Title: Fusing element for anchoring fire protection transmission cables - two sleeve elements joined with fusible alloy
IPC: A62C2/24
Filed: 1974-12-13
Abstract: A fusible mechanical element is employed in fire protection installations and readily permits the anchoring of looped transmission cables connected to such items as fire doors. This method of anchoring eliminates problems of locking cables with screws to the fusing element. A fusible element (10) has two identical parts (11, 12) each being a sleeve (13, 14) and each with a collar (15, 16) at one end. A hole (17, 21) bored longitudinally through each part is threaded to provide good anchorage for Lipowitz alloy (20) which is flowed into it to join the two parts together at the ends (18, 19) opposite the collars. Cables are looped round each half of the fuse and are retained by the collars. They are released when the alloy melts.

Title: Combined radio transmitter-receiver - has contactless switch connecting dual purpose antenna
IPC: H04B1/48
Filed: 1974-12-16
Abstract: The antenna switch consists of a controllable impedance network between the antenna and the sender and receiver, which passes the signal frequency band, and of two electronic switches. The latter, when operated, make the above network non-conducting for the signal frequency band. The network consists of a T-section low pass filter, with an additional capacitor added to the shunt arm. The electronic switch is a PIN diode, and the capacitor a discrete capacitor. The resistances of the electronic switches in both passing and blocking conditions have a negligible influence. The apparent impedance network does not need to be tuned to a specific working frequency.

Title: Extruded electrode transfer mechanism - has trough tilting about electrode axis on rollers on cylindrical running surface
IPC: F27D11/10
Filed: 1975-02-28
Abstract: The mechanism is for use with a continuously-operating extrusion press from which cylindrical electrodes for electric furnaces emerge, having a tilting reception trough with a roll-off surface protruding to one side, over which the electrode rolls on tipping after parting off. The trough is so arranged that on tilting the electrode the latter is only turned about the extrusion axis, and tils about this axis, resting on a support near each end. These supports have cylindrical running surfaces coaxial to the extrusion axis on which they bear by means of rollers. A ram actuating a shaft coupled to them both and running parallel to the extrusion axis, effects the tilting movement.

Title: Roofing tile of irregular surface - has lowermost side irregular and others straight with right angles between
IPC: E04D1/04
Filed: 1975-08-25
Abstract: The roofing tile is of irregular surface, imitating a stone roof with irregular components. Three of the tile sides are straight, enclosing two right angles, while the fourth and lowermost one (5) is irregular, so as to give the impression of an irregular surface. The fourth side can be formed by several lines, one interrupted one not being in the same plane as the others. The stepped portions and the end can be of the same height. The design avoids the need for extra strong refters to support the roof, and only a few different patterns are needed to give the desired irregular effect.

Title: Sulphur granules solidified from molten sulphur droplets - delivered from vortex-chambered nozzle into water
Inventor: MALCOLM DAVID G
IPC: B22F9/08
Filed: 1975-10-03
Abstract: A process for making granules of sulphur (or similar materials) is claimed in which molten sulphur at 260-330 degrees F pref. about 305 degrees F is sprayed through a vortex-chambered nozzle with a pressure drop of less than 40 psi. pref. between 1 and 5 psi to produce a divergent, hollow, conical spray curtain which is directed downwards into the surface of water at about 100 degrees F, so that the surface is broken up into turbulent eddies which promote the formation of granules from the droplets of molten sulphur. The spacing of the nozzle above the water surface can be small enough to ensure that the spray curtain does not break up into droplets before meeting the water or sufficient to ensure that it does, a pref. spacing being of the order of 10 inches. The molten sulphur supplied to the nozzle can contain additives such as bentonite, methallic oxides and insol. fertilisers. The process is used for the mfr. of granular sulphur, partic. for use as a fertiliser with or without additives.

Title: Nonpolluting carbonising oven charging appts. - including mechanism for removing and replacing plug of charging inlet, prevents escape of smoke, dust, gas etc.
IPC: C10B31/04
Filed: 1975-10-29
Abstract: An arrangement for charging carbonising, esp. coke ovens, which ensuring there is no escape of smoke, dust, gas, etc. to cause pollution of the environment, includes a mechanism for removing and replacing the plug of the charging inlet together with a mobile channel connecting the loading hopper to the charging inlet. The installation comprises a charging cowl attached to the charging hopper, which is moved into position above the charging inlet, so as to prevent any contact between the charging inlet and the open air; the outlet through the loading hopper being blocked by the coal. The mechanism for lifting and replacing the charging inlet plug as well as the mobile trunk are arranged inside the charging cowl; the trunk moving inside the cowl from a position in which there is access for the mechanism to lift the charging inlet plug clear, to a second position where it connects the loading hopper to the charging inlet. All the operations necessary to charging from and including the lifting of the oven plug until it is replaced on its seat, are carried out inside a closed housing positioned over the charging inlet. Any escape of gas developing during loading and any access of air into the oven are thus prevented.

Title: Continuous nonwoven garment prodn. - used partic. for disposable surgical boots and caps
IPC: B29C65/74
Filed: 1976-03-05
Abstract: Continuous prodn. of garments from a nonwoven base, e.g. disposable surgical boots or caps, is achieved by passing a continuous nonwoven band through a treatment zone provide with rotating cylinders. On one of the faces of the band is placed an exterior protective or reinforcing layer, and on the other face a layer of acrylic glue, patterned to follow the desired contour of the article to be made. A second hand of nonwoven material is stuck to the first by a press. roller, and on this second band a layer of a corrosive material is deposited, patterned to follow the exterior contour of the imprinted glue. This effects a cutting out of the article after passage through a zone to activate the corrosive material. Then a second exterior protective or reinforcing layer is placed on the free face of the second nonwoven band, or the layer of corrosive material. The exterior protective layer is pref. vinylic, or a neoprene base elastomer, and the corrosive material, is pref. hydrochloric acid. The nonwoven base is pref. an acetate or viscose fibre blend. The articles can be worn by hospital personnel, e.g. surgeons. The articles made by the continuous process, are partic. light, well adapted to the form of the wearer, easy to put on, and do not soil so easily. At the same time, their cost is low enough to allow them to be destroyed after use.
