Title: Improvements in steering mechanisms for motor vehicles
IPC: B62D7/18
Filed: 1926-06-29
Abstract: 254,719. Thouvenot, P., (Assignee of Dienne, J.). July 1, 1925, [Convention date]. Non-reactive steering-mechanism; deflectable axle-ends.-Comprises steering-gear in which the stub-axles or any part of the mechanism are normally held in any adjusted position by a braking device, and the operating member first separates the braking surfaces and then rotates the steerable member. The invention is shown applied to a stub-axle 5 having fixed thereto a sleeve 12 with a conical part 12<a> which can rotate in a corresponding part of the axle 1 and forms the steering pivot. The steering-arm 24 is rigid with a pin 14 passing through the sleeve 12 and coupled therewith by a pin 15 allowing some lost motion by means of slots 17. A collar 16 is fixed by the pin 15 to the pin 14 and another collar 13 is fixed to the sleeve 12 and therefore to' the stub-axle. Balls 28 are interposed between the rings 16, 13 and rest in recesses 27 therein, shaped as shown in Fig. 4. Normally the weight of the vehicle acting on the axle 1 causes the conical part of the sleeve 12 to jam in the axle and thereby lock or brake the stub-axle against movement due to road shocks. When the steering-arm 24 is operated the pin 14 and ring 13 are first rotated slightly in the sleeve 12 and ring 16 due to the lost motion, and this movement between the rings 16. 13 causes the balls to move in their recesses and move the rings further apart, thus raising the axle 1 and relieving the braking action between the sleeve 12 and the axle 1. The continued movement of the steering-arm then rotates the stub-axles freely to the desired position, after which the balls 28 return to the normal position and lock the stub-axles again. A thrustbearing 29 is provided between the ring 16 and a ring 19 abutting against the axle 1. The invention may be applied to steering-wheels having a castor action, i.e. a tendency to return to the straight-ahead position, the stub-axles being locked against road shocks in this position only. In a modification the invention is shown applied to the steering-shaft which controls the worm of the steering-gear, the force which normally brings the conical braking surfaces together being supplied by a spring. Instead of the balls 28 other means. such as inclines, screws or wedges may be used to separate the conical braking surfaces.

Filed: 1966-04-14
Abstract: 1,089,077. Valves. VAPOR CORPORATION. April 14, 1966 [July 16, 1965], No. 16385/66. Heading F2V. A valve assembly comprises a main valve 96 pilot valve 144, metering valve 98, and a check valve 68, and with a solenoid 134 de-energized the pilot valve 144 is unseated to place a chamber 105 in communication with atmosphere so that springs 104 urge the main valve 96 on to its seat 66. Concomitantly when there is no flow through the assembly a spring 82 forces the check valve 68 on to its seat 64. Upon energizing solenoid 134 the chamber 105 is disconnected from atmosphere and when pressure fluid is applied to an inlet 60 the check valve 68 is unseated and rests against stops 26, the fluid leaking past a piston 92 into chamber 105. When the solenoid is energized the pilot valve 144 vents the chamber 105 whereupon the fluid acting on the other side of the piston 92 moves the latter to the left and unseats the main valve 96. The chamber 105 is connected to the pilot valve 144 through metering valve 98, which is formed by the rod of piston 92, the valve 98 comprising a multi-port sliding valve which gradually reduces the passage for the venting of fluid from behind the piston as the main valve opens to prevent the last-named from opening too rapidly. The main valve is seated by closing the pilot valve 144 whereupon fluid again builds up behind the piston 92 until the pressure on both sides thereof is equal when the springs 104 cause the main valve 96 to close.

Title: Preparation of sour milk and sour cream by chemical means
IPC: A23C13/16
Filed: 1949-06-23
Abstract: Sour milk or cream particularly for use in butter making is prepared by reducing the temperature to 6 DEG C or below and adding acid to raise the acidity in the case of milk to pH 4.7-4.8 and in the case of cream to pH 4.9-5.1.  The acid which may be lactic, citric or acetic and may also incorporate formic acid, propionic acid, acetaldehyde diacetyl and amylacetate, is added as a fine spray while the milk or cream is continuously stirred.  In the preferred method for sour milk the milk is first pasteurized and cooled to 0-6 DEG and then a mixture of 75-90 per cent by weight of lactic acid and 10-25 per cent by weight of acetic acid diluted to about 40 per cent concentration is added as a thin spray while the liquid is stirred until a pH 4.7-4.8 is reached.  The milk is allowed to stand and the temperature maintained below 6 DEG C.  When required for use the temperature is raised to 18-20 DEG C which is maintained until coagulation.  In the preferred method for sour cream, the cream is pasteurized and cooled to 0-6 DEG C and a mixture of 60-90 per cent lactic acid and 10-40 per cent acetic acid diluted to 40 per cent concentration is added as above until a pH of 4.9-5.1 is reached. The temperature is quickly brought to 18-20 DEG C which is maintained until the cream coagulates when it is cooled to 0-2 DEG C which is maintained until use.

Title: An Improved Machine for Milling External Screw Threads, Spiral Wheels, Keyways or the like.
IPC: B23G1/32
Filed: 1916-11-29
Abstract: 111,179. Jackson, C. E., Oldfield, T., and Oldfield & Schofield Co. Nov. 29, 1916. Gear - cutting; milling screws; lathes. - In a machine for cutting ordinary screw-threads, left or right handed external spiral threads or wheels, long keyways and flutes or spur wheels a cutter 7 is held in a semicircular headstock and swivels and is locked in the desired angular position in an annular T- shaped slot in a head 3 on the machine saddle 4. The cutter is driven through gears 9, 10, 11, 15, 16, 18, 19, 18<A>, 19<A> from the shaft 17, Figs. 6 and 7. The desired traverse of the saddle is effected by right and left hand worms 21, 22, Figs. 4 and 8, loosely mounted on a sleeve 23 which is driven c o n - tinuously by bevel-gearing 30 connected up to the main shaft. A longitudinally movable shaft 24 with a spring ball catch 26 and a milled head 25 has a key 27 passing through a slot in sleeve 23 and which can engage worm 21 or worm 22 or assume a neutral position. Worm 21 continuously engages a wheel 31 on the fast headstock, and worm 22 engages a wheel 33 engaging a wheel 34 on the leading-screw 35. Incorrect movement of the shaft 24 is prevented by a crosspiece 45<A> having a recess 46 engaged by a collar 47 on the shaft. The piece 45<A> is connected to a lever 44 on the reversing shaft 45. For cutting ordinary threads, the key 27 engages worm 21 which is linked up with shaft 35 by a wheel on the headstock spindle engaging a train of wheels carried on the arm 37. For cutting flutes, spurwheels, or key-ways, the key 27 engages the wheel 22 and, through wheels 33, 34, the screw 35, the wheel 31 being stationary. The key 27 also engages worm 22 when cutting spirals, and the wheel 22 actuating the screw 35 drives, through suitable gears 36, 36<A>, 38, 41, a wheel 42 fast on a boss 43 of the worm 21 and thus the wheel 31. The wheel 38 is mounted upon the end of a longitudinal movable boss 39, the movement of which locks the reversing-lever in its neutral position by means of a plunger 49 and lever 50, and which is held in its end positions by means of the plunger 49 which engages the shaft 39<A>. When screw-cutting, no other operations can take place, the position of the arm 37 prevents a return io spiralling, because it prevents the movement of the sleeve 39, and the reversing-lever 43<A> is locked in its neutral position by the collar 47 entering the recess 46. When spiralling or splining, inadvertent operation of the shaft 24 is prevented by the cross-piece 45<A> which comes in the way of the collar 47 when the lever 43<A> is moved to a live position. An automatic knockoff mechanism operating a belt-shifting device to stop the machine when the carriage has reached the limits of its traverse is provided and comprises a tappet-actuated bar 54 which operates a bell-crank 59 which acts through release studs 60, 61 to move another weighted bell-crank 62 connected to a belt-shifting wire 64.
