Title: Bolt or stud tensioning
IPC: B25B29/02
Filed: 1974-02-18
Abstract: 1492064 Tensioning bolts DONCASTERS MOORSIDE Ltd 12 Feb 1975 [18 Feb 1974] 7194/74 Heading F2H To pre-tension a series of bolts or studs 10, e.g. a ring of bolts or studs on a steam turbine casing, a plurality of yoke members 18 are provided each of which is supported by a cap spacer 28 about a respective bolt or stud 10 and each of which is coupled to two adaptors 32 engaged with the flanking bolts or studs such that force applied to the yoke members 18, e.g. by hydraulic piston and cylinder arrangements 20-26, is effective to pre-tension the flanking bolts or studs. After the stub 14 on the flanking bolt or studs have been tightened then yoke members 18 can then be moved so as to be supported about the flanking bolt or studs in order to pre-tension the remaining bolt or studs. Thus the circular series of studs shown can be pre-tensioned and their nuts 14 tightened by a ring of yoke members in only two operations. As shown the yoke members 18 have grooved ends 34 so that each adaptor 32 is gripped between the ends of two adjacent yoke members 18. Alternatively the adaptors 32 may pass through holes in the ends of the adjacent yoke members, with the yoke members being in staggered relationship. The cylinders can, as shown, be supplied from a common pump 42 or, as in Fig. 5 (not shown), from separate hydraulic pumps (44) powered by a common pressurized air source (46).

Abstract: 540,649. Manual exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and LOWRY, L. P. April 23, 1940, No. 7313. [Class 40 (iv)] A substation associated with a barrageballoon post includes contacts controlled by a wire tension indicator for sending a signal to the exchange in the event of the balloon wire becoming too taut or too slack. The substation preferably employs magneto calling, and the indicator contacts AIC connect battery across the line wires to operate the drop indicator DI, or, as shown in Fig. 2, connect battery to one wire, the drop indicator being in this case doublewound and grounded at its mid-point over a key ADK which permits simple disablement of the signalling circuit.

Title: Improvements in or relating to friction clutch-plates
IPC: F16D13/68
Filed: 1938-03-10
Abstract: 491,708. Clutch plates. BORG & BECK CO., Ltd. March 10, 1938, No. 7536. Convention date, April 22, 1937. [Class 80 (ii)] A driven clutch plate comprises a carrier disc, stamped from a single piece of sheet steel, and formed with an inner rim 12, riveted to a splined hub member 2, a set of spokes 9 extending from the rim 12 to an outer annular rim 8, and another set of radially-bowed and circumferentially-flexible spokes 11 extending from the rim 12 to sections 10 which are severed from the rim 8. The sections 10 taper outwardly, so that, due to the bowing of their spokes 11, gaps are provided between the edges of each section and the adjacent edges of the recesses in the rim 8. Friction facings 5 are riveted only to the sections 10 and bear frictionally against the rim 8. Torque applied to the facings 5 is thus transmitted to the hub in part through the resilient spokes 11 and in part by friction through the spokes 9. Such friction also serves to damp out vibration, and may be augmented by bowing each section 10 and the radially-adjacent part 18 of the rim 8 as shown in Fig. 5. When excessive torque is being transmitted, the leading edges of the sections 10 contact with the adjacent edges of the recesses in the rim 8, whereby damage to the spokes 11 is prevented.

The platform may be made up of a number of platforms provided with means of attachment, to each other for example by means of pin hinges, or to the pivot for example by means of rings. Certain of the platforms may be detachable and replaceable by others.

Heading C2C. #-Caprolactam or #-laurolactam is prepared by contacting in the vapour phase nitrocyclohexane or nitrocyclododecane with a catalyst containing metallic lead or a lead oxide at a temperature of from 180-450 C. The lead or lead oxide catalyst may be used supported on a carrier or in admixture with a carrier. Such catalysts may be obtained by impregnating or precipitating an aqueous solution or suspension of an inorganic or organic acid salt of lead in or with a carrier which is a solid acid, an oxide of a metal except lead belonging to Groups I B -I V  of the Periodic Table or a metal belonging to Groups VI-VIII of the Periodic Table, a double salt thereof or a complex salt thereof, drying and then heating the impregnated or precipitated product to a temperature of from 200-1300 C. Suitable solid acids are acid clay, acid-treated acid clay, fuller's earth, bentonite, silica, alumina, and silica-alumina. The reaction may be carried out in the presence of a non-oxidizing gas such as nitrogen, carbon dioxide, helium or argon or a reducing gas such as hydrogen or carbon monoxide, these gases acting as carrier gases for the nitrocyclohexane or nitrocyclododecane.

A carbonated beverage e.g. beer is drawn through a filter 1 by a pump 3 which forces the beer through a heat exchanger 2 to bring it to pasteurization temperature before being supplied to a back pressure filler 5 to fill bottles emerging from a washing machine 7. The bottles are sealed by the machine 8 and cooled at 9 before being labelled at 4. The pump 3 is such that it delivers a substantially constant pressure of liquid to the heat exchanger regardless of the output therefrom and the exchanger operates at only a slightly higher temperature than the heated beverage. With this arrangement it is stated that if the liquid flow from the heat exchanger is interrupted then the beverage therein is unaffected since pressure and temperature remain substantially the same.
