Patent GB-492453-A (GB)
Title: Improvements in odometers
IPC: G06M1/16
Filed: 1937-04-08
Abstract: 492,453. Transfer mechanism ; zercizing - mechanism. GENERAL MOTORS CORPORATION. April 8, 1937, No. 10008. Convention date, April 8, 1936. [Class 106 (i)] In a Geneva-type transfer mechanism, the locking ring 29 on each numeral wheel is provided with indentations 71, a gap 33 and two projecting transfer teeth 35, 37. The units wheel 13 is secured to the driving shaft 11. Alternate teeth 53 on the lower side of each transfer pinion are elongated and shaped to rest in locking engagement with the locking ring as shown in Fig. 3. Teeth 49 on the higher side of each transfer pinion engage teeth 27 on the next higher numeral wheel. The transfer pinions have central circumferential grooves in which engage horns 57 of fixed plates 39, the pinions being maintained in engagement by flat springs 61. The central shaft 11 is rotated for zeroizing in the reverse direction to normal and operates the wheels by a notch 65 engaging pawls 67 secured to the wheels. The transfer pinions can be rotated by the higher wheels during zeroizing because the teeth of the pinions bend the springs 61. On account of the indentations 71 the higher sides of the pinions are never disengaged from the numeral wheels, and thus all the numeral wheels retain their alignment during zeroizing and do not have to be moved to a position slightly beyond zero to allow for lost motion.

Title: Method of making fibreboard and the like
IPC: D21B1/12
Filed: 1965-03-10
Abstract: A process for improving the drainage properties of a suspension of fibres obtained from a raw material containing a proportion of bark and suitable for use in the production of fibreboard &c. comprises subjecting the suspension of liberated fibres to a heat treatment at 60 DEG -300 DEG C such that the solid content at the end of the treatment is 30 - 80% and for a sufficient length of time so that after dilution with water to a consistency suitable for sheet formation the drainage properties of the suspension are better by at least 5 Defibrator seconds-as defined in the specification-than those of a similar suspension which has not been given the heat treatment. The fibrous material may include the bark of spruce, pine, fir, birch, or aspen and also chips of these woods, waste material from pulp manufacture or from saw mills, and asbestos.  The treatment, which may be in one or more steps, is by hot air or steam at atmospheric or elevated pressures, and may be carried out before and/or after the fibrous material is refined.  In the particular example described the raw material is defibrated in the presence of steam, and blown in a steam suspension into a cyclone into which water at 60 DEG C was also introduced.  The fibrous material passes from the bottom of the cyclone on to a conveyor belt in a heat insulated casing for the heat treatment, and from thence into a stock bin for dilution.

Abstract: 610,481. Preserving food. SKINNER, C. D. April 8, 1946, No. 10754. Convention date, Sept. 27, 1945. [Class 49] [Also in Groups XIII, XXV, XXVIII and XXXV]. The air pressure inside a refrigerator is maintained above atmospheric pressure in order to prevent leakage of outside air into the refrigerator and to maintain the humidity within the refrigerator. Air is sucked from a storage chamber 6, past a cooling unit, by a solenoid operated pump 16, 19 which then ejects it under pressure together with an amount of air from the surrounding atmosphere into the chamber 6 by way of a pipe 24. A modification is described in which a normal motor-driven compressor is described. On operation of a door handle 7 the air inside the refrigerator is vented to relieve the pressure.

Title: Improvements in electric circuit arrangements for operating gas or vapour filled electric discharge lamps

Abstract: 730,373. Supply systems for spacs discharge apparatus.: GENERAL ELECTRIC CO., Ltd., COOPER, A. D., and NELSON, E. H. Aug. 1, 1952 [May 8, 1951], No. 10797/51. Class 38 (4). [Also in Group XL (a)] An electric circuit for operating a gas or vapour filled, e.g. H.P.M.V., discharge lamp 35 from a supply of lower voltage than that required to start the discharge but sufficient to maintain the discharge once started comprises an electromagnetic vibrator 46 whose make- and-break contacts 56, 57, serially connected with an inductance coil 45 across a supply, are automatically operated by energization and deenergization of such coil; while shunted across the contacts are serially-connected at least one capacitor 44, 52 and the primary winding 42 of a high voltage step-up transformer of which the secondary winding 40 is connected across the lamp starting electrodes, and a cut-out means is provided to render the vibrator inoperative when the lamp main discharge has started; for starting, the vibrator excites an oscillatory circuit formed by the primary winding and capacitors to generate high voltage H.F. oscillations which ionize the lamp discharge space. The cut-out means may comprise a switch or be automatic in operation upon starting of the lamp and comprise a slowly charged condenser or a relay energized by the discharge current, Figs. 1 . . . 3, not shown, or the contact 49 of a relay 50 whose coil 51 is energized by the volt drop across lamp ballast resistors 37 ... 39. The lamp starting electrodes may be the main electrodes 33<SP>1</SP>, 34<SP>1</SP> and the supply to the starting means and to the lamp may be the same. The transformer may be auto wound as shown, or double wound, and is, air-cored. Starting of the lamp may be facilitated by. the photo-cathode effect of a tungsten filament lamp 60 whose light causes electron emission from the cathode 33<SP>1</SP>. A rectifier 54 shunted across the vibrator is so poled that should a D.C. supply be connected to the circuit input terminals 31, 32 in incorrect polarity the vibrator is rendered inoperative and a lamp 48 provides an indication of the wrong connection. As shown, the lamp is enclosed in a housing 35<SP>1</SP> having a shutter 36 which is released for opening by a relay 75 when its coil 74 is energized through the contact 72 of a relay 62 whose coil 61 is in turn energized through a contact 64 of the relay 50 when the voltage across the resistors 37 ... 39 attains a value corresponding to normal operating current. Energization of relay 62 also de-energizes a relay 69 to put resistor 39 effectively in circuit to reduce the discharge current to a value suitable for when the shutter is closed; and opening of the shutter closes by mechanical means not shown a switch 67 to short resistors 38, 39 and run the lamp at the full operating current. Specification 653,131 is referred to.

Title: Improvements in or relating to bakers' products and sugar coatings therefor
IPC: A21D13/00
Filed: 1937-04-16
Abstract: Baked cereal products, e.g. cakes, biscuits, crackers, cookies, are coated with a sucrose or other sugar solution and then dusted with anhydrous dextrose.  The anhydrous dextrose extracts water from the solution in changing to hydrated dextrose, and, in consequence, effects a quick drying.  The coating is preferably applied in an inclined rotary tumbling pan, the cakes being first placed in the pan and, whilst being agitated, are coated with sucrose solution which is poured, sprayed or sprinkled into the pan.  The powdered anhydrous dextrose is then added and the tumbling continued.  A dry flavouring material, such as cocoa or chocolate, may be mixed with the anhydrous dextrose before introduction of the latter into the pan, or such material may be put in the pan before or after the dextrose.  Liquid flavours may be used, these being dehydrated by the action of the anhydrous dextrose.
