Patent GB-1347888-A (GB)
Title: Fixed word stores
IPC: G11C17/02
Filed: 1971-09-16
Abstract: 1347888 Read only memory SIEMENS AG 16 Sept 1971 [30 Sept 1970] 43167/71 Heading G4A A read only memory comprises an insulating member carrying intersecting row and column lines which are electrically coupled at their intersections by coupling elements selectively provided on a carrier having guide edges and which may be inserted in a direction parallel to the insulating member along guide rails, the guide rails and guide edges being formed with recesses and elevations so that the carrier is restrained from moving perpendicularly towards the insulating member during insertion but is so moved by spring pressure when fully inserted. As described the carrier 13 has coupling elements 11 which may be ferrite, attached to it, e.g. by an adhesive, and is inserted by means of slide 19 which may be provided with a handle (not shown) and which engages the carrier by means of springs 22 and recesses 16. When the carrier 13 is fully inserted the recesses and elevations 29 and 30 of the guide rails match those on its guide edges 14 enabling it to move perpendicularly towards the insulating member. As the slide is pressed further home against the action of a spring which engages the carrier the springs 22 ride up the walls 17 of the recesses 16 and move the carrier 13 perpendicularly towards the insulating member. The slide has latch elements which engage similar elements fixed with respect to the insulating member and retain the slide and hence the carrier in the fully inserted position. The procedure is reversed when the carrier is removed, the carrier being first moved perpendicularly away from the insulating member and then parallel to that member as it is withdrawn.

Patent GB-438007-A (GB)
Abstract: 438,007. Thermal switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 22, 1935, No. 14946. Convention date, May 22, 1934. [Class 38 (v)] A thermal switch comprises a bi-metallic strip 13 fixed at 14 and engaged at its free end in a bearing 25 in one limb of a U-shaped spring 24, the other limb of which is pivoted on an adjustable screw 27. A rigid contact arm 30 is loosely mounted on the base of the spring 24 by means of lugs 31 which pass through slots in the spring. A spring 35 on a pin 36 biasses the arm 30 towards the spring 24. The contact arm is formed on its under side with two struck up transverse bearing surfaces 38 and two longitudinal bearings 40. When the spring 24 is snapped over by the bimetallic strip to move the contact arm between two sets of fixed contacts 43, 44, the bearings 40 allow the bridging contacts 41, 42 to accommodate themselves to the fixed contacts, while the arm pivots on one or other of the transverse bearings 38 while the lost motion between the arm 30 and spring 24 is being taken up, subsequently resulting in a sharper snap-action. Temperature setting is effected by movement of a screw 15. Specifications 280,323, [Class 38 (v)], and 402,243 are referred to.

The headrest 11 is carried by a U-shaped stirrup 16 pivoted on pins 13 engaged through the free ends of the stirrup 16 and through brackets 14 secured to the upper cross piece of an inverted U-shaped seat back frame 1. The apertures 15 in the stirrup 16 to receive the pins 13 each includes an extension with flats 15a which are engageable by flats 13a on the pin 13 to releasably lock the stirrup in the raised position. The headrest 11 includes a U-frame 18 which is secured to a pair of bushes 37 rotatable on the cross-piece 16a of the stirrup 16. A locking pin 20 is carried by the frame 18 and is spring biased into engagement with one of a plurality of notches 22 in the periphery of a wheel 23 rigid with the stirrup cross-piece 16a whereby the inclination of the headrest 11 may be adjusted and locked. The pin 20 is displacable from the notches 22 by operation of a hand knob 28. The auxiliary cushion 10 is connected by straps 30, 31 to the bushes 37 and by resilient straps 32 to a fixed part 3 of the seat frame. When the stirrup 16 is swung upwardly to raise the headrest 11, the cushion 10 is drawn into the created space against the bias of the straps 32. The back rest as a whole is pivotable about a horizontal axis 2.

Title: A device for issuing an electric signal when supplied with an electric impulse within each of two or more intervals
IPC: E05B49/02
Filed: 1965-10-19
Abstract: 1,128,923. Electric selective signalling. H. B. BERGKVIST. 19 Oct., 1965 [28 Oct., 1964], No. 44170/65. Heading G4H. A cam assembly 11 has a plurality of camming surfaces 16, 17 positioned to close contacts 23, 25, and 35, 36, at predetermined times during the rotation of the cam assembly 11 to prepare the path to an electric signal issuing device which is operated if electric impulses are passed to the contact switches at the correct times, an incorrectly timed impulse energizing a relay 28 to prevent operation of the device. In the form shown, for controlling a door, a dial 2 and pushbutton switch 1 are positioned outside the door. On depression of the switch 1, solenoid 33 is energized to raise a member 8 and so close contacts 9, 10 to energize the motor 5 which rotates cam assembly 11 and pointer 3 on the dial. When notch 16 on the cam engages roller 21 holding relay 30 is energized via contacts 23, 24 if the switch 1 is depressed at this time, to close contacts 31. If the switch 1 is pressed when the pointer 3 reaches the position 9, that is while cam surface 17 is holding contacts 23, 25 and 35, 36 closed, an impulse is passed via contacts 31 and closed contacts 32 of a relay 28 to energize the door operating mechanism 29. If the switch 1 is pressed at any other time, contact 23 is in engagement with contact 24 so that the impulse is applied to energize the relay 28 and open contacts 32 which are then held open for the complete cycle.

Title: Addition subtraction device utilizing memory means
IPC: G06F7/495
Filed: 1972-09-26
Abstract: 1365783 Digital arithmetic units CASIO COMPUTER CO Ltd 26 Sept 1972 [29 Sept 1971] 44353/72 Heading G4A An adding/subtracting circuit includes a shift register 11 fed by an adding/subtracting unit 12. Data words are stored at successive addresses in the register, separated by stop codes, and the output of the register 11 is fed back to the input of the adding/subtracting unit 12. When a stop code is being fed back the adding subtracting unit 12 is switched from decimal to hexadecimal operation. When, as a result of a subtraction, a complement result is formed the associated positive stop code S is converted to a complement stop code S<SP>1</SP>. In operation, suppose that a number is to be written in the third address in register 11. The address number 3 is set in counter 24. The first address in the register is indicated by a code F. When this reaches stage Do of the register it is detected by unit 19 causing bi-stable 21 to be set and counter 24 to be decremented each time a stop code S or S<SP>1</SP> is detected. When the third stop code reaches Do counter 24 will be set to zero, so setting bi-stable 25 and causing the input number in buffer 16 to be added in decimal fashion to the number (if any) in the third address, now being fed back to adding/subtracting unit 12 via gate 13. The result is stored in the third address, and when the next stop code is detected at Do bi-stable 25 is reset, terminating the writing operation and switching unit 12 back to hexadecimal operation. Operation in the case of subtraction is generally similar, unit 12 being supplied with a subtract command. However if the result of the subtraction is a complement (e.g. 479-500 gives the result - 21 which will appear in register 11 as the complement 999 ... 979) a borrow signal will occur. When the next stop code is fed back, unit 12 will be set to hexadecimal operation as before and the positive stop code, assumed to be the 4-bit signal 1111, will be changed by the borrow signal to a complement stop code S<SP>1</SP> = 1110. Should such a large positive number be added to a complement number that a positive number results, the following complement stop code S<SP>1</SP> is automatically transformed to the positive form S by the hexadecimal addition of the carry to S<SP>1</SP>. During read out from a selected address the data is fed back via gates 18 and 17 to buffer 16, as well as being fed back to unit 12. The read out command also enables gate 28 so that unit 29 can detect the complement code should the data be a complement. When the number at this address is displayed it may be accompanied by an indication, generated by unit 29, that it is a complement. Alternatively detection of the complement code may cause the number read out to be transformed to, and displayed as, the negative number (e.g. as -21) by means not described.
