Title: Improvements in or relating to transfer sheets
Inventor: HOLTZ HERMANN
IPC: B44C1/17
Filed: 1966-03-16
Abstract: 1,116,008. Transfer. H. HOLTZ. 16 March, 1966, No. 11460/66. Addition to 1,025,170. Heading B6C. In a transfer as described in Specification 1,025,170 (Heading B6C) the adhesive coating is applied to the transfer and to the free surface of the backing sheet, the materials for the adhesive coating being such that when applying the coating to the free surface of the backing sheet a reaction takes place thus causing the cold-acting adhesive effect to be exerted exclusively on surfaces of the transfer symbols. In a preferred embodiment the backing sheet is polystyrene and the adhesive coating comprises polyisobutylene, a commercial resin or wax, a commercial heat-activated sealing material (e.g. a polyvinyl compound) and a solvent for polystyrene (e.g. toluene). The surface of the backing sheet remote from the transfer may be coated with a silicone.

Abstract: 976,357. Winding thread on cores. STANDARD TELEPHONES & CABLES Ltd. March 22, 1963 [March 27, 1962], No. 11626/62. Heading B8G. On each revolution of the thread 5, Fig. 1, about the core 1, the thread 5 deflects and vibrates a probe 7 to vibrate and produce an output from a microphone 11. The output from the microphone is amplified at 14 to maintain electromagnetically controlled switches 15 closed. If the thread 5 is broken or exhausted the probe 7 is no longer vibrated and the switch 15 is opened to stop the machine. In Fig. 2 the two-armed lever 16 can rock about the pivot 17. As the cord 23 is wound around the core 24 it strikes an inclined member 22 on the lever 16 to rock the lever clockwise and this displaces a permanent magnet 20 relatively to a winding 21. Thereafter the lever returns to the position shown under gravity. The output signal from the winding 21 is used to control the switch 15. The probe 7 in Fig. 1 may be deflected not by the thread 5 but by teeth on a wheel that is being rotated by the thread.

Title: Number comparing systems
IPC: G06F7/02
Filed: 1961-03-30
Abstract: 932,502. Comparing digital data. WARNER & SWASEY CO. March 30, 1961 [April 21, 1960], No. 11711/61. Class 106 (1). A circuit for comparing two multi-digit binary numbers R, D, and adapted to provide a first output signal if R > D and a second output signal if R # D, comprises a plurality of stages, each stage being supplied with corresponding digits of the two numbers and with a control signal from the next higher stage. Fig. 3 shows a single comparison stage, the digits R<SP>9</SP>, D<SP>9</SP> being applied at terminals 101, 102 respectively and a control signal from the next higher stage being applied at a terminal 100. Binary " 1 " and " 0 " are represented by high and low potentials respectively. The signal applied at 100 is normally low and is inverted at 112 and supplied via a line 113 to condition an " and " gate 108 which is supplied with digit R<SP>9</SP> and the complement of digit D<SP>9</SP> to provide a high output if R<SP>9</SP> = 1, D<SP>9</SP> = 0, this output being inverted at 130 and applied over a lead 131 to an " and " gate 134 also fed with corresponding leads from the other comparison stages. The line 113 is also connected to "and" " gates 115, 118 supplied with R<SP>9</SP> and the complement of D<SP>9</SP>, the outputs of these " and " gates being supplied to an " or " gate 124 which feeds an inverter 126, the output of the inverter at 127 being connected to the terminal 100 of the next lower comparison stage. The potential at 127 is high if R<SP>9</SP> = 0 and D<SP>9</SP> = 1 or if the potential at 100 is high and in these circumstances the gate 108 of the next lower stage is inhibited so that a high output is applied on the lead 131 of the lower stage. Thus if the higher digits are equal, the corresponding leads 131 are at a high level to condition the " and " gate 134. If at any stage the corresponding D digit is greater than the R digit, the output at 127 of that stage is high to inhibit all the lower " and " gates 108 and cause a high output on their leads 131. The gate 134 is thus opened to produce a high level on a lead 80, which level is also produced if all the R digits equal all the D digits. In all other circumstances the gate 134 is inhibited and the potential on 80 is low. The lead 80 may be arranged to operate a relay (Fig. 1, not shown). The various gates comprise diodes and the inverters triode tubes (Fig. 2, not shown). Reference has been directed by the Comptroller to Specification 836,234.

Title: Improvements in or relating to electron beam electric discharge tubes wherein an electron current is formed into a beam
IPC: H01J29/62
Filed: 1950-05-11
Abstract: 683,491. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 11, 1950 [May 14, 1949], No. 11772/50. Class 39(i) In a cathode ray tube of the kind in which an axial potential gradient is set up along one or more concentrating electrodes of high resistance material by current flow therethrough, at least 30 per cent of this current consists of electrons from the beam. If the concentrating electrode voltages vary slightly the number of electrons collected thereby also vary in such a manner as to maintain the focusing constant. The concentrating electrodes may be of semiconducting material or of insulating substance coated with such material and the effective resistance in the direction of the beam is 1-5 megohms. In one form, Fig. 1, two flat concentrating electrodes 3, 4 are used with a flat electron beam, and both ends of each of the concentrating electrodes 3. 4 are connected to an external battery. Under the action of deflecting plates 5, 6 the beam falls on anode 7 or 8. In a modification, Fig. 2 (not shown) the ends of the concentrating electrodes adjacent to the cathode are connected to the cathode instead of having separate external leads. In this case the current from the beam is about half the current through the concentrating electrodes, and the Wehnelt cylinder 2 may be dispensed with. In another modification, Fig. 3 (not shown) the concentrating electrodes are left entirely free at their ends adjacent the cathode so that only current from the beam can flow through them. In another form, Fig. 4, the beam is convergent and the concentrating electrodes 14, 15 converge correspondingly. In all forms the beam may be of circular section in which case a single cylindrical concentrating electrode is used, and the electrodes 7, 8 'may be replaced by a fluorescent screen or by a single collecting electrode. Further deflecting plates, accelerating electrodes, diaphragms may be provided. The beam may be divergent instead of parallel or convergent. Since the collected electrons do not all traverse the concentrating electrodes through their entire length the potential may be made to vary as x <SP>4</SP>/ 3  where x is the distance from the cathode while keeping a constant resistance per unit length, which is the condition required for maintaining a parallel beam. A prior art arrangement is described in which the current through the focusing electrode is produced solely by an external battery and in which the desired x <SP>4</SP>/ 3  variation is obtained by making the electrode conical or by compressing it more at the end adjacent the cathode so as to make the resistance per unit length increase with distance from the cathode.

Abstract: 1,132,372. Blasting. BADISCHE MASCHINENFABRIK G.m.b.H. 17 March, 1966 [23 March, 1965], No. 11773/66. Heading B3D. Castings, forgings and the like are cleaned by being blasted by a centrifugal wheel 2 while in a drum 1 rotating about an axis inclined to the horizontal. The top end of the drum has a charging opening 3 covered by a stationary plate 4 comprising a pivoted cover 6; when the latter is opened, a batch of workpieces passes from a bin 7 into the drum. The bottom end of the drum comprises two parts 8, 9. The part 8 is secured to the wall of the drum and to a housing 10 mounted in a bearing 16. The part 9, forming a discharge cover, is carried by an arm 11 pivoted at 13 to the housing 10 and actuated by a pneumatic or hydraulic cylinder 12 secured to a stationary part by a universal joint 15; a connecting link has a pivotal connection 14 with the arm 11 and is connected to the piston rod 12<SP>1</SP> by a bearing 14 so as to be freely rotatable about the axis of the cylinder 12. The parts 8, 9 are partially or entirely perforated so that blasting medium passes from the drum into a conveyor 17. When the batch of workpieces has been cleaned, the discharge cover 9 is opened to discharge the workpieces; at the same time or shortly before, the supply of abrasive medium to the wheel 2 is interrupted, the wheel continuing to rotate. The cover 9 opens when it is 30-120 degrees before its lowest position and closes when it is 30-120 degrees after its lowest position. A fresh batch is then admitted to the drum and the supply of blasting medium to the wheel 2 is restarted. The operations may be controlled manually or automatically.

Abstract: <PICT:0811128/IV (a)/1> <PICT:0811128/IV (a)/2> <PICT:0811128/IV (a)/3> Apparatus for supplying a spinning solution to a jet to form slub yarns comprises a metering pump provided with an intermittently opened by-pass valve, which permits the intermittent connection of the output side of the pump with the input side, and a throttle valve, in series with the by-pass valve, to enable the differences in cross-sectional area of the yarn to be varied.  As shown in Figs. 1 and 2, the pump body consists of end plates 1, 2, a shell 3 and a coverplate 4.  The pump members are two meshing gear-wheels 5, 6, wheel 5 being freely rotatable in the shell 3 and wheel 6 being secured by a pin 8 to a driving shaft 7 journalled in the plates 1, 2.  An inlet passage 9 is formed in the plate 1 and an outlet passage 10 in the plate 2, these passages opering on opposite sides of the nip of the gear-wheels 5, 6, as shown in Fig. 1.  The shaft 7 also carries a rotary valve member 11 housed in a cavity 14 of the cover-plate 4 and secured to the shaft by a pin 12.  As shown in Fig. 2, this valve member is a disc having four notches 13 formed in its periphery.  These notches may be equally or unequally spaced, and may be of equal or differing circumferential extent.  The outlet passage 10 in the plate 2 opens into the cavity 14 at 15.  A by-pass passage is formed by a port 16 in the left-hand side of the plate 2, as shown in Fig. 2, leading to a transverse bore 18 in the plate 2 which leads to a bore 19 opening into the cavity 14 in the cover-plate 4 in such a position that it is alternately uncovered and covered by the notches and lands of the valve member 11.  The port 16 is on the inlet side of the gears 5, 6.  The bore 18 is formed with a valve seat 20 and houses a needle valve 21 on a screw-threaded spindle 22, so that the valve can be adjusted in relation to the seat 20 to regulate the rate of flow of spinning solution through the by-pass passage.  As the gear-wheels 5, 6, shaft 7 and valve member 11 rotate, the valve member 11 alternately covers and uncovers the port 19, causing intermittent escape of spinning solution from the delivery passage 10 to the inlet passage 9.  In an alternative construction (Fig. 3), a conventional metering pump 28, which may be of the geared type, delivering spinning solution to a jet 27, is by-passed by a pipe 29 which includes a throttling needle valve 23 and a rotary valve 24 having a number of ports 25. The valve 24 may be driven by the same source of power as the pump 28, or independently, and the valve 23 may be adjusted continuously and automatically, for example by a cam 26 driven by the pump or valve motor, or independently.  Specification 589,038 and U.S.A. Specification 2,391,973 are referred to.
