Title: Improvements in or relating to electrical generator regulating systems especially for mechanically propelled vehicles
IPC: H02J7/24
Filed: 1958-05-01
Abstract: 887,407. Automatic voltage-control systems. BOSCH G.m.b.H., ROBERT. May 1, 1958 [May 2, 1957], No. 74/60. Divided out of 887,405. Class 38 (4). In an automatic voltage regulator for a shunt exciter D.C. generator of the kind in which a transistor is in series with the field winding, the transistor is controlled by a Hall generator responsive to the output voltage and current of the machine to give a compound characteristic generator G having a field F supplies a battery over a rectifier D2 (which replaces the cut-out). The field F is in series with a transistor T2 which forms a blocking oscillator with the field F and a capacitor 40. The magnitude of the current pulses is controlled by a Hall generator 43 in the base circuit, the impedance of the Hall generator being controlled by an electromagnet 44. The electromagnet 44 has a voltage coil 45 in series with a Zener diode D1 across the output of the generator G, and a current coil 46, opposing the voltage coil 45 connected in series with a diode D4 across a resistor R5 in series with the load. The diode D4 is either of the kind having a pronounced kink in its forward characteristic, or is a Zener diode, in which case it would be connected in the opposite direction to that shown.
Patent JP-S60144879-A (JP)
Title: Bar code recorder
Inventor: OONUMA TERUYUKI
IPC: G06K1/12
Filed: 1984-01-05
Abstract: PURPOSE:To attain the uniform recording with a device which records bar codes by applying the signal voltage to a recording head containing two flat plate type electrodes and then pressing the head to an ink sheet and an object to be recorded, by reducing the width of an ink layer less than the width of the electrode. CONSTITUTION:Two flat plate type electrodes 2 and 3 are set with an insulated spacer 1 put between both electrodes to constitute a recording head. An ink sheet 5 consists of a base layer and an ink layer 7 and is pressed to a recording head together with a recording paper 8 by a platen roll. Then the signal voltage is impressed between both electrodes 2 and 3, and a current flows to the sheet 5. Then the layer 7 between both electrodes 2 and 3 is fused by the Joule heat generated by the current. Thus the bar codes are transcribed and recorded to the paper 8. If the width (w) of the layer 7 is larger than the width W of electrodes 2 and 3, the current detours around both ends of the electrode. As a result, a recorded bar code pattern has a line having swells at both ends and therefore the ink density is easily reduced at both ends of said pattern line. Therefore the width (w) is set smaller than the width W in order to prevent the defect.

Patent GB-762656-A (GB)
Title: Improvements in or relating to the production of dieneones
Inventor: CARROLL MICHAEL FRANCIS
IPC: C07C49/20
Filed: 1953-01-02
Abstract: Dieneones are produced by heating acetylenic carbinols having the formula R1R2C(OH).C­ CH, in which R1 and R2 are the same or different and either one may be hydrogen, an alkyl or alkenyl, an aryl or aralkyl group, with a b -keto carboxylic acid ester having at least one hydrogen atom on the carbon adjacent the carbonyl group and thereafter heating the alcoholysis product so formed in the absence of catalysts; the course of the reaction being observed by the evolution of carbon dioxide.  In a modification, the acetylenic carbinol may be reacted with diketene or a diketene adduct of the type described in Specification 749,749, in the presence of an acid or mild alkaline catalyst to produce the intermediate acetoacetate which is then heated to form the dieneone, after neutralizing the catalyst.  In the case where an acyl acetic ester is used it is preferred to heat together the reaction components under reflux in the presence of a solvent such as toluene or m-xylene; the alcohol formed is distilled off together with the solvent and the second stage of heating is then continued under reflux.  In the case where diketene or a diketene adduct is used, the reaction components are preferably first reacted at atmospheric temperature in the presence of a small amount of an acid or preferably a mild alkaline catalyst, e.g. 0.1 per cent triethanolamine, and then refluxed after neutralizing the catalyst and, when a diketene adduct is used, after distillation of the ketone and unchanged reagents.  The course of reaction in either case may be followed by measuring the amount of carbon dioxide evolved and it is preferred to stop the reaction before completion to avoid polymerization.  A suitable antioxidant such as catechol or diphenylamine may be added.  The product may be isolated by fractional distillation or crystallization.  According to examples: (1) phenyl methyl ethinyl carbinol, ethyl acetoacetate and toluene are heated in a soda-free glass flask until most of the alcohol formed has distilled off, the residue is heated up to 170 DEG C. for 6 hours and the product is washed with dilute alkali and vacuum distilled to give C6H5C(CH3)=CH.CH=CH.CO.CH3 characterized as its oxime; (2) dehydrolinalool, methyl acetoacetate and toluene are treated as in (1) and the product on vacuum distillation gives pseudo ionone which may be cyclized with phosphoric acid to a - or b -ionone; (3) phenyl ethinyl carbinol, diketene and p-toluenesulphonic acid are allowed to stand until the odour of diketene disappears, the catalyst is neutralised, and the product is mixed with m-xylene and refluxed giving on vacuum distillation cinnamal acetone; (4) phenyl methyl ethinyl carbinol, the acetone adduct of diketene, and toluene are heated together with 0.1 per cent triethanolamine as in (1) and when the acetone has been disilled off the residual ester is pyrolysed and the dieneone recovered as in (1).  Reference has been directed by the Comptroller to Specification 733,884.

Title: A New or Improved Reeling Machine especially Applicable for Laying Sheeting on a Cricket Pitch.
Inventor: TRICK WILLIAM DAVID
IPC: A63C19/12
Filed: 1919-01-03
Abstract: 124,409. Trick, W. D. Jan. 3, 1919. Protecting cricket pitches.-A reeling machine for laying down and taking up a waterproof sheeting for a cricket pitch comprises a drum d mounted upon a trolly a. The sheet is laid by first pinning one end f to the ground and then running the trolly along so as to unroll the sheet. To rewind the sheet, one end o of a cord m which makes one turn round the drum d is pinned to the ground, and the trolly is run back to its starting point, the action of the cord on the drum producing the necessary rewinding. During unwinding of the sheet, the end n of the cord is secured to the end f of the sheeting. The sheeting is detachably secured to the drum by means of a strip fitting into a longitudinal groove in the drum, thereby permitting the trolly to be removed without the sheet for use elsewhere
Patent GB-932394-A (GB)
Title: Electro-catalytic gas igniters
IPC: F23Q13/00
Filed: 1961-01-03
Abstract: <PICT:0932394/III/1> A hydrogen-generating cartridge 12 adapted to supply through a tube 2 a puff of hydrogen to an ignition device for a gas burner (see Group XI), comprises a bellows 15 normally expanded by the hydrogen gas pressure so that an end plate 16 contacts a porous plate 17 covering a water chamber 18.  When, on operation of the burner ignition device (not shown), the hydrogen pressure falls, the bellows contracts and hence permits air to percolate through plate 17 and this ultimately causes water to trickle through a pipe 19 into a calcium hydride bed 21 thus generating more hydrogen which passes through a tube 22 containing a non-return device 23, into the bellows chamber 15 until the bellows expands to cover the plate 17 and hence prevent further generation of hydrogen until required. Specification 932,394 is referred to.
