in outlet pressure closes the main valve and a fall in outlet pressure opens this valve. In a further modification the movement of the rack rotates the pinion which directly rotates a two or three-way plug valve.

Filed: 1916-03-23
Abstract: 104,566. Brown, S. G. March 23, 1916. Thermionic relays.-In a relay or detector system employing an ionized gas or an electron-discharge device, the temperature of the very fine heated filament is varied by superposing upon a constant heating-current, the current to be amplified or detected. Further variations of temperature of the filament may be produced by causing the amplified current to pass through the filament. In the arrangement shown, the filament B of a device A is heated from a battery d, the circuit D of which contains the secondary winding d<1> of a transformer, the primary winding e of which is in the circuit of a microphone e<1>. The anode circuit F contains a battery f and the primary winding f<1> of a transformer, the secondary winding g of which is in the circuit of a receiver g<1>. The amplified current in the anode circuit F reacts on the circuit D, since a portion of this current passes through the filament B; while a transformer connexion such as H may be placed between the two circuits D, F.

Title: Improved trucks
Inventor: PRICE FRANK STANLEY
IPC: B62B5/04
Filed: 1957-02-08
Abstract: 878,651. Lifting jacks; pallet trucks. YOUNGMAN Ltd. W. C. Feb. 10, 1958 [Feb. 8, 1957], No. 4411/57. Class 78 (3). [Also in Groups XXXI, XXXII, and XXXIV] A trolley having castor wheels, the two rear wheels of which may be locked in a fore and aft position (see Group XXXII), is provided with jack yokes 53 which may be operated by pivoting a handle 34 to lift each wheel and the trolley from the ground. The handle 34 may rotate a shaft 37 to which a pair of levers 38 carrying a roller 39 is fastened, the roller engaging in a cam plate 40 attached to a shaft 41 in three splined parts to allow slight relative movement. Levers 42 fastened to the shaft 41 mount a roller 43 which moves upwardly when the lever 34 is operated to engage the jacks and presses against a pair of levers 44 overlapping at their inner ends and pivoting about bearings 45. At their outer ends the levers 44 carry coaxial rollers 46 on opposite sides of spindles 14 around which the castor yokes 15 rotate, so that upward movement of the roller 43 causes the levers 44 to pivot and press the rollers 46 downwardly against bearing plates 47 attached to the spindles 14, thereby moving the jack yokes 53 downwardly to lift the wheels and trolley. When the roller 43 is lowered to disengage the jacks a U-shaped strap 48 attached to the levers 42 bears down upon the levers 44 and lifts the rollers 46 to engage with upper bearing plates 49 by way of the ball race 50, thus lifting the jacks off the ground and setting the trolley upon its wheels. Catches 35 on the lever 34 enable it to be held in either the operative or inoperative position. In another embodiment a container body or pallet provided with legs may be separably mounted on the trolley, and the trolley when wheeled beneath the container may be provided with means for lifting the container from the ground.

Title: Improved system for guiding dirigible craft, particularly aircraft
IPC: G01S1/02
Filed: 1949-02-18
Abstract: 690,028. Short time intervals, measuring; analogue calculating systems, electric. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Feb. 18, 1949 [Feb. 19, 1948], No. 4541/49. Class 37. [Also in Group XL (c)] In a radio navigation system (see Group XL (c)), the time interval be. tween the passage of a rotating beam of radio energy through a given direction and past a receiving aerial has to be measured. A first pulse is received at the receiver when the beam passes through a reference direction making a known angle α with the given direction and this is applied at C to trigger a multivibrator 1 giving an output pulse I 1  whose rear edge corresponds in time to the passage of the beam through the given direction. The pulse I 1  is differentiated at 2 and the rear edge pulse - I 2  selected at 3 (- I 3 ) and applied directly to circuit 12, 13 and after inversion (+I 4 ) to circuit 6, 7. A second pulse from the receiving aerial is applied at E as the positive pulse I 0 , this is applied directly to circuit 12, 13 and after inversion (- I 5 ) to circuit 6, 7. Normally valves 8 and 14 are non- conductive and in any given time interval measurement one or other of them will remain non-conductive dependent on if a negative pulse is applied to condenser 6 or 12 first. The other valve will be conductive for the time between the application of a positive pulse to the condenser via one input to the time of application of a negative pulse through the other input. The normally symmetrical circuit comprising valves 18 and 19 is unbalanced for a similar time and due to the integrating effect of condenser 24 and the inertia of the apparatus itself measuring apparatus 25 takes up a position in magnitude and sense depending on the time interval to be measured. Computing. Apparatus 25 may carry an arm moving over a potentiometer 26 to give an output potential dependent on the time interval. To obtain a potential proportional to #, where #=KT1T2 - T3 time intervals T1, T2 and T3 are determined in circuits similar to that described with reference to Fig. 2 and used to control the position of the movable elements of potentiometers 26, 27 and 28. Potentiometer 26 is supplied with a fixed voltage so that its output is proportional to T1, this output is applied to potentiometer 27 giving an output T1 T2 which is connected in series opposition with the output of potentiometer 28 to give a final potential of (KT1T2 - T3). In a more complex arrangement, Fig. 5 (not shown), values T1, T2 and T4 are set in on the potentiometers and # computed, it being known that T3=T4 - T2/2.

Title: Improvements in and relating to work-locating devices for drilling, milling and likemachines
IPC: B23Q17/22
Filed: 1938-02-14
Abstract: 511,431. Drilling ; mining. JAMESON, J. L. Feb. 14, 1938, No. 4586. [Class 83 (iii)] A locating device for setting the work in relation to the tool of a boring, milling &c. machine includes two electrical contacts which are adapted conjointly to control an indicator so that the indicator is actuated when the tool and work are in the required position, but one contact or the other is broken to interrupt the operation of the indicator when the relative position of the work to the tool is altered in one or the other direction. The device comprises a bracket 7 carried by a diametrical guide 6 on a circular frame 5 mounted concentrically with the axis of the tool spindle supported in a head 2. An arm 8 depending from the bracket 7 carries an electric contact 9 for engagement with the work 3 and a spring 11 maintains the bracket in engagement with an adjustable electric contact 10 on the frame 5, the adjustment being made so that the end of the contact 9 is exactly on the axis of the tool spindle. An electric circuit is formed as shown in Fig. 1, including the work, bracket 7, a battery 12 and a lamp or bell 13 so that as the work is fed towards the tool axis a reference surface 4 thereon will engage the contact 9 when it reaches the tool axis, thus completing the circuit and actuating the indicator 13, but if the work is moved past this point the bracket 7 will be displaced against the pressure of the spring 11 and the circuit will be broken at 10, thus de-energizing the indicator. The end of the contact 9 may be small so as to engage a selected part of the work only, and the circuit may be arranged so that the indicator is deenergized when the work reaches the required position. The bracket 7 may be pivoted instead of slidable. In order to effect an adjustment of the work in two directions at an angle to each other, the frame 5 is carried by a circular guide 15 on a sub-frame 16 attached to the tool head 2 and is secured in an angularly adjusted position by bolts 17 on the sub-frame passing through arcuate slots 18 in the frame 5. To allow access to the tool the sub-frame is pivoted at 17<1> to the tool head and is secured in operative position by a swinging bolt 18<1> engaging lugs on the head.
