Title: Improvements in or relating to impulse senders for use in telephone or like systems
IPC: H04M1/274
Filed: 1928-10-09
Abstract: 300,498. Associated Telephone & Telegraph Co., (Assignees of Sengebusch, H.). Nov. 12, 1927, [Convention date]. Impulse-transmitters.-An impulse transmitter of the finger-hold type comprises concentric dials controlling separate mechanisms for sending different maximum numbers of impulses. An inner dial (not shown) sends up to ten impulses in the usual way, while an outer dial sends up to 25 impulses and is used for dialling single code digits for frequently-wanted calls over a separate circuit to a register-translator as in Specification 300,497. The outer dial 3, Fig. 4, is fixed to a ring 35 running on ball-bearings around a ring 38 attached to a base-plate 7. The inner edge 42 of the dial overlaps a dust-cover 39 on the ring 38. When the dial 3 is turned it rotates, through gearing 36, 28, 25, a shaft 24 against a spring 47. A pawl 29 on the gear-wheel 25 rides over a ratchet wheel 27 during the setting movement. The ratchet 27 is rotatably mounted on the shaft 24 and is connected to a gear 26, which is in mesh with the drive 22, 21, 15 of a governor 16. When the spring returns the dial, t'he pawl 29 rotates the ratchet 27 so that the governor controls the speed of return. During the return, a cam 20 on the shaft 19 of gear-wheel 22 acts upon the impulse-springs 44 in the usual way to send impulses over the special circuit to the register-translator. When the dial 3 is off-normal, a stop-lever 31, Figs. 2 and 3, is removed from engagement with the pawl 29 under the influence of spring contacts 45, so that the pawl may act freely ; when however the dial approaches normal, a projection 56, Fig. 3, on the ring 35 engages a bent finger 32<1> on the stoplever 31 to force it against the pawl 29 and so act as a positive stop for the dial. The wheel 28 is mounted on the plate 7, but the remaining mechanism is mounted on a removable plate 12 mounted on posts 8, 10 on the base-plate 7. The governor-spindle is mounted in adjustable bearings.

Abstract: 837,664. Reciprocating pumps. MEKLER, D. Sept. 10, 1958 [Sept. 24, 1957], No. 29015/58. Class 102(1). A reciprocating pump comprises a piston 8, reciprocating in a cylinder 5, having a recess 9 in which fits a stationary plunger 17 provided with an axial passage 20 thus forming a low pressure pumping chamber 22 and a high pressure pumping chamber 23. On the suction stroke of the piston 8 liquid is drawn from a supply tank 3 via passages 24b, 24a and non- return valve 26 to chamber 25 from where liquid flows through passage 24 to chamber 22 and past non-return valve 28 and axial passage 20 to chamber 23. On the discharge stroke of the piston 8 liquid is delivered from the chambers past valve 29 to passage 31 which leads to the outlet (not shown). The pressure in the outlet passage 31 also acts on a piston member 36 which opens a spring loaded valve 38 above a predetermined pressure and this valve opens passageways (not shown) which allows the liquid in the low-pressure chamber 22 to be by-passed directly to the tank 3 during the discharge stroke. The valve 38 may be in the form of a cylindrical slide valve and the loading of this valve may be controlled from outside the pump.

Title: Improvements in turbines and compresser rotors
Inventor: PALFREYMAN JACK
IPC: F01D5/28
Filed: 1967-06-24
Abstract: 1,237,532. Forming bodies by winding. ROLLS-ROYCE Ltd. 6 June, 1968 [24 June, 1967], No. 29244/67. Heading B8G. [Also in Divisions B3, C7 and F1] A turbine or compressor rotor is made by winding a continuous fibre or bundle of fibres on to a former 28 in a plurality of passes between locations 29 which are on the circumference of the former and on opposite sides thereof. The fibre passes adjacent the circumference of an aperture 30 at the centre of the rotor between each two opposite locations and is moved radially each time it reaches the circumference of the former. Radially extending fibres forming reinforcing spines for rotor blades are thereby formed integrally with the rotor. As shown, the fibre is fed from reel 21 to a point on the circumference of a planet wheel 22 of an epicyclic gear. The planet wheel is rotated and the fibre which is fed under tension through tube 27 follows an epicyclic path between the pins 29 and then a radial movement (which is not illustrated in Fig. 3) between the pins so as to form the reinforcing spines for the rotor blades (Fig. 4). The fibre can be fed under tension into epicyclic grooves in former 28. The blades can be made hollow for feeding cooling air therethrough. The radial extensions can be formed with loops at their ends, these loops subsequently being cut and bent to extend circumferentially so as to form a shroud for the blade tip (Fig. 4). A plurality of the rotor discs are assembled side-by-side with interposed circumferentially wound fibres. The aerofoil shape to the blades is then formed and the assembly is coated with metal or ceramic. The radially extending fibres may be cut to different lengths to form the blade section. The rotor disc can be filled with a foamed ceramic or resin. Alternatively, the rotor can be formed by moving the fibre circumferentially between radial movements so as to form integral rotor blades, and shroud (Figs. 5 and 6). These rotor discs are similarly assembled with circumferential fibres and resin or electro-plated. The fibre may be carbon, boron or silica. The fibre can be continuous or joined and may be a bundle of fibres. The fibres can be coated with epoxy, polyamide, polyquinoxaline, polythiazole, polybenzimidiazole resins, a ladder polymer, nickel, chromium, niobium, tantalum or chromium/nickel alloy. The fibre coating can be applied before or during winding, e.g. by winding in an electrolytic bath, spraying with molten metal or by vapour deposition. The winding device illustrated can be used to produce similar rotors but not having integral blades. This device and the rotors formed are also described and claimed in the divisional Specification 1,237,533.

Title: Method of calcining diatomaceous earth
IPC: C04B20/04
Filed: 1934-10-15
Abstract: <PICT:0445777/III/1> Diatomaceous earth is treated by intermixing combustible matter with the previously comminuted earth, forming the mixture into coherent solid bodies and subjecting the bodies to treatment with air at a calcining temperature with simultaneous combustion of the combustible matter.  The resulting product is suitable for use as a filter aid, a filler or an insulating material. The whole of the necessary combustible matter may be mixed with the earth or the solid bodies may contain only a part of the fuel, these bodies being passed through a combustion zone in countercurrent to fire gases produced by burning the remainder of the fuel with sufficient air to burn the combustible portion of the intermixed fuel.  A suitable calcining temperature is 1500--1700 DEG  F. Suitable fuels include heavy petroleum distillates, non-asphaltic crude oils, non-caking bituminous coals, lignites, oil shales, diatomaceous shales containing bituminous matter, sawdust &c., anthracite, cokes and carbons.  Earth is introduced from a bin 10 into the suction pipe 11 of a blower 12 in which it is comminuted. The suspension of powdered earth passes through a conduit 13 into a cyclone separator 14, the separated earth passing through a conduit 17 into a suitable mixer such as an elongated pug mill 18 containing revolving blades 19.  A controlled proportion of water or other liquid is fed into the mixer from a tank 21 while a stream of fuel is supplied from a tank 24.  If liquid fuel is used, the water &c., may be unnecessary.  The damp earth is fed from the mixer into slab forming machine 28.  The resulting blocks are fed by an elevator 36 into the top of a shaft kiln 37.  The combustible content of the blocks is burnt in this kiln by means of air supplied by a blower 40. The burnt blocks are removed through a screw conveyer 38.  The kiln is supplied with oil or gas burners 41 for initiating the combustion and, if desired, maintaining the desired temperature and with controlled secondary air supplies at graduated heights such as 44. According to a modification, the blocks are burnt in an inclined rotary kiln, a portion only of the necessary fuel being intermixed with the earth and the remainder of the fuel, e.g. gas, oil or pulverized fuel, being burnt at the outlet end of the kiln.  The resulting earth may be mixed with a semi-fluid such as asphalt for making solid bodies such as battery boxes.  Specifications 173,799, [Class 1 (ii)], and 445,776 are referred to.ALSO:Diatomaceous earth is treated by intermixing combustible matter with the previously comminuted earth, forming the mixture into coherent solid bodies and subjecting the bodies to treatment with air at a calcining temperature with simultaneous combustion of the combustible matter.

Title: Improvements in and relating to the moulding of roofing tiles and like articles
IPC: B28B5/08
Filed: 1947-11-10
Abstract: 652,684. Molding tiles. SAMSON, B., and SAMSON, W. C., (trading as SAMSON BROS.). Nov. 10, 1947, No. 29900. [Class 87 (ii)] Roofing tiles &,c. of concrete &c. are made by subjecting the material while loaded in a mould to a tamping action by an assembly of strickle bars which are reciprocated relatively to the mould, and to a final smoothing action by retaining the bars in a lowered position, in opposition to a lifting force, against the face of the material during the movement of the strickle bars in one direction. The tile 35a is moulded in a mould box 31, its lower face being formed by pallet 35 and its upper face by strickle bars 37 each of which is shaped in accordance with the desired cross-section of the tile. The pallet 35 is adjustably supported upon screw-threaded studs 36. The bars 37 (of cast iron) are attached to members 38 pivoted by pins 38a at their rear ends to arms 40 depending from a reciprocating carriage 11 guided longitudinally on rods 8. Rollers 13 provide bearings between the carriage 11 and bars 8. The forward ends of the bars 38 are rigidly secured to the lower side of a frame 41 having lateral extensions 42 which run on guides 9 and limit the downward movement of the strickle against the material. The strickle may be depressed by means of a handle 46 against the tension of a suspension spring 44. The carriage is reciprocated by means of a crank 19 and rod 21 driven by an electric motor 56 controlled by foot pedal 18. Upon completion of the tamping and smoothing action the pallet with the tile on it is ejected by means of a rod 51 which contacts a loose ejector plate 52. The rod is operated by a foot pedal 54. The apparatus may embody a circular turntable 24 carrying two, three or more radially disposed mould boxes 31 each having its own ejector 51 adapted to project through apertures 53 in the turntable. The turntable may be locked in position by means of a turret pin 26 which engages holes in the table rim. A pin (not shown), on a length of chain secured to each moulding box is passed through a hole in the pallet to form a tying wire hole 50a, Fig. 7, in a projection on the under side of the tile.

Abstract: 622,842. Endless-belt conveyers. M. & C. SWITCHGEAR, Ltd., and MORRISON, R. Oct. 8, 1946, No. 29979. [Class 78 (i)] [Also in Group XXXVII] A conveyer in which a circuit controls the starting and stopping of the driving means and a speed switch is operated by the conveyer to be closed only when the speed is above a predetermined amount has a relay coil in the circuit and also in parallel with the speed switch and contacts which are opened by energisation of the coil, but which, when closed, short circuit the speed switch and a time lag device controlling the opening of the contacts for sufficient time to enable the speeding up of the conveyer to close the speed switch whereby also when the conveyer is caused to slow down the speed switch opens and breaks the control circuit stopping the conveyer. As shown in Fig. 1 the delivery conveyer K has a speed switch D and a driving motor G, controlled by a circuit including the normally closed contacts C<SP>1</SP> of a relay C. The circuit is connected to the mains through the coil of a relay B and a speed switch A of a receiving conveyer M and a current overtrip V. The coil of the relay C is in parallel with the coil of 'relay B, and the normally open contacts B<SP>1</SP> of relay B in series with contactor coil J are in parallel with the motor control circuit. In operation, the receiving conveyer M is driven to working speed the switch A closes and the coils are energised opening contacts C<SP>1</SP> and closing contacts B<SP>1</SP> thus starting the delivery conveyer K. A time lag on contacts C<SP>1</SP> enables the starting of the motor before the speed switch D is short circuited. If the receiving conveyer M is stopped the speed switch is opened and the relays are de-energised. The contacts B<SP>1</SP> open and the conveyer M is stopped. The contacts C<SP>1</SP> close to permit sequence restart. A manual switch F can eliminate sequence control. Any number of tributory conveyers feeding in parallel onto a common receiving conveyer may be sequenced in a similar manner. If the belt of conveyer K should break and the speed decreases, the speed switch D opens and the coils are de-energised. The contacts B<SP>1</SP> open and the conveyer stops. The contacts C<SP>1</SP> are maintained open by a latch connecting the two and can only be manually reengaged to permit normal working.

Title: Guidance system for an anti-aircraft missile
IPC: G05D1/12
Filed: 1973-06-25
Abstract: 1441127 Guidance system BOFORS AB 25 June 1973 [26 June 1972] 30171/73 Heading F3C  A guidance system for an anti-aircraft missile 2, which is launched from a sighting device 3 having a sight line S rotatable about an azimuth axis and an elevation axis perpendicular to the azimuth axis, the sighting device intended to be pointed at a target throughout the guiding operation. The missile launcher 1 is integral with the sighting device 3, and the launcher 1 is parallel to the sight-line S which, as shown, in Fig. 1 contacts a target M at an instant I; in this instant the missile 2 is launched, After the launching the sight-line S is maintained on the moving target M and the deviation of the missile 2 from the sight-line S is continuously determined by equipment (not shown) and passed to flight control means (not shown) to change the missile direction and reduce this deviation. Thus the missile flies in a curved path towards the target. The signals show the deviation in two pre-selected, orthogonal directions relative to the sight-line, generally in the horizontal and vertical directions, the flight control means having the vertical direction indicated by a gyroscope mounted in the missile and, consequently, also having the horizontal direction indicated. Since the sight-line is rotated in azimuth and in elevation away from its direction at the instant of launch the horizontal direction relative to the sight line will diverge further from the yaw control plane of the missile as determined by the gyroscope. Similarly the vertical direction will diverge from the pitch control plane of the missile. This means that signals representing deviations of the missile from the sight-line in the horizontal and vertical directions respectively cannot be used for controlling the flight of the missile in the yaw and pitch planes as determined by the gyroscope as the missile would be formed to move in a helical flight path about the sight-line. The difficulty is overcome by continuously rotating the co-ordinate system about the sight-line during the guidance of the missile towards the target. In use signals representing the deviation of the missile from the sight-line in the horizontal and vertical directions can be converted into the desired yaw and pitch control signals b use of known co-ordinated transforming circuits. Systems for determining the deviation of the missile from the sight-line and for producing control signals representing this direction for the flight control means of the missile include (a) an optical sight, (b) photodetectors and optical means for projecting an image of the missile or of a light source on the missile upon these photodetectors, and (c) a sighting device associated with a radiation transmitter which emits an electromagnetic guidance beam in the direction of the sight-line.
