Title: A reversible ratchet wrench
IPC: B25B13/46
Filed: 1966-08-08
Abstract: 1,108,849. Wrenches. AUTO-UNION A.G., SAARBERGWERKE A.G., W. DOWIDAT, and H. M. DOWIDAT, [trading as DOWIDATWERKE WILLI DOWIDAT]. 8 Aug., 1966 [19 Aug., 1965], No. 35352/66. Heading B4W. A reversible ratchet wrench comprises a handle 1 formed with a head comprising an internally toothed ring 2, an insert 6 formed integrally with a box part 7 for engagement in a socket of a fastener, the insert being contained within the ring, and held against axial movement relative thereto by screw means 13, there being provided a control member comprising a toothed wedge 10 disposed between the ring 2 and an arcuate surface 18 of the insert, and arranged to engage the teeth on the ring, movement of the wedge between a first position in which only clockwise rotational movement of the handle is permitted and a second position in which only anticlockwise movement of the handle is permitted, being effected by a rotatable cover-plate and spring means, which act between the cover plate and wedge member. The insert 6 and the inner surface of the ring 2 define an opening 9 for the wedge member 10 which is supported on one side by a flat surface 17 of the insert, and on the other side by a spring 11. Axial movement of the insert is prevented by engagement of a flange 8 thereof with an end face of the head. The wedge 10 is arranged to rook relative to the insert 6 about either of two radiused corners thereof, thereby reducing sliding friction. Set screw 13 engages in a threaded bore in the insert, and in a central bore in the cover-plate 12. The spring 11 is a single spiral arranged between the cover-plate 12 and the upper face 14 of the insert 6, one end of the spring engaging in a bore in'the wedge member and the opposite end passing around a pin 27 which extends downwardly from the cover-plate 12 and is received in a segmental-shaped recess in the insert, so that the pin 27 forms a limiting stop. For clockwise rotational movement of the wrench, the cover-plate is moved into a position such that the limiting stop is in the position shown in full outline in Fig. 2, whereas for counter-clockwise rotational movement the cover-plate is moved into a position such that the stop 27 is in the position shown in chain line.

Abstract: 934,107. Embossing metals. MARK PERKS Ltd. Oct. 13, 1961 [Oct. 17, 1960], No. 35551/60. Class 83 (4). In a process for the patterning of a metal surface of a workpiece, the workpiece is assembled between a die and a planishing piece and the assembly is passed between co-operating rolls to press the workpiece on to an impression surface of the die, the portions of the die in relief being abraded such that a contrast is obtained on the metal surface between the rough area produced by the die and the polished or treated metal surface. The impression surface of the die may be etched, engraved, engine turned, blasted, or polished. As shown, a workpiece 10 is pressed by rolls between a die 11 and a planishing piece 12, the abraded portions 15 of the die impressing the workpiece while the grooves 14 allow the workpiece to remain polished in those areas. A plated workpiece, for example nickel and chromium plated brass, may be used, the resulting abraded areas being left untouched or etched, polished or replated. If anodised aluminium is used the metal after pressing may be etched, reanodised, dried or coated. Wire mesh, fabrics, or grained wood may be used to give patterning effects to the die.

Title: Brewing process and beer of low calorific value and extended resistance to haze development
IPC: C12C5/02
Filed: 1965-08-25
Abstract: In a process for preparing an alcohol-containing beer whose flavour is derived at least in part from the action of yeast on an aqueous extract of barley malt, and which process includes a mashing period followed by a fermentation period, amyloglucosidase is added to the materials being brewed to enable either one or both of the periods to be conducted in the presence of amyloglucosidase, the amount of amyloglucosidase added being sufficient to split at least 20% (preferably 80 to 100%) of the dextrins which would remain in the real extract without the use of amyloglucosidase.  The resulting beer typically contains less than 0.4 weight per cent of dextrins (instead of, say, 2.1-3.1%) and exhibits freedom from turbidity and haze when stored at ordinary ambient temperatures for a period exceeding six months.  A commercially available preparation of amyloglucosidase obtained from a culture filtrate from Aspergillus niger and admixed with diatomaceous earth may be employed for the purpose.  According to an example, specified proportions of an amyloglucosidase-containing preparation and yeast are added to a strained and cooled, hopped wort and fermentation is allowed to proceed.  The fermentation product is treated with a proteolytic chill-proofing enzyme preparation and is then bottled.  The beer remained clear for a year or more whether stored at ambient temperatures or at some time held under refrigeration.  According to the procedure of another example, a specified proportion of the amyloglucosidase preparation is additionally added to the mash in the mash tub.

Abstract: 1,068,526. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Sept 7, 1964 [Nov. 15, 1963], No. 36636/64. Heading G6C. In a pressurized water reactor the core is formed of fissionable rod assemblies, each of which is surrounded by a fertile blanket. Each assembly is subcritical in the absence of its blanket and there is no neutron coupling between the individual assemblies. During operation, the fissionable material in the assemblies is consumed and this is compensated by the fission of the fuel formed, during reactor operation, in the fertile blankets by the neutron flux from the associated assemblies. Each assembly consists of a central cylindrical section and an outer annular section. The former is movable axially within the latter to provide reactivity control. Each fissionable assembly contains some fertile material and this is distributed so that neutron flux from the fission material to the blanket fertile material is a function of the central section displacement. A safety element is insertable between the sections of each assembly. The coolant flow through the control sections of the assemblies is separate from that through the remainder of the core.
