Title: Furniture element for built-up furniture units - can be different depths but has height one third of length for greater versatility
IPC: A47B87/02
Filed: 1975-01-21
Abstract: The furniture element which is intended to combine with further elements to form unit furniture comprises a frame the height of which equals a third of the length. The four walls of the frame each have at least one pair of connecting holes, with the spacing between the two holes of each pair being the same so that when the elements are combined they can be secured by means of pins etc. The base member and top of the frame preferably have three pairs of connecting holes whilst the distance between the back wall of the frame and the row of holes adjoining this wall is preferably larger than the distance between the front side of the frame and the row of holes adjoining this side. Since the depths of the elements may differ it is possible to obtain a unit with a common back wall whilst the front side is stepped.

Title: Air lock e.g. for electron beam welding machines - using two rubber walls between rotating and stationary machine parts
IPC: H01J37/18
Filed: 1975-03-25
Abstract: Device for maintaining a seal between a stationary part and a moving part is claimed. The novelty is the use of two flexible walls reinforced by rigid internal structures which can resist pressure, and the rigid structures are displaced w.r.t. each other in a controlled manner when the flexible walls are deformed. In one pref. device, two corrugated walls made of an elastomer are located on the stationary part, the bottom end of each wall terminating in a flap, and the flaps are alternately forced by springs against the joint surface on the moving part so that at least one flap forms a seal at any moment of time. A vacuum tight seal can be achieved without very accurate machining of the parts, e.g. on machines used for electron beam welding in mass prodn.

Title: Fitting for fixing antenna mast to chimney top - has two L:shaped metal plates with plates with holes in angled flaps to hold mast
IPC: H01Q1/12
Filed: 1975-11-03
Abstract: The fitting, for fixing an antenna mast to a chimney top, requires no special tools and is made from two identical metal sheets. Each metal sheet (3) has an L-shape with a rectangular slot (6) in and an orthogonal flap (4) bent out of its larger arm. Its shorter arm is blank. A second flap (14) is formed in the same plane as th e first and at right angles to a stub (13) projecting at right angles from the plane of the L. Both flaps have holes (5,15). When the two Ls are brought together the second flap of one L passes through the rectangular slot of the other. The planes of the Ls are therefore at right angles. The mast passes through the hole in one L's first flap and through the hole in the other L's second flap.

Title: Heating and refrigeration system - has heat source acting on refrigerating medium between condenser and expander
Inventor: FILLIOS JEAN-PIERRE
IPC: F25B29/00
Filed: 1976-01-15
Abstract: The heating and refrigeration system circulates a refrigerating medium in succession through a compressor, a condenser, an expander and an evaporator, the medium being exposed in the latter to a heat source. The heat source is caused to act on the medium after it leaves the condenser and before it reaches the expander. This gives simultaneous extra refrigeration of the condensed medium and heating of the heat source. For this purpose there can be a heat exchanger between the medium at the evaporator outlet and at the condenser outlet, that between the medium and the heat source being upstream of this exchanger.

Title: Planing machine cutting blade setting device - has blade carrier roller supported under cross piece and blade adjusted upwards by spring underneath
IPC: B23Q17/22
Filed: 1976-06-09
Abstract: The device is for setting the height of the blade (17) of a cutter for a machine such as a planing machine.

Title: Oxygen analyser using paramagnetic property - having two thermomagnetic pressure inducers with pressure sensor between (BE170177)
IPC: G01N27/74
Filed: 1976-06-30
Abstract: Device for determining the O2 content of a gas mixt. measures the pressure difference induced by two non-homogeneous magnetic fields through which the gas passes in a heated section of line. The pressure difference induced by the two fields react against each other. This pressure is measured in a branch line from the gas line contg. an auxiliary gas. The gas line can split into two parallel branches one of which is led through a pair of magnetic fields induced by a pulsing electric current. The auxiliary gas is then fed into both streams and either its pressure or flow measured. The auxiliary gas can be air. The flow of sample gas to the flow of air is in the ratio of 1000:1. Used for the industrial measurement of the O2 content of gas streams. The auxiliary gas flow is just enough to prevent the sample gas diffusing down to the sensor.

Title: Extruded plastic sealing strip - is for doors or windows and has soft lip attached to hard serrated body (SF 31.5.78)
Inventor: EGGERT FRANK
IPC: F16B5/12
Filed: 1976-09-30
Abstract: A sealing strip or weather strip for doors or windows is made of extruded plastic. The body (1) is made of relatively hard plastic and has an arm (5) with serrations (2) on its outer surface. A lip (4) of relatively soft plastic is bonded to the inner surface of the arm (5) when the two sections are extruded together. The width of the lip (4) is considerably greater than the width of the groove in which the strip is fitted. The soft lip (4) is thus deformed when fitted into the groove of a door or window and so provides an efficient seal. At the same time the harder serrations (4) bite into the wall of the groove so that the strip cannot be easily removed.

Title: Double rotary hydraulic motor in which two 40cm<2>, rectangular blades P1 and P2, offset by 180 DEG , utilise the pressure of one kilo per square centimetre for 324 DEG before being driven by the other motor in order to make use, in equal measure, of the remainder of the rotation for closure of the feeds before the idle period which precedes the return of the same cycle
IPC: F03B17/00
Filed: 1976-11-09
Abstract: Double rotary hydraulic motor, the rectangular blades P1 and P2 of which, offset by 180 DEG , successively receive, from a pressure of one kilo per square centimetre and in each motor cylinder, a thrust of 40kg to 80kg for 5 DEG , another of 13kg to 40kg for 67 DEG , for a first rotation of 72 DEG , followed by this same thrust for 180 DEG and then finishing with a final thrust of 40kg to zero, after a rotation of 72 DEG bringing about the closure of the exhaust, after a positive rotation of the shaft for 324 DEG and before, passively driven by the second motor, each for 18 DEG , the closure of the feed and the idle period which concludes each driving rotation. The simultaneous stoppage of the two feeds can be easily accomplished by the manually controlled displacement of a cylindrical segment clearly exceeding the 180 DEG to remain touching the internal curvature of the cylinder containing the common exhaust, in order to vary the output and the corresponding powers or, more frequently, to arrest the functioning thereof.
