Title: Captive screw fasteners for panels, aircraft cowlings, covers, doors and the like
Inventor: READ MARK AMBROSE
IPC: F16B5/02
Filed: 1952-12-22
Abstract: 761,655. Screw fasteners; anchor bolts. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 23, 1954 [Dec. 22, 1952], No. 32418/52. Classes 44 and 89 (1). In a captive screw-fastener in which a screw 10 has a part 9a of its shank adjacent its head plain and of reduced diameter, the screw being carried by a structural-unit 2 and adapted to engage a screw-threaded hole in a second structural unit 1 to secure such units together, the screw-threaded part a of the screw, whilst the screw is being retracted to disengage from the screw-threaded hole in the unit 1, comes into engagement with a screw-threaded hole in the unit 2, the head of the screw being located in a housing 12 which limits retraction movement of the screw, whereby it is prevented from being retracted out of engagement with the unit 2. The screw-threaded hole in unit 2 is in a conical washer 8, which is slidable in the housing 12. The housing is secured to the unit 2 so that the outer face of the washer can engage a correspondingly-shaped cavity 7 in the unit 2. The washer has projections 14 which engage slots 15 in the housing to guide its movement and it is urged into the cavity 7 by a helical spring 16 acting on the projections 14 and lugs 17 in the housing. This screw 10 has a countersunk head engaging the interior of the washer 8 and it is rotated into engagement with unit 1 by a screwdriver &c. engaging a recess 11 in the shank 9. When the screw is fully engaged with the hole in the unit 1, it is no longer in screwed engagement with the washer 8 since the part 9a of its shank adjacent the head is then in the hole in the washer. When the screw is rotated to release it from the unit 1, the screwed part of the shank engages the threaded hole in the washer 8, the washer moving downwardly against the spring, if necessary, to allow this and when the end of its shank is flush with the face of the unit 2, the unit 1 is released. Free rotation of the screw is prevented by inwardly-directed tongues 19 in the housing wall. In a modification, the washer is cylindrical and is rigidly fixed between the housing and the unit 2. The screw is cheese-headed and bears against the underside of the washer when the threaded portion of its shank is fully engaged with the unit 1 and free from the threaded hole in the washer. The recess 11 may have a spring- pressed plate in it to conceal it when it is not in use.

Title: Improvements in or relating to circular knitting machines
Inventor: GILCHRIST REGINALD SELBY
IPC: D04B9/18
Filed: 1961-10-12
Abstract: 955,038. Knitting-machines. KLINGER MANUFACTURING CO. Ltd. Jan. 14,1963 [Oct. 12, 1961; Dec. 4,1961], Nos. 32538/61 and 43343/61. Heading D1C. A circular machine has a reinforcing or splicing yarn introduced over part courses during continuous rotary knitting and has means whereby the float portion extending between the point of withdrawal and the point of introduction of the yarn in each course is extended and drawn by a suction nozzle into a bight outside the needle circle whereafter it is offered to the needles and laid in with the loops of the succeeding course. Prior to the nozzle drawing the bight of yarn, the amount of yarn to be drawn into the bight is measured and formed into a loop. To this end the splicing yarn feeder 21 is introduced and withdrawn during each course by mechanism comprising a slide bar 28 carrying a lever 27 actuated by a cam 26 which is revolved with the needle cylinder. The extent of introduction of the yarn guide 21 is controlled by a further cam 29 determining the movement of the slide bar 28. When the guide is withdrawn from operation, after feeding its reinforcing yarn for a part course, a loop is formed in it between the feeder and the supply. A slide block 53 guided between two guides 50, 51 has an eye 54 through which the yarn passes to the feeder. To form the loop after the feeder has been withdrawn the block is raised by a pneumatically operated piston and cylinder device to extend the yarn in an upwardly directed loop. A series of rods 64 of varying length mounted on a ring rotatable by a pawl and ratchet determine the extent to which the block is raised and thereby the length of the loop of yarn drawn. The position of the rods 64 is determined by a cam segment on a wheel which also controls the movement of the cam 29 whereby the length of the loop of yarn is determined relative to the period the yarn feeder is active. After the block 53 has drawn the yarn into an extended loop the block 53 is lowered and a suction nozzle 39, positioned after the feeder 21 and outside the needle circle, draws the yarn so that the loop is drawn in a bight which extends within the nozzle as shown at L in Fig. 3. The needle cylinder having rotated the yarn feeder 21 is again introduced to feed the yarn to the selected needles whereafter the needles are again raised and the bight of yarn extending from the nozzle is taken by them so as to be laid in with the loops of that course. Instead of the block 53 a pivoted yarn guide 104 which draws a loop of yarn and which is controlled mechanically or electro-magnetically may be provided. A cam 111 serves to determine the extent of movement of the guide 104. Specification 947,037 is referred to.

Title: Machine for making filter elements
IPC: B31D5/00
Filed: 1946-11-04
Abstract: 622,844. Making fitter elements. ALLAM, P. S. (Fram Corporation). Nov. 4, 1946, No. 32688. [Class 31 (i)] [Also in Group XVI] A machine for making filter elements, such as described in Specification 608,531, [Group I], is constructed so that the units for advancing a web of material, for cutting or stamping the same to form the filter elements, and for assembling a series of cut elements, are individually supported in a frame formed of uprights 11, 12, 13, horizontal stringers 14, 15 and cross stringers, not shown. The web is fed from a roll 18 by path 21 to a pair of continuously rotating feed rollers 31, 35, Fig. 4, and then via path 22 around the roll 18 to a looping device 24, and via path 25 to a pair of rollers 40, 47, the roller 47 having adjustable segments for advancing the web intermittently to cutting dies 74, 75, shaped to cut sections 77, Fig. 2, having a form corresponding to the filter elements of the above Specification. From the dies the elements are delivered by the aid of air blasts to an assembling disc 111 mounted on a fixed spindle 115. The disc 111 is fitted with four rotary members 135, in each of which is mounted a pin 139 for receiving a series of filter elements, each pin has a flange 140, Figs. 2 and 9, formed with an aperture 141 adapted to receive a driving-pin 138 on a rotary member 135 fitted with a gear 142 engaging a central gear 143 adapted to be driven intermittently by a grooved cam which engages projections 145 depending from the gear 143. The gear 112 on disc 111 is driven by a one-revolution clutch which causes the disc to rotate for a quarter of a revolution, and the disc 111 stops when the pins 139 reach assembly position. The disc 135 is then rotated intermittently through angles of 60 degrees so as to receive a filter element at each position and thus form a filter pad with each element in proper assembled position. The feed rollers 35, 47 are mounted in spring-pressed pivoted arms 32, 41 which can be displaced by cams 158, 159 to permit of threading the web, and the web is controlled by a spring-pressed side guide pin 92, which maintains one edge in contact with an abutment 95. The mechanism is driven by a motor E which drives a fly-wheel 86 on a central drive shaft 83 from which the assembly and feed units are driven by chain gears. Specifications 622,902, [Group XVI], and 622,903, which are divided from the present application, are referred to.

Title: Apparatus for sorting articles carried on a conveyor belt
IPC: B65G47/50
Filed: 1961-09-12
Abstract: 946,616. Endless conveyers. TELEPHONE & ELECTRICAL INDUSTRIES Ltd. Sept. 12, 1961 [Feb. 13, 1961], No. 32702/61. Heading B8A. An apparatus for sorting parcels comprises a conveyer belt (not shown) tilted sideways so that the parcels slide at one side on a wall of the conveyer trough which is fitted with drop-panels which may be opened to allow parcels to slide into receptacles or on to secondary conveyer belts. When a parcel is started on the belt the selected destination is registered in a binary code in a Translator and Meter Selector relay set 2 by depressing a key on a Control Unit keyboard 1, and fed to a transfer circuit 4, with a check on accuracy by a code check 6 which checks whether the code contains an odd or even number of binary digits. When the parcel passes a Gate Unit 5 located a short distance from the loading station a light beam to a photo-cell is interrupted and a pulse passed to the Transfer Circuit 4 and the Transfer and Meter Selector 2. When the parcel clears the Gate Unit 5 the Translator and Meter Selector relay set 2 are re-set. The code in the Transfer Circuit is fed to a Shift Register 7 and a meter which gives the total number of parcels sorted advances one unit while a meter recording the total to the particular destination also advances one unit. The code now progresses through the Shift Register 7 under the control of a Belt Pulse Source 9 which produces a pulse every few inches of belt travel and triggers a Clock 10 which generates a series of pulses one of which is routed to the Shift Register 7 through a Pulse Distributer 11. The code proceeds a step at a time through the Shift Register and is presented to each Diverter in turn at a time when the parcel projects a short distance beyond the leading edge of the appropriate diverter. When the code is presented to the correct Diverter Controller a code gate opens and the appropriate diverter magnet is operated to open the diverter allowing the parcel to slide into a receptacle or on to a secondary conveyer belt. The code is removed from the Shift Register 7 and after a brief delay the diverter closes. The apparatus may employ bi-stable devices such as electron tubes, semi-conductors, cold cathode tubes, square-loop magnetic cores or electromagnetic devices solely or in combination.

Abstract: 1,172,067. Fuel supply systems; spray carburetters. AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT. July 9, 1968 [Sept. 13, 1967], No. 32739/68. Heading F1B. In a fuel supply system for an I. C. engine, a fuel injection pump a is supplied from a tank 5 by two feed pumps 1 and 2 connected in series and adapted to be driven by the engine. The pump 1 delivers fuel at a low pressure to the upper part of a chamber 9 providing a head of fuel above the chamber outlet 14 communicating with the inlet of the pump 2. Pump 2 delivers excess fuel at a high pressure, e.g. 1 Kg/cm<2>, to the injection pump a. The volume of fuel contained in the chamber 9 above the outlet 14 is at least equal to the volume of fuel delivered by the injection pump a during priming of the pump 1. Excess fuel from the pump 2 returns to the chamber 9 via a check valve 19 and excess fuel entering the chamber is returned to the tank 5 through a constriction 16. An electromagnetically actuated valve 24, in a by-pass conduit 23 connecting the output conduit 17 of the pump 2 to the engine air inlet manifold g, is connected in parallel with the starter h to be opened when the starter is operated and thereby provide a richer mixture for starting. A filter 7 is provided in the inlet conduit 6 to the pump 1 and a filter cartridge 12 is mounted in the chamber 9.
