Title: Improvements in and relating to gun-directing apparatus
IPC: F41G5/08
Filed: 1945-08-03
Abstract: 705,362. Gun-directing apparatus. SPERRY GYROSCOPE CO., Inc. Aug. 3, 1945 [March 15, 1943], No. 20072/45. Class 92(2)  Apparatus for directing guns used against moving targets comprises means for comparing the target's future position-after the projectile flight -as determined by data obtained by target following apparatus, with the calculated position of the shell burst, as determined by the outputs of devices controlling the fuze-setting or the laying of the gun, any differences arising from such comparison resulting in the automatic control of said devices so as to bring the positions of the shell burst and target's future position into coincidence. In the construction shown a radio sighting system 1, as in Specification 621,485, is used for automatically following the target and serves to produce voltage signals in leads 2, 3 corresponding to the present azimuthal and elevational angles of the target and to produce on a lead 5 information enabling a range circuit 4 to give on a lead 6 a voltage proportional to the slant range. The three leads 2, 3, 6, give their data to a converter 30 whose outputs 31, 32, 33 have voltages corresponding to the rectilinear co-ordinates of the target, and these three outputs in turn lead to a prediction circuit 29 which is fitted also with parallax connectors 77, 78, 79 and with a " time of flight" input shaft 34. The voltages on the three outputs 35, 36, 37 of the circuit 29 correspond to the predicted future position of the target and are compared in a difference indicator 56 with the shell burst position as given by leads 53, 54, 55, and any differences appear as voltage signals in leads 63, 64, 65 connected to servos 66, 67, 68, such signals representing errors in polar co-ordinates. The output shafts 39, 40, 41, of the servos 66, 67, 68, respectively represent time of flight, quadrant elevation, and angle of train, and are used to actuate appropriate transmitters 72, 74, 75 which transmit the required information to the guns on leads 73, 76, 28. The transmitter 72 is associated with a fuze converter and corrector as, in Specification 609,707. Shafts 39, 40, 41 also serve to drive the inputs of ballistic mechanism 38 which applies correctons so as to give on its outputs 49, 50, 51, data corresponding to the true position of the shell bursts, such outputs being fed to a converter 52 which by its outputs supplies the indicator 56 with the shell burst position in rectangular co-ordinates. The Specification describes various circuits for adding, subtracting and multiplying data supplied, and uses these circuits in the various devices shown in the drawing for obtaining the required outputs. Specification 418,670 also is referred to.

[Class 44] [Also in Group XIV] A device for preventing displacement of drawers and the like in an aircraft galley, comprises a pair of channel members 11, 12, Fig. 1, fixed to a cabinet frame and securing a channel section housing 16 in position. A latch 20 is pivoted to the housing 16 by a pin 21 and its lower end normally engages teeth 19 formed on the rear end of the cover 17 of a drawer 18. One end of a rod 26 is hingedly attached to a bracket 23 on the latch 20 whilst its other end extends through an aperture in the rear wall 27 of member 11 and is provided with a press knob 28. A spring 31 compressed on rod 26 between the wall 27 and a washer 32 which is adjacent knob 28 urges rod 26 outwardly. This movement is limited by the latch 20 engaging teeth 19 and also by a shoulder 33 on the knob 28 contacting the front wall 30 of member 11 through which the knob passes. The front of cover 17 is prevented from chattering by means of a cam 39 which engages the top of the cover 17. The cam 39 is secured by a set screw 40, Fig 4, to a rod 37 whose rear end rests in an opening 38 in wall 27 and whose forward end is furnished with a button 34 which extends through an aperture in wall 30. On pressing inwards the indented head 35 of button 34 against the action of a compression spring 43 on the end of rod 37, a gear 41 which is rigid with cam 39 is disengaged from a sector gear secured to a mounting bracket 44. The rod 37 is then free for rotation and. consequent disengagement of cam 39, whereupon the front of cover 17 may be lifted to abut the inturned lip 49 of wall 30 and the drawer 18 is released from the shortened front edge 50 of cover 17. To remove the drawer 18 with its cover 17 the button 28 is pressed to release latch 20 from teeth 19. In a modification the teeth 19 are applied to or carried by an integral top wall or side of the drawer.

Title: Improved machine for digging trenches
Inventor: CRAMPTON JAMES RICHARD
IPC: E02F9/22
Filed: 1968-05-01
Abstract: 1,211,757. Endless chain excavators. J. R. CRAMPTON. 1 May, 1968 [2 May, 1967], No. 20679/68. Heading E1F. In a trench-excavating machine having digging tools mounted on endless chains circulating about a vertically swingable boom pivoted on a crawler track-mounted chassis all the movements of the operable parts of the machine are hydraulically controlled and the hydraulic circuitry involved is such as to permit of automatic regulation of the movements of said parts in accordance with any variation in operating conditions encountered by the machine. The hydraulic actuators of said parts are motors 29, 30 for driving the tracks 31, 32 of the machine, motors 5, 6 for driving the endless chains, motors 88, 89 for driving an endless belt ejector provided in the machine for ejection clear to one side of the machine of material dug up by digging tools mounted on the endless chains, jacks 82, 83 controlling the vertical position of the telescopic boom and a jack 68 for maintaining a desired tension on the endless chains during extension or contraction of the boom. The circuitry is such that there is, where the machine is digging, automatic regulation of the low speed advance of the machine in accordance with the resistance to digging encountered by the machine. The parts of the circuitry then involved are a small output pump 28, a distributor 33, a flow regulator 34 dividing and directing flow from the pump to either the motors 29, 30 through distributor 35 and/or to the supply circuit of motors 5, 6 through valve 52 and distributors 10, 12. The regulator 34 involves a throttle valve, the setting of which is determined by the pressure in the supply line 8 coupling the motors 5, 6 as this pressure is a measure of the resistance encountered by the digging tools. For faster traversal of ground when the machine is not digging the motors 29 and 30 are powered from two pumps or a duooutput pump 3, 4 of large capacity through distributors 9, 10. When the machine is digging power from these pumps is solely directed through the distributors 9, 10, 11 and 12 to the motors 5, 6. When the digging load on the motors 5, 6 approaches the available power from the prime mover 1 driving the pumps 3, 4, 28 and 10 of the circuitry a regulator in the feed circuit of the motor 6 directs the flow to this motor to the reservoir of the circuitry so that the hydraulically shunt-connected motors apply more torque at a lesser speed of rotation to the endless chains. Pump 100 drives ejector motors 88, 89. Overload valves are provided in all parts of the circuitry.
