Title: Method of and apparatus for covering shoe heels
IPC: A43D25/12
Filed: 1961-09-29
Abstract: 971,001. Covering heels. W. ULLRICHT. Sept. 29, 1961 [Oct. 6, 1960], No. 35011/61. Heading A3B. A method of covering a shoe heel 25 comprises the steps of forcing an adhesively coated heel together with a covering 26 therefor between a pair of spaced apart resilient applicators 12 which effect the covering of the back or rear of the heel, then passing the heel during the same feed movement through a folder arrangement which folds over edges 27, 28 of the covering 26 projecting at the seat and tip of the heel. In the construction shown the heel 25 is clamped to a slide 1 by a hydraulically actuated strap 3, the slide being reciprocated by a piston operated cable 6. A bridge 11 carries pivotably two conversely curved resilient applicators 12 which comprise operative resilient surfaces 22 in retainers 23 connected by a flexible web 13. The assembly is movable heightwise on the extension of the push rod 9. The distance between the open ends of applicators 12 may be adjusted by screws 19. The folder arrangement includes pairs of folder blocks 43 and fold formers 50, both pairs being mounted on parallel bars 41. The folder blocks 43 which pivot limitedly about axis 65 are carried by links 42 and rotary, spring loaded elements 61. The blocks are kept in co-operation by a spring 44. Fold formers 50 are pivotably mounted on axes 52 and are axially slidable against springs 51. The formers comprise a shaped fold block 54 with folding surfaces 55 and contact pressure surfaces 58. Presser shoes 72 mounted on spring loaded sensors 70 may be used to hold margins of the heel cover 26 against the lower surfaces of the applicators 12 and away from premature contact with the adhesive coated heel 25. In a modification (Figs. 8, 9, not shown) the retainers of the resilient applicators are pivoted about their ends on blocks which are adjustably mounted on a rotatable rod. As the operating surfaces move down a heel the applicators move apart against the action of a spring. In a further modification (Fig. 10, not shown) the applicators are pivoted about a point situated in the central region of the retainers.

Title: Improvements in or relating to pilot-operated fluid control valves
IPC: G05D7/01
Filed: 1960-10-13
Abstract: 916,312. Fluid-actuated valves. BRISTOL CO. Oct. 13, 1960 [Oct. 19, 1959], No. 35052/60. Class 135. A pilot operated non-bleed relay valve comprises a body 20 having three chambers 26, 27, 28 connected respectively via ports 17, 18, 19 to a pressure source, a power device and to atmosphere. Flow between chambers 26 and 27 is controlled by a valve member 40 acting through an 0-ring 49 and flow-between chambers 27 and 28 is controlled by a valve member 42 acting through an 0-ring 48. The valve members 40, 42 have telescoped tubular extensions 41, 46 respectively and the valve member 42 is fixed to a diaphragm 24 which with a cap 23 defines a control chamber 29 having an outlet orifice 33 which is controlled by a pivoted baffle 53. A third valve member 34 acting through an 0-ring 50 normally closes the bore of the valve member 40 and its stem 45 extends through the telescoped tubes 41, 46 and through the orifice 33. When the baffle 53 is away from the orifice 33 the members 34, 40, 42 are in the positions shown and the chambers 27 and 28 are interconnected. When the member 53 moves towards the orifice 33 it meets the stem 45 and moves the valve member 34 upwardly so that the supply chamber 26 is connected to the control chamber 29. The build-up of pressure in the chamber 29 when the member 53 closes the orifice 33 causes upward movement of the member 42 to close chamber 27 from chamber 28 and connect chambers 27 and 26. A notch in the stem 41 allows a continuous small flow from chamber 26 to 29 to compensate for any leakage losses. When the member 53 again moves away from the orifice 33 the pressure in the control chamber 29 falls and allows the return of the valve members 34, 40, 42 to their initial positions. Specification 797,115 is referred to.

Abstract: 1,056,503. Incremental tape drive. POTTER INSTRUMENT CO. Aug. 17, 1965 [Sept. 14, 1964], No.35168/65. Heading G5R. In an incremental drive arrangement-for an information storage magnetic tape 14, the tape is moved forward by one step when receipt of a start signal accelerates the capstan 13 up to a predetermined speed at which it remains until the occurrence of a stop signal. The capstan is accelerated up to the required speed by a servo speed control system 11 when flip-flop 29 is triggered to its " 1 " state by a differentiated start signal and decelerated to a stop when the flip-flop is triggered to its " 0 " state by a stop signal applied via " OR " circuit 43. During recording the stop signal is generated in photo-cell 19, which co-operates with lamp 21 and an apertured tone wheel 17 coupled to the capstan, and is applied via Schmidt trigger 39, differentiator 41 and gate 33 to " OR " circuit 43. During play back the stop pulse is generated by detector 47 when a played back recorded clock pulse reaches a peak value and is applied via gate 35 to the OR gate 43. The gates 33, 35 are controlled by the output signals from flip-flop 31 which is switched to its " 0 "state for recording and to its " 1 " state during playback. In a second arrangement, Fig. 3 (not shown), the capstan shaft is provided with clutch means for coupling to a continuously rotating motor and with brake means, both sets of means being controlled by the output of a flip-flop circuit having its input circuit connected in the same manner to flip-flop 29.

Fig. 3 shows the nth bit stage of a parallel ALU capable of binary addition, AND, OR and EXCL-OR operations. The stage receives signals at 70, 110 to select the operation, operand bits A n , B n  carry outputs C n-1 , C n-2 , C n-3  from the three next lower order stages and A n-1 , VB n-1 , A n-2 , VB n-2  from the two next lower order stages, and produces a result bit R n , carry bit C n , parity bit PF n , and A n VB n . Circuit 18 produces the AND and OR of A n , B n , one being selected at 24 to form PF n . For addition, carry generatcr 20 and sum generator 22 are used as shown, their outputs being EXCL-ORed at 36 to feed R n . For OR, an AND gate 116 passes the output of OR 62 to R n . For AND, an AND gate 118 fcrms A n  AND B n  and passes it to R n . For EXCL-OR, the outputs of circuit 18 are passed to AND 104 in sum generator 22, using inverter 94, the upper input of OR 102 and the lower input of OR 106, the output of AND 104 being passed to R n . Checking logic forms the EXCL- OR of the parity of operand A and the inverse of the parity of operand B and EXCL-ORs the result with either the EXCL-OR of the PF bits (in the case of AND or OR) or the EXCL-OR of the carries C (in the case of add). The result is compared (EXCL-ORed) with the inverse of the EXCL-OR of the result bits R, a 1 indicating error. As modifications, the operand bits A n , B n  could be applied directly to 20, 22 or 24, or not applied directly to 26<SP>1</SP> (the output of 18 being used instead).
