Title: Improvements in or relating to mechanism preventing reverse movement
IPC: B60T7/12
Filed: 1932-07-25
Abstract: 392,022. Preventing reverse movement of motor vehicles. TENNANT, W. J., 111, Hatton Garden, London.- (Matson Co. ; 40, Main Street, Concord, New Hampshire, U.S.A.) July 25, 1932, No. 20972. [Class 103 (i).] A device for preventing reverse movement of motor vehicles comprises a member adapted to turn on a pivot to throw the device out of action and partially surrounding a circular flange 28 fixed to the transmission shaft and engaged by a wedging member 36 in a chamber in the member to prevent rotation in one direction only. When the transmission shaft tends to move in a reverse direction the members 36 are wedged between the surface 28 and freely rotatable rolls 35 contained in cylindrical chambers in the members 32, 39. The free ends of the members 32, 39 are drawn together by a spring 41 and a latch 44 on a lever 43 pivoted to the members 32 engages a latch 45 on the member 39 and is locked in this position by a member 48 on a latch 47 pivoted on a shaft 46. On the sliding bar projecting from the vehicle gearbox and adapted to engage reverse gear is mounted an upwardly and forwardly extending member 51 having a laterally extending part adapted to move the latch 47 and member 48 to allow the wedging members to be unlocked when reverse gear is engaged. Movement of this sliding bar also by means of an incline raises lever 43 and the latch 44 out of engagement. Reverse movement of the transmission shaft now spreads the members 32, 39 apart against the tension of the spring 41 until a locking lever 49 pivoted on the lever 43 engages the upper inner face of the member 39 and holds the member 32, 39 apart. The gear-box sliding bars are also provided with inclines adapted to disengage the locking lever 49 and bring the wedging members into locking position, when any forward speed is engaged. A modified form of wedging member is mounted for rocking on a spring-pressed rocking bed in substantially rectangular chambers in the members 32, 39. The engaging faces of the wedging members are wedge-shaped in crosssection and engage a wedge groove in the member 28. In a further modification the wedging members are formed by spring-pressed rollers in wedge-shaped chambers in the members 32, 39.

Abstract: 919,770. Conveying bottles. HILL ENGINEERING CO. (HULL) Ltd., THOMAS. May 29, 1961 [June 15, 1960], No. 20985/60. Class 78 (1). A random supply of bottles is fed at 12 by means of guides 14 and 15 on to endless conveyers 16 whence they are removed by driven transverse belt 18 which moves them leftwards and at the same time agitates them by rotating them in order to avoid a jam. Bottles are thus delivered on to conveyers 20 and 22 which convey them until they meet driven transfer belt 26 which delivers them all on to the belt 22 for discharge at 24. Any bottles which pass beyond the side of conveyer 22 are collected by conveyer 28 and conveyed back to be discharged by curved guide 30 back on to belt 22. In. this way a uniform delivery of bottles is achieved on belt 22. The angle of transfer belts 18 and 26 may be varied.

Title: Process for continuously treating metal-containing and acetal-containing aldehydes and dialdehydes
IPC: C07C27/22
Filed: 1957-07-04
Abstract: Aldehydes obtained by the oxo process and containing acetals and metals as impurities are purified by treating with water in the liquid phase at a temperature of 150-200 DEG C. in a vessel free from packing and other contacting or distributing means, into which vessel the crude aldehyde is introduced at or near its lower end, purified aldehyde and gaseous products being withdrawn from the upper part of the vessel and water containing metals and/or metal compounds from the lower end.  The vessel may conveniently be a vertical tube and the process may be carried out batchwise or continuously.  The water may be precharged to the vessel and the aldehyde passed through it or the water may be introduced as a mixture with the aldehyde.  The process is particularly useful for the purification of crude dialdehydes obtained by the oxo synthesis.  In the examples (a) tricyclodecane-dialdehyde obtained from dicyclopentadiene by the oxo synthesis; and (b) a C10 aldehyde obtained from propylene trimer by the oxo synthesis, were purified according to the above process.

Abstract: 1,183,952. Colour television; automatic phase control systems. R.C.A. CORPORATION. 8 May, 1967 [23 May, 1966], No. 21353/67. Headings H3A and H4F. In a colour television receiver adapted to receive an NTSC type subcarrier, the hue of the colour picture is adjusted by means of a phase-shifting circuit (part of phase-shift circuits 24, Fig. 1) coupled between the output of a colour reference oscillator 21 and an automatic frequency and phase control detector 22 which utilizes the separated burst component from burst separator 20 to synchronize the generation of the colour reference oscillation in oscillator 21 with respect to the burst component. Detector 22 which includes a balanced phase detector produces a correction voltage representative of the phase and frequency difference between the separated burst component and the phase shifted colour reference oscillation coupled across the phase-shifting circuit. The phaseshifting circuit comprises the series combination of an inductor and a capacitor and a variable resistance coupled across the capacitor, Fig. 2 (not shown), and the phase is shifted by changing the resistance of the variable resistor, the circuit being such that its impedance remains constant throughout the range of the variable resistor. Preferably, the inductive reactance of the inductance equals one-half the capacitive reactance of the capacitance at the frequency of the colour reference oscillations and a fixed capacitor having relatively high impedance is coupled between the colour reference oscilator and the phase shifting circuit. The variable resistance may be mounted on the front panel of the receiver and be coupled to the capacitor by means of a shielded cable, the capacitance of the cable being added in parallel to that of the capacitor and the value of the capacitor being selected to meet the above impedance requirements.

Filed: 1968-05-06
Abstract: 1,208,666. Egg compositions. STANDARD BRANDS Inc. 6 May, 1968, No. 21429/68. Headings A2D and A2E. An egg composition comprises a mixture of egg yolk and egg white and a small amount of a water soluble edible phosporous compound, said composition containing such an amount of phosphorus compound and being at such a pH that the phosphorus compound is effective to impart a fresh egg-like flavour to said composition but insufficient to substantially affect the normal coagulation characteristics and the bacterial decomposition of the composition. The phosphorus compound may be an edible ortho-, pyro-, trilinear, polylinear or polycyclic phosphoric acid or salt thereof and is preferably present in an amount of about 0.5%. For liquid eggs the pH is adjusted, e.g. by the addition of orthophosphoric acid, to lie between 5.5 and 7.0. For scrambled eggs the maximum pH may be slightly higher, depending on the particular phosphorus compound used, e.g. up to 8.5 when pyrophosphates are used. The addition of the phosphorus compound both preserves the colour of fresh eggs and restores the fresh egg-like colour of eggs that have already turned a muddy brown colour,

Abstract: 981,590. Vehicle wheel Suspensions. METALASTIK Ltd. May 19, 1961 [June 17, I960], No. 21476/60. Headings B7D and B7L. A vehicle axle box housing 60 (for a non- self aligning axle box) is secured, through a hemi-spherical joint 62 having a rubber interlayer 63, to one end of a radius arm 61 secured at its other end, through a hemi-spherical joint 65 having a rubber interlayer 64, to the bogie frame 10, whereby the axle box and the arm may rise and fall and swing transversely of the frame, a pair of rubber springs 66, in V-formation, being interposed between the axle box housing and the frame 10 and which springs are subjected to combined shear and compression during the rising, falling or transverse swinging of the arm 61. The latter is maintained under tension by the springs 66, which abut a port 28, carried from a guide 29 on the frame 10, a bolt 30 passing through port 28 and screwed into the frame facilitating vertical adjustment of the axle box housing in relation to the frame. A stop (not shown) is provided on the frame immediately behind the end 68 of the arm 61, so that if the arm gets into compression it cannot move far in relation to the axle box housing. If the axle box is self-aligning then the outer end radius arm is made rigid with the housing and the inner end is pivoted by a horizontal rubber bush, to the frame. In another embodiment, for a non-self-aligning axle box the axle box housing is rigidly clamped to the outer end of a radius arm, in the form of a plate, whose inner end is connected through a horizontal pivot to a pin secured by trunnion blocks to the frame 10. The pivot comprises inner and outer pre-stressed and concentric rubber bushes, the outer bush being cored-out on its side nearest the axle box so as to give low resistance to transverse bodily movement of the plate and to rising and falling movements thereof. The latter movement in are accommodated mainly by torsional shears the inner bush. In this embodiment the rubber springs with interleaves are cylindrical. Safety means for supporting the axle box in event of failure of the rubber springs are described with reference to Figs. 3 to 5 (not shown). According to the Provisional Specification, chevron-shaped springs may replace separate springs in V-formation. Also the interleaves of the springs may be curved or twisted. Moreover the radius arm may be replaced by a pair of vertically spaced parallel links pivoted through rubber bushes to the frame 10 and the axle box housing.

Filed: 1923-08-30
Abstract: 212,871. Chile Exploration Co., (Assignees of Burdick, C. L.). March 16, 1923, [Convention date]. Alloys.-An electrode resistant to anodic disintegration is made of an alloy containing copper, silicon and iron in proportions which may be expressed as a mixture of copper silicide Cu3 Si and iron silicide Fe Si and also containing lead with or without free silicon. The lead content may be from 1 to 5 per cent. Tin may also be added in proportions up to 4 per cent. The composition may lie between the limits, 19 to 40 per cent of silicon, 6 to. 20 per cent of iron, 1 to 5 per cent of lead, not more than 4 per cent of tin, and the remainder substantially copper. The preferred composition is 23-27 per cent of silicon, 7 to 9 per cent of iron, 1.9 to 2.5 per cent of lead, 1 to 2 per cent of tin, and 60 to 65 per cent of copper. The alloy may be made by melting together 330 kilograms of copper and 170 kilograms of ferro-silicon containing 75 per cent silicon and after skimming off any slag adding 35 kilograms of a lead-tin sulphide. The latter constituent may be made by melting separately 2.5 parts of scrap lead and one part of pig tin and then mixing them together with the required amount of sulphur. Manganese should be excluded as far as possible since it militates against the incorporation of lead.
