Title: Machine for filling tubes with a material in powder form
IPC: H01B7/16
Filed: 1946-08-21
Abstract: 627,306. Wire resistances. METALLURGIE DU NICKEL. Aug. 21, 1946, No. 24976. Convention date, Feb. 8, 1945. [Class 37] [Also in Groups XI and XVII] A machine for filling tubes with powdered material, particularly for the manufacture of armoured resistances and heating elements in which a resistance is enclosed in a metal tube and tightly packed with refractory powder such as magnesia, consists of a powder-feeding funnel having a feeding. tube attached to it and vibrated vertically, this tube being held friction-tight so that it slides up in its support when the powder is packed sufficiently tightly in the tube being filled. The powder is contained in a funnel 13 to which is attached a feeding-tube 11, the whole being mounted in a holder 13a which is vertically slidable on rods 3, 3<SP>1</SP>. The tube 11 is held friction-tight between jaws 14, the pressure between which is adjustable by means of a screw 15 and spring 16. The jaws 14 are carried by a block 17 which slides vertically on a rod 4 and is reciprocated by a cam within a casing 18 against the upward pressure of springs 24. The cam is driven by a motor through a pulley 20. The resistance wire 27 is fastened at its lower end to a plug 6a closing the tube 6 to be filled and is passed through the feeding tube 11, its upper end being hooked to a steel wire hung from a fixed point of the frame. The tube 11 is passed into the tube 6 and vibrated so that the powder is fed into the tube 6 and packed tightly by the reciprocating tube 11. As the powder becomes sufficiently tightly packed the  tube 11 slips in the jaws 14 and allows more powder to be fed.

Abstract: 496,608. Finishing fabrics. MATHER & PLATT, Ltd., BARCLAY, S. F., and WHITLOCK, J. H. Sept. 17, 1937, Nos. 25257/37 and 9703/38. [Class 42 (i)] Tentering.-Each pivoted entering rail a of a tentering machine is automatically adjusted to suit the width of the fabric treated by means of two single-acting or one double-acting compressed-air cylinder b. As shown, the cylinder b is attached to the rail a and the normally stationary piston c can be adjusted by means of a screw x and hand wheel y.

Title: Improvements in or relating to transfer moulding presses
IPC: B29C45/53
Filed: 1965-06-15
Abstract: 1,112,344. Transfer moulding presses. T. H. & J. DANIELS Ltd., and H. M. GARDNER. 15 June, 1966 [15 June, 1965], No. 25336/65. Heading B5A. In a transfer moulding press, the length of the transfer stroke of a transfer plunger is controlled by automatic control means, subsequent to an initial movement of the plunger to consolidate rubber or thermosetting plastics material in the transfer pot. The control means comprises a switch 16 which is actuated by a rise in pressure of hydraulic fluid in a line 14 as a transfer plunger 11 consolidates material in the transfer pot 12. The switch 16 then energizes coils (17), (19) (Figs. 3, 4, not shown), the former causing a gripper 18 to grip rod 22 adjustable in length at 25 and carrying a cam 23, the rod 22 then rising with the plunger 11, the latter coil 19 ensuring that contacts (20) remain closed when or if hydrualic pressure drops. Material is injected into a mould 13 until the cam 23 opens a normally closed microswitch 24 which simultaneously causes the plunger 11 to retract and also de-energizes the coils (17), (19) with resultant release of the gripper 18, thereby allowing the rod 22 to resume its initial position, with the plunger 11, ready for the next cycle. Withdrawal of the cam 23 also re-sets the switch 24.

Abstract: 1,090,026. Oscillating machines. MALLORY BATTERIES Ltd. June 15, 1965 [June 15, 1964], No. 25343/65. Heading H2A. [Also in Division F2] An oscillating motor comprises at least one armature 16a, passing through a coil 10 having permanent magnets 61, 63, and pivoted by means of a one-way clutch 19a which converts the oscillatory motion to unidirectional rotation of an output shaft 18. As shown, the output shaft 18 carries two one-way clutches 19a, 72 attached to respective armatures 15a, 71. U-shaped permanent magnets 61 ... 64 are provided, polarized so that when A.C. flows in coil 10, the armatures 15a, 71 oscillate in opposition hence one way clutch 19a provides rotary output motion during positive half cycles and the other clutch 72 operates during negative half cycles. Figs. 1-11 (not shown) relate to arrangements using a single oscillating armature and apertured permanent magnets, the output shaft being pivoted in a second oneway clutch fixed to the mounting. In Fig. 1 (not shown) the motor drives cam-operated timing switches (for a washing machine) via a train of gears. Figs. 5-8 (not shown) relate to the construction of one-way clutches 19a, 72 (see Division F2) in which spring-loaded rollers are interposed between the output shaft and the concentric outer ring on which the armature is mounted.

Title: Improvements in or relating to radar systems
Inventor: WATT JAMES
IPC: G01S13/937
Filed: 1964-06-19
Abstract: 1,086,874. True motion radar. MARCONI CO. Ltd. April 28, 1965 [June 19, 1964], No. 25510/64. Heading H4D. The Specification describes a True Motion P.P.I. radar, similar to that shown in Fig. 1 of Specification 1,023,927, in that the recording tape with one writing and four reproducing heads is replaced with a recording tape 19 having a single writing and/or reproducing head 18, and the four-contact commutator switch feeding the selected reproducer head output to the display tube is replaced by a single contact switch 26 actuating a relay A. The recording tape 19 rotates once in 2 mins., i.e. once per 60 revs. of the antenna 1. Shaft 29, which rotates the wipers of switches 32 and 33, 59 rotates at - revs. per min. such that a wiper 8 2 remains on any contact for - min. Relay A is 59 2 thus actuated for - min., such that contacts 59 A1 and A2 are moved down for the same period. 2 8 Thus for - min. every - min. the echo signals 59 59 from amplifier 17 are recorded on the recording tape, and simultaneously displayed on the 2 display tube. In - min., the antenna 1 rotates 59 1 through 1 - revolution. Fifty-nine such record- 59 ings can thus be recorded on the tape. Since 1 only every fourth of these 1 - revolution scans 59 is recorded, it takes 8 minutes for the tape to be completely filled. During the time that the relay is actuated the wipers of switches 32 and 33 are on earthed contacts, such that the echoes are not displaced, and the " at present " display is shown with the " own craft " echo at the centre of the screen. The wiper of switch 26 then moves off of contact 27 such that relay A is deenergized and contacts A 1 , A 2  and A 3  return to their upper position. The head 18 is now reproducing the echoes on the tape portion next to that which has just been written on, which echoes were written on to the tape portion 6 mins. or three tape revolutions previously. The thus read 6 mins. old echoes are fed to the display tube. The wipers of switches 32 and 33 are on contacts connected to points on the resolvers that give the movement of the craft in the 6 previous minutes. The 6 mins. old echoes are thus displayed with the correct displacement to give the required accelerated true motion display. The next echoes to be reproduced are 4 mins. old, and the switches 32 and 33 accordingly adjust to give the appropriate displacement signals. The display is then repeated for echoes 2 mins. old, and then, with the wiper of switch 26 back on contact 27 and relay A actuated, the present echo position is displayed and recorded. Means are described, Fig. 2 (not shown), whereby additional displacement signals are fed to the display such that the present positions of the " own craft " does not remain in the centre of the display but moves according to its true motion.

Abstract: 844,855. Springs. THORNE, I. J. Nov. 25, 1957 [Aug. 23, 1956], No. 25813/56. Class 108(3). [Also in Group XXV] A multiple spring arrangement has the resilient members arranged coaxially and in such a manner that they are brought into action successively. As applied to counter balancing means for the tailboard ramp 2 of a vehicle or container 1 the arrangement comprises two springs 7 and 8 which are disposed within a tubular casing 5 secured to the vehicle body. A plunger 13 rests on the lower spring 7 and is connected to the ramp by a folding link 16, 16a. The upper spring 8 is carried between an abutment 14 on the upper end of a rod 12 secured to the plunger and a sleeve 10 slidable both on the rod and, to a limited extent in the downward direction, within a collar 6 carried on the casing 5. As the ramp is lowered the plunger and the sleeve descend, compressing the spring 7, until a shoulder on the sleeve abuts the collar 6 to arrest the downward movement of the sleeve. Further lowering of the ramp compresses both springs.
