Title: Improvements in acoustic alarm devices
IPC: G08B15/00
Filed: 1949-04-14
Abstract: 653,724. Retractive switches. KISCH, A. H. April 14, 1949, No. 10232. [Class 38(v)] [Also in Group XXXVIII] In an acoustic alarm device for bags or like hand-portable articles a hand-grip normally keeps apart two electric contacts but when released it allows the contacts to close, and is automatically latched in the released position. When a bag A is being carried, a grip h is raised to the underside of the handle against the pressure of a helical spring f. A hollow cylinder g on the stem b of the grip h is'made of insulating material and prevents two contact springs i, l from touching each other. When the grip h is released e.g. as the result of an attack on 'the carrier, the spring f forces down the cylinder g and allows the contacts i, l to close the circuit to an electric horn o. Since the cylinder g is, in this position, latched beneath the contact spring l the horn continues to sound and can be silenced only by first opening the bag A and then an aluminium or plastic case a containing the switch contacts, and manually lifting the contact spring l to allow the grip h to be raised. The grip may be latched in the raised position by turning a shaft s so that a cam r thereon comes beneath the cylinder g and prevents its descent.
Patent GB-941461-A (GB)
Title: Battery separators
IPC: H01M50/443
Filed: 1961-03-21
Abstract: A battery separator comprises a porous sheet of random fibres a major proportion, e.g. 90%, of which consist of cellulosic fibres coated with a polymer such as polythene, polypropylene, polybutadiene, isoprene, or other 1-olefin of less than 6C. atoms, or tubular fibres of such a polymer, the remaining fibres being longer cellulosic fibres, e.g. kraft fibres, the polymeric fibres being interconnected by fusion at their crossing points. Fusion may be effected by the use of a solvent or by hot-pressing e.g. between hot calender rolls, which may also be profiled to produce a corrugated sheet.  Such a sheet may be coated with polymer on the ridges to reduce the permeability to electrolytes of these parts relative to that of the compressed portions.  The separator may be impregnated with a wetting agent, and the fibres constituting it may be deposited on the battery plates themselves. Coating of the cellulosic fibres may be effected by polymerizing 1-olefin monomers on their surfaces, for example by suspending the fibres in an organic or other liquid which is a non-solvent for the fibres and the monomer, e.g. toluene, and, after drying the mixture by refluxing under nitrogen, adding one component of a catalyst composition followed by the other component and the monomer, the reaction being continued at the required polymerization temperature until sufficient polymer has been deposited whereafter the coated fibres are filtered off, made into a slurry with water, and formed into a mat, for example on a paper-making machine after the addition to the slurry of longer cellulosic fibres.  Catalyst components mentioned are (i) metallic alkyl or aryl compounds, e.g. aluminium triethyl, and (ii) halides or esters of titanium, zirconium, vanadium or chromium, e.g. titanium tetrachloride.  In an example these are used to polymerize ethylene, supplied in displacement of the nitrogen used in the refluxing step and gradually increased in pressure.  A wetting agent, such as sodium dioctyl sulpho-succinate, may be added to the slurry sufficient to give 0.15-0.25% of the final product.  The mat formed is dried and the fibres sintered together by passing through a heated chamber on a wire belt; the sintered mat may then be calendered between heated rolls having rib-forming grooves.  The fibres may be formed into polymer tubes by dissolving out their cellulosic core, while they are in dry condition, with strong sulphuric acid or caustic soda solutions, carbon disulphide, cuprammonium, or other cellulose solvent.

Abstract: 450,572. Tipping-vehicles. EDMONDS, P. J., The White House, Itchen Abbas, near Winchester, Hampshire. April 3, 1935, No. 10369. [Class 108 (i)] A tipping-wagon is arranged to tip in two stages, the initial stage bringing a member in contact with the ground and the final stage being brought about by subsequent travel of the wagon over the ground. The body is mounted to tip about an axis 14 and comprises front and rear walls 18, 19, the front wall 18 being curved. Two side members 16 are provided of the shape shown and may be provided with spikes 18<a>. The body is held in travelling position by pivoted latches 20 engaging brackets 24 such that when the latches are released by means of the cord 20<a> the body tips by gravity until the curved portions of the side members 16 engage the ground whereupon, on forward movement of the wagon, the body completes its tipping into the position shown in Fig. 3, and may be retained in this position by the latches 20 engaging stop brackets 26. The edge 30 of the wall 18 or an edge, adjustable or not, on the chassis serves as a rake or leveller for the dumped material. The tipping may be arranged rearwardly by placing the vertical wall 18 to the front so that the centre of gravity of the body is to the rear of the tipping axis 14. In the case of tipping about a longitudinal axis provision may be made by means of chain or friction drive whereby after initial tipping the motion of the wheels may complete the tipping.

Title: Tensioning devices for electric transformer windings mounted on eleastic members
IPC: G01D5/20
Filed: 1971-04-21
Abstract: 1352707 Transformers INDUCTOSYN CORP 21 April 1971 [22 April 1970] 10406/71 Heading HIT [Also in Division G1] A position-measuring transformer 6 comprising two relatively movable transformer members 5 and 9, has one of the members 9 in the form of an elastic tape carrying a winding 10, one end of the tape being connected directly to a fixture 34 whilst the other end is connected via a tensioning device 18 to a second fixture 27. One such tensioning device 18 (Fig. 3) comprises a spring 24, a member 16 connected to the tape and the spring, the member 16 having a shoulder 12 which acts as a reference point, an adjustment member 32 on which a lockable nut 20 is threaded the position of the nut relative to the shoulder 12 indicating when the tape is stretched to a required extent, and a sleeve 22 which abuts the shoulder 12 on the member 16. To set the tape to a given calibrated tension and hence a given length, the nut 41 is tightened until the required tape length is achieved. In order to exert a fine control on the increase in tape length, the increase in length of the spring under tension is made about 50 times that of the tape for the same applied tension. The nut 20 is then rotated to a known small distance Dn from the sleeve 22 and is locked in position. If the tape has to be removed from the fixtures and is required to be set up between two other fixtures where the fixture separation may be slightly different due to manufacturing tolerances, the tape can be set to its calibrated tension and hence length merely by adjusting the nut 41 until the locked nut 20 is again a distance Dn from the sleeve. Further tensioning devices are described based on the same principles in which the spring of the tensioning device is compressed rather than stretched (Fig. 5-7, not shown) U.S.A. Specification 3,522,568 is referred to.
