Title: Improvements relating to data handling apparatus
Inventor: BILLIN JAMES JOHN
IPC: G11C19/06
Filed: 1968-02-17
Abstract: 1,261,721. Magnetic storage arrangements; telephone exchange systems. EMI Ltd. 17 Feb., 1969 [17 Feb., 1968], No. 7874/68. Headings H3B and H4K. [Also in Division G4] Data handling apparatus includes plurality of queue means, each including a series of registers with an index storage element for each register, indicating occupancy, whereby a group of digits entered into.a first register of the series is shifted along the series to the latest unoccupied register, there -being .means for combining data from the last -register of each of the queue means such as to give data from a particular queue means priority over data from others of the queue means. One queue means is shown in Fig. 1, in which four bits, entered on switches S1 ... S4 are shifted to the rightmost unoccupied column of multi-aperture cores 1a ... 1d, 2a ... 2d, 3a ... 3d under control of respective index cores 1e, 2e, 3e. The cores are initially blocked, being set to indicate "1", an index core being set to indicate "occupied". Transistors T1, T2 are rendered conducting alternately by clocksignals A, B (if -there are more than columns, alternate transistors receive A and the rest B), when, provided both index cores linked therewith (1e and 2e in the case of T1) are not in the same state (set or blocked), a corresponding SCR (or four layer diode) D1, D2 conducts, in response to interrogating A.C. applied to terminal 5, to apply blocking current to a corresponding column lead L1, L2 to shift the data (and set state of index core) to the next column, with the aid of priming current applied via resistor R10. This priming current may be switched in synchronism with the blocking current to provide an inhibiting bias to prevent reverse shift. Fig. 2 shows the last index cores Ae, Be of two respective queue means, and the first three index cores 1e, 2e, 3e of another queue means fed from them, with B having priority over A since, while data can be transferred from B in response to the first clock signal A after the clock signal B in response to which core le is blocked, data can only be transferred from A in response to the next clock signal B following the clock signal B in response to which core 1e is blocked. Output from the last column can be parallel or serial by bit. An application is as a key sender in intercontinental telephone dialling. The bit-coded decimal digits are transferred from the last column to a ten stage queue so that each decimal digit is provided in this queue in the form of n pulses where n is the value of the digit, the pulses being consecutive (except in the case of digit 9 where however the only gap is closed up by using a lower output speed than the shifting speed in the queue).

Title: Memory with redundancy
IPC: G06F12/16
Filed: 1969-02-14
Abstract: 1,260,914. Data storage. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1969 [19 Feb., 1968], No. 8224/69. Heading G4C. Defective word locations in a group organized memory are effectively replaced by redundant word locations under control of an indicator memory holding position-within-group address parts. The address of a word to be accessed has a group part and a word part. The group parts is decoded to half-select a group of stored words and full-select an indicator word respective to the group. The word part is compared with the word parts of the addresses of defective words in the half-selected group, these parts being contained in the indicator word. If there is no match, the word part of the applied address is decoded to complete the selection of a word in the half-selected group, whereas if there is a match selection is completed of a redundant word in the group (to replace the defective word). The position of the defective-word address word part giving match, in the indicator word, indicates implicitly which of a plurality of redundant words in the group is to be selected, or the indicator word may also contain n bits for this purpose associated with each defective-word address word part, where there are 2<SP>n</SP> redundant words per group. Sense amplifiers and an output register are shared between all the groups of words and all the indicator words. The indicator words could be in erasable (non-destructive readout) or in read-only storage. The groups could alternatively consist of even and odd addresses respectively.

Title: Improvements in or relating to control mechanism for a carburettor throttle valve for use with an internal combustion engine driving a vehicle provided with an automatic change speed gear box
Inventor: MCCONNELL WILLIAM ROGER
IPC: F02D29/02
Filed: 1963-03-01
Abstract: 1,080,593. Change-speed control. SMITHS INDUSTRIES Ltd. Feb. 24, 1964 [March 1, 1963], No. 8394/63. Addition to 950,217. Heading F2D. In a vehicle having an automatic changespeed gear and a carburetter-throttle valve which is automatically actuated during ratio shift, the throttle valve is closed to a greater extent during upshift than during downshift. As shown, the throttle valve is a butterfly valve having a spindle 11 fast with an arm 14 carrying a pin 17 which is urged by a spring 24 against a lever 19 which is linked to the usual accelerator pedal. The arm 14 is connected by a link 16 to a lever 40 rotatable on a spindle 37. The automatic change-speed gear is provided with a shaft 25 which is automatically rotated when conditions arise necessitating a shift, the shaft 25 carrying a cam 26 engaged by a follower roller mounted, with some play permitted by a slot, on an arm 31 pivoted at 32 and fast with an arm 33 which is connected by a link 35 to a three-armed lever 36, 39, 41 pivoted on the spindle 37. Normally the follower roller is in a recess of the cam 26 and arm 41 is clear of the lever 40, permitting actuation of the butterfly valve by the accelerator 22 throughout its full range. When upshift is to occur, the shaft 25 is rotated anticlockwise, the follower roller moving to the left-hand end of the slot and riding out of the cam recess, thereby imparting sufficient anticlockwise movement to the three armed lever for the arm 41 to engage the lever 40 and move it clockwise, thus moving the butterfly valve towards its closed position, the spring 24 being tensioned to permit this movement with the accelerator pedal stationary. During downshift the cam 26 is rotated clockwise so that the follower roller is brought to the right-hand end of its slot so that a smaller closing movement is imparted to the butterfly valve than for upshift.

Abstract: 875,331. Orientating cans. GREEN & LAXTON Ltd. Jan. 22, 1960 [March 12, 1959], No. 8572/59. Class 78 (1). [Also in Group XXII] An arrangement for locating the longitudinal seams of cylindrical cans to be soldered in an automatic can-soldering machine comprises means to deliver cans one at a time on to a pair of parallel rollers rotatable to rotate a can thereon, means to stop the rotation of a can on the rollers when the seam is in its lowermost position, means to stop the rotation of the rollers after the rotation of the can has stopped and means for moving the can from the rollers. The can rotating station is provided at the feeding end of a slideway, e.g. a pair of parallel rails, at points along which are arranged a flux bath and a solder bath, and comprises a housing 11 carrying a pair of rollers 12, 13 in line with the slideway. The rollers are rotated by chain wheels 14, 15 and a chain wheel 16 connected by a clutch 18 to a main shaft. Cans are fed on to the rollers 12, 13 down an inclined shoot 19, 20 adjustable in width, having a block 21 with pins 22, 23 held by plate 26 on a lever 27 with a cam follower 28 in the position shown with pin 22 projecting into the shoot and spring-urged in the direction of arrow 24 to a position in which the pin 23 projects into the shoot, one complete movement of the block 21 from the position shown to its other position and back again effecting the release of one can. A feeler arm 29 above the rollers 12, 13, and carrying a spring-pressed blade 31 is movable back and forth by a lever 35 having a cam follower 37 and has a cut front portion 33 so that when it is moved forwards its leading end is lowered. A timing shaft 38, driven by the main shaft, carries three cams 39, 40, 41 for a follower 42 coupled to the clutch 18, the follower 37 on the arm 35 and follower 28 on arm 27. Operation.-Cans are fed into the shoot with their axes parallel to rollers 12, 13 to be released one at a time by the block 21 to roll on to the rollers. At this point the clutch 18 is engaged to rotate the rollers and thus the can and the feeler 29 is moved forward and the feeler 31 is lowered into contact with the can. When the raised seam engages the feeler its rotation is stopped and after the cam is stopped the clutch is disengaged to stop the rollers. Then the arm 29 is withdrawn and the can is moved axially to the flux and solder baths by a projection carried by a conveyer chain beneath the slideway. A second conveyer chain ahead of the main conveyer may be provided to move each can from the rollers 12, 13 and a pair of arms may be swung adjacent the front and rear of the can on the rollers to prevent it moving or tipping.
