Title: Improvements in internal combustion engines
IPC: F02F1/36
Filed: 1924-05-26
Abstract: 238,933. Kirke, P. St. G. May 26,1924. Cylinders, liners for and cooling.-To reduce the output of the engine of a Ford motor-car each cylinder is fitted with a liner e having a flange o and with means to alter correspondingly the compression ratio. The flange o may be accommodated by packing between the head and the cylinder, and the compression space may be reduced by lengthening the piston or providing a new head g having a recess to accommodate the flange o; the new liner and head may, however, be integral. Fluid-tight gaskets are provided at r<2>, r<3>, r'. The liner may be water-cooled by leaving a space m and causing the water to circulate in the direction of the arrows by providing two ribs n and a number of corresponding holes in the flange o and the head; a packing l renders the space m water-tight. If the liner and head are made integral, the liner may have a space cast in it for the cooling water. The end liner may be cut away at w to enable it to passthe car framing x and be inserted without removing the engine.

Title: Preventing the locking of vehicle wheels during braking
IPC: B60T8/42
Filed: 1971-05-04
Abstract: 1347033 Antilock braking systems D BLIESENER 4 May 1971 [4 May 1970 22 Feb 1971] 12947/71 Heading F2F In an antilock brake system voltage signals U B , U M  respectively representative of rate of change of pressure in the wheel's brake cylinder and rate of change of frictional force between the wheel and a road surface control operation of a solenoid valve between a pressure source and wheel cylinder to prevent wheel-lock. A circuit is closed on commencement of the braking by a switch 2 and voltages U B  and U M  are respectively fed to the primary coils of transformers 4, 6 and 5, 7 to induce a voltage corresponding to the rate of change of U B  and U M  in the secondary coils. Transformers 4, 5, 6, 7 are connected in series to amplifiers 8, 9, 10, 11 of which 8, 9 amplify voltages induced with voltages U B  and U M  rising, 10 amplifies the induced voltage when U B  declines and 11 amplifies every voltage induced by U M . If the wheel cylinder pressure rises while the frictional force declines or remains constant, or if the wheel cylinder pressure remains constant while the frictional force drops the circuit to coil 3 of a solenoid valve is closed through the amplified induction voltages and switches 12, 13, 14, 15. Coil 3 causes a chamber 9<SP>1</SP> of a modulating device to be connected to the engine intake manifold causing movement of a diaphragm 10<SP>1</SP> and piston 11<SP>1</SP> to open a one way valve 14<SP>1</SP> and cause pressure to act on a differential piston 1<SP>1</SP> to close communication between the pressure source and wheel cylinder through passages 2<SP>1</SP>, 4<SP>1</SP>, and close a non-return valve. After the termination of lock piston 11<SP>1</SP> is released and fluid in the wheel cylinder passes to the pressure source through one way valve 8<SP>1</SP>. The wheel cylinder pressure and friction force are measured piezo-electrically or by extensometer strips. The fluid may be liquid or compressed air. The friction force may be measured directly or may be determined indirectional from the horizontal reaction force between the wheel and road or the horizontal reaction force acting on the wheel bearing or the horizontal bending moment on the wheel suspension.

Title: Improvements in and relating to the coating of aluminium surfaces with metal
IPC: C23C4/02
Filed: 1937-05-18
Abstract: To prepare an aluminium surface for spraying a coating or filling of metal thereon, the surface is cleaned by means of an abrasive, coated with silver, and then rubbed with a coating composition comprising mercury, mercury bichloride or borax, copper sulphate, zinc chloride, hydrochloric acid, and an abrasive.  The silvering is preferably effected by brushing with a silver nitrate solution containing nitric acid in an amount less than 1 per cent by weight.  The coating composition, which produces on the silvered surface a bright coating containing copper, mercury, and zinc, is prepared in two parts, one being a powder comprising the mercury, the bichloride of mercury or borax, and the abrasive, the latter preferably a mixture of quartz sand and the abrasive known under the Registered Trade Mark "Crystolon," and the other part being a solution of the copper sulphate, the zinc chloride, and the hydrochloric acid.  The two parts are mixed together to form a thick paste and left for at least 12 hours before use, the paste being then applied with a wooden paddle and rubbed on with a felt pad.  Any excess of the coating composition is removed and the prepared surface is then sprayed in the manner described in Specification 491,173, preferably by the use of the spray gun described in Specification 491,172, [Group XXIX]. The process is described with reference to the filling of dents or depressions in an aluminium motor-car body by spraying a filling of lead or lead alloy, the surface being first ground and then prepared and sprayed as described, the sprayed metal being deposited evenly over the depression and slightly beyond the edge thereof and then ground down.  The sprayed surface and any surrounding parts with which the silvering solution or the coating composition has come in contact may then be cleaned, e.g. with caustic soda, and painted, for example by spraying.

Title: Circuit arrangement for voltage regulation in charging devices for electric accumulators
Inventor: HIRSCHMANN RICHARD
IPC: H02J7/00
Filed: 1968-03-21
Abstract: 1,212,588. Charging batteries. R. HIRSCHMANN. 21 March, 1968 [23 March, 1967], No. 13765/68. Heading H2H. In a device for charging accumulators, the charging current flows through the collectoremitter path of a transistor. When the accumulator is fully charged, current is able to flow through a Zener diode and a second transistor arranged in such a way that the first transistor ceases to be conductive, so stopping the charging process. An accumulator A is charged through a resistance R 1  and a transistor T 1 . During charging, the base of the transistor T 1  is kept at a voltage U 1  derived from a potentiometer R 2 R 3  and stabilized by a Zener diode Z 1 . The voltage U 1  is greater than the maximum value of the accumulator voltage U A . When U A  reaches this maximum voltage, a second Zener diode Z 2  connected to a potentiometer R 4 , is arranged to break down and feed current to the base of a second transistor T 2 . A current can now flow through the collector-emitter path of the transistor T 2  and through a resistance R 6 , which has the effect of lowering the voltage at the base of the first transistor T 1  at least to the value of the accumulator voltage so that charging through the transistor T 1  is stopped. A resistance R 7 , connected across the transistor T 1 , allows a very low charging current to pass in order to compensate for leakage from the fully charged accumulator. A condenser C 1  or C 2  may be included in the circuit in order to ensure that the initial current flows through the transistor T 1  rather than through T 2 , and the resistance R 1  may include an indicating glow lamp.

Cases combined with safety razors; fittings, internal; contents, delivering. -The handle of a safety razor serves as a magazine for a number of blades 17 inserted singly or stacked in a clip 18 such as is described in Specification 264,203. A spring 20 bears against the blades, urging them to the right into contact with a slider 26 normally held in the handle by a member 31 secured to the slider and frictionally engaging the handle. The spring has a bent out portion 22 retaining the clip 18 in position, a tongue 23 by which it may be withdrawn, together with the empty clip, and a retaining perforation engaging a projection 25. By pulling out the slider 26, Fig. 3, and returning it, its movement being limited by pins 31 and slots 32, a tongue 28 on the slider projects the blades singly through a slit 30 into a slit 16 in a combined blade-holder and guard, when the holder, which is pivoted to an extension of the handle, is placed parallel to the handle as in full lines, Fig. 1. For shaving, the holder is rotated to the dotted line position 14. In the full-line position the holder may be covered bv a cap 13<a>. The tongue 28 normally closes the slit 30 to prevent ingress of water &c. to the stacked blades, and the clip has a tongue 33 which overlies the tongue 28 in the outermost position of the slider to ensure absence of obstruction to the return movement. When the clip is emptied it is engaged by, and can be withdrawn by means of, the spring 20. Spring and clip are withdrawn or inserted through an opening in member 34 normally closed by a screw cup 38.

Title: Synchromesh device for the reverse gear of a motor vehicle  gearbox
IPC: F16H3/38
Filed: 1974-03-29
Abstract: 1461328 Change speed control FORD MOTOR CO Ltd 29 March 1974 [17 April 1973] 13943/74 Heading F2D In a motor vehicle countershaft gear wherein four forward ratios and one reverse are selected by a shift lever movable in a three channel gate to operate a single slide-turn selector rod 2, the gear input shaft is decelerated to facilitate meshing of the reverse sliding wheel at standstill, by engagement of a pin 11 on the selector rod 2 with one inclined side of a notch 12 in the 3-4 shift fork 4 which, when the selector rod 2 is turned to preselect the reverse channel, is thereby shifted axially against disc springs 8 by a limited amount sufficient to engage the friction synchronizing ring of the fourth ratio, the ring being subsequently released by axial retraction of the pin 11 when reverse is established. For this purpose the 3-4 shift fork 4 has limited axial freedom with respect to an arm 6 through which it is moved axially by the usual selector finger 3 on the rod 2 and is prevented from rotation by a projection 10 engaging the arm. During preselection of the reverse channel the arm 6 is locked by the usual interlock and the shift fork 4 is moved axially to the synchronizing position against the disc springs 8. When the selector shaft 2 is turned to preselect the 1-2 channel the pin 11 aligns with a deeper axial portion of the notch 12, which it enters for second and moves away from for first, which ratios are thus unaffected. In the 3-4 channel the pin 11 is turned into engagement with a flat part of the notch 12 opposite the inclined part, thereby locking the 3-4 shift fork 4 to the selector rod 2 for normal 3-4 selection.
