Title: Tape wrapping machine
IPC: H01F41/12
Filed: 1964-04-16
Abstract: 1,021,729. Applying adhesive tape. MIDLAND ENGINEERING & MACHINE CO. April 16, 1964 [May 21, 1963; Jan. 10, 1964], No. 15889/64. Headings B8F and B8G. Apparatus for wrapping a layer of pressure adhesive tape around the perimeter of an article-for example an electrical coil-comprises a rotatable arbor 18 for supporting the article, and a tape feeder 20 adapted to move into contact with the article to apply the tape end T1 thereto and to move away therefrom, as the arbor rotates to wind the tape thereon. The tape is unwound from a reel 27 under an adjustable force exerted by screw 31 and passes via a coder 265 movable by a crank-shaft 285 between ink pad 272 and a pressure block 275, and via pulleys 37-39 to roll 54 mounted on shaft 56 having clutch 55 to allow only forward movement of the tape. Plate 50 of the tape feeder is mounted on crankshaft 70, Fig. 3a (not shown), and is pivotally connected at its base to a lever 80 pivoted at 82 so that on rotation of shaft 70 the tape feeder moves so that a pad 60 of sponge rubber and adjustably mounted on plate 50 applies the tape end to the article. The rotation of the crank-shaft back in the opposite direction causes the arbor to rotate and a wiper 150 to apply pressure to the tape on the article to ensure adhesion of the tape thereto. As the feeder returns to its original position the tape is cut by blade 155. The wrapped article is pushed off spindle 18 by ejector fingers 178, Fig. 7 (not shown). A pneumatic system is described which sequentially operates the various apparatus features. In a modification, wiper 150 is replaced by a wiper blade 304, Figs. 9 and 10 (not shown), mounted on an arm which is moved by a cam during rotation of the arbor so that the blade engages the article.

Title: Improvements in or relating to record controlled statistical machines
Inventor: PARMENTER RAYMOND OWEN
Filed: 1955-06-02
Abstract: 779,036. Statistical apparatus. POWERSSAMAS ACCOUNTING MACHINES, Ltd. June 1, 1956 [June 2, 1955], No. 15895/55. Class 106 (1). In a record-card controlled statistical machine of the kind having columns of selectively settable elements 1 supported for independent vertical movement to and from inactive positions and for each column a horizontally sliding latch plate 9 having pins 8 to engage projections 6 on the settable elements so as to retain any element 1 moved to the active lower position, the latches are each positively moved to the retaining position at the correct instant by a camming pin 14 rotating on a drum 15 and adapted to contact the end of the latch plate. In high-speed card sensing the latch plate is displaced by the cam face 7 of element 1 at such a speed that the normal latch spring 13 is sometimes unable to return it to the latching position sufficiently quickly. The cam pins 14 are provided to ensure that the latch plate returns effectively and to prevent its bouncing. Where the cards are sensed column by column the pins 14 are staggered around the periphery as shown. A group e.g. of ten columns may be sensed at once, the eighty pins then being arranged so that there are ten pins in each of eight angular positions. Alternatively, where all the columns are sensed at once, all latches may be moved to locking position simultaneously. In another form pins on the elements 1 engage in openings formed in the latch plate, the openings having latching projections with camming and latching surfaces such as are provided on projections 6.

Title: Improvements in and relating to hot plates for gas cooking stoves
IPC: F24C15/10
Filed: 1918-10-05
Abstract: 161,992. Helps, G. Oct. 5, 1918. Gas cooking-stoves.-Comprises detail im- - provements relating to the burners and gassupply fittings for the hot-plates of gas cooking stoves. The tap-rail, i.e. the tube upon which are mounted the plug cocks 8 supplying gas to the burners, is removably attached to the hotplate 1, Fig. 2, by a clamping-screw 6, which passes into the lug 16 on the hot-plate. A slot 19 is formed in the web on the tap-rail 5 to enable the rail to be raised and lowered relatively to the hot-plate 1. The burners 4, Fig. 6, are also adjustable vertically, being carried in a stirrup 32 fitted to the hot-plate 1. A boss 42 on the burner fits into an aperture 34 in the saddle and the burner is adjusted vertically by screws in holes 35; the upper ends of the screws bear upon the collar 41 on the underside of the burner. In modifications, the socket 34 may be screwthreaded to receive a large screw-threaded adjusting-ring. The barrels 7 of the plug cocks 8 are made integral with the tap-rail. To enable the plug cocks to be removed readily for cleaning the nipples, they are kept in place by a rotatable plate 20, Figs. 3 and 4, which bears on the shoulders 21 on the plugs. The plate 20 is fitted loosely on a spindle 22, which is screwed into a hole on the rail 5, and passes through a spring 23 in a boss on the rear side of the plate 20. A cam-shaped ring 24 is rotatable on the spindle 22 so that its projecting parts engage with the boss and lift the plate 20 from the shoulders 21; the plate 20 may then be easily rotated to a position between and free from the plugs 8, which may then be withdrawn. In modifications, the plate 20, Fig. 12, is on a spring-supported pin 22, and the plug 8, Fig. 13, is secured by a spring 81 and cap 80 which is attached to the barrel by a bayonet joint. A main plug cock 27, Fig. 5, is fitted in the rail 5, and is kept in place by a screw cap 28. Fig. 9 shows a rotatable tap-rail 5, the conical end of which fits into the end of the gas supply pipe; it is retained in position by a catch 69 and by a pin 38 passing through brackets 37, and may be swung down to facilitate the cleaning of the nipples.

Title: Improvements in or relating to axle suspensions for motor vehicles
IPC: B60G7/02
Filed: 1964-04-20
Abstract: 1,012,078. Road vehicle spring suspension. DAIMLER-BENZ A.G. April 20, 1964 [April 20, 1963], No. 16237/64. Heading B7D. In a motor vehicle having driven wheels 14 carried by links 15 swinging about transverse axes or, as shown, oblique axes, the links 15 swing about a rigidly aligned articular connection on a gear casing 21a (Fig. 4), suspended from the superstructure 25 of the vehicle by resilient mountings 11a, 13a, and thrust rods 17 rigidly or pivotally connected to the links 15 near the wheels 14 are attached to the superstructure 25 by elastic supports 18. The resilient mounting 11a comprises a rubber sleeve (Fig. 7, not shown), providing resilience chiefly in the longitudinal direction of the vehicle, and the resilient mountings include rubber bushes (Fig. 8, not shown) recessed to provide resilience chiefly transversely of the vehicle, so that a transverse load P (Fig. 1, not shown), on one wheel is reacted at the mounting 11a to produce a turning moment which is resisted across almost the whole width of the vehicle by axial forces (P 1 ) along the thrust rods 17. Angular displacement of the wheels under horizontal loads is thereby reduced and undesirable steering effects avoided. A socket 15a on each arm 15 is pivoted on a pin 16 secured to the gear casing 21a by needle or roller journal and thrust bearings (Fig. 6, not shown). The rear of the gear casing 21a is connected to the resilient mountings 13a by a cross-member 23 which may be a leaf-spring. The elastic supports 18 for the thrust rods 17 comprise rubber buffers (Fig. 9, not shown), clamped against opposite faces of walls 48 on the superstructure 25. Coil springs 28 support the superstructure 25 on the links 15. In another embodiment, Fig. 2, the links 15 are articulated on a member 19 connected to the gear casing 21 about a vertical pivot 20.

Title: System for recording and reproducing pulse code modulated data
IPC: G11B5/02
Filed: 1964-04-20
Abstract: 1,045,207. Magnetic record/playback processes; electrical digital data storage. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. April 20, 1964 [May 10, 1963], No. 16373/64. Headings G4C and G5R. To improve the signal/ noise ratio, and/or the packing density of P.C.M. data on a magnetic tape, the signal (A), Fig. 6, is played back by a head, Fig. 2, whose gap-length is at the turnover point for high-frequency response (Fig. 1, not shown), and is so related to the wavelength # of the fundamental (unmodulated) p.r.f. that the waveform (A) is integrated to the triangular form (B). This also corresponds to maximal playback sensitivity. The waveform (B) is then filtered (C) and then amplified and limited (D) to give a waveform which, for some purposes may be a sufficiently good representation of the recorded waveform (A). However, the waveform (A), containing effectively two different p.r.f's., reacts at the filtering stage to produce a differential phase response, which may render the waveform (D) insufficiently accurate for some purposes. Accordingly, a clock waveform (E), (the unmodulated carrier) is recorded at the same time on an adjacent track and this is similarly played back and integrated (F) and amplified and limited (G), no filter being required. Narrow pulses (H) are derived from the waveform (G) and fed, together with waveform (D) to a sampling circuit (Fig. 7, not shown), whose output (I) is readily converted to a replica of the waveform (A) apart from a small but constant phase delay (J). In a further embodiment (Fig. 5, not shown), a multiple-track tape carries a number of data tracks all modulated on to the same carrier together with a single clock track for processing the outputs as above.
