Title: Peristaltic pumps
Inventor: CUMMINS DONALD L
IPC: F04B43/12
Filed: 1982-09-23
Abstract: A pump for a viscous fluid such as dough, has a rectilinear pumping- tube 37 that is compressed between a fixed surface 21 and perpendicularly reciprocating shoes 40 ... 46, the latter being driven by e.g. gear-wheels 70 ...76 through links 60 ... 66. To minimise back-lash the gear-wheels are driven simultaneously by motors 80, (85), Fig. 4 (not shown), coupled to the outer gear-wheels 70, 76 through further gear-wheels (82), 87. To facilitate inflation of the tube 37, a chamber 17 may be evacuated by vacuum pumps (81, 86) driven by the motors. Alternatively, the tube 37 may be reinforced with resilient wire. <IMAGE>

Title: Thermosetting adhesive compositions based on an epoxy resin
Inventor: SHIOW CHING LIN
IPC: C09J4/00
Filed: 1982-09-29
Abstract: The invention provides an ethylenically unsaturated linear or cyclic reaction product of an acrylate or methacrylate ester of an epoxy resin containing at least one, and preferably two, hydroxyl groups and a polyisocyanate, preferably a diisocyanate. The solid compound in combination with a free radical thermal initiator can be used as an adhesive by heating to relatively low elevated temperatures, e.g. 60-100 DEG C, whereat it becomes soft and fluid with good wettability of the material to be adhered, and subsequent higher heating, to trigger the free radical thermal initiator, results in a thermoset adhesive bond.

Patent GB-2146932-A (GB)
Title: Power turning device
Inventor: WAGNER PAUL-HEINZ
IPC: F16H1/46
Filed: 1984-08-06
Abstract: The power driven rotary tool has a housing part (11) in which a single or multi-stage main gear (8,9) is housed. A housing part (12) containing an additional gear stage (28) is detachably fixed to the input side of the housing part (11). A first input shaft (25) leads through the additional gear stage (28) to the input stage of the main gear (8, 9). A second input shaft (30), forming the input shaft of the additional gear (28), extends co-axially to the first input shaft (25). The output part of the additional gear (28) is coupled with the first input shaft (25) so as to be secure against rotation. By fixing a tool to coupling components (27, 31) at the free ends of the input shafts (25, 30), various transmission ratios of the whole gear can be selected. The transmission ratio can also be altered under load. As both input shafts (25, 30) extend co-axially to the output shaft (4), the output torque is always proportional to the input torque. One of the input shafts is hollow. <IMAGE>

Title: Electrochemical cell having controlled electrolyte flow
Inventor: HOLMES JOHN PETER
IPC: C25B11/00
Filed: 1984-09-21
Abstract: An electrochemical cell has an annular flow passage for electrolyte solution. The cell is designed such that, in an intermediate zone, the passage is of constant cross-section (to achieve high electrolytic activity) and, in end zones, the passage progressively increases in cross-section to a maximum value (to lower the current density in regions in which unwanted deposition of salts may preferentially occur). The cross-sectional shape of the passage along its length also assists in reducing turbulence in the flow thereby reducing the rate of deposition of salts. Owing to the low rate of deposition, it is possible to maintain the electrodes relatively clean by current reversal at relatively infrequent intervals. That enables the cell to be used for longer periods between cleaning operations.

Title: Cryostat for operation of a <3>He <4>He mixing unit
Inventor: HEERINGA WABE
IPC: F25J1/00
Filed: 1985-08-20
Abstract: This invention relates to a cryostat for operation of a <3>He-<4>He mixing unit. A preferred method of generating temperatures in the mK range consists in diluting liquid <3>He into liquid <4>He in a <3>He-<4>He mixing cryostat. In the familiar systems the mixing chamber of the <3>He-<4>He loop is located in a 1 K pot which, by means of <4>He contact gas is brought to 4 K and by evacuation of the <4>He to about 1 K level. Precooling, especially elimination of the contact gas, is very time consuming. Deviating from the familiar and usually employed cryostats, this invention substitutes a 2 K beaker 7 provided below the 4 K pool 4 for the usual 1 K pot and provides the mixing unit 8 with a precooler pipe 12. In the 2 K beaker 7 the helium is transformed into the superfluid state by an evaporator 19 and, consequently, cooled down to 2.17 K. <IMAGE>
