Abstract: 876,380. Holders for binding-metal. POWER STRIPPING SYSTEMS Ltd. Oct. 14, 1959 [Nov. 18, 1958], No. 37016/58. Class 120 (2) [Also in Group XXVIII] A holder for binding-metal comprises a frame 11 supporting a spool 10 which rotates about a substantially vertical axis and on which a coil of binding-metal is placed or wound, friction means 32, e.g. a washer or pad, between the frame 11 and the spool 10 to provide a friction force due to the weight of the spool and coil, which resists rotation of the spool, retaining means 35 for confining to the spool loops of the coil which become loose and guide means 28 through which binding-metal is led to the using appliance. In the form shown in Figs. 1 and 2, the Y-shaped holder frame 11 has two arms 12 and a stem 13 radiating from a central joint which is surmounted by a pivot 19 for carrying the spool. The arms 12 are joined by an arcuate bar 15 carrying a pair of wheels 16 on to which the holder may be tilted for transportation. The spool 10 comprises a pair of flat circular cheeks 20, 23 which are interengaged by upstanding pins 22 fixed to the lower cheek 20 and passing through the detachable upper cheek 23, the cheeks preferably being held together by a releasable clamp 24 which bears against the detachable cheek 23 and is resiliently anchored to the lower cheek 20. The detachable cheek may be held in its working position by nuts which screw on to the pins 22. C-shaped spring members 33, spaced around the spool, have loop retaining hooks 35 and tails 36 which bear resiliently on the lower cheek 20. A straight tube, tangential to the coil of strip or wire and having a divergent nozzle 31, guides the metal to the using appliance.

Abstract: 905,389. Surgical syringes. PHILLIPS PTY. Ltd., N.J. Jan. 27, 1961 [Oct. 31, 1959], No. 37021/59. Class 81 (2). A drenching gun comprises a pump cylinder 2 with a reciprocable plunger 11, a coaxial inlet chamber 4 and an outlet chamber 6 communicating with the inlet chamber, diaphragms 25, 30 being provided in the inlet and outlet chambers, respectively, to close an inlet chamber supply pipe 5 and open an outlet chamber discharge pipe 8 on a pressure stroke of the plunger and to open the supply pipe and close the discharge pipe on a suction stroke of the plunger. The cylinder 2 is supported in a holder 1 which also forms part of a hand grip including a bellcrank lever 13, 17 for reciprocating the plunger. The pressure stroke of the plunger is effected manually, the diaphragm 25 in the inlet chamber then closing the supply pipe 5 so that liquid flows from the cylinder through the inlet chamber and a connecting pipe 7 to the outlet chamber 6. The outlet chamber comprises a bellows 31 carrying the diaphragm 30 and mounted on the discharge pipe 8 and is protected by a cape 33. Passage of liquid into the outlet chamber lifts the diaphragm 30 from the discharge pipe so that liquid flows to a nozzle 9 via the discharge pipe 8 and tubing 34 which, according to the Provisional Specification, may be transparent. The bell-crank lever on release is returned to its starting position by a spring 16 to effect the suction stroke of the plunger. The diaphragm 25 which is connected by a perforated bellows 26 over the end of the supply pipe is then raised from the supply pipe so that liquid flows through the bellows perforations into the cylinder. The diaphragms may be made of neoprene.

Abstract: 1495190 Annealing glass PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Sept 1975 [24 Sept 1974] 38588/75 Heading C1M [Also in Division F4] Glass articles are annealed by conveying them on a metal gauze belt 11 through a furnace tunnel 13 which is divided into zones having a temperature-controlled gas flow which is maintained in a direction transverse to the direction of transport of the articles. The gas flows in the individual zones are controllable independently of each other by fans 15 and heating elements 19 and the gas flow across the zones is varied by the size of the flow apertures 23 and 27 in the zone partitions 21 and 25. The furnace may have a heating section 3 with heating zones 5 followed by a cooling section 7 with cooling zones 9. The apertures 23 in the heating zone partitions 21 can be progressively increased along the length of each zone so that gas flow increases and thus a linear temperature gradient is maintained in each zone. Similarly in the cooling section the apertures 27 can be progressively increased so that a linear cooling gradient is maintained.

Abstract: 1364436 Theft alarms EURONICS Ltd 10 Nov 1971 [11 Aug 1970] 38621/70 Heading G4N [Also in Divisions H4 and H3] Unauthorized removal of articles through an exit is detected by a receiver at the exit which responds to the field produced by a batterypowered oscillator concealed in each article, and which operates an alarm. The oscillator shown produces bursts of r.f. at a pulse rate in the audio range, so that the receiver can operate an audio alarm at that frequency, and so that battery life is prolonged. The timed circuit LC1 determines the r.f. and C3R2 determines the duty ratio of the pulses of r.f. oscillation; or if R2 is shorted out and C3 omitted the feedback circuit C2R1 will control the duty ratio. The radio frequency is between 10KHz and 10MHz and is preferably 500KHz; the duty ratio is between 10 and 1000 to 1, and preferably the bursts last for 35 Ás and the gaps for 1À3 mS. By selecting different gaps, different audio tones are produced by the alarm for different articles. A portable receiver and alarm also may be provided. An alternative oscillator circuit replaces T by a dual gate FET, one gate being connected through a diode to the source, and the other gate to the upper end of LC1, the two gates being also connected across C2.

Abstract: 1280494 Measuring ultraviolet radiation DETEC S A 4 Aug 1969 [5 Aug 1968; 4 June 1969] 38924/69 Heading G1A To measure the intensity of ultraviolet radiation emitted by a U.V. tube in a narrow band of wavelengths including 2537A, which intensity is indicative of the germicidal efficiency of the tube 1, a filter 3 for passing only the above wavelength band is situated between the tube and a photo-cell 4 whose output is fed to a threshold device including a signalling device 7. As shown in Fig.1, a shutter 2 is placed between the tube and one or more interference filters 3, the shutter ensuring that light is incident on the photo-cell only when it is desired to make an intensity measurement. In the embodiment of Fig.2, the shutter movement is controlled by a relay 10, and with the shutter open, when the intensity of light in the narrow wave band is below a predetermined level transistor 5 becomes conducting. Thus, relay 14 closes contact 15, causing operation of multivibrator 6. In this way, neon lamp 7 flashes intermittently when the radiation intensity is below a predetermined level. Alternatively, indicator 7 could give acoustic signals. In further embodiments Figs.3 and 4 (not shown) the circuitry is modified such that the neon lamp flashes when the radiation intensity is above a predetermined level, which level may be adjusted using a potentiometer (77). The single photo-cell may be replaced by a plurality of photo-cells connected in parallel.
