Patent GB-1231209-A (GB)
IPC: G06F7/50

Abstract: 1,231,209. Digital electric adder. WHITWELL ELECTRONIC DEVELOPMENTS Ltd. 5 Nov., 1968 [7 Nov., 1967], No. 50542/67. Heading G4A. Adder for two decimal numbers has means for adding one to each decade of an input number if a carry is supplied from the immediately preceding decade, has a ten-condition switch means, corresponding to digits 0 to 9, obtaining the least significant digit of the sum of each input digit (after the addition of a carry) and each digit to be added, means to generate a carry signal for each succeeding decade and means to generate a carry signal for the next succeeding decade but one when a carry signal is generated for the immediately succeeding decade and the input digit is 9. An adder shown in Fig. 5 has an input digit supplied on one of the inputs indicated 0-9 to one input of one of AND gates 11 and one of AND gates 12. A NO CARRY signal enables gates 11 to pass the input digit signal unaltered. A CARRY signal enables gates 12 and causes shift of the input digit signal to another line causing addition of one to the input signal. The other signal is represented by the position of contacts 41. As shown they represent 0 and movement to the right to successive columns of terminals represents successive increments of "1". As can be seen a signal on one of the input lines passes along a diagonal line to emerge via a contact 41 on an input line representing the least significant digit of the sum. A further five contacts 43 are moved in synchronism with contacts 41 to determine the carry. Carries occur when either digits are 5, 6, 7, 8, 9 and the lower line of the matrix provides a path supplying a signal to inverting amplifiers 46, 47 when this occurs. It can be seen that the other rows cover all other possibilities. In the event that a carry is produced and the input digit is 9 a further carry to the next stage must be produced. This step is performed by the circuitry shown in Fig. 7, where the boxes 51-56 each represent the set of AND gates 11, 12, shown in Fig. 5. When a carry occurs from one stage and when the next stage produces a jump carry signal indicating that it has increased from 9 to 0 then an AND gate 50 passes a carry to the next following decade. A circuit is given for addition using a 2 out of 5 code (Figs. 8 and 9, not shown). A subtractor (Fig. 14) operates in a similar fashion with borrows causing reduction of the input digit by one, the borrows being produced by an arrangement similar to that of Fig. 5. In this case a jump borrow is required when an input digit is reduced from zero to nine.

Abstract: 1290082 Sealing ceramics to metal PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 July 1970 [9 July 1969] 32718/70 Heading B3V [Also in Divisions C1 and H5] A method of shaping a hollow article of a heat-softenable material, such as quartz, glass or a ceramic material, which is a poor electrical conductor at least at room temperature, comprises initiating an electric gas discharge and maintaining the discharge within an open end portion of the article by means of a high-frequency inductor field, the intensity and duration of which are sufficient to ensure that the material of the end portion is completely heated up to above its softening point, whereafter the article is shaped by deforming the softened end portion. As shown, for sealing a metal member 30, such as a filament 31 and molybdenum supply conductors 32, 33, into a quartz lamp envelope 1 with main wall 2 and exhaust tube 3, a needle 6 with apertures 10 is inserted through tube 3, which is in a holder 4, and is supplied with argon or other gas from reservoir 8 through valve 9 and duct 7. The holder 4 is connected to a mechanism 5 for vertical movement and when the gas is flowing, the holder is moved up to the position of the lamp 1 in dotted lines where the upper part is enclosed in the coil 25 from generator 23. At the same time, an ignition pin 14, connected to a conveyer 13 and wire 12 to an ignition device 11, is moved to the dotted line position and the device 11 operated by a switch 17 in the circuit of the device 11. The operation of switch 17 also activates generator 23 and as soon as sufficient current flows through coil 25 to maintain the gas discharge, a time switch 24 is switched on for, for example, 5 seconds or such time as will cause the wall 2 to become incandescent and the winding 26 operates a switch 22 to switch off the ignition device 11. The heated lamp 1 is then lowered till the top wall is between pinch blocks 27, 28 and the member 30, held by a clamp 36, is lowered therebetween and the blocks 27, 28 moved together to form a flat pinch. Nitrogen or other inert gas may be provided during the pinch through apertures 37 in the clamp 36. Specification 1,127,426 is referred to.

Abstract: 1296050 Pipe coupling ENTREPRISE DE RECHERCHES ET D'ACTIVITIES PETROLIERES ELF 19 Dec 1969 [31 Dec 1968] 61981/69 Heading F2S A pipe joint comprises a spigot 1 and socket 7, the spigot being freely insertable into the socket until it abuts a conical portion 5. A resilient sealing ring 8 is housed in the socket 7 and may be axially compressed by an annulus 9 connected via pins 21 to member 10, which is in turn supported at pivots 11 by two rods 12. One rod passes behind the joint and the other in front of the joint and they are each pivotably connected at one end to a link 14 and at the other end to a jack 18. The link and the jack are pivotably connected to diametrically opposite positions on the socket. Actuation of the jack causes member 10 and annulus 9 to compress the seal so that it expands radially to grip the spigot. The jack may be double acting to facilitate quick release of the joint, or the link 14 may be severed. In any case the joint may be released by a strong pull on the spigot. The relative sizes of spigot and socket are such that a considerable degree of misalignment or defects in roundness or coaxiality may be accommodated. In an alternative arrangement (Fig. 2, not shown) the seal 8 is replaced by two seals (8a), (8b) which are independent and are axially separated by a ring (23) having radial holes. The presence of fluid in said radial holes may be detected via a bore in the socket adjacent the holes.

Abstract: 1355514 Door operating mechanism J A FAWDRY 17 July 1972 [17 April 1971] 9727/71 Heading E2M A door operating mechanism employs a screw and nut mechanism in which a nut is rotated by an electric motor and displaces a lead screw which is pivotally linked to a door attachment member. In the arrangement shown garage doors 2, 3 are connected to lead screw 8 by links 5 pivoted at 4 to door attachment members 3 and at 7 to a cross arm 6. A pulley 9 having an internally threaded portion 9A constitutes the nut and is connected to the pulley 16 of an electric motor 14 by a transmission belt 17. Plates 10 and 11 attached to a roof joist 12 prevent axial movement of the nut and provide support for the motor. The screw is prevented from rotating in the example shown by the link mechanism 5, 6; alternatively a projection on plates 10, 11 could engage a longitudinal groove in the screw. Elements 20, 21 are adjustably mounted on the screw and actuate limit switches 18, 19. The operating switch for the motor may be of various types: a manually operable key switch mounted on the door, a pressure or photo-electric switch operated by the vehicle, or a switch detecting a sound, light or magnetic signal transmitted by vehicle or driver. The edges of the doors may incorporate safety switches to prevent the doors closing on persons or objects, additionally the hinge pins 4 may be of soft metal so as to shear in the event of obstruction.  The mechanism may be employed in single hinged doors or in single doors of the 'up and over' type by connecting the lead screw to the upper edge of the door by a single pivoted link.
