Abstract: 1,233,760. Vending machine control. VENDO CO. 30 Dec., 1968 [3 Sept., 1968], No. 61638/68. Heading G4V. Control apparatus for a multi-dispensing mechanism (i.e. column) coin-freed, vending machine includes only one sold-out switch associated with each column, said switch being actuated momentarily on vending an article from the column to cancel the established credit and responding to depletion of articles from the column to prevent loss of established credit if a customer attempts to obtain an article from said column. In addition, a signal is applied through each sold-out switch to the control terminal of a triac supplying power to a coin acceptance unit, whereby on depletion of the articles in all of the columns, the control signals to the triac disappear, interrupting the power supply to the coin acceptance unit, so that further coins are rejected. A signal is supplied through each sold-out switch 46, 46a, 46b to the control terminal 68 of a triac 64 to energize an electromagnet 66 in a coin acceptance unit. Insertion of a coin actuates switch 78 momentarily to gate SCR88 and energizes credit solenoid 76 changing over contacts 72, 74. Contact 72 interrupts the control signals to triac 64 to de-energize the coin acceptance unit. The gating signal to SCR88 is maintained through contact 72, contacts 32, 32a, 32b, contact 74 and coin switch 78 to hold-on credit solenoid 76. Depression of an article selection button 58, 58a or 58b, energizes an associated vend solenoid 18, 18a or 18b through the sold-out switch 46, 46a or 46b and the vend solenoid is held-on through a contact 32, 32a or 32b and the associated soldout switch. The sold-out switch is operated momentarily at the end of the vending operation to interrupt the gating signal to SCR88 and restore the circuit to its original condition. If any column is sold out, the associated switch 46, 46a, 46b changes over so that the article selection button is no longer in circuit with the associated vend solenoid to prevent loss of credit if the button is depressed, and lamp 62, 62a or 62b lights up. If all three columns are sold-out, the triac 64 is de-energized and the coins are returned by the coin acceptance unit. Fig. 2 shows the mechanical dispenser for one column down which cans A roll. When solenoid 18 is energized, armature 20 retracts, stop 22 rotates clockwise to retain the second can while allowing gate 38 to rotate clockwise under the weight of the leading can and to dispense it. Gate 38 is returned anticlockwise to the position shown in dotted lines by spring 48, whereby arm 42 energizes sold-out switch 46 momentarily, thus breaking the holding circuit for the SCR88 to cancel the established credit. Vend solenoid 18 is de-energized, stop 22 retracted by a spring, and the next can engages with gate 38 to release switch 46. If no cans are left, sold-out switch 46 is energized permanently and light 62 also comes on permanently.

Abstract: 1,239,667. Hydraulic damper; lip seals. BRITISH RAILWAYS BOARD. 14 April, 1970 [18 April, 1969], No. 19982/69. Addition to 1,125,104. Headings F2B and F2S. The seal, bleed holes and automatic valves of the hydraulic damper of Specification 1,125,104 are modified. The piston 2 of the damper works in a tube 1; within a tube 6 providing communication from one side of the piston to the other via bleed holes 13 in the tube 1; within a valve-controlled reservoir tube 7. The seal comprises a multi-lip sealing ring 32 which is embraced by a spring ring 33 and has a flange 35 which is urged against a retaining flange 30 by a coil spring 34. The bleed holes 13, instead of being of constant cross-section as in the earlier patent, have a larger cross-section at the outside of tube wall 1 then the inside. This is stated to make the damping effect less temperature sensitive. Stacks 19, 24 of annular flexible valve elements are provided in the piston and at the entrance to the reservoir for overload relief. On compression strokes, the valve in the piston opens before the one in the base. The upper eye end of the damper is detachable. A square 38 machined on the pistonrod 3 engages a broached hole in the dust shield plate 39. The eye end is locked relative to the rod and plate by a tab washer.

Abstract: 1,250,500. Printers. HONEYWELL Inc. 12 Nov., 1968 [20 Nov., 1967], No. 53687/68. Heading G4H. In a printer of the kind in which a hammer is operated at the correct instant to cause printing from types on a continuously rotating type roll, the hammers are arranged in groups of two or more, the corresponding driving coils e.g. S<SP>1</SP>-1 and S<SP>1</SP>-67 being connected to common driving circuits 4D-1. In the form of Fig. 1 one of each group of two is in the left-hand set H1-H66 and the other is in the right-hand set H67- H132. The driving coils of the left-hand set are connected to line B-1 and those of the righthand set line B-2. These are energized alternately as each line of characters passes through the printing position, by switches SCR-1 and SCR-2 controlled by timing pulses. The characters in the right-hand section PR<SP>1</SP>-2 of the roll are displaced relative to those in the left-hand section PR<SP>1</SP>-1 so as to be later at the printing line PP. For each character, printing first takes place in the left-hand half, switch SCR-1 being operated by a pulse P-1, and the character is then printed in the right-hand half, switch SCR-2 then being energized by pulse P-2. The character selection pulses are applied to inputs CS-1, C2-2 &c. There may be more than two displaced sets of characters, the drivers then being connected in sets of more than two, enabled in succession. Instead of being arranged in two large groups each occupying half the print roll, the two relatively displaced sets of characters may be interspersed in twos (Fig. 2A, not shown) so that the first and third hammers are paired and the second and fourth and so on.

Abstract: 1,259,030. Automatic door closer. DORKEN & MANKEL KG. 29 Oct., 1969 [7 Nov., 1968], No. 53012/69. Heading E2M. An automatic door closer has a shaft 18 mounting cam 29 which, when the shaft is rotated by pivotal opening door movement, co-acts with roller follower 28 on slide 15 to move the slide. Spring 13 and hydraulic pistoncylinder unit 12 impose a clamped closing movement on the door via connecting rod 14. A second cam follower, 27, is mounted on the slide diametrically opposite to roller 28 with respect to shaft 18, and prevents the door "overtaking" the slide due to a closing force imposed on the door. When the door is closed roller 28 engages recess 30 at two points symmetrically disposed about an imaginary line joining the centres of shaft 18 and roller 28 thus enabling spring 13 to maintain the door closed.

Abstract: 1,266,676. Purification of 1,2-dichloroethane. KNAPSACK A.G. 7 April, 1970 [9 April, 1969], No. 16345/70. Heading C2C. 1,2-Dichloroethane recovered from the incomplete thermal cracking of 1,2-dichloroethane to vinyl chloride and contaminated with low boilers boiling below 83.7‹ C. and high boilers boiling above 83.7‹ C. is purified by reaction with gaseous chlorine in the presence of ferric chloride at 30-85‹ C. to convert low boilers to high boilers, and distillation of 1,2-dichloroethane from the high boilers. The process may be effected by (a) chlorinating contaminated 1,2- dichloroethane simultaneously with the chlorination of ethylene to form 1,2-dichloroethane, and distilling off the 1,2-dichloroethane, or (b) distilling the contaminated 1,2-dichloroethane in a low boiler distillation column, continuously removing a 1,2-dichloroethane-low boiler mixture from the head of the column, chlorinating the mixture, recycling the reaction mixture to the low boiler distillation column, and either (1) removing a 1,2-dichloroethane high boiler mixture from the base of the column and passing it to a high boiler distillation column, or (11) continuously removing 1,2-dichloroethane at a position below the column head and removing high boilers from the column base. A single column may serve as both a low boiler distillation column and a high boiler distillation column.

Abstract: 1288728 Data processing INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [16 April 1970] 27189/71 Heading G4A In a microprogram controlled data processing system having a store in which a portion having the highest order addresses provides storage for microprogram control words and the remaining portion having lower order addresses provides storage for data and program instructions, an address check boundary register stores data indicative of the total storage capacity and the address boundary between the two portions of the store and the microprogram control words are addressed by words selectively modified in accordance with the contents of the address check boundary register. The address check boundary register (ACB) is initialized to indicate total storage capacity, the address boundary, whether the store is servicing one or more than one processor, and whether the microprogram addresses are to be modified. Access to the store is always on a double word basis though data may be stored on a byte, half word (two bytes), or full word basis. The store is addressed by means of a register which is divided into three parts. The first part has eight bits, the first three determining byte, half word, or word selection respectively in a storage operation and the remaining five bits specifying one of sixty-four words. The second part provides eight bits for selecting one of 256 portions of the store (the address in the selected portion being specified by the first part) i.e. 16 K words, and the third part provides four bits giving 16 further combinations to give a total of 256 K words which may be addressed. The total store is then divided (according to requirements) between microprogram control words, and data and programs. Sequences of microprogram words are, wherever possible, maintained within the same portion of the store so that only the first part of the address register need be altered. In operation the address of a required word is supplied to a logic circuit which is described and which is connected to the ACB. The logic circuit also has inputs derived from the previously accessed control word and is operative to form an address for transfer to the addressing register in accordance with its various inputs, e.g. the part of the contents of the ACB indicating the boundary between the microprogram words, and the data and programs in the storage unit, and the previous microprogram control word inputs indicating that a microprogram word access is required. When the address has been formed it is then compared with the address boundary to determine whether the correct part of the store is being accessed, an error signal being generated where appropriate. The address register is provided with a back up register which contains the address of the previously executed control word, the address register containing the address of the current word, so that the back up register may be utilized during error check routines. Party bits may also be included in the contents of the ACB.
