Title: Electric Windscreen Wiper and Washer Units.
IPC: B60S1/48
Filed: 1967-11-23
Abstract: 1,187,137. Windscreen cleaning systems. GENERAL MOTORS CORP. 23 Nov., 1967 [25 Nov., 1966], No. 53311/67. Heading A4F. [Also in Division H2] A windscreen cleaning system comprises a first control circuit operable to energize intermittently an electric wiper motor, and having a timer device for controlling the period between the intermittent energizations of the motor, and a manually operable switch in series with the timer device for controlling energization of the first control circuit, and a further manually operated switch controlling energization of a second control circuit operatively connected with a windscreen washer unit and said wiper motor for energizing the washer unit and continuously energizing the wiper motor during operation of the washer unit. The timer device may be thermally actuated. In the system illustrated the wiper motor 10 is operable continuously at high speed or continuously or intermittently at low speed according to the manual setting of a switch 16. When the movable contact 44 of the switch 16 bridges bus bars 38, 40, 42 the motor 10 is continuously energized from a battery 18 via a closed switch 12, bimetallic element 22, contacts 20, and a coil 32, and current also flows through a coil 34 to cause the motor to run at a low speed. When the contact 44 bridges bus bars 38, 40, only the current through the coil 34 is reduced and the motor 10 runs continuously at high speed. When the contact 44 engages bus bars 46, 48 and 50 and a manual switch combined with a rheostat 28 is closed, a circuit is completed through the bimetallic element 22, contacts 20, a heater 26 for the bimetallic element 22, and the rheostat 28. The element 22 deflects on heating to open contacts 20, whilst the motor 10 continues to be energized until a switch 31, cam-operated by the motor, is opened at the end of a wiping cycle. On cooling of the element 22 for a period dependent upon the setting of the rheostat 28, the contacts 20 close so that a further wiping cycle commences. In the off position of the switch 16 a relay core 14, which holds the switch 12 closed, is de-energized, and the switch 12 is opened by a cam at the end of a wiping cycle to de-energize the motor 10. The motor 10 is also energized when a switch 56 is closed to operate a windscreen washer (not shown), a relay coil 58 being then energized to close contacts 60 to short circuit the bimetallic element 22.

Abstract: 1387984 Transistor oscillator circuits SIEMENSAG 26 Nov 1973 [21 Dec 1972] 54770/73 Heading H3T In an oscillator comprising a pair of complementary transistors T1, T2 connected in a pushpull circuit, their working points being adjusted by varying at least one resistance element in a voltage divider (Fig. 1, not shown), the resistance element takes the form of a further transistor T3 whose conduction is controlled by the output signal from the oscillator, its collector-emitter path being arranged between the base electrodes of the complementary transistors T1, T2, it being so connected that it is driven to present a progressively lower resistance as the amplitude of the output signal increases. In the embodiment, the oscillation frequency is determined by a quartz crystal Q shunted by series-connected capacitors C1, C2, C3: a detector circuit comprising diode D5 and transistor T4 is coupled to the common point of capacitors C2, C3, the output from transistor T4 providing the variable bias for transistor T3. A chain of diodes D1- D4 determines the bias on transistors T1, T2 before oscillations commence, or if crystal Q is removed. The output is taken from a potentiometer comprising resistors R5, R6, in which R5 may be replaced by a fixed resistor in combination with a negative temperature coefficient resistor to provide temperature compensation of the output level. The arrangement is such that transistors T1, T2 are biased in class A when oscillations start, but as the amplitude increases are progressively biased back in class B and C, so reducing power consumption.

Abstract: 1,152,072. Mattress making machines. SPUEHL A.G. 15 Dec., 1966 [12 July, 1966], No. 56155/66. Heading A4M. A mattress making machine includes means for receiving coil springs 25 individually from a spring making machine 21, assembling the springs 25 into a row between a pair of intermittently advanced, endless conveyer belts 29, and delivering the row to a machine (22) for joining the springs to form a mattress interior. A spring transfering arm 27, Figs. 1, 5, is pivoted on a shaft 52 for movement between a first position 26 in which it receives a spring 25 from an intermittently rotated, star conveyer 24 and a second position 27<SP>1</SP> in which it releases spring 25 between the spaced facing runs of the belts 29. The arm 27 has a U-shaped head 64 with sides 65 against which the spring ends are clamped by claws 71 each carried by a bell-crank 67 pivoted at 66. The bell-cranks 67 are pivoted to a clamping position against a spring bias 68 by engagement of their free ends with the piston head 69 of a pneumatic cylinder 62. The head 64 is carried on a spindle 56 which may be rotated through 180 degrees to ensure that the spring knots (72) will be positioned inwardly of the row to be assembled so that the knots will be disposed inwardly of the mattress sides. The rotation is effected by a pneumatic cylinder 59 having a piston rod 61 formed as a rack meshing with a pinion 57 on the end of the spindle 56. The belts are intermittently driven by a continuously rotated crank 37 which reciprocates a crank 35 acting through a one-way drive mechanism 34 to rotate the drive shaft 33 for the belts 29. A grab beam 85, Figs. 4, 10, is carried between a pair of laterally spaced plates 72 pivotally mounted at 78 on side supports 73 of a carriage 50 mounted on tracks 49 extending transversely of the conveyer belts 49. The beam 85 is guided for movement along L-shaped slots in the plates 77 and carries a plurality of grab arms 83 which are moved simultaneously between a first position, as in Fig. 10, in which each arm 83 picks up a spring 25 from between the belts 29 and a second position (Fig. 8) in which the row of springs picked up by the arms 83 is transferred to the machine (22) for joining the springs. Pneumatic cylinders 88 and 112 serve respectively to pivot the plates 77 and to move the grab beam 85 along the L-shaped slots in moving the grab beam between its first and second positions. Each grab arm 83 is provided at its free end with a hooked latch (139, Figs. 17-19) which is operated by a pneumatic cylinder (116) and piston (128) to engage and release a spring 25 with and from the grab arm 83.

Abstract: 1369453 FET storage cells RCA CORPORATION 3 Dec 1971 [14 Dec 1970] 56203/71 Heading H3T A F.E.T. T11, T12, T21 or T22 which stores a 0 or 1 by being set to one threshold state or the other has a circuit which sets it consecutively to one state and then the other before setting it to a selected state. To write, the bit lines B11 to B22 are first earthed and the appropriate word line W1 or W2 (normally earthed through Q12, Q22) is connected to a cycle generator 52 through Q11 or Q21. Successive positive and negative pulses are applied to the gates of T11, T12 (say) in times t 1  to t 4  (Fig. 4, not shown). Actual writing of a 1 in T11 is effected by switching B11, B12 to - V during the negative pulse of the next cycle from the generator (t 7 -t 8 ), so that low threshold (V TL , Fig. 1, not shown) to which T11 is set by the positive pulse in t 5 -t 6  time is maintained. Reading is by detecting the state of conduction of a F.E.T. when a signal having a value between the two thresholds is applied to its gate. The cycling prevents a progressive shift of a given threshold state in response to successive gate signals of the same polarity, which could for example change a F.E.T. from enhancement to depletion mode.
