Title: Moulding process
IPC: B28B7/00
Filed: 1980-10-22
Abstract: An apparatus for producing a building block includes a mould box (13) which can rest on a board (10). Within the mould box is a frame (14) which at its lower and has bars (18). Stops (17) are provided to position the frame relative to the board. A semi-dry mix of material is loaded into the mould box and frame and is compacted using vibration assisted by a tamper plate (22). When compaction is complete the mould box (13) is moved away from the surface of the board so that the lower edge of the mould box lies above the lower edge of the frame. The frame (14) and the tamper plate (22) are then lifted away from the surface and the compacted mass fractures along a plane defined by the bars (18). The board is then removed with the compacted mass which is allowed to cure.

Title: Method of producing solid electrolyte oxygen-sensing element of laminated structure with measuring electrode partially deposited from vapor phase
IPC: G01N27/409
Filed: 1981-07-20
Abstract: A method of producing an oxygen sensing element of the concentration cell type in the form of a lamination of relative thin layers. The first step of the method is to prepare a lamination of a ceramic shield layer (12) which serves as a substrate, an inner or reference electrode layer (16), an oxygen ion conductive solid electrolyte layer (18) and an outer or measurement electrode layer (20) which is porously formed by sintering an electronically conducting powder, preferably a cermet powder, applied to the solid electrolyte layer surface in the form of paste. To improve the responsiveness of the oxygen sensing element, an additional measurement electrode layer (24), preferably not thicker than 0.5 microns, is formed on the sintered measurement electrode layer (20) by a physical vapor deposition technique such as sputtering, ion plating or vacuum evaporation by using a mask formed with an opening through which only the outer surface of the sintered measurement electrode layer is exposed. <IMAGE>

Title: Thermal Shield Plate Construction for Heat Exchanger
IPC: F28D7/16
Filed: 1981-08-24
Abstract: A thermal shield plate construction for a heat exchanger for cooling a fluid of high temperature used with a cooled type fast neutron breeder reactor, which is used for providing a protection from heat to welds formed between heat exchange tubes (9) and tube sheets (4, 8), and comprises thermal shield plates (11) each split at least radially into a plurality of pieces of the thermal shield plates, with end portions of the adjacent pieces being formed with stepped portions (21) respectively, which, when superposed one over the other, have the same thickness as the thermal shield plates (11). The structural features can avoid the disadvantages of the prior art namely that the effects achieved in shielding the parts from heat are reduced by the fluid of high temperature seeping through the gaps between the thermal shield plates and that excessively high stress is produced in the welds between the heat exchange tubes and the tube sheets. <IMAGE>

Title: Stabilising a transducer output
Inventor: LEES ROGER THOMAS
IPC: H01J29/98
Filed: 1981-12-03
Abstract: The output delivered by a transducer e.g. a cathode ray tube (10) having an integral power law transfer characteristic is stabilised by controlling output signal components related to the operating bias and gain of the transducer circuit. A test input signal comprising a sine-wave is applied (18) to the transducer. The fundamental and integral harmonic components are filtered (26, 28) from the resulting output signal. The transducer is stabilized by restoring in sequence the amplitude of the harmonic and fundamental components to predetermined values respectively related to desired operating gain and bias conditions. A typical transducer is a cathode ray tube. <IMAGE>

Title: Microtome having a forward-feed control system for the specimen arm and/or the knife
Inventor: SITTE DR HELMUTH
IPC: G01N1/06
Filed: 1983-06-23
Abstract: A microtome, especially an ultramicrotome, is disclosed in which a foward-feed system for the specimen arm and/or knife of the microtome comprises, a stepping motor which is controlled by a pulse generator and which shifts the specimen arm and the knife relative to each other by an appropriate amount of forward-feed in accordance with a forward-feed value which is set at one of a plurality of preselector switches. In order to facilitate quick switching-over from one forward-feed amplitude to another, permitting the selection of forward-feed amplitudes which differ by an order of magnitude, for example if semi-thin sections are to be produced during a run of ultra-thin sections, the forward-feed amplitudes set by the preselector switches can be switched according to choice to the pulse generator for the stepping motor, by means of a changeover switch. This arrangement enables the operator to alter the forward-feed amplitude by one manual action, without disturbing the ongoing operation.
