Title: Improvements in or relating to detachable objective mounts for photographic apparatus
Inventor: KUHNERT RUDOLF
IPC: G03B19/18
Filed: 1960-10-17
Abstract: 915,335. Focusing lens mounts. KAMEBAUND KINOWERKE DRESDEN VEB. Oct. 17, 1960, No. 35481/60. Class 97 (1). A detachable objective mount for photographic apparatus comprises support means adapted for connection to the apparatus housing, a spindle supporting the objective lens carrier and axially adjustable in the support means for focusing, and a rotatable locking- device which, in one direction of rotation, acts to secure the objective mount to the apparatus housing, and in the other direction looks the spindle in relation to the support means. As shown in Fig. 1, the objective lens carrier 3 is rotatably mounted on a spindle 1 and held against axial displacement by parts 4 rigid with spindle 1. The latter extends through a bush 6, in which it has threaded engagement, and through a sleeve 8 rigid with bush 6 and carrying scale markings 9 for focusing purposes in cooperation with markings on the milled head 10 of spindle 1. A ring 12 rotatably mounted on sleeve 8 carries keys 13 for bayonet connection with a corresponding part 21 of the projector, and has a recess 14 (Fig. 3) in which is fixed a leaf-spring 17. A pin 15 extends through a slot in sleeve 8 and, when the objective mount is detached is pressed by leaf-spring 17 against spindle 1 to prevent rotation of the latter and thus preserve the previous focus setting. On attachment to a projector, a groove 2 of the objective carrier 3 is engaged by a pin to prevent rotation, and a key 18 on sleeve 8 engages a corresponding part 20 on the projector to hold sleeve 8 against rotation. As ring 12 is then rotated to make the bayonet connection, the relative movement between pin 15 and the helical boundary of recess 14 releases the constraint on spindle 1 to allow further focusing adjustment.

Title: Improvements in or relating to metal or other grinding or cutting machines
IPC: B24B49/04
Filed: 1938-12-08
Abstract: 523,199. Grinding and polishing. LUND, J. Dec. 8, 1938, No. 35749. [Class 60] [Also in Group XL] The feed of a grinder 10, Fig. 2, towards work 11 is stopped when the work is reduced to a predetermined size, as ascertained by feeler 38, but grinding continues due to elasticity of the work, and after a further reduction in size, the grinder is withdrawn from the work. The feed of the grinder is effected by pistons 22, 35, Fig. 3, the supply of fluid to which is controlled .by electromagnetically actuated valves 80, 81 controlled over a thermionic valve circuit, Fig. 6, by movement of an armature 43 connected mechanically to the feeler 38. With the valves 80, 81 in the position shown, the piston 22 is urged to the left, to move the slide 15 with a fast initial feed towards the work. Piston 35 is urged to the right, and through rack and pinion gearing rotates piston rod 21 to screw pin 19 to the left, and thus imparts a slow final feed to the slide 15. At the first predetermined size, valve 81 is turned to dotted line position, thus placing both sides of piston 35 to exhaust and so arresting any further movement thereof. At the final size the valve 80 is turned to dotted line position, thus applying pressure to the pistons so as to move 22 to the right and 35 to the left and so withdraw the grinder from the work. Movement of the armature 43 alters the balance of an AC bridge comprising coils 45, 46, 51 and 52, the rectified output being applied to the grid of a pentode 59. The output of the pentode is applied to the grids of valves 60, 61 which are differently biassed by potentiometers 64, 65. These valves become conducting at different positions of the armature 43, and through the intermediary of relays 70, 71 in their anode circuits, and contactors 72, 73 control the electromagnetically actuated fluid valves 80, 81.

Title: Improvements in liquid measuring and delivering devices
Filed: 1938-12-13
Abstract: 522,490. Liquid-dispensing devices. WAYNE TANK & PUMP CO.. Ltd., and WELLS, F. J. Dec. 13. 1938, No. 36312. [Class 116] [Also in Group XXIX] A liquid-measuring and dispensing apparatus has means for automatically affecting a cessation of delivery at a predetermined position of the indicating mechanism subsequently to the operator reducing the rate of delivery to or below a predetermined amount. The delivery valve, preferably of the multistage type adapted to give either a full or dribble feed, is coupled to a rod 11 which is moved to the open position when the operator sets the measuring apparatus to zero and is held in the open position by a series of catches 9, 20, 21 co-operating with arms 12, 13, 14 rigidly secured to a shaft 4 connected by a crank arm 10 with the rod 11. The catch 20 is released by a cam 15 adjustably secured by screws 18 to a pin 19 carried by an arm fixed to a shaft 2 connected by a universal joint to the unit gallon or money shaft of the counter mechanism of the liquid measuring pump. The catch 21 is released by a cam 16 loosely mounted on the shaft 2 and having a lost-motion connection with the pin 19. The catch 9 is released by a plunger 7 operated by a spring-loaded diaphragm 8 subject to the pressure in the delivery hose. The several catches are held in engagement with their releasing mechanisms by pendulous weights a, b, c. To effect a delivery after the measuring apparatus has been set to zero, the operator opens the nozzle valve on the end of the delivery hose. As the measuring pump turns the cam 15 releases the catch 20 and allows the shaft 4 to rotate slightly to bring the arm 14 into engagement with the catch 9. When the delivery of the last unit has commenced the operator momentarily closes the delivery cock so causing the pressure to rise in the delivery hose and release the catch 9 leaving the shaft 4 held against rotation by the engagement of the catch 21 with a projection 13a on the arm 13. As the delivery of the last unit nears completion the cam 16 releases the catch 21 from engagement with the projection 13a. This permits the shaft 4 to rotate to reduce the delivery to a dribble, the shaft 4 being held in this position by the catch 21 engaging a projection 13b on the arm until the unit is completed, thereupon the projection 13b is released and the delivery valve closes. Specifications 461,568 and 478,129 are referred to.
