IPC: A01K49/00
Filed: 1924-01-18
Abstract: 226,055. Richards, A. Jan. 18, 1924. No Patent granted (Sealing fee not paid). Bee-keepers' appliances.-A small box of wood &c. is employed for the reception of a honeycomb cell selected for rearing a queen bee. The box 1, Fig. 3, is formed with an open extension 3 at the bottom through which the cell projects, and is fitted with a screw &c. cap 2 the edge of which supports the box between two frames. The selected cell is cut from the comb by means of a tubular cutter 5, Fig. 2, the cutting-members 6 being attached to a spring 7 that tends to separate them when the ferrule 8 is removed. A protector for the cell consists of a tube of wood &c. split at one end to form a number of divergent strips that fit over the extension 3. The box 1 may fit into a cylinder 11, Fig. 5, of gauze, perforated celluloid, &c. to form an intrcducer cage. The lower end of the cylinder 11 is stopped bv a plug 12 in which is an eccentric opening 13 for candy &c. covered by a plate 14 on the swivelling support 15. The. cylinder 11 may have slots large enough to admit worker bees, the slots being covered at will by a sliding gauze ring. With a similar tube 11 of gauze attached, the box may be employed as a travelling or nursery cage.

Abstract: 436,935. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts Ges.; 2, Friedrich Karl-Ufer, Berlin) Jan. 16, 1934, No. 1605. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 17, 1934]. [Class 38 (ii)] In an inverter comprising valves 2, 3, means are provided for applying a negative voltage of peaked waveform to the grid to the grid of the valve from which current is being commutated to effect deionization. The grids are supplied from a transformer 8 having a primary winding connected across the main transformer 4 through a resistance 9 and additional primary windings 17, 18 which are in series in the anode circuits of the valves 2, 3. At the moment of commutation from, e.g. valve 2 to valve 3, the sudden rush of current through the winding 18 induces a voltage of peaked waveform in the secondary winding supplying the grids, this impulse making the grid of the valve 2 negative. In a modification the transformer 8 has one auxiliary winding which is connected in series with the condenser 7.

Abstract: 183,153. Greenwood, W. Slater-. Jan. 17, 1921. Lantern shutters. - To prevent dazzle in vehicle lamps &c. provided with an iris-diaphragm shutter between the source of light and the front glass, the leaves of the shutter are of crescent shape and are made of translucent material such as mica &c. to allow transmission of light from the source but to soften its intensity. The shutter is operated by Bowden-wire mechanism connected to a controlling-device, Fig. 4, mounted on the dash-board of the vehicle &c. The Bowden wire 14, one for each lamp, is connected to one end of a lever 17, against the other end of which bears the end of a spring-controlled plunger 16 slidably mounted in a casing 15<1> and prevented from rotating by the engagement of a pin 19 with a slot 20 therein.

Abstract: 635,616. Weighing-apparatus. AVERY, Ltd., W. T. Jan. 25, 1947, No. 2371. Convention date, Feb. 24, 1944. [Class 143] In a hydraulic weighing scale, the pressure receivers which reconvert the hydraulic pressure into force each comprise an internally and an externally stressed bellows unit connected in series mechanically, so that one acts through the other and errors due to variation in effective area are neutralised. A weigh platform 10, Fig. 1, is supported through swing links 15, on hydraulic capsules 17 which are each hydraulically connected, through a pipe 22, to an associated receiving unit 23 wherein the hydraulic pressure generated in each capsule is converted into mechanical force which is transmitted through a gathering lever 26 and a rod 29 to a counterbalancing weigh beam 31, Each receiver 23, Fig. 2, each has an externally stressed bellows 37, contained in a cup-shaped housing 39 which is secured to a base member 25 and is in hydraulic communication, through a hollow strut 46, with an internally stressed bellows 38 which is adjustably secured to the lever 26. The arrangement is such that errors due to the bellows 37 are cancelled by opposing errors in the bellows 38. An anchored link may be attached to the strut 46 to steady it. In Fig. 4 (not shown) this link is an adjustable blade spring by which mismatching of the bellows is corrected.

Abstract: 1,172,301. Frequency changing. ELIN-UNION A.G. FUR ELEKTRISCHE INDUSTRIE. 17 Jan., 1967 [25 Jan., 1966], No. 2508/67. Heading H2F. In a frequency changer for supplying an inductive heating load H, Fig. 1, comprising a winding a tuned by a. capacitor b, the current and voltage zero-crossings are sensed by detectors c and d with pulse shaping circuits A and B and used to control the timing of ignition pulses fed to thyristors in the inverter G which is supplied from a rectifier F. In this way the frequency of the inverter can be matched to the resonant frequency of the load, and the phase of the ignition pulses may be controlled by a counter-voltage time generator C to ensure maximum efficiency. Control circuit. Fig. 3. At a voltage zerocrossing of the output, negative pulses are applied at terminals 3 and 4 and change over the bi-stable circuit T5, T6 so that T6 blocks and T5 conducts, thereby blocking T7 and allowing C4 to charge through R18. At a current zero-crossing, i.e. a quarter-cycle later, negative pulses are applied at terminals 1 and 2 and change over the bi-stable circuits T5, T6 and T1, T2 so that T6 and T2 conduct. T3 is now conductive and charges C3 through a voltage-dependent resistance R5, the voltage across which corresponds to the voltage on C4. When C3 reaches the ignition voltage of unijunction transistor T4, the latter conducts and causes T9 to deliver an output pulse on line 10 and to restore the bi-stable circuits to their initial condition when T7 conducts and discharges C4. This cycle is then repeated. The output pulses are fed to the thyristors via an output circuit E, Fig. 1, which includes a bistable circuit (FF, Fig. 5, not shown); this is also supplied with pulses at the voltage zerocrossing times so that it remains in phase with the inverter if there is a fault in the control circuit. Automatic phase control.-The actual time for which counter-voltage is applied to the thyristors is detected by means not described and compared with the period of a monostable circuit (T11 and T12, Fig. 4, not shown), this period being manually adjustable. If the actual time is greater the voltage applied to terminal 6 in Fig. 3 is increased and if it is smaller an additional initial charge is added to C4 through terminal 5 (from terminal 21, Fig. 4, not shown), so that in either case an appropriate adjustment is made to the charging time of C3.

Jan. 25, 1935, No. 2575. [Classes 40 (iii) and 40 (v)] A source of high-frequency oscillations, such as a wireless aerial, is coupled to a receiver through a high-frequency cable in series with a phase-changing network, the overall electrical length of the cable and network being such as to cause the aerial to be tuned to the working frequency of the receiver. Fig. 3 shows an aerial 1 coupled through a high-frequency cable 3 to a phase-changing network constituted by a low-pass filter 4l, the receiver end of which may terminate in an inductance 4tl or a capacity to give a step-up transformer effect. Such a filter increases the overall electrical length of cable and network ; to decrease this length, a high-pass filter may be employed with similar alternative terminating impedances, Figs. 5 and 6 (not shown). An impedance-matching device 5 of a type known per se is provided between the filter network and the receiver as shown in Fig. 7. In all cases the network 4 is so designed that the total electrical length measured from the aerial end of the cable to the receiver end of 4 is slightly less than half the working wavelength or approximately one quarter wavelength, whereby the aerial is tuned to the working frequency by the load thrown back from the cable and filter circuit. In Fig. 8, the tuning controls G of the phase-changing network 4 and receiver 2 are unicontrolled and are remote from the aerial 1 and receiver to which they are connected through highfrequency cables 3a, 3b. The reproducer LS is also at the tuning station and is connected to the receiver through a similar cable LSC. Specification 448,779 is referred to.
