Abstract: 1,232,277. Operating levers. MESSERSCHMITT BOLKOW BLOHM G.m.b.H. 22 May, 1968 [24 May, 1967], No. 24490/68. Heading B7E. [Also in Division F2] A working member 17, for example a brake, is actuated from an operating lever 19 by a bar 22 which carries a pin 24 engaging in a slot 23 which is eccentric with respect to the lever pivot 20, the member 17 being held in a stable rest position, where the brake is applied, under the combined action of a leaf spring 21 and a helical spring 25 which applies force to lever 19 by way of sleeve 26 freely slidable on bar 22, pin 28, plunger 29 and connecting link 32 to lever projection 34. When the lever is operated manually to release the brake, the operating force acts against the combined leaf and helical spring forces until projection 34 reaches top centre. Thereafter the helical spring opposes the leaf spring allowing the brake to be maintained in its astable inoperative position by only a small force applied to lever 19. The position of pivot 20 may be set by an adjustment screw 36. An application of the invention to a missile launching apparatus is described with reference to Fig. 1 (not shown), in which two mechanisms as shown in Fig. 2 are employed to secure the apparatus in adjustable positions about horizontal and vertical axes.

Title: Battery charging system
IPC: H02J7/00
Filed: 1970-12-29
Abstract: 1316169 Charging batteries SINGER CO 29 Dec 1970 61547/70 Heading H2H A battery charging system comprises means whereby the charging rate can be varied in dependence upon the overall temperature of the battery and the temperature of an individual cell of the battery. A battery 1 is charged from an A.C. source 10 by way of a transformerrectifier unit and two switching circuits 40, 70, the circuit 40 being effective to allow the battery to be charged when the battery temperature is within predetermined limits-say 0-50 C.- and the circuit 70, in the form of a Schmidt trigger circuit, controls the high and low rate charging of the battery in accordance with the temperature of an individual cell. The battery 1 is formed by a plurality of "active" cells and one passive cell having a heater 9 associated therewith, the heater 9 being connected in the battery discharge circuit, a thermistor 88 being associated with the passive cell and placed in the switching unit 70 so that a high battery discharge current does not distort the operation of the switching circuit 70. Two thermistors 52, 54 are located to sense the overall temperature of the battery 1 and when the battery temperature is within the desired limits the resistances of the thermistors are such that the transistors 42a, 42b, 58 function to make a transistor 60 conductive thus placing a conductor 62 at a D.C. potential. Thermistors 82, 84, 86 are located to sense the temperatures of "active" cells in the battery 1 and these thermistors together with thermistor 88 located in the "passive" cell, are effective to control a transistor 72a. Whilst the temperatures of these cells are normal the thermistors function such that transistor 72a is "OFF" and transistor 72b is "ON". This causes a transistor 90 to conduct which then turns transistors 100, 102 on. Transistor 102 carries the battery charging current and since a resistor 104 is of low value a high charging current results. When the battery 1 is fully charged, the temperatures of the active cells become higher than that of the passive cell when the conditions of the thermistors 82-88 as such to switch the circuit 70 to its other state. Thus transistor 102 is turned off and the high charging current terminated. A transistor 108, in parallel with the transistor 102, is turned on whenever the conductor 62 is energized, thus a trickle charge by way of a high value resistor 110 is always maintained. Should the battery become so charged that gassing begins, a Zener diode 122 breaks down to render a transistor 120 conductive which in turn cuts off transistor 108 to terminate the trickle charge process. When the circuit 70 has been switched to its other state to terminate the high charging current the circuit is so arranged that it is necessary to switch off the main supply 10 to reset the circuit. If desired the circuit 40 may be similarly arranged.

In the construction shown the member 15 is made from a rod tube or strip of spring steel and it is so constructed that when the lever is moved to withdraw or shoot the bolt it is laterally displaced resiliently to serve as a spring biassing means to bias the bolt into both the shot position and the retracted position alternately by bearing against a strip 22 secured in the recess in which the member 15 is disposed. The bolt is connected to the linkage means either by screw thread or by adhesive.

Abstract: 1327806 Microwave oven TOKYO SHIBAURA DENKI KK 19 Nov 1970 55131/70 Heading H5H Leakage of microwave energy from the cavity 12 of a microwave oven is prevented by forming the door 16 from an inner resilient metal plate 19 which resiliently electrically contacts the metal periphery 12a of the oven opening, and an outer metal plate 18 spaced from the inner plate 19 and provided with an edge 18a bent at two points to provide a lip parallel to and spaced from the major surface of plate 18 so that a window of width "X" is formed brtween the periphery of inner plate 19 and the edge 18a of plate 18, the distance between the centre of the window and the uppermost part of the outer plate being <1/4# and the distance between the centre of the window and the point of contact of the inner plate 19 with the door opening periphery being =#/4. The size "X" of the window opening is between #/10 and #/40 and is greater than the gap "y" between the lip and periphery 12a of the oven opening, the distance "y" being between 0 and #/40. Thus any energy escaping through the point of electrical contact between the periphery 12a and resilient edge 19a of plate 19 is absorbed in the peripheral cavity 21 formed in the door. The cavity may contain a resilient energy absorbing dielectric 21a or may be delineated by a resilient metal plate bridging the front and rear plates 19, 18 of the door at the point of contact of the resilient edge 19a of plate 19 and the periphery 12a of the oven opening. In other embodiments the microwave window in the door may be closed by microwave transparent dielectric material to prevent foreign matter entering the door. As the point of contact of the periphery 12a of the door opening and resilient edge 19a is approximately #/2 from the wall A of the door cavity the electric field at this point is weak and sparking is prevented.
