Title: Improvements in or relating to gas burners for heating and cooking purposes
IPC: F23D14/06
Filed: 1928-09-07
Abstract: 326,441. Bõrwolf, R. Sept. 7, 1928. Gas cooking-stoves. - The burner 8 of a gas cooking-stove is provided with a removable slotted top cover 17 which is employed when cooking, but may be removed to allow a vertical cone-shaped heating flame to be provided by a lower slotted member. In the construction shown in Fig. 1 the lower slotted member 20 is in the form of a hood surrounding an internal tubular part 18 of the burner. In a modification, shown in Fig. 6, the slits in the top cover 17 extend to the top surface of the cover, and the lower member consists of a slotted disc 19 resting on a tube 24. Fig. 6 shows a further modification in which, upon removal of the slotted top cover 17, a vertical flame is produced by the mixture issuing through slots 22 in two superposed discs 19, 25, the lower of which has a depending core-piece for directing the mixture to the slots. The burner 8 shown in Fig. 1 is mounted in a central aperture in a bearer 3 by means of a bayonet joint comprising projections 8<b> on the burner which pass through slots 13 after the burner has been turned. The bearer 3 is pivotally supported at one end in a bracket 9, and at the other by means of a tubular member 2 which receives a ball end 4 on the bearer. By removing the pivot pin 10 the bearer may be withdrawn. The gas supply pipe 11 and tap 6 are detachably held by an extension 5 which enters the member 2, and by engagement with the bracket 9. In a modification the burner is held by a similar bayonet joint in an aperture plate supported by downward extensions of utensil-supporting ribs.

Title: Transistor ring counter
IPC: H03K23/00
Filed: 1955-09-09
Abstract: 780,395. Transistor pulse generating and frequency dividing circuits. HAZELTINE CORPORATION. Sept. 9, 1955 [Oct. 6, 1954], No. 25860/55. Class 40 (6). In a counter-type circuit each transistor in the chain is coupled to the next with the last coupled back to the first over an astable generator, clock pulses being supplied to each stage to tend to render them non-conducting so that a single stage is conducting and the conductivity is progressed around the chain. The relaxation oscillator 90 is such that when freerunning the emitter potential would vary according to curve A. When the emitter potential falls, a corresponding collector pulse C is generated and fed over transformer 95 and differentiating circuit 101, 102 to produce the waveform D. Due to the diode 103 only the negative-going pulse E is fed to the base of point contact transistor 11 which triggers into the conducting state, generating a positivegoing pulse F at the collector. This pulse is terminated by the next positive-going control pulse B fed in at terminals 80. In a similar manner the pulse F is differentiated and the negative-going pulse G is fed to the base of transistor 21 to trigger it into the conducting state. In this manner pulses H, J, L, are made available at the collectors of transistors 21, 31 and 41. The pulse L is differentiated by circuit 81, 82 to give waveform M the negativegoing trailing edge being effected over diode 83 to re-set oscillator 90 which recommences a cycle according to curve A<SP>1</SP>. If when the circuit is put into operation two or more stages are conducting, spurious pulses n will be fed back to the oscillator 90 but are ineffective to re-set the circuit.

Class 106(5) A liquid dose dispensing apparatus comprises a storage reservoir 1, means for displacing liquid from the reservoir, and means for dispensing the liquid so displaced in predetermined measured quantities, the means for dispensing the liquid being constituted by a dosing chamber 2 communicating with the interior of the reservoir through a duct 3 having one end disposed at a predetermined height above the bottom of the chamber 2. The walls of the reservoir 1 are deformed by the fingers of the user's hand to displace liquid through the duct 3 into the chamber 2. As soon as the pressure of the fingers is released the liquid in the chamber 2 falls to the level of the top of the duct 3 and the measured quantity thus obtained may be poured out by tilting the apparatus. The chamber 2 may have a screwed connection with the reservoir 1 or it may be formed integrally therewith. In a second embodiment, the apparatus is turned from the position shown in Fig. 3 until it rests on the wall 11' and a measured quantity introduced into the chamber 13 as before. The apparatus is then restored to the position shown and the walls of the reservoir again deformed to produce an increased internal pressure which 'is communicated through the tube 14 to the chamber 13 so that the measured quantity of liquid is ejected through a tube 15. The upper end of the tube 14 may be curved back on itself to prevent an appreciable quantity of liquid from being transferred from the tube to the chamber when the apparatus is returned to dispensing position. A pump or a deformable bulb may be used to effect the displacement of the liauid into the dosing chamber which may be located inside the reservoir.
