Title: A vehicle door lock
IPC: E05B77/06
Filed: 1969-03-05
Abstract: 1,219,234. Locks. DAIMLER BENZ A.G. 5 March, 1969 [6 March, 1968], No. 11749/69. Heading E2A. Accidental opening of a vehicle door on impact is prevented by an inertia-operated tumbler which blocks movement of the mechanism. In the form shown in Fig. 4, a lock mechanism between outer and inner door panels 1, 2 is operable by push-button 5 which moves an operating lever 4 and an angle-lever 6 blocking the rotatable locking member 7 against springs 8 and 9. An inertia mass 11 is carried on lever 10 which is normally biased against operating lever 4 by spring 12. An emergency acceleration 16 tending to open the door, drives the mass 11 in the reverse direction 17 so that lever 10 passes hard on the lever 4 to prevent opening movement of the mechanism. In the modification shown in Fig. 5, an inertia-operated lever 18 tilts so that its nose 21 blocks the opening movement of projection 22 on the operating lever 4 (Fig. 7, not shown).

Filed: 1942-08-29
Abstract: 562,855. Making soaps; soap powder. PROCTER & GAMBLE. CO. Aug. 29, 1942, No. 12209. Convention date, June 12, 1942. Addition to 555,034, [Group V]. [Class 91] Beta phase soap prepared by agitation of a mass of soap of appropriate composition within a temperature range, as defined in the parent Specification, is converted into powder while maintaining a temperature at which no substantial reversion of the beta phase to another phase takes place. The agitation operation may be combined with cooling and may be carried out within the narrower temperature range of which the upper limit is the highest temperature at which the soap will flow under gravity and the lower limit the temperature below which the soap loses its pasty consistency, e.g. from 160 F. to 115 F. The soap should contain at least 15 per cent of sodium soaps of saturated fatty acids containing from 16 to 22 carbon atoms per molecule, e.g. soaps of tallow fatty acids. Soap builders may be added and the soap may be aerated. As shown in the drawing, soap containing about 23 per cent moisture at 221 F. is passed into a crutcher 46 and thence into the cooling and agitating device 31, 42 constructed as described in the Parent Specification where the soap is cooled and agitated at about 122 F., at which temperature it has a soft pasty consistency and is well below its initial temperature. Compressed air may be introduced from a valve 22 and a soap builder, such as sodium silicate, may be supplied by a pump 54 and pipe 48. The warm mass is sprayed by compressed air admitted by a valve 52 to a nozzle 50 into a tower 51 where it meets and falls through an ascending column of air to be discharged in powder form from an outlet 53, the temperature at all later stages being kept below 160 F. The crutcher may be of the type described in U.S.A. Specifications 2,024,425 and 2,203,980 ; the agitating and cooling device of the type described in U.S.A. Specification 1,783,864; the spray-drying tower of the type described in U.S.A. Specification 1,985,987; and the atomising nozzle of the type described in U.S.A. Specification 1,472,473.

Abstract: 149,091. Denison, G. H., and Brown, S. G. May 17, 1919. Presses, cylinder-and-piston; pressure-producing apparatus.-In an hydraulic testing-machine, more particularly of the type described in Specification 121,013, for the purpose of testing springs, the passage-ways connecting the cylinder 4 to the pump 5 are made as short as possible by bolting the flanges 7, 8 of the pump ports directly to the port passages 9, 10 of the cylinder in order that the quantity of fluid in motion may be reduced to a minimum and thus reduce the surface friction and momentum so as to permit rapid reversals of flow of the pressure fluid. Air suction in the system is avoided by placing the supply tank 11 above the cylinder and pump, the usual relief and suction valves being enclosed in the tank. The pump may be driven by an electric motor 12 and controlled by means of a lever 6 in reach of the operator.

Abstract: 1,199,135. Transducers; indicators. VSI CORP. 10 March, 1969 [8 March, 1968], No. 12574/69. Heading G5R. A transducer having an operative area subject to erosion contains an indicator for indicating when the transducer has been eroded a predetermined amount. As shown, a screening can 11, containing two nylon half-sections 20 carrying half cores 13 and clamped together adjustably (Fig. 3, not shown), is drilled to receive a coloured epoxy filler 30 at a depth 27 below the working surface. The member 30 may extend across the gap 31, be sited immediately beside the cores to one side of the gap, may be located in the can 11 or sections 20, and may consist of two colours to show a colour change at the predetermined depth. Alternatively, a conductor buried in the sections 20 may be eroded to open an alarm circuit, or in the case of conductive records, two buried contacts may be bridged by the record. The depth 27 is chosen so that time (e.g. 40 hours) is available to change the transducer before it is totally useless.

It is fed forward by the pawl 42 which engages in notches b formed between each pair of tags a. The pawl 42 is pivoted on a pin 41 passing into a cylindrical block 40 and secured by a set-screw 45, the block 40 being mounted in a cylindrical hole in a member 28 forming part of the carriage 21 and secured in a position of adjustment according to the width of the strip of tags, by a spring- pressed sleeve 46, Fig. 4, mounted on the opposite end of the pin 41 and having projections adapted to engage in indentations in the side of the member 28. To feed tags of less than standard length, a cam plate 87, Fig. 16, is mounted on the plate 14 so as to raise the pawl 42 during a part of its stroke and thus decrease the effective feed stroke. A plate 12, Fig. 3, secured to a bracket 13 through which the strip passes on its way to the machine, is set at an angle to the strip so as to serve as a detent to prevent backward movement of the strip.
