IPC: G06M1/10
Filed: 1956-09-05
Abstract: 871,615. Electric tests. BURNDEPT Ltd. Dec. 5, 1957 [Sept. 5, 1956], No. 27204/56. Class 37. The presence of a body is detected by a tuned anode-tuned grid oscillator the reactance of one of the tuned circuits of which is so modified by the body that oscillation ceases. As shown, the oscillator comprises triode having crystal 2 and resistor 3 in the grid circuit and tuned circuit 4 in series with the anode. The body to be detected, e.g. a dry cell brought by a conveyer to a filling or sealing device increases the capacitance to earth of plate 11 connected to the anode of the triode so that oscillation ceases. The increase of current in the anode circuit operates a relay 14 connected between the potentiometer tapping and the junction of resistor 5 with the tuned circuit to effect any desired control and to connect capacitor 19 into the anode circuit so ensuring that oscillation restarts when the object moves away. Movement of the relay armature may reduce the capacity between the armature and an adjustable plate 22 connected in parallel with the anode capacitance.

Title: Impulse controlled escapement mechanism
IPC: G06M1/10
Filed: 1946-09-11
Abstract: 623,646. Counting-apparatus. PRODUCTION INSTRUMENT CO. Sept. 11, 1946, No. 27310. Convention date, Sept. 28, 1945. [Class 106 (i)] [Also in Group XXIV] An escapement mechanism is shown applied to a counting apparatus subjected to electrical impulses from a source 25 and switch 26 which are indicated on number wheels 23. The drive shaft 13 of the apparatus is driven through an elastic coupling 12 from a shaft 11 and is itself coupled through a spring device 64 with an escapement element 80. This escapement element carries axially disposed pins 62, 63 (see also Fig. 3) alternately extending from side flanges 60, 61 to overlap. These pins are alternately engaged by radial pins 45 on a control member 44 which is supported on flexible diaphragms 35, 36 and is adapted to be pulled downwards against a spring 50 on the energization of a coil 34 carried thereby on closure of the switch 26, the coil 34 moving into the space 33 of an electromagnet 14, 15 energized by a source 31. On this downward movement of the control member 44 the pins 45 move from the full line position shown in Fig. 3, where they engage pins 62, to the dotted line position, which movement allows the escapement element 80 to rotate a small amount until the pins 63 engage the pins 45. On opening the switch 26, the member 44 is released to move upwards and move pins 45 from pins 63 back to pins 62, thus allowing another small rotary movement of the escapement element. Thus, impulses derived from opening and closing the switch 26 produce successive increments of rotation of the shaft 13 which is suitably geared to operate the counting discs 23.

[Class 110 (ii)] [See also Group XXIX] A rotary engine, pump, or compressor, of the intermittent abutment type has segmental pistons 3 moving around an annular chamber bounded by the casing which forms abutments 18, 19, and 20, 21, and an inner guide cylinder 2. Rollers, approximately circular, or balls 15, in one or more pairs, extend axially slightly beyond the piston ends, and are gripped by pressure plates 4, which are secured between nuts 8 and a collar 7 on the shaft 6 on which they are keyed. The rollers roll on the plates 4 and cause the radial movement of the pistons 3 during their passage around the chamber. Angular-shaped grooves may be provided in the plates 4, and the rollers 15 make contact with the sides of the grooves. The end faces of the pistons lie on radial lines passing through the centre of the casing, which lies at a distance E below the centre of the shaft 6. In a modification the end faces of each piston are arranged so that the resultant pressure vector passes through the point of support of the piston or centre line of the rollers. When the machine is used for gas compression, the delivery port is considerably smaller than the inlet. A modification describes the use of two axially-displaced working chambers separated by a pressure plate. The invention may be applied to a hydraulic gearing, Fig. 21 comprising a pump with a sliding casing 29 to vary the eccentricity of the rotor, and a second machine upon a shaft to be driven by the liquid pumped, the latter having a chamber of fixed eccentricity. The pump may have a fixed eccentricity and the casing of the motor be slidable, or both may be variable.

Abstract: 492,629. Turning-gear. BOSCH AKT.- GES., R. Oct. 13, 1937, No. 27795. Convention date, Oct. 22, 1936. [Class 7 (v)] In an engine starter in which a pinion d or other driving member is connected by a freewheel clutch e to a sleeve f threaded on the shaft a of the starting motor and displaced manually by means of a collar n, axial displacement of the sleeve f on the shaft a is prevented, when the pinion d is in engagement with the engine gear z, by a locking member u, the position of which is influenced by the collar n. As shown, the clutch e is a disc clutch adapted to be tightened by a nut i threaded on the sleeve f. The collar n is in two parts q, r cushioned by springs o, p and adapted to engage a stop ring s on the shaft a. The collar is actuated by a lever y adapted to actuate the switch of the starting motor. The locking member u is a ball co-operating with a groove v in the collar part r and grooves w, x in the shaft a. In the disengaged position shown, the ball u engages the groove x and prevents accidental movement of the sleeve f and the pinion. On actuation of the lever y to effect axial movement of the sleeve and pinion, the ball u is forced into the groove v in the collar until it is over the groove w, when the collar part r rides over the ball and holds it in the groove.
