Abstract: 784.268. Turning-gear. BENDIX AVIATION CORPORATION. Oct. 4, 1955 [Oct. 4, 1954], No. 28258/55. Class 7(5) In an engine starter gearing including a motor shaft 1, a sleeve 4 splined thereon, a transmission member 14 slidably journalled on the shaft 1 and having an overload slip coupling with the sleeve, a pinion 9 slidably journalled on the shaft providing an overruning clutch connection with the transmission member, a barrel 19, rotatably connected to the sleeve and pinion, encloses the coupling and clutch connections. The motor shaft 1, with helical splines 2 and a smooth portion 3 has the sleeve 4, with internal helical ribs, slidable thereon, the sleeve being connected to a manually or electromagnetically operable shifting fork 10 loaded by a spring 8. The pinion 9 which is slidable on the portion 3, its meshing position being defined by a collar 12, is actuated from the sleeve 4 by a transmission comprising an annulus 14 slidable on the portion 3 and having overload clutch teeth 15 engaging corresponding teeth 16 on the sleeve 4, and overrunning clutch teeth 17 co-operating with similar teeth 18 on the pinion hub; the barrel 19 is connected with the pinion, by a ring 21 registering in annular grooves in both members, and the sleeve, by means of a flange 22 thereon, a series of spring washers 23 being located between one end of the barrel and the flange 22 and maintained under initial compression to allow space for disengagement of the over-running clutch 17, 18; the latter is held in the operative posoition by a spring 27. During the axial meshing movement of the pinion, the assembly rotates backwards due to the splined connection of the sleeve and motor shaft. In the event of tooth abutment the movement of the fork 10 continues, thereby compressing the spring, until at the end of the stroke the starting switch, not shown, is closed to energize the motor which causes indexing of the pinion and engine gear 11 which action is assisted by the splined connection. Overrunning of the shaft 1 is facilitated both by disengagement of the clutch 15, 16 and the ring 21 between the barrel and pinion Specification 165,242 is referred to.

Title: Improvements relating to the preparation of alkyl sulphates
IPC: C07C305/04
Filed: 1936-10-17
Abstract: Monohydric aliphatic secondary or tertiary alcohols having a chain of 8-25 carbon atoms are converted into sulphates by treating with concentrated chlorsulphonic acid at a temperature below 0 DEG  C. The alcohols may be those prepared by limited oxidation of paraffin or naphthenic hydrocarbons, e.g. paraffin wax, or petrolatum, and the neutralization of the sulphates may be effected while cooling.  In an example, the unsaponified fraction obtained from an oxidized petrolatum is extracted with methyl alcohol, and the resulting ketones and aldehydes in the extract, hydrogenated.  The mixture of alcohols so produced is dissolved in petroleum naphtha and treated with chlorsulphonic acid at 0 DEG  C. After neutralization, the unsulphonated material is removed by means of petroleum naphtha, the residue mixed with trisodiumphosphate to prevent decomposition and evaporated to dryness.  The sulphonation may be effected in the presence of halogenated hydrocarbons.  Specification 435,385 is referred to.

Title: Improvements in or relating to Vacuum Brake Boosters
IPC: B60T13/565
Filed: 1967-06-20
Abstract: 1,183,943. Vacuum brake booster systems. ALFRED TEVES G.m.b.H. 20 June, 1967 [30 Sept., 1966], No. 28431/67. Heading F2F. To enable a vehicle driver to sense the braking force exerted in a booster assisted hydraulic brake system, a reaction piston 16 is provided which is slidable in a bore of an extension sleeve member 2a of a booster piston 2. The piston end 16a is subjected to pressure in the brake primary circuit while its other end abuts pedal link rod 5, and thereby pressure is transmitted to the pedal. Likewise a control piston 17 transmits reaction force due to the secondary circuit pressure. The booster piston assembly 2, 2a, a sleeve 10 and a spacer member 20 form the primary piston, slidable in master cylinder chamber 14; while 11 is a secondary piston. If the primary circuit fails the booster piston assembly is moved by atmospheric pressure until spacer 20 abuts a disc 19 on a push rod 18 and the rod 5 and reaction piston 16 are shifted until piston 16 abuts the rod 18. Brakes are thus operated and reaction force is transmitted to the pedal being derived from pressure in the secondary circuit chamber 15 which acts, via bore 21 of piston 11, on the control piston 17 and is transmitted by push rod 18 to piston 16 and via rod 5 to the pedal. The booster piston chamber 3 is always maintained at negative pressure while chamber 4 is alternately at negative pressure and atmospheric pressure, as determined by valves operated by movement of link rod 5.
