Title: Detector for monitoring internal state of nuclear reactor - comprises sealed vessel contg. piezoelectric element against flexible wall of the vessel
Inventor: SHIRAYAMA SHIMPEY
IPC: G01N29/04
Filed: 1976-10-22
Abstract: Detector unit is located inside the reactor and supplies a signal giving information about the internal state. The signal is conducted to a signal processing unit. Detector unit comprises a sealed metal vessel, having one wall which can deflect inwards under external force. A piezoelectric element is in contact with the internal face of this deformable wall and thus supplies an electric signal corresp. to the magnitude of deformation of the wall. An electrode is in contact with the piezoelectric element and constitutes, together with the vessel, an electrode pair for transmitting the resultant signal. This pair of electrodes also defines an ionization chamber. In addition to the normal signals supplies from the ionization chamber giving a reading of the readiation in the reactor the electrode pair also supplies a signal giving an acoustic energy reading.

Patent DE-2705712-A1 (DE)
Inventor: FISSLER RUDOLF
IPC: A47J27/08
Filed: 1977-02-11
Abstract: To completely safeguard the lid-locking mechanism on a pressure-cooker in which pan and lid are to be connected with bayonet segments and in which the pressure relief and locking of the lid are functionally coupled, it is proposed that the safety valve (6, 7) have a movable valve body (7) which can be displaced between the rest position and the pressure-relief position. The bayonet segments (1a) of the pan (1) actuate a member (17) which can move the valve body (7) into the open position and can release it to take up the closing position. By this means, it is achieved that the pressure in the pan can also be reduced by intervention of the user. At the same time, the rubber seal is protected against continuous loading. The member acting on the valve body (7) is preferably a sloping plane situated on a tongue (17) and the tongue is the front part of a slide (13) which can be controlled by the bayonet segments (1a). <IMAGE>

Title: Hydromechanical deep drawing of metal sheet - uses two concentric punches for producing complicated shapes
Inventor: SPACEK JINDRICH DIPL ING
IPC: B21D22/20
Filed: 1977-03-17
Abstract: The deep drawing of metal sheet is carried out hydro-mechanically by using a pressure chamber (1) filled with oil (2) supplied through an inlet (3). The metal blank (5) is placed over the pressure chamber (2) which is sealed with a sealing ring (4). A pressure plate (6) which forms a guide for the main punch (10) holds the blank (5) in place. A second punch (8) slides in a hole in the main punch (10). The press pushes the inner punch downwards and forms a small cylindrical depression in the blank (5) until the flange (11) of the inner punch abuts against the end face of the main punch. The two punches then move together and form a larger cylindrical shape.

Title: Garden umbrella adjustable shelf - has slot for fitting onto umbrella stem, holding special clamp for height adjustment
Inventor: DIENER HORST
IPC: A47B57/26
Filed: 1977-07-01
Abstract: The shelf or tabletop (13) is detachably fixed to the centre rod (10) of a garden umbrella or chaiback rod by a support member (12). This engages at least partially from below in an opening (23) in the shelf. So that it can be threaded onto an upright rod which passes through the support member, the opening (23) in the shelf is preferably open axially along one longitudinal side so that the shelf can then be fitted onto the support. The shelf plate thus does not have its own base frame but is supported by the vertical centre rod. The shelf top can thus be set to the required height and any irregularity in the ground surface can be compensated for.

Title: Electrostatic dust precipitator - has conveyor belt on rising surface of outlet taper
Inventor: TASHIRO KOJI
IPC: B03C3/88
Filed: 1977-07-23
Abstract: The design improves the efficiency of horizontal electrostatic precipitators by recapturing dust deposits forming on conventional designs on the inclined bottom surface of the outlet tapers, where the increased air velocity causes turbulence and carries away the deposited dust into the clean side. The taper (3) fitted to the outlet end of the precipitator connects on its reduced end to the ducting (2) carrying the cleaned air. The design proposes to fit on the inclined surface (4) of the taper a belt conveyor (7) rotating in such a way that the top end of the belt moves down the slope carrying collected dust towards roller (5) where the dust is removed by skimmer assembly (8) from where it drops into chute (9).

Title: Cleaning system for tanks and vessels - using spray cleaner with strainer vessel on liquor return line having automatic cleaning cycle
Inventor: KAUF HANS DIPL ING
IPC: B01D37/00
Filed: 1977-10-05
Abstract: Cleaning system has series of wash liquor vessels, the contacts of which are pumped to the rotating spray head.

Title: Slip measurement device with direct indication - operates using pick=ups generating pulses induced by belt and pulley markers
Inventor: FLORUS HANS JOERG DIPL ING
IPC: G01P3/56
Filed: 1977-12-13
Abstract: A device for measuring slip, esp. between a V-belt and a drive motor pulley, enables the desired parameter to be read off without a process of calculation and hence permits almost instantaneous slip value measurement. The belt carries a marker inducing pulses in two pick-ups arranged at a defined angle and connected to the pulley shaft bearing. A disc rotating with the pulley also carries a marker inducing pulses in a third pick-up. The outputs of circuits measuring the belt and disc angular rotation times are processed to indicate slippage.

Title: Pusher type centrifuge - with diffusor on solids discharge and return channel for gaseous media
Inventor: CHRIST ALFRED DR
IPC: B04B11/02
Filed: 1977-12-21
Abstract: A pusher-type of centrifuge includes a solids space contg. a gaseous medium. The discharge pipe from the solids space represents a diffusor. The outlet end of the diffusor is joined through a return channel to the solids space. The amount of gaseous medium, present in the solids space, is thus reduced as little as possible by the solids extraction. This eliminates the detrimental pressure differential and maintains the gaseous medium in its state.
