Title: Improved means for controlling the rebound of springs of vehicles
IPC: B60K25/10
Filed: 1922-03-03
Abstract: 191,647. Pope, R. March 3, 1922. Vibration-dampers.-Means for controlling the rebound of the springs of motor vehicles comprises a worm upon the tail shaft and adapted to drive a worm-wheel upon a spindle on which is a free-wheel clutch which is engaged through flexible connections, including a snring. with the rear part of the vehicle upon a wheel shock occurring in such a manner as to lock the axle in its raised position with respect to the chassis from which it is gradually lowered as the vehicle moves forwards. A worm 8, Fig. 2, on the tail shaft 5 between bearings 7 on the shaft casing 6 gears with a worm-wheel 10 on a spindle 11 mounted in a compartment 9 of the casing 6. Towards each end of the spindle 11 is mounted a free-wheel clutch 12, Fig. 3, the outer or fixed part engaging a squared or equivalent part on the spindle, while the inner part has secured thereto a sprocket-wheel 13 engaging a chain 14, Fig. 1. One chain 14 is connected at one end to a spring 15 secured to the chassis 18. or the vehicle bodv. and at the other end to a band 16 passing frictionally over the differential casing between guide lugs 17 and secured to the chassis. This connection may be effected through a bolt 21. Fig. 4. compression spring 20, and a bracket 18 in order to absorb small shocks. The other chain 14 is similarly connected to a spring 15 secured to the gear casing 19 and to a band 16 passing round the front axle and secured to the chassis. When a stock is received by, say the rear wheels. the rear axle approaches the chassis and the spring 15 contracts, turning the sprocket-wheel 13. but immediately rebound is prevented bv the locking of the clutch and the return of the axle and chassis to their normal relative position takes place gradually as the spindle 11 is rotated during two revolutions of the wheels. The clutches are rendered inoperative during reverse movement of the vehicle by forks 24 operated by a lever 27 connected to the gear-box control lever, the clutches moving outwards against springs 23.. Specification 574/12 is referred to.

Title: Improvements in the manufacture of polyurethane foam sheets
IPC: B29C44/34
Filed: 1957-02-26
Abstract: A method of making a sheet of polyurethane foam of substantially open-cell structure from a liquid mixture which forms such a foam by gas expansion to a fluid foam and subsequent gelation to a solid foam, comprises supporting said mixture during at least a part of the expansion while the mixture is fluid and during gelation on the surface of a carrier liquid while confining the mixture to a predetermined area on the surface.  The materials for forming the foam comprise a polyetherglycol or an alkyd polyester having predominantly alcoholic end groups and an acid number less than 3.0 and a liquid organic diisocyanate together with water, foam stabilizer and a catalytic amount of a tertiary amine.  The carrier liquid must not be a solvent or a swelling agent for the foam-forming mixture or the polyurethane, and the foam must spread on the surface of the liquid (i.e. the surface tension of the carrier liquid must be greater than the sum of the surface tension of the foam-forming mixture and the interfacial tension between the carrier liquid and the foamforming mixture).  The density of the carrier may be greater or less than that of the foamforming mixture.  The liquid preferably is volatile enough to evaporate rapidly below 100 DEG  C. The preferred carrier liquid is water.  Glycerine, fluid silicones, glycol and mineral oil are also suitable.  In examples (1) and (2) a mixture of diisocyanate-polyether adduct (from 4.4 mols. of tolylene diisocyanate and one mol. of polypropylene ether glycol of m. wt. 2000), polydimethylsiloxane (foam stabilizer), diethyl cyclohexylamine and water, is stirred and run into a body of water in a tray.  The mixture which at first sinks, rises when expansion begins to cover the surface of water with foam which gels and cures on standing; (3) a similar process is applied to a mixture of an adipic acid/diethylene glycol/trimethylolethane polyester, tolylene diisocyanate, polyoxyethylated vegetable oil, N-methylmorpholine and water; (4) glycerine and (5) silicone fluid are used as carrier liquids for the reaction mixture such as is used in Example (3).

Title: Improvements in or relating to detectors of smoke and other suspensions
Inventor: HANSOM BERNARD STEPHEN
IPC: G01N21/53
Filed: 1960-02-24
Abstract: 919,640. Photo-electric smoke detection. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. May 19, 1961 [Feb. 24, 1960; April 9, 1960], Nos. 6500/60 and 12719/60. Class 40 (3). A detector for smoke and like suspensions includes a light source 12 and three photosensitive devices 14, 15 and 16. Light from source 12 passes through a slit 13a in a partition 13 in the apparatus and falls directly on device 15. The presence of smoke in the light path causes a reduction in the amount of light falling on device 15. In the absence of smoke, device 14 is not illuminated, or is illuminated to only a small extent. Smoke particles scatter light from the main beam and increase its illumination. Device 16 receives light direct from source 12 through adjustable attenuator 19, 20 and it is so arranged that under normal conditions (without smoke) the output from devices 14 and 16 exactly balances the output from device 15 with which they are connected in parallel but with opposite polarity. Smoke drifting in through louvres 11a causes an outof-balance current amplified by a transistor amplifier and used to operate a relay controlling an alarm lamp. For checking purposes a normally short-circuited lamp 17, in series with two lamps in parallel forming source 12 is provided. Removal of the short-circuit causes illumination of device 14 and operation of the relay unless one or both lamps 12 have failed. The devices 14, 15 and 16 are photo-voltaic cells and 14 may be a silicon cell and the remaining two selenium cells.
