Inventor: HOWARD-SMITH ANTHONY
IPC: E05C19/04
Filed: 1957-03-16
Abstract: 829,345. Catch fastenings. SMITH & DAVIS Ltd. March 3, 1958 [March 16, 1957], No. 8745/57. Addition to 761,819. Class 44 A spring catch for a door or the like for non-prohibitively retaining the door or the like in a closed position comprises a bolt 18 which is resiliently urged forwardly to stop means into an extended position and includes on its forward or nose end a roller 31 to co-operate with a catch plate or the like, the roller being offset from an opening 28 extending rearwardly in the bolt from its forward or nose end to adjustment means to afford free access of a screwdriver or other tool to the adjustment means to operate said adjustment means to vary the position of the stop means and thus the amount of projection of the forward or nose end of the bolt beyond the front of the catch body 10. As shown in Fig. 3 the bolt is urged to its extended position by a coil spring 30 which is trapped between a shoulder 21 on the bolt and a fibre nut 29. The nut is threaded on to a screw 26 which forms both the adjustment means and the stop means and which passes through a hole in the end wall 25 of the bolt so that its head is in the opening 28 and its underside forms the stop means; the stem of the bolt threadedly engages the end wall 16 of the body 10 so that the amount of projection of the bolt can be varied. The bolt is provided with two arms 24 and as shown each carries a roller 31 there being a space between the rollers to provide access to the opening 28. The fibre nut 29 enables the compression of the spring 30 to be adjusted. In a modification, Fig. 8, a single roller 31 is carried by the arms 24 but the two arms are cranked so that the pivot of the roller is offset from the longitudinal axis of the bolt to enable the screwdriver or other tool to engage the head of the screw 26. To accommodate the arm 24 and the roller 31 the body 10 is slotted at 36 on one side of the body. To reduce the amount of offset the roller 31 may be provided with an annular groove.

Title: Improvements in or relating to automatic rammer mechanisms for guns
Inventor: SHONTS JAMES GODDARD
IPC: F41A9/42
Filed: 1950-04-11
Abstract: 784,739. Ordnance. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 11, 1950, No. 8835/50. Class 92 A rammer mechanism for a gun comprises a case 10 which is movable in an arcuate path from an ammunition-receiving position to the position shown, where it delivers the round 21 by free-flight delivery to the breech of the gun, the case 10 being provided with centering and supporting means for the round and means also. serving to direct the course of the round in its frceflight towards the breech. The case 10 shown has pivoted to it upper arms 23, 55, and lower arms 57, 62, all of which are pivoted at their other ends to form a parallel-link system. The upper arms are linked together at 47, 51, 53 to rotate in unison, and a branch 29 of the arm 23 is connected by a beam 34 pivoted at 35 to a pivoted lever 36, to the piston rod 43 of a hydraulic actuator 44. The actuator thus serves to move the case 10 to and frbm the receiving and ramming positions, the receiving position being located in front of a conveyer 172 fitted with cam-controlled clamping mechanisms and timed to deliver the rounds in sequence to the case. When a round enters the open end 11, Fig. 5, of the case its rim encounters abutments 89 on three circumferentially spaced toggle levers 85 which are pivoted at 84 to the case and which are linked to a spring- controlled sleeve 74. The toggle levers are thereby moved past a dead-centre position to bring rollers 87 thereon into a position where it engages and guides the round. The movements of the sleeve 74 during this action serve to actuate a further toggle system 141, 144, to bring a roller 147 into engagement with the round, the function of this roller being to counteract the effects of centrifugal force tending to disturb the round during the swinging movement of the case 10. As the rim of the round approaches the closed end of the case it comprises a buffer 12 and also rides over a spring-controlled latch 127 which then serves to hold the round in position. Fluid is then supplied to the actuator 44 to swing the case 10 to its ramming position, Fig. 2, the actuator being so arranged as to buff the movement of the case as it nears the end of its stroke. Towards the end of this stroke a cam 118 which is mounted on the pivot pin 20 of the arm 57 and which hitherto was clear of a roller 117 is rotated to engage the roller as shown in Fig. 5; the resultant movement of the roller serving to move a cam which in turn moves the latch 127 to free the round. The latter is now ejected from the case 10 by the buffer 12 being guided at first by the rollers 87, 147. As the rim of the round leaves the case it reaches the toggles and at the same time energizes an interlock associated with the actuator 44 to cause the parts to return to the initial position. Spent cases are received by a movable deflector shoot 69, Fig. 2, secured to a link 68 whose movements are controlled by an arm 66 of a bell-crank 64 whose other arm 63 is secured to the support arm 62.

Title: Improvements in and relating to adjusting devices for the abrasive elements of grinding machines
IPC: B24B33/10
Filed: 1934-03-22
Abstract: 429,799. Grinding cylinders. THORNTON, A. A., 7, Essex Street, Strand, London.- (Bertoni & Cotti; Copparo, Ferrara, Italy) March 22, 1934, No. 8991. [Class 60] In a cylinder honing apparatus comprising radially-adjustable abrasive elements carried by a head which is rotated and reciprocated by a hollow driving shaft, an adjusting device which is carried by a fixed support and does not take part in the movements of the head produces relative movement between the hollow shaft and a rod co-axially arranged within it to effect the radial displacement of the abrasive elements. In the apparatus shown, a tubular driving shaft 47, rotated by a gear 72 and reciprocated by means not shown, is connected by a member 77 having ball joints at the ends to the honing tool or head, in which are mounted the radially adjustable holders 76 for the abrasive elements. The elements are adjusted by rotation of a screw 73 which causes axial movement of conical wedge members 74, the screw being attached to a rod 36b, connected by telescoping parts 36a, 36, 27 to a squared rod 26 which is rotated by a bevel gear 22 mounted in the upper part of a fixed casing 6. The gear 22 is rotated through gears 21, 16, 13, 12 and 2, of which the pinion 12 is trunnioned on a collar 8 fixed in the casing 6 and the pinion 21 on a collar 17 rotatably mounted in it. The gear 2 is carried on the top of a sleeve 1 to the bottom of which is secured the gear 72 driving the shaft 47, with the result that, when the collar 17 is held from rotation, the rod 26 is rotated at the same speed and in the same direction as the shaft 47 through the similar gear trains 2, 12, 13 and 16, 21, 22, the first train serving merely to prevent the reversal of motion which would occur with one train. During such operation, therefore, the rod 26 acting through the telescoping members in the shaft 47 rotates the adjusting screw 73 in the honing tool at the same speed as the head, maintaining the adjustment of the abrasive ' elements. To adjust the elements the rod 26 is rotated relatively to the shaft 47 by rotating the collar 17 on which the pinion 21 is trunnioned, causing the pinion to move as a planetary member and alter the relative rotation of the gears 16, 22. For this purpose the collar 17 is secured to a rotatable ring 15 having peripheral teeth engaged by a gear 25 which is rotated through helical gears 31, 32 from the adjusting device shown in Fig. 2. This comprises a rotatable disc 35 secured to the shaft 33 of the gear 32 and provided with a spring- pressed locking pin 61 engaging holes in a plate 56 and a withdrawable stop 66. The adjusting device is mounted on the lower part 6<a> of the casing.

Abstract: 480,216. Centrifugal separators. AKTIEBOLAGET SEPARATOR. March 30, 1937, No. 9022. Convention date, April. 4, 1936. [Class 23] The skim milk and cream separated in a centrifugal separator pass from the bowl to chambers 4, 8 from which they are withdrawn by skimming or immersion apparatus 5, 9. The level in one of the chambers is rendered *largely independent of the level in the bowl, by the passage of the liquid component in that chamber over a level outlet or through a throttled channel from the bowl. The skim milk, for instance, passes up the channels 1 to the chamber 4. over a weir edge 2 in the bowl neck. Or, as an alternative, where the liquid surface is farther than the edge 2 from the axis, the skim milk passes through a narrow opening 11 in the weir; the supply to the chamber 4 is then increased as the level 6 in the chamber is displaced outwardly. Instead of the opening 11 a throttled channel 13 may be arranged for the passage of the cream from' the bowl to the chamber 8, or a narrow slit 15 may be arranged in the ring 14.

Title: Vehicle guidance system utilizing conical scan control beam
IPC: F41G7/26
Filed: 1973-02-23
Abstract: 1378842 Photo-electric guidance systems NORTHROP CORP 23 Feb 1973 9060/73 Heading H4D In a vehicle guidance system a conically scanned electromagnetic guidance beam is transmitted from a control station, a reference signal generated in the vehicle to be guided being phase locked with a reference signal generated in the transmitter and supplied via an umbilical to the vehicle, prior to separation of the vehicle from the station. In the described embodiment a mutated laser beam is transmitted from a unit (11) (Fig. 1, not shown) and a photo-cell in a missile (15) detects the beam. The transmitter (Fig. 5) comprises an oscillator 41 which feeds frequency divider circuits 42 and thus supply a motor 26 with drive signals. The motor rotates a mirror 24 which rotates the beam from laser 20. The mirror is mounted on a disc 30 having an aperture 30a, through which the light from source 35 may pass and impinge on sensor 37. The sensor feeds an amplifier 48 which thus provides synchronization pulses. The receiver comprises a photo-detector 58 which receives the mutated beam. The resulting signals are fed to amplifier 59 which feeds phase detectors 54, 56. The detectors compare the phase of the received signals with direct and 90 degree shifted reference signals obtained from an oscillator 51, via divider circuits 52, the signals from the divider circuits being phase locked with the transmitter synchronization pulses via an umbilical cord prior to launching. The detectors provide control signals to keep the missile centred on the beam during flight. As the oscillator 51 is highly accurate and stable, synchronization is only needed prior to the flight, the umbilical being disconnected prior to or upon launch. Further embodiments of the transmitter and receiver, which substantially eliminate noise in the laser beam, are described. In these embodiments, the beam is split into oppositely polarized components which are subtracted in the receiver to cancel any noise components.
