Title: Vehicle door locking or fastening systems
IPC: E05B65/36
Filed: 1975-06-26
Abstract: 1517721 Locks WILMOT-BREEDEN Ltd 3 March 1976 [26 June 1975] 27140/75 Heading E2A Vehicle door latches are locked and unlocked or shot and retracted by electromagnets fed with pulses of current which are widely spaced to reduce heating of the electromagnet coils. As shown in Fig. 1, latch bolt solenoids 510, 511, 512 and 513 on the respective doors of the vehicle are double-wound to move the bolts to and from their fastening positions under the control of an individual door switch P12 or P13 operable by the sill button or an outside key-lock, or a dashboard switch CS1. These controls are connected to fastening and releasing relays 15, 16 through a control unit 14. Relays 15, 16 also control a boot-lid fastening mechanism at B5. The various control switches are of the two way form shown at 5 in Fig. 2, to provide the separate fastening and releasing functions. Generators AC provide trains of pulses to the operating coils through relays R. The pulses may be a tenth of a second during each second. A transistor circuit involving two monostable elements and a Darlington pair circuit is also described for producing the same effect.

Abstract: 246,938. Amalgamated Dental Co., Ltd., (formerly Ash, Sons & Co., Ltd., C.), and Weller, F. W. Nov. 13, 1924. Inhalers.-In a device wherein a valve 13 is opened by a pull applied to a toggle lever system which is connected to the valve stem, the end links are formed with eccentric portions 22a which abut against a member secured to a tubular casing 10 enclosing the valve stem 15 and providing a seating for the valve. The abutment consists of a bridge-piece 23 surrounding the tubular casing 10 and two vertical sides 24, 25 provided at their upper ends with lugs 26, 27 sliding in channels 28, 29 in the tubular member and is adjusted and secured in position by nuts 30, 32. The valve stem 15 passes through a gland 20 and screws into a socket 21 to which the toggle levers 22 are attached by a pin 22<1>. To the other end of the toggle lever system is adjustably secured a wire 36 passing around a pulley carrying a pedal lever whereby the valve is operated. The pressure of the valve against its seating is varied by means of a screw plug 19 acting on the valve spring 18. The valve is suitable for controlling the flow of gas for anaesthetic purposes from cylinders (not shown) hung on arms 7, 8 of a vertical pillar 6 on a short arm of which the tubular member 10 is secured. A handle 9 serves for transporting the apparatus.

IPC: C07D487/04
Filed: 1945-10-17
Abstract: 1-Substituted 2 : 5-diketo-7-methylpyrimidopyrazoles, of the general formula <FORM:0599891/IV/1> (wherein R represents alkyl, e.g. methyl, ethyl, propyl, butyl, octyl, decyl, octadecyl or other alkyl radical containing up to 24 carbon atoms, aryl, e.g. phenyl, naphthyl, anthranyl or diphenyl, aralkyl, e.g. benzyl, methylbenzyl or ethylbenzyl, or a heterocyclic radical, e.g. benzothiazolyl, a -quinolyl or a -pyridyl, the alkyl, aryl and aralkyl groups being optionally substituted by halogen, e.g. chlorine, bromine or iodine, amino, substituted amino, e.g. mono- or di-methyl- or -phenyl-amino, sulphamino, or solubilizing groups such as sulphonic or carboxylic acid groups) are manufactured by heating a corresponding 1-substituted 3-amino -5-pyrazolone with diketene.  The reaction is advantageously carried out at 75-130 DEG  C. in a solvent-diluent, e.g. a cyclic hydrocarbon such as cyclohexane, cycloheptane, cyclo-octane, benzene, toluene, o-, m- or p-xylene, ethylbenzene, 1 : 2 : 4-trimethylbenzene, propylbenzene or 1 : 3-ethylmethylbenzene or an oxygenated hydrocarbon such as ethyl methyl ketone, diethyl ketone, methyl propyl ketone, allylacetone, mesityl oxide or dioxane, or at 80-100 DEG  C. in aqueous suspension. The reactants are preferably employed in the proportion of 1-1 1/2 molecular proportions of diketene to one of the pyrazolene derivative, the optimum ratio being about 1.2 : 1.  The products are useful as colour-formers for the production of blue dye images in colour photography by colour-forming development, for which purpose they are advantageously rendered fast to diffusion in gelatin by introducing, as the group represented by R, substituents of the types described in Specifications 458,400, 465,823, 479,838, [all in Group XX], 483,000, 484,698, 489,161, 489,274 and 491,958.  In examples: (1) 1-phenyl-3-amino-5-pyrazolone is heated with diketene in xylene to produce 1 - phenyl - 2 : 5 - diketo - 7 - methylpyrimidopyrazole; (2) 1 - p - tolyl - 3 - amino - 5 - pyrazolone similarly yields 1-p-tolyl-2 : 5-diketo-7-methylpyrimidopyrazole; (3) 1-a -quinolyl-3-amino-5-pyrazolone similarly gives 1-a -quinolyl-2 : 5-diketo-7-methylpyrimidopyrazole.  Reference is also made to the production of 1-methyl-, 1-ethyl-, 1-propyl-, 1-o-tolyl, 1-(21-benzothiazolyl)- and 1-a -pyridyl-2 : 5-diketo-7-methyl pyrimidopyrazole, and to the use, as starting materials, of 1-b -naphthyl- and 1-p-chlorophenyl-3-amino-5-pyrazolone.

The diodes 22, 24 are diffused junction diodes comprising respectively P-regions 84, 86 and N-regions 88, 90 formed therein. The load impedance 26 is formed as a MOSFET whose drain is a P-type region 64 and is connected directly to the gate electrode 68, and whose source is constituted by the P-region 52 which also forms the drain of transistor 10. The amplifier of Fig. 3 may be the first of several stages of amplification; the second being, for example, a similar amplifier having two pairs of parallel reverse connected diodes (146, 148, 150, 152, Fig. 4, not shown), and the third being also similar but having two series opposed diodes (172, 174); the output stage includes a breakdown diode (184) connected to a MOS load impedance (180) from the junction of which components is connected a source follower (188) having a further MOS load impedance (192) in the source circuit. Alternatively, the second stage (Fig. 5, not shown) may be a directly connected MOSFET (206) having a MOS load impedance (214) and having its drain connected to a source follower (240) with a MOS load impedance (244).

Abstract: 734,169. Water-tube steam boilers; vertical steam boilers; steam boilers without internal flues. AKTIEBOLAGET SVENSKA MASKINVERKEN. Oct. 7, 1953 [Oct. 20, 1952], No. 27581/53. Class 123 (2). A steam boiler comprises a cylindrical vessel 10 mounted in a casing 16 above a combustion chamber 14, the vessel having a top steam outlet 19 and a feed pipe 12 through which water can be supplied to maintain a level 11 in the vessel. To effect a rapid transfer of heat from the gases passing upwardly around the vessel from chamber 14 to a top outlet 17, a large number of rods 18 are welded to the outside surface of the vessel below level 11 to extend radially therefrom to within a small distance of the casing 16. In operation, steam is generated rapidly on the interior surface of the vessel and rises thereover to issue from the water surface with a minimum of disturbance thereof, substantially dry steam being withdrawn at 19. As shown for example in Figs. 3 and 7, increased capacity is obtained by combining a number of vessels such as 10 in a single unit. Thus in Fig. 3, vessels 25, 26 and 31 are connected at their bottoms to a header 27 and extend upwardly around a combustion chamber 39 to a steam header 48. Three rows of shorter vessels 42, 43, 44 are disposed above chamber 39 and are likewise connected between headers 27 and 48. To avoid level fluctuation the vessels are interconnected at the working level 54 and connected to a compensating drum 58<SP>1</SP> by pipes 57. A downcomer 58 connects drum 58<SP>1</SP> and header 27. The furnace gases pass upwardly around the vessels and discharge through a downpass 56 locating an economizer 61 through which water is supplied to drum 58<SP>1</SP>. As shown in Fig. 7, vessels 65 are connected between a lower header 66 and a steam header 67, the combustion chamber 68, which is located alongside the group of vessels, being defined by two sets of water tubes 69 and 70 also connected between the headers. The gases from chamber 68 flow through a pass 74 locating a superheater 75 and then pass upwardly around the vessels and through a flue 77 in which is disposed an economizer 78. The vessels are interconnected at the water level by ducts 81 and through header 82 and downcomer 83 to header 66. Specifications 661,909, 673,721, [Group XXII], and 715,611 are referred to.
