Title: A ventilator grating and securing means therefor
IPC: F24F13/08
Filed: 1966-09-15
Abstract: 1,123,667. Ventilator grilles. GEBRUEDER TROX G.m.b.H. 15 Sept., 1966 [24 Sept., 1965], No. 41200/66. Heading F4V. A frame 5 of a ventilator grating is fixed to the rear flange 4 of a frame 1 lying against a wall by means of a clamping strip 17 operated by a screw on which the strip is mounted. The strip has a synthetic plastics sheath 19 which produces a braking effect so that the strip 17 will not hang loosely on the screw. The screw is carried in a housing 10 secured to the frame 5. To fix the frame 5 in position the screw is turned to engage the strip 17 behind the rear flange 4 and further turning of the screw tightens the strip. A seal 7 is provided beneath a flange 6 on the frame 5.

Title: Improvements in or relating to sweep frequency signal generators
IPC: H03B23/00
Filed: 1965-09-29
Abstract: 1,110,398. Automatic frequency control. SIEMENS A.G. 29 Sept., 1965 [30 Sept., 1964], No. 41290/65. Heading H3A. A sweep frequency generator has its output frequency automatically controlled by the output from a differential amplifier to the inputs of which are applied a periodic waveform, e.g. a sawtooth, and a voltage derived by a discriminator from the output signal of the signal generator. The triangular waveform is compared with two reference potentials in a comparator which produces an output pulse whenever the triangular wave coincides with a reference potential, and the output pulses are applied to change the state of a bi-stable circuit so as to produce a square wave signal. This signal is then integrated to form the triangular wave signal.

Title: Fuel cells and separators therefor
IPC: H01M12/02
Filed: 1963-10-22
Abstract: 1,066,465. Fuel cells; primary cells. MONSANTO CO. Oct. 22, 1963 [Oct. 22, 1962]. No. 41596/63. Heading H1B. The separator (10, 11) of a fuel cell is moved continuously past electrodes 12, 13 fuel and anolyte being applied at 14 and oxidant and catholyte at 15. The tapes can be wound on a spindle 18 by clockwork. In many modifications the separator may be a single tape and may carry any or all of the components of the cell, having the stationary part merely to function as carrier collectors. Thus, fuel and oxidant may be supplied in liquid form by running the tapes through baths before they meet the current collectors, or by including encapsulated liquids in the tape. Gases may be pressed in a plastics foam applied to the tape (e.g. fluorine gas) and solid fuel and oxidant can be coated on the tape. A dissolving electrode (e.g. Mg,. Zn, Al) may be used on the tape to give a primary cell couple. The tape may be endless and cut to feed fuel &c. to the reactive sites and the current collectors (or electrodes) may be in the form of rollers or endless bands thus facilitating depolarization by a continual change of surface. Many fuels or anodic materials are disclosed, including urea, guanidine and glucose and many solid and liquid oxidants, including organic oxidants such as meta-dinitrobenzene. A copper, copper oxide couple can be used as oxidant and in this case an endless copper band forms the electrode and is re-oxidized by the atmosphere. The separator may be of ionexchange resin.

Title: Device for feeding filament to looms
IPC: B29D5/06
Filed: 1964-10-12
Abstract: In a loom for weaving a coiled filament into the edge of a weave to form a slide fastener the filament is fed to the fell of the weave by a continuously rotating feed roll whenever the slack in the filament is taken-up, and the filament becomes taut about the roll.  The device comprises a fixed housing (20, Figs. 4, 5, not shown) having a helical groove (23) around its inner periphery and a feed roll (26), rotated faster than the linear speed of the filament and the weave. The filament is normally disposed in the groove but engages the roll when it becomes taut so that a predetermined amount is fed out.

[Also in Division D1] A former 10, about which wire is to be wound to form a tyre bead, has outer and inner gripping members 50, 46 between which the leading end of the wire W can be gripped, the inner member 46 being displaceable towards the outer member 50. The outer gripping member 50 is pivoted at 22 so that it can be rocked inwardly to permit a finished tyre bead to be removed from the former. Outward rocking of the gripping member 50 beyond the desired configuration of the former 10 is prevented when a pin 38 on the member 50 engages a static hook 36. Both gripping members 50, 46 are biased towards each other by springs 24, 28. A cam 76 is used to displace a system of links 58, 62 to control the setting of the member 46.

Heading B1V. An emulsifying device comprises a casing 9 housing a magnetostrictive transducer including a core vibrator 5 supporting a concentrating rod 15 which projects into a chamber 1 to which liquids to be emulsified may be admitted via 19 and 21. The rod has annular projections cooperating with grooves in the wall of the shamber to form a tortuous path for the liquid under treatment, and one component is fed (via pipe 21) onto the end face of the rod. In the Fig. shown, 4 is a magnetic core divided longitudinally into four blocks, 2 is a coil surrounding the core, and the whole transducer is cooled by water supplied via pipe 14 in lid 10. Water for the emulsion enters the chamber I at 19, mixes with the non-aqueous phase (e.g. a flotation agent) fed in at 21 and passes around element 15 to an outlet 17 or 20. An alternative form of magnetostrictive transducer is illustrated in Fig. 4 (not shown) in which the vibrator is slotted longitudinally and provided with coils wound directly on opposite sides of the slot. The apparatus may produce ultrasonic vibrations.

Title: Improvements in or relating to static invertor circuit arrangements

Abstract: 1,108,171. Semi-conductor invertor circuits. PLESSEY-UK. Ltd. 28 Oct., 1964 [28 Oct., 1963], No. 42426/63. Heading H3T. [Also in Division H2] In a static invertor circuit arrangement having a square wave output including two- or more semi-conductor controlled rectifiers 10, 11 the trigger pulse to initiate the conduction of the reset rectifier or rectifiers is caused by the saturation of a saturable core inductor which has a winding 19 coupled to the load winding 13, 14 of the invertor. With rectifier 10 conducting the right hand end of winding 19 becomes positive and capacitor 22 charges through resistor 23. When the inductor core saturates the p.d. across winding 19 collapses and the capacitor provides a positive potential to gate electrode 20 of the other rectifier 11, which causes it to conduct. Rectifier 10 stops conducting because of a reverse bias across it, resulting from the discharge of commutating capacitor 18. This switching process is repeated so as to produce a square wave output from winding 16. In a bridge connected invertor circuit (Fig. 2, not shown), employing four controlled rectifiers, the saturable core inductor is provided by a separate transformer (33) coupled to the main invertor transformer (31) by a trigger winding (32). In a further circuit (Fig. 3, not shown), the frequency of the invertor is stabilized by connecting a double- Zener diode (40) across the winding (32). The frequency may be varied by including a transductor in the coupling circuit (Fig. 4, not shown).

In a method for the detection or determination of e. g. traces of insecticide in a carrier gas, the gas to be investigated is subjected to a flameless combustion on a catalytic surface prior to its entry into a detector selectively responsive to non-metallic elements of the Vth and/or VIth and/or VIIth main group of the periodic system (excluding oxygen). This combustion removes substances which would interfere with the detection of the non-metallic elements referred to above e. g. the presence of solvent which has been used to extract the insecticide traces from sample victuals, and which has subsequently been evaporated. Oxygen for supporting the combustion may be supplied if not already present. Suitable catalysts may be platinum black, copper oxide or a glowing quartz tube.
