Title: Improvements in or relating to gas ranges
IPC: F24C3/08
Filed: 1927-10-27
Abstract: 289,351. Jackson, L. Mellersh-, (Standard Gas Equipment Corporation). Oct. 27, 1927. Gas cooking-stoves; air supply for combustion; outlets to chimneys; burners, mounting and attaching. - A gas cooking-stove comprises in combination a closed hot-plate 3, a burner plate 18 beneath it and forming with it a shallow unobstructed combustion chamber 19 with vents 9 for the gases, a plurality of multiple-jet burners 26 located below the plate 18 and removable independently of it and of each other, and groups of openings 35 arranged in the plate 18 above the burner jets so as to form with them ejector devices entraining the secondary air. In the construction shown the burner nozzles terminate below the lower ends of the openings 35, which are formed in shallow dished portions of the plate 18. The front and sides of the combustion chamber are closed by the upturned edges 21, 22 of the plate 18, the rear edge of which rests on a sheet-metal outlet chamber or pocket 12 extending across the back of the stove and formed with a series of vents 9 through which the gases pass to a flue extending upwardly behind the splash-plate 6. The sides of the combustion chamber may alternalively be formed by a marginal flange extending entirely around it, the burner plate being suspended from the flange. The mixing-tubes 29 of the burners are supported on the gas nozzles in the usual manner, the rear ends of each burner being detachably suspended from the plate 18 by means of a thin upstanding lug 38, Fig. 4. Side wings 40 on the lug are passed up through a rectangular opening 43 in the plate 18, the burner being then moved forwardly to cause the wings 40 to rest on shoulders 44 at the front of the opening. Wings 41 at a lower level than the wings 40 engage the underside of the burner plate, and the burner is secured in position by a cotter pin 45 passing through an ear 39 formed on the lug 38 and extending through a slot 42 in the plate 18. The outlet flue is constructed of two sheet-metal sections having curved marginal portions 53, Figs. 3, 8, bent inwardly and secured in contact with one another, thus forming an upwardly-tapering flue of nozzle-like form, the base of which covers all the vents 9. A modified form of flue with straight upwardly and inwardly inclined side walls is described.

Title: Improvements relating to circuit arrangements for generating sawtooth voltages
Inventor: SCOLES GRAHAM JOHN
IPC: H03K4/12
Filed: 1951-12-06
Abstract: 731,159. Saw-tooth generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 22, 1952 [Dec. 6, 1951; Jan. 8, 1952], Nos. 28643/51 and 608/52. Class 40 (6). In a saw-tooth voltage generator of the type in which a capacitor is charged to generate the long flank and then discharged through a resistive circuit, the output is derived from a tapping on the resistive discharge circuit so that the output voltage falls to a lower value than that across the capacitor and circuits are provided to limit the minimum output voltage and the voltage to which the capacitor discharges. In Fig. 1 the capacitor C1 is charged through a resistor R1 and discharged through resistors R2, R3 and valve V1 when a timing pulse is fed to the grid of V1. The output is taken from the junction of R2 and R3 and fed through a resistor R4 to a cathode follower output valve V2. Adjustably biased diode D1 and D2 respectively limit the minimum voltage to which the capacitor discharges and the peak value of the negative output pulse during the flyback and due to the current through R2. The use of the by-pass capacitors C2, C3 may be avoided by replacing the diodes by triodes V3, V4 (Fig. 4) in which case the limiting is made more effective by using a voltage obtained from the anode resistor R6 when the clamping triode commences to conduct to reduce the current in the discharging valve VI. Alternatively the clamping valve V3 may be dispensed with and the grid of the first valve of cathode-coupled pair may be connected to the capacitor to provide a voltage at the output of the second valve which cuts off the discharging valve when the output voltage has fallen to the desired value (Fig. 5, not shown). Specification 621,752, [Group XL (b)], is referred to.

Title: Improvements in dental engine stands for supporting a dental engine of the type comprising a hand-piece and a pressure fluid operated motor carried by said hand-piece
IPC: B23B47/10
Filed: 1958-09-08
Abstract: 853,638 Dental stands. ATLAS COPCO A. B. Sept. 8, 1958 [Sept. 24, 1957], No. 28769/58. Class 81 (2) A dental handpiece of the fluid-driven type is carried on a stand and the arrangement is such that power is supplied to the tool only when the handpiece has been lifted from the stand. The invention is described with reference to the type of handpiece 7 which encloses an air-driven turbine and this, when not in use, is supported at one end of a lever 62. When the handpiece is lifted, the lever 62 is raised by a spring 64 and, through a rod 58, lifts a valve member 44 off its seating to allow air to flow to the pipe 57 and so to the turbine. Compressed air received through a pipe 10 is reduced in pressure on passing through a pressure control valve 14, controlled by an adjustable spring-loaded diaphragm 21 and then passes through the tubing 39 to the lever actuated valve 44 and so to a manually controlled check valve 51 to the handpiece. The manual valve 51 can be set as required and, thereafter, the supply of compressed air is dependent on the lifting and replacing of the handpiece on the lever 62. The opening of the valve 44 causes a reduction in pressure in the control valve chamber 20, with a resultant inward movement of the diaphragm 21, and this is communicated through the valve stem 15 to a micro-switch 31 which causes the water spray pump to be switched on, to supply water through a tube 79. This is then directed by a slide valve 70 to either of two tubes 80, 82, to supply water to whichever of the two handpieces is in use, the changeover of the valve 70 being effected by air pressure acting on the appropriate side of a piston 74 and supplied from the appropriate air line leading to the handpiece. Specification 785,109 is referred to.
