Title: Supplementary light imaging camera - has transparent reflector mounted in housing in front of lens
Inventor: TURPIN GERALD LESLIE
IPC: G03B11/00
Filed: 1975-04-17
Abstract: The camera has a device for directing additional coloured light into the imaging lens and includes a light source, a concavely curved coloured reflector, a coloured filter, a magnifying lens and a concavely curved reflector.

Title: Single screw positive displacement rotary compressor - as sealing gears inclined to each other for two stage compression
Filed: 1975-05-03
Abstract: The compressor has a casing (2a) inside which is a single helical screw rotor (1a). The volume formed between the teeth of the rotor and the casing are sealed by two gear pinions (3a, 4a) which are carried on shafts (7a, 8a) in the casing and mesh with the rotor screw. The chambers so sealed reduce in volume as the screw turns and so compress the fluid drawn in at one end. The two gear pinions lie in planes (14, 15) which are inclined to each other so that one set of working spaces (12a) is larger than the other set (13a). The fist set (12a) form the first stage of compression and fluid is drawn off from this through an intercooler (17) before entering the second set.

Title: Low friction seal for bar in bore - has seal ring wedged between bar and elastomeric clamp ring with wedge clearance
Inventor: HITZIGER HUBERT DIPL ING
IPC: F16J15/32
Filed: 1975-06-06
Abstract: The seal is for a round bar sliding in a bore of larger diameter. A sealing ring of material with low friction coefficient is jammed between the bar and a clamping ring (5) set in a groove (3) in the bore. The clamping ring is elastomeric, and prevents fluid entering the space around the sealing ring (6). The depth of the recess (4) for the sealing ring is slightly greater than the thickness (6) of the ring, and the inner ring diameter is slightly larger than the outer diameter of the bar, so that under clamping ring pressure, there is a wedge-shaped clearance (9). The slope of this wedge must not exceed 0.02 at the widest end so that deformation of the unrestrained end is not prevented.

Title: Control for forging hammer - has stylus sensor to end forging process after fixed impact energy expenditure
Inventor: SCHROEDER HORST
IPC: B21J7/46
Filed: 1975-08-23
Abstract: The system controls the driver of a forging hammer. The foring process is terminated after a certain number of impacts. The remaining energy of the tool is measured after each impact and the measured value is converted into a signal which is stored. The measurement is obtained by measuring the deceleration of the driver or the anvil. The measured value is compared with the stored value of the previous impact. The cycle is broken and the foring is ended when the signals of consecutive strokes have values which are equal or which lie within a predetermined tolerance range. When the output values are nominally equal, a signal can be generated which produces an optical or acoustic warning or a signal which is fed into a machine control unit.

Title: Ice deflector unit for columns in cold sea areas - has vertically oscillating ice-breaking body encircling column at sea level
Inventor: WAAS HEINRICH DR ING
IPC: E02B17/00
Filed: 1975-08-26
Abstract: The body can be designed to crush the ice (55) from above or break it up from below. In the former case the body has a conical lower surface (13) relative to the ice surface and is oscillated e.g. by a drive unit incorporating an eccentric. The vertical position of the body can be adjusted by a winch (30) whose lift cable incorporates an elastic coupling (35). The body is designed as an annular member which closely surrounds the column being protected. It is spaced from the column by four circumferentially spaced low friction guides at the top and bottom edges. Columns or pillars projecting above sea level in arctic waters can be endangered by forces exerted by ice forming on the surface of the water around them.

Title: Heat insulating soft PVC insole - with smooth side and fleecy or felt-like side
Inventor: BEHR WALTER DR
IPC: A43B17/14
Filed: 1975-10-31
Abstract: The insole for walking shoes, rubber botts and working shoes is made of soft PVC with a smooth side and side coated with plastic fibres which compacted to form a fleece or felt. The felt layer contains a high vol. proportion of finely divided air, for good heat insulation which can be increased by using several insoles one on top of the other. The insole is only 2.3 mm. thick. The insole may be worn with either the smooth side or the matted side facing upwards; in the latter case, the insole absorbs sweat which is useful for rubber boots in hot weather. The insole does not allow passage of moisture entering the shoe from underneath, can be washed in cold water, dries easily, is more tear- and wear-resistant when damp, and does not age.

Title: Air cleaning system for paint spraying booth - has dividing wall to direct air into water trough and facility for escape of air through slit
Inventor: HAFTSTEIN KARL
IPC: B05B14/44
Filed: 1976-05-11
Abstract: The paint spraying booth has a diving wall (1) which supportes a parallel plate (31). The plate (31) has staggered rows of diamond shaped holes. Water overflows from a channel (51) attached to the roof of the booth. Small droplets of surplus paint are carried by the airstream through the holes in the plate (31) into the gap (2). Water from the channel (51) washes the paint out of the air and falls into the trough (50). The air escapes through a narrow slit (10) between the dividing wall (1) and the water surface (50') and reaches the atmosphere through the filter (55). With this system the booth is adequately ventilated without exposing the operator to cold draughts.

IPC: F16L57/00
Filed: 1976-07-06
Abstract: Gas dust, esp. an exhaust gas duct for an internal combustion engine, where the inside wall of the duct has a ceramid linging (1) providing thermal insulation, esp. using a ceramic fibre mat; and the lining or mat (1) is covered on its surface with a thin layer (2) of metal or metal oxide. The ceramic fibres are pref. Al2O3. - SiO2, and layer (2) is pref. applied by plasma spraying and then smoothed or polished. The layers (1,2) pref. cover the entire inner wall of an exhaust gas manifold up to a gas purificn. device, e.g. a catalyst. Used e.g. on motor vehicles or on gas turbines, where the lining is not destroyed even when high gas velocities are involved so its thermal insulating properties are preserved. This is important because the gas should reach the catalyst at the highest possible temp.
