Title: Displacement transducer for fracture toughness tests on metals - uses two rigid arms joined at one end by spring link to which strain-gauges are attached
Inventor: BACHMANN VOLKER ING GRAD
IPC: G01B7/16
Filed: 1977-11-11
Abstract: The displacement transducer consists of two rigid arms (18, 19) whose inner ends are inserted into the standardized starter notch of the material sample under test (14). The outer ends of the arms are coupled together by a flexible strip or spring (20) which expands the arms so that their inner ends grip the knife-edges of the starter notch (17). The inner and outer faces of the spring are fitted with stain-gauge strips (21, 22) to form an electromechanical transducer. The strain-gauge elements are connected to a measuring bridge (23) in the usual manner so that the flexural loading of the spring strip may be observed (24). The displacement transducer is suitable for fracture measurements on materials (plane strain fracture toughness of metals.

Title: Toy steam locomotive with remote speed control - uses electric heating of bimetallic strip to open regulator valve admitting steam to cylinders
Inventor: HIELSCHER LUTZ
IPC: A63H29/16
Filed: 1978-02-08
Abstract: A toy steam locomotive has a boiler (101) from which the steam passes out through a sleeve (34) into a chamber (29) and then flows down a tube (18) to a ball valve (14). The ball valve is held closed by a bimetallic strip (44) which is straight and horizontal when cold. The bimetallic strip (44) can be heated by an electric element (48) with a variable current supply. Heating the bimetallic strip (44) causes it to bend and allow the ball valve (14) to open so that the speed of the locomotive can be controlled by varying the current using the same control system as for electrically driven models.

Title: Beer tap column with refrigerator - adds carbon di:oxide to beer and is controlled as function of beer temp.
Inventor: MICHALEK RUDOLF
IPC: B67D1/12
Filed: 1978-06-24
Abstract: The condition of beverages such as Pilsner beer which is dispensed through a tap from a barrel, perssurised by CO2, is controlled by adjusting the pressure head continuously as a function of the actual temp. of the beverage. The temp. is measured in the barrel or after a pass-through cooler and the pressure adjustment takes into account a correction factor for the piping. The tap column houses in the bottom compartment the beer barrel and CO2 bottle, also the evaporator of the refrigerator. The compressor and condenser of the latter are accommodated in the next higher compartment. The top includes a printed circuit board (30) with a thermostat (34) which can be adjusted by a knob (38) to the desired temp. of the beer in the barrel. Two digital displays show the actual temp. and CO2 pressure.

Title: Resilient sports hall floor - is of multilayer construction with non-diffusing low moisture absorbent foam layers and adhesive layer
Inventor: REUTHER RICHARD
IPC: E04F15/22
Filed: 1978-07-21
Abstract: The flooring is esp. designed for sports halls and gymnasiums. There are layers, from the bottom up, of spaced compressible spring element pieces, solid insulating panels, wood chip panels set in two layers, and a thin intermediate layer. The spring element pieces (10) are made from elastically compressible plastics foam material, with min. water absorption and moisture diffusion. The thin intermediate layer (6, 8) is an adhesive layer completely covering the bottom wood chip panels (7) with glass-fibre, while the bottom wood chip panels are firmly connected to the insulating panels (9) which are of material similar to the spring element pieces. While retaining good spring and resistance to fracture, this checks penetration of moisture from below.

Title: Agitator shaft for immersion in corrosive liquids - having protective sheath around hollow shaft with three bearings and flexible seal coupling
Inventor: STREICHER MAX
IPC: B01F7/00
Filed: 1978-11-11
Abstract: Pumping device has a rotor immersed in a liquid. The rotor is driven by a shaft passing through the liquid surface supported in a set of bearings mounted in a support arm. The shaft is protected by a rotating sheath which extends well above the liquid surface and which is connected to the support arm via a roller bearing. A further tubular sheath protects this bearing against liquid spray. The inner sheath is mounted on the central shaft with flexible couplings to keep it centred. Used esp. for aeration or submerged pumping of corrosive effluent streams. The precise location and centering of the shaft not merely protects the bearings against corrosion but also reduces the mechanical damage due to vibration etc.

Title: Extruded aluminium girder production system - uses two separate angle sections joined together to give greater web height
Inventor: LAYHER EBERHARD
IPC: E04C3/06
Filed: 1978-11-25
Abstract: The system produces angle-section girders of extruded aluminium of aluminium alloy. Two separate angle sections are first produced, their external dimensions being such as not to exceed the max. dia. permissible for extrusion nozzles. Their shape is such that they can subsequently be assembled together to form girders of larger web height, or a lattice-work structure. To form an 1-section girder, two T-sections can be produced, each having a narrower tongue along the free edge. The sections are then assembled together with the inner tongue faces against each other and joined together.
Patent DE-2855866-A1 (DE)
Inventor: HEUBER KLAUS DIPL ING
IPC: H01L27/02
Filed: 1978-12-22
Abstract: In integrated semiconductor memory cell arrangements, particularly integrated semiconductor memory cell arrangements using merged transistor logic configurations, line capacitances are discharged before accessing to reduce access time and power consumption. Individual bit line transistor switching means are coupled to each bit line to provide a discharge path for the line capacitances associated therewith. Common transistor switching means are coupled to each individual bit line transistor switching means to commonly discharge the individual discharge currents received from each individual bit line transistor switching means. Individual word line transistor switching means are also connected to respective word lines to distribute the current passing through the common transistor switching means to the respective word lines. The discharge circuit arrangement permits minimum-area bit line and word line transistor switching means.

Title: Swivelling gate drive system - has gliding link end rigidly connected to leaf enclosing angle of 90 degrees with arm
Inventor: LEHMANN SIEFRIED
IPC: E05F15/63
Filed: 1979-03-08
Abstract: The leaf (5) is operated by an electric motor (6) via a shaft (7) using a link (8). The free end of the link (8) carries a roller (9) gliding in guide rail (10) rigidly connected to the arm, which, in turn is mounted on the gate leaf (5).
