Title: Electroslag Remelting
IPC: B22D23/10
Filed: 1980-04-09
Abstract: At least one electrode is melted down in an electroslag remelting furnace and a gas, such as argon, is concurrently blown into the liquid slag in a jet directed towards the slag- immersed portion of the electrode or electrodes to create a slag flow in the region of the electrode, thereby accelerating melting-down.

Title: Compton scatter diagnostic apparatus for determining the internal structure of a body
IPC: G01N23/04
Filed: 1981-08-21
Abstract: In Compton scatter apparatus for determining the distribution of local electron density in a body, a source 1 which provides three photon energies E1, E2, E3, directs a pencil beam 3 through the body 5. Radiation 6, 6', scattered from respective elements P along the beam, passes via a transverse slit 8, 8', and is detected by corresponding detectors 10, 10'. Each detector output is fed to three window circuits and corresponding element scatter signals for each energy S(E1). S(E2), S(E3), are fed to a computer. The improvement comprises initially carrying out similar measurements on a reference phantom resembling the body, storing the corresponding reference scatter signals V(E1), V(E2), V(E3), in a store and causing the computer to generate the quotients S(E1)/V(E1) ...etc., for each photon energy. The local electron density is then computed from these quotients using known data relating to the reference phantom. <IMAGE>

Patent GB-2093200-A (GB)
Title: Rear Cover for a Camera Housing
IPC: G03B17/02
Filed: 1982-01-27
Abstract: A cover 3 is adapted to close an opening in a camera housing 1 through which access can be gained to a film compartment, and comprises a relatively rigid section 4 having ribs 3d thereon and two relatively elastic sections 5 on either side thereof. The ribs 3d define a generally flat pressure surface which confronts a film guide surface 1b in the film compartment, and when the cover 3 is closed the elasticity of the sections 5 causes the pressure surface to be urged against the guide surface 1b. The conventional film pressure plate can thus be dispensed with, enabling the cover to be made of relatively small thickness. Where the camera is adapted to receive cassettes of film, rather than film in cartridges or on spools, the guide surface 1b is replaced by a support surface for a web portion of the cassette, and the pressure surface defined by the ribs 3d takes the place of the usual cassette applicator springs. <IMAGE>

Title: Impact pulverizers
IPC: B02C13/18
Filed: 1982-02-02
Abstract: A machine for comminuting material by impact has a hollow impeller (106) rotatable about a substantially vertical axis. The impeller (106) has an upwardly opening material inlet and at least one radially outward material outlet. A tube (102) serves to feed material to be comminuted into the material inlet. The lower portion (104) of the tube (102) rotates about its longitudinal axis and imparts an angular velocity to the material fed therethrough. Material entering the impeller (106) travels along at least a portion of the interior walls of the impeller and on emerging from the impeller strikes an anvil (117) where comminution occurs. <IMAGE>

Abstract: The invention is related to battery driven, hand held massagers. The firm connection between the motor unit (B & C) and the case (G) is replaced with modified suspension, the whole forming a low-pass mechanical filter. The required low frequency vibrations are transmitted to the case and the higher frequency components are attenuated. The ear being more sensitive to these higher frequencies, the effect is a considerable reduction in the audible noise. <IMAGE>

Patent GB-2105823-A (GB)
Title: Butterfly valve
Inventor: BEAUCHAMP DAVID COLSTON
IPC: F16K1/226
Filed: 1982-09-08
Abstract: A fire-safe butterfly valve (FIG. 2) provides bi-directional sealing. In normal duties a polymeric seal provides forward and reverse sealing against the edge of the valve disc, the polymeric seal being resiliently loaded in the axial direction of the valve by a resilient metal ring. The metal ring provides a bi-directional seal with the disc edge in the event of destruction of the polymeric seal by fire. The metal ring in transverse cross-section consists of an arm having a curved radially inner end presenting a convex surface for engagement with the disc edge. For fluid pressure acting from the smaller diameter side of the disc, in the burnt out condition, the curvature of the radially inner end of the metal ring gives rise to an increased sealing force with the disc edge as the disc moves in response to the fluid pressure and the ring inner end remains in rolling contact with the disc edge.

Title: Pressure cooker relief valve assembly
Inventor: ROBINSON GEOFFREY
IPC: F16K17/12
Filed: 1982-10-22
Abstract: A relief valve assembly for pressure cookers in which the valve port (6) is controlled by a predetermined weight. A skirt portion (19) forming part of the mass of the weight surrounds the valve port so forming a chamber. The skirt portion has an opening (18) in it such that gas entering the chamber from the pressure cooker via the valve port can escape to the atmosphere in a single predetermined direction, e.g. away from a hand grip portion (17). A modification, in which a cam surface is used to relieve the pressure of the weight by rotation of the hand grip, is also disclosed (Figs. 7-10, not shown). <IMAGE>

Title: Washing chemical from textile fabric
Inventor: BACHAND JEFFREY PAUL
IPC: D06B5/08
Filed: 1983-02-07
Abstract: A travelling textile fabric (22) (e.g. cotton) is impregnated with a chemical solution (34) (e.g. caustic soda) to treat the fabric, and the chemical is then recovered from the fabric for re-use. This is done by a plurality of washing stations (62, 64, 66, 68, 70) at each of which a small amount of fresh water is sprayed onto the fabric. Each washing station has a vacuum box (48, 50, 52, 54, 56) arranged to apply a high vacuum to the fabric through a slot to extract the washing water together with some of the chemical from the fabric. The liquid collected by each vacuum box is delivered to an evaporator (74) to concentrate the solution so that it can be returned to the impregnation station (32). A vacuum box (46) may be arranged to extract solution from the fabric before it reaches the washing stations, this extracted solution being undiluted and returned directly to the impregnation station (32). By using fresh water at each vacuum washing station the extraction of the chemical is more efficient and less water is needed compared to known methods in which water from one suction box is cascaded onto the fabric at the next washing station. <IMAGE>

Title: Motor vehicle passenger compartment air heaters
Inventor: MATSUDA TAMOTSU
IPC: B60H1/00
Filed: 1983-02-22
Abstract: An air heater comprises a casing (1) for mounting in the front of a motor vehicle body. In the casing are an air intake chamber (3) and a mixing chamber (4) downstream of the air intake with a heater core (H) disposed between these two chambers. The core has hot air passages (101-104) with radiation fins (121-124), and blast passages (111-113). The hot air passages and blast passages are arranged in laminar formation and have a progressively increasing heating effect from the top (in use) of the core to the bottom on air flowing through the core. This is achieved by varying the pitch gaps of the radiation fins in adjacent hot air passages or by varying the vertical gaps between adjacent pairs of hot air passages. Regulation means (6) varies the opening areas of the hot air passages and the blast passages. This heater has excellent temperature controllability, is easy to operate, compact in size and light in weight. <IMAGE>
