IPC: H02P9/00
Filed: 1932-11-14
Abstract: 398,365. Systems for transmitting mechanical power. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Nov. 14, 1932, No. 32148. Convention date, Nov. 24, 1931. [Class 38 (iv).] A Diesel-electric vehicle has the generator excitation varied by a fluid-operated resistance 4<1> controlled in accordance with the vehicle speed to keep the engine output constant, and by the Diesel engine speed governor. The motor current energizes a relay 10 which admits fluid pressure to a cylinder to actuate a piston 7 varying the resistance 4<1> and connected to an arm 13 pivoted at 21 and connected to a piston 9 which moves to close the ports in a relay actuated sleeve 8. An additional lever 14 pivoted at 20 is power controlled by the engine governor 17 and also adjusts the position of the resistance 41 but in accordance with the engine speed. The position of the pivot 20 is power adjusted from the driver's seat to control the setting of the engine governor and the regulator 4<1>. The engine governor also controls fuel supply. The sleeve 8 of the control valve may be operated by a speed governor driven directly from the driving-axle or by an electromagnet-energized in accordance with the generator_voltage.

Title: Improvements in or relating to stop watches
Inventor: HABGOOD JAMES GEORGE
IPC: G04F7/06
Filed: 1960-09-19
Abstract: 994,871. Watches. S. SMITH & SONS (ENGLAND) Ltd. Sept. 19,1961 [Sept. 19,1960], No.32175/60, Heading G3T. A stop watch of the kind in which three successive depressions and releases of a control button 29 step-on a cam device in the form of a turreted ratchet wheel 26, so that (a) the first step actuates a follower 22 on a lever 20 to carry a resilient stop pin 19 on the lever, which pin is initially in contact with the balance at a position A, along with the balance to start it before moving clear of it to a position B, whereby the seconds hand is started; (b) the second step actuates the follower so that it moves the stop pin from position B back into contact with the balance at position A to arrest it along with the seconds hand; and (c) the third step (by means not shown) releases the seconds hand for return to zero by a spring, is characterized by guard means 17 which prevents the pin 19 from re-engaging the balance until step (b) is substantially ended. The invention avoids the possibility of fictitious low readings being obtained owing to an arrest of the balance by a partial depression only if the button 29 during a timing operation. As shown, the guard 17 is constituted by an upstanding rib on an arm 16 carried from a bridge 13 which supports the balance arbor. A spring biased detent 35 locates the turreted ratchet wheel 26 in the initial position, this detent being moved out of the space between the turret cam projections 25 to engage the projectors frictionally. Reverse movement of the ratchet is prevented by a pawl 31.
Patent GB-322806-A (GB)
Abstract: 322,806. Valentine, H. J. Sept. 12, 1928. Preserving flowers, foliage, &c.-Flowers, foliage, &c. are preserved and retained in their natural shape by applying a coating of a waxy material having a suitable melting point and a coating of a suitable colloid such as gelatine or albumen, a binding coating e.g. a varnish or emulsion, being interposed between the waxy and colloidal coatings. The waxy material may be a paraffin wax, suitably that with a melting point of 45-50‹ C., or beeswax, or a mixture of paraffin wax and beeswax. The colloidal coating may be treated with formaldehyde or other hardening agents. Loading materials, such as zinc oxide or barytes, or dyes or pigments may be added to any or all of the coatings and may be supplemented by the local application of colour by hand. A preservative, e.g. camphor, boric acid or salicyclic acid, may be incorporated in one of or both the waxy and colloidal coatings. Before treatment, the materials, which may be dried, may be treated with alcohol which may contain a preservative with an acid reaction when the colour of the material is red to pink and one with an alkaline reaction when the colour ranges from blue to white. In an example, daffodils are treated first with a solution containing 80 parts by weight of methylated spirits, 10 parts of boric acid and 10 parts of rosin. After the superfluous solution has been removed and the coating has dried, a coating comprising 8 parts of paraffin wax and 2 parts of beeswax and having a melting point not exceeding 50‹ C. is applied. When this has solidified, a solution consisting of 20 parts of methylated spirits, 20 parts of ether and 1 part of rosin is applied to act as a binder between the wax coating and a final colloidal coating obtained by dipping in a solution of 1 part of gelatine in 3 parts of water. A final waterproof coating, e.g. of celluloid or rubber, may be added. All the coatings may be applied by spraying, dipping, brushing on, &c. The gelatinous or other coating may be built up by applying- several thin layers. The Provisional Specification describes the application to the materials of a protective coating of a colloidal nature or emulsion of a gum, albumen, &c. to which a preservative may be added, prior to the addition of the wax coating.

Filed: 1962-08-22
Abstract: 972,030. Control systems for A.C. loads. O. EVANS. (Robotron Corporation). Aug. 22, 1962, No. 32326/62. Heading H2H. [Also in Division H3l A switching circuit comprises a pair of semiconductor controlled rectifiers connected in inverse parallel relationship between a pair of A.C. supply terminals, first supply means for applying a trigger potential on to the gate of one rectifier, and a second supply means operable when that rectifier becomes non-conducting to supply a trigger potential to the gate of the other rectifier. As described, an A.C. supply is connected across lines 1, 2, and the next positive pulse on line 1 after closure of the switch 9 causes the rectifier 7 to conduct, so that the pulse is fed via transformer 4 to the output line A, B. At the termination of this pulse, the field in transformer 4 collapses and induces a pulse in winding 17 which switches on rectifier 13 at the same time as a positive pulse appears on line 2. Current therefore flows through the rectifier 13 and a reverse pulse appears at output A, B. When the next positive pulse appears on line 1, the cycle will repeat if switch 9 is still closed. If switch 9 is opened, no gate pulse appears on rectifier 7, and it does not conduct, and no trigger pulse is produced for rectifier 13. The switch 9 may be manual, mechanical, electric or may be an electronic circuit.
