Title: Foundry moulding box - with four flanged track wheels attached in pairs to each moulding box for transport
Inventor: MEIRITZ LOTHAR ING GRAD
IPC: B22C21/12
Filed: 1978-03-28
Abstract: A moulding box for foundries consists of an upper box and a lower box, joined by clamps, which are conveyed on tracks through the foundry by transporters. The wheels for transport are attached directly to the four corners of each box, with the centre line of each pair of wheels lying in the central plane of the lower box and preferably also of the upper box. This saves the heavy carriages or pallets, normally used for the transport of the moulding boxes. The tracks can be lighter and there are less vibrations during transport to cause moulding sand spillage. The saving in height means lower cooling tunnels.

Patent DE-2841761-A1 (DE)
Inventor: SPORKENBACH GUSTAV ADOLF
IPC: C04B38/06
Filed: 1978-09-26
Abstract: Plate-shaped or grid-shaped insert elements (4, 6; 5, 8, 9) consisting of expanded clay, for example, are introduced into the cavities (3) of a clay frame (1, 2). For rapid and uniform expansion, opening materials of spherical form are mixed into the material of the insert elements. Dimensions and expandability are selected such that the porous or cellular structure resulting from subsequent burning out of the insert elements fills the cavities until at least close to the end sides of the block. The lightweight block, which is made sufficiently strong by the frame (1, 2), avoids any air circulation in the masonry structure and has favourable heat-insulation values. <IMAGE>

Title: Elastomer support pads for building components - with parallel triangular ribs of different size on the two sides
Inventor: BATTERMANN WALTER
IPC: E04B1/36
Filed: 1979-01-19
Abstract: Non-reinforced pads of elastomer have found ready acceptance in the building industry to compensate for slight surface and alignment inaccuracies and to act as protection against the ingress of moisture and the transmission of vibrations. It is now suggested to provide parallel triangular ribs on both sides of the support strips of natural or synthetic rubber. The ribs on one side are much larger than those on the other side, with the base of the large triangles covering, e.g. three bases of the small triangles. The strips can be assembled either with the small triangles facing each other, or with the large triangles in contact to suit different applications. The pref. Shore hardness is 50 - 70 A. Varying elasticity makes the strips usable more universally.

Title: Push button selection keyboard for telephone set - has two orthogonal sets of conductors with L=shaped lateral arms acting as spring-contact crosspoint switches
Inventor: GEESE ALBERT
IPC: H04M1/23

The strips in the first set have lateral L-shaped arms (9) projecting from them and acting as leaf-spring contacts. The push-buttons (8) are located above the ends of these arms and, when depressed, press the ends of the arms down onto the corresp. conducting strips in the second set of strips immediately below. The arms therefore act as crosspoint switches. Needs no separate contact plates and offers simplicity but with reliability and versatility.

Title: Game installation using compressible air - consists of liq. container with floating swim element movable by adjustment of its buoyancy
Inventor: SEEFLUTH UWE C
IPC: A63H23/08
Filed: 1979-04-04
Abstract: The game installation consists of a liq. container which is at least partly transparent. It contains a free floating swim element which is movable by adjustment of its buoyancy. The buoyancy of the swimming element is adjusted by the compression of an air bubble positioned inside a hollow chamber of the swim element housing using pressure devices in the liq. container. The extension of the air bubble or of the air space inside the swim element also produces a recoil effect in a horizontal direction through the liquid flowing out from the swim element housing.

Title: Motor vehicle wheel suspension - has front axle shock absorbers and flow restricted by=pass linked to brake line
Inventor: BUFLER ERNST DIPL ING
IPC: F16F9/46
Filed: 1979-04-12
Abstract: The stabilised front wheel damper is linked to the front wheel brakes to harden the damper reaction during braking and to prevent the front of the car from dipping. The brake pressure operates a flow restriction (2) in a bypass to the damping piston (3). The flow restriction has a valve element (2) normally held in the open position. Brake pressure forces a piston against a spring and progressively shuts off the shunt line (4) between the top and bottom of the damper. An alternative layout has bulkhead in one of the damper chambers, containing the flow restriction valve. During braking an increasingly smaller damper volume is available with a resulting harder reaction.

Title: Displaceable inspection guide for nuclear pressure vessels - with vertical alignment of rope suspended guide rail and carriage
Inventor: SEIFERT WALDEMAR ING GRAD
IPC: G21C17/007
Filed: 1979-05-04
Abstract: A displaceable guide for an inspection system on pressure vessels of nuclear reactors consists of a guide rail which can be fixed to the pressure vessel wall by four electro-magnets. The guide rail is suspended from a crosspiece on two ropes, and the carriage with the pickups which runs along the guide rail hangs on another rope. An angular telescope is used to line up the guide rail vertically by two crosshairs fixed to it. This inspection system can be used for older existing nuclear power stations where a fixed installation is impossible because of high radioactivity or adverse geometric dimensions.
Patent DE-2922022-A1 (DE)
Inventor: MOTSCH HANS
IPC: A47J31/44
Filed: 1979-05-30
Abstract: If collection containers (8, 9) of different sizes, such as pots or cups, are to be filled alternatingly on a coffee machine, a vertically adjustable platform (6) is necessary under the infusion unit (3). In known coffee machines, in order to make an adjustment a vertical relative movement is effected between a recess and a rod-shaped part passing through the latter with play, and a clamping screw is provided for fixing the position. Loosening of the screw, displacement and renewed fixing requires two hands and is time-consuming. According to the invention, both the recess (5) and the rod-shaped part (7) have in each case an oval cross-section. The dimensions of the cross-sections permit a displacement position with play between recess and rod. A clamping position between rod and recess is achieved in a simple manner by turning the moveable part about a vertical axis. Turning, displacement and turning back can be carried out quickly and safely with one hand using a handle (10). One hand remains free for the collection container. The turning movement into the clamping position can be carried out automatically with the aid of a spring. <IMAGE>
