Class 3(2) In a box sign of the type provided with at least one panel of translucent material arranged to be illuminated from within the sign by means of one or more electric lamps, the body of the sign has substantially the shape of a wedge having plane rectangular sloping faces, equally inclined to a base and including between them an angle of between 22 degrees to 32 degrees, the base 1, the two ends 9 and at least the lower part of each sloping face being opaque and light diffusing on their inner surfaces but the greater part of at least one sloping face being translucent, means being provided for supporting within the body of the sign close to or parallel to the centre line of the base, one or more tubular electric lamps for providing a light source extending along not less than half the width of the sloping faces. The sign consists of a sheet metal channel shaped member 5 forming the base 1 and the two flanged metal end-plates 9 .are screwed to flanges 12 on the member 1. A. rectangular translucent sheet 2 of acrylic resin is bent to wedge shape and is fitted within the flanges 10 of the plates 9. The channel member 1 is provided with grooves 3 formed by welding metal strips 4 to the inner face of each longitudinal edge, these grooves accommodating the edges of the sheet 2. The apex of the sheet 2 is supported by a flange 13 attached to each end-plate 9. A tubular lamp 6 is supported in the base of the channel 1 and ventilation holes 16 are provided in the end plates and in the base. The sign may stand on feet attached to the channel 1 or be supported from eyes also carried by the channel 1. In a modification the acrylic sheet 2 only extends a short distance past the apex on one side and the gap between it and the channel 1 is filled by a detachable metal plate. The sheet 2 may have a design stencilled, painted or engraved on it.

Abstract: 643,343. Holders for discharge tubes. STANDARD TELEPHONES & CABLES, Ltd. Aug. 15, 1947, No. 22689. Convention date, Aug. 17, 1946. [Class 38 (i)] A cylindrical connector socket 1 for a valve pin 13 comprises a base 3 from which extend fingers 4 forming the socket proper 2. A threaded extension 5 projects from the base 3 to secure the connector socket on an apertured support 8. Short projections 7 forming a castellated edge for the base 3 extend at a greater radius opposite to the fingers 4 to provide fulcra, whereby the fingers are forced to tighten on the valve pin when a screw 11 is tightened in the extension 5 against a washer 12 over the support aperture 9. The width of the extension 5 is less than that of the aperture to permit the connector socket to be aligned with the inserted valve pin before tightening the screw 11. The support 8 may carry several connector sockets in a trefoil formation, Fig. 5 (not shown).

Title: An electrical switch having a quick-action switching mechanism
IPC: H01H5/00
Filed: 1962-06-13
Abstract: 962,362. Snap-action switches. FABRIEK VAN ELECTRISCHE APPARATEN VOOHEEN F. HAZEMEIJER & CO. N.V. June 13, 1962 [June 19, 1961], No. 22692/62. Heading H2B. Snap action is produced by torsional stress of a leaf spring, the movement of contacts being restrained until the spring is sufficiently stressed. When operating shaft 17 is turned a pin 19 on cam-plate 20 slides a plate 10 towards the position shown dotted, thereby moving lever 9 to twist one or more leaf springs 8. Two arms 6 (only one shown) are pivoted at 7 and secured to the ends of leaf spring assembly 8 as shown such that the torsion in the springs 8 tends to lift the moving contact carrier 1, but this is prevented by the member 13 abutting a locking plate 12. As plate 10 attains the dotted position, however, the cam 20 engages a pin 22 on plate 12 and moves the latter against the action of a leaf spring 15 to free member 13 so that contacts 2 are snapped away from fixed contacts 3. This releases the stress in springs 8, and when shaft 17 is released the spring 15 urges plate 12 into a recess 14 in member 13. The contacts 2 are thus retained in the open condition. When shaft 17 is rotated in the opposite direction the springs 8 are torsionally stressed in the reverse sense and when cam 20 engages another pin 22 the plate 12 leaves recess 14 and contacts 2 are snapped down into engagement with contacts 3.

The valve is used in suction or exhaust passages of internal combustion engines. The object of the angled seat is to overcome the seating difficulty at contact point (21), Fig. 1 (not shown), associated with the prior art. In alternative embodiments the support surface (22), Fig. 3 (not shown) may be part of the surface of the body around the port, the seat surface being at an angle thereto, also, the surface of seat (39), Fig. 4 (not shown) may be curved.

Class 80 (4) [Also in Group XXXII] A resilient mounting comprises a prism-like element 1 of rubber bonded on opposite pairs of sides to the respective re-entrant surfaces of two angle-bars 2, 3 connected to respective supporting and supported members (not shown) so that the weight of the supported members acts substantially transversely to the rubber element, the principal compressive elastic axis of the element being inclined to the direction of action of the weight at an angle of between 35 degrees and 55 degrees. Separate snubbing devices (not shown) may be disposed between the rigid members. As indicated by the dot-dash lines, two of the mountings disposed back-to-back, may be formed by the use of T and channel section rigid members. The end-faces of the resilient element are dish-shaped form. The rubber may have a shore hardness of 40-50 degrees and may be coated with a protective lacquer finish. Each mounting may be sufficiently long to carry a static load of 5,000 lbs. This will result in a static deflection of 0.7 ins. and natural frequency of vibration (vertical mode) of 4 c.p.s. The mountings may be disposed in pairs one on either side of the bedplate of a large, moderate speed, i/c engine.

The solution is preferably pre-purified of lipohilic impurities by extraction with a lipophilic water-immiscible organic solvent or a liquid ion-exchanger preferably in solution in a water-immiscible solvent, the extraction being carried out at about pH 2 to 7. The macroporous resin is preferably a styrene polymer crosslinked with divinyl benzene having an average pore diameter of 4-20 nm, preferably 7-10 nm such as "Amberlite" (Registered Trade Mark) XAD-1, XAD-2, XAD-4 and XAD- 5. The fermentation beer is preferably filtered and brought to pH 2-3 (e.g. with HCl, H 2 SO 4 , H 3 PO 4 , or oxalic acid) before treatment with the resin. The solution is passed through a column of the resin which is then washed with water; the adsorbed cephalosporin is then eluted with a mixture of water and a water-miscible organic solvent, e.g. 10-20% by volume isopropanol in water. The eluate may be further purified by adsorption on and elution from a basic ion exchange resin and then either precipitated from the final eluate (after concentration) as the free acid by adding a non-solvent (e.g. acetone or isopropanol) or isolated as a sparingly soluble complex with a heavy metal or as a salt. The macroporous resin may be re-generated for further use by washing with aqueous or aqueoussodium hypochlorite, followed by washing with acid or reducing agent (Na 2 SO 3 ; Na 2 S 2 O 3 ), and then with acetone.
