Title: Fire resistant insulating panels for low temp. use - comprising metal shell lind with alkali metal silicate and ffffilled with polyurethane foam core
Inventor: COOK SANFORD LEE
IPC: E04C2/38
Filed: 1976-11-30
Abstract: Insulating panels comprise a metal plate shell with upper, lower, side and end walls, a layer of an alkali metal silicate which covers virtually the whole interior surface of the shell, and a cast core of polymer foam resin which fills the interior of the shell. Pref. the intumescent layer in the panel is of sodium silicate and the foam core is of polyurethane. In a pref. method of construction, the upper edge of the panel is provided with a series of ventilation holes and the alkali metal silicate is applied to the shell surface in the form of preformed sheets which are opt. reinforced with fire resistant fibres. The upper silicate layer is provided with holes which correspond with the ventilation holes in the top edge of the shell.

Title: Automatic camera for daylight or flash - has automatic aperture disengaged by flash insertion and exposure controlled by shutter setting and focused distance
Inventor: ETTISCHER HELMUT
IPC: G03B7/16
Filed: 1977-03-22
Abstract: Photographic camera has shutter speed and aperture adjustment effected automatically by electromagnets. There is an automatic focussing device and a facility for single or multiple flash unit. Flash exposure determination is made automatic by coupling aperture and focusing control mechanisms, but primarily by incorporating a photocell in the mechanical linkage controlling shutter and aperture. A release lever is depressed which drops a linkage to expose a photocell behind an aperture in part of the camera aperture linkage. The photocell measures during exposure and its associated circuitry determines when the electromagnets initiate shutter closure. For flash exposure a lever is depressed and aperture linkage disengaged so that the largest aperture is selected. Control is then by measuring light for shutter control.

Title: Corrugated plastics foil mfg. appts. - having slit orifice above corrugated conveyor on which foil is cast and cooled for required period
Inventor: SAATHOFF WERNER
IPC: B29C48/12
Filed: 1977-04-15
Abstract: Appts. for mfg. plastics corrugated foil, in which the corrugations extend transversely of the longitudinal axis of the foil at an angle which is different from 90 degrees, is provided with an extruder head having a slit orifice below which moves an endless belt having the corrugated configuration. The parameters of the appts., such as the temp. of the extruder head, mass flow of the plastics melt, distance of the orifice outlet lip from the surface of the conveyor moving in a horizontal plane and the length of the conveyor, are such that the plastics melt reaches the conveyor in a liquid state suitable for casting of the foil and remains in contact with the conveyor for a period required by the foil cooling. Foil is cut into sheets which are superposed and bonded at intersections of the crests and valleys of adjacent sheets to form stacks used for dripping of liquids in cooling plants or sludge clarifiers. Prodn. of stacks immediately after casting and cooling simplifies production and sheets which are not cut from e.g. rolls are free from distortions due to residual stresses induced in the foil.

Title: Torque screw test device - converts torque to linear stress and measures strain induced in elastic rod using dial gauge
IPC: G01L25/00
Filed: 1977-04-20
Abstract: A torque measuring device has a base plate on which is mounted a pillow block with two positioning flanges between which a lever (13) is held.

An operating bar (16) is attached by a coupling to the other end of the lever and by a socket (19) and further coupling (18) to the base plate. A dial gauge (22) is coupled by a first holder member (23) to the upper end of the operating bar and by means of a second holder member (27) to the other end. The dial gauge indicates strain of the bar (16) under stress and hence provides an indirect measurement of applied torque.

Title: Fur or textile ironing machine - with inclined grooves and strips with peripheral and axial overlap in ironing roll
IPC: C14B1/54
Filed: 1977-05-04
Abstract: An ironing machine for furs and textiles has in the axial direction of the ironing roll several gps. of grooves which are alternately inclined to the right and to the left from the axis of rotation. The grooves, with a slightly raised strip along the deep end, are offset relative to each other in the peripheral direction, and overlap each other axially. The result is that, in spite of a great length of the ironing roll and its small diameter, the strips in it have an optimum angle against the roll axis. The better ironing effect produces furs with a smoother and more silky appearance.

Title: Vehicle transmission with electronic control - has transducers producing speed and throttle position signals and regulator which processes signals from manual selector switch
Inventor: BEALE JULIAN ROBERT ANTHONY
IPC: B60W30/18

Title: Capillary viscosimeter for testing plastics - has main ram piston, second rotating ram providing shear, storage, shear and compression chambers
IPC: B29C45/76
Filed: 1977-08-04
Abstract: The viscosimeter consists of a filling hopper (2) which feeds a compression chamber (3) in the upper end of a heated extruder block. The chamber leads to two further chambers of decreasing diameter (4, 5), the latter tapering off to a capillary tube set in a block (22). Plastics material is compressed in the upper two chambers and held under pressure by a ram (8). A second ram of smaller diameter passes through the centre of the first and extends to the mouth of the third chamber so that a narrow gap is established. The smaller ram is then rotated by means of a motor drive (9, 10). The material undergoes shearing and its temperature is raised so that it is plasticised and under the pressure of the larger piston is forced into the collecting chamber (5).

Title: X=ray tube anode with focal point on tungsten part - uses zirconium layer to solder tungsten part to graphite member
Inventor: FRIEDEL RUDOLF DIPL PHYS
IPC: H01J35/10
Filed: 1977-12-14
Abstract: The X-ray tube anode is intended to provide a secure soldering layer between a tungsten and a graphite part, offering a long service life. In the anode the focal point is provided on a metal part consisting, at least mostly of tungsten. The zirconium soldering layer between the tungsten and graphite parts is 20-50 microns thick.
