Filed: 1972-08-25
Abstract: 1398538 Illuminated display WERBELICHT KG RUDOLF JEROMA 25 Aug 1972 39777/72 Heading G5C [Also in Division F4] An internally illuminated display unit comprises a tray 1 containing fluorescent tubes 24 which has an inwardly directed beading 2 around its rim and a translucent cover 6 which carries the display and has around its rim an outwardly facing groove 5 in which the beading 2 clips. The extent to which the beading 2 projects increases from the corners of the tray 1 to the mid-points of the sides which are resilient and initially concave, enhancing the seal between the cover and the tray. Any water penetrating into the groove 5 is attracted by capillary action through a narrow opening 11 into a space 9 provided with drainage holes. A groove 14 around the face 12 of the cover traps any water that might run down the sides of the cover. A transparent foil internally sealing off the cover from the tray may be provided secured to the limb 4 of the groove 5. The foil may have corrugations or pyramidal protrusions to diffuse the light. Each socket (23), Fig. 10 (not shown), may have a resilient insert to retain the pins of the tube 24, and a protective cap (28). The unit may be fitted to horizontal or vertical bars by two perpendicular sets of hooks 15, 16 and is provided with grooves 20 along two adjacent sides and with tongues 21 along the other two. Units may be joined by inter-engaging tongues and grooves or by using bars 22 between two grooved sides. Units of various shapes and sizes are provided.

Abstract: 1350792 Multi-disc brakes; automatic adjustment; actuators LAMBERT BRAKE CORP 25 Aug 1971 [10 Sept 1970] 39938/71 Headings F2E and F2F A multi-disc brake assembly 10 is energized by operation of an actuator plate 50 and the plate 50 incorporates automatic adjuster means 76 which act to adjust the retracted position of the plate 50 so as to compensate for wear in annular friction pads 44, 46, 48: the adjuster means 76 comprises a pin 78 extending through counterbores 81, 85, 87 defining an opening 80 in the plate 50 and having its respective ends adapted to abut first and second surfaces 86, 60 on a housing 22 of the assembly 10 to define retracted and advanced positions of the plate 50 respectively, a one way washer assembly 90 in the opening 80 allowing sliding movement of the pin 78 in the direction of arrow 92 towards the first surface 86 but preventing such movement in the opposite direction. When the plate 50 is moved by hydraulic operation of a piston 68, the plate 50 acts to squeeze together a number (e.g. three) of rotary discs 16, 18, 20 and a number (e.g. two) of rotatably fixed discs 32, 34; both sets of discs are axially slidable, the discs 16, 18, 20 on a splined shaft 12 to be braked and the discs 32, 34 on torque tubes 28 by means of flanges 62. The discs 16, 18, 20 are formed with the friction pads 44, 46, 48, and there is a running clearance 75 between these pads and the opposing surfaces 64, 40, 42, 66 on the actuator plate 50, the discs 32, 34 and the right end 24 of the housing 22 respectively. As shown two adjuster means 76 are provided, one for each flange 62 and two springs 56 for each flange 62 act to bias the plate 50 towards its retracted position. Each washer assembly 90 of the adjuster means 76 comprises one or more (e.g. two) annular members 94, 96 held in position around pin 78 by a spring washer 99 and a snap ring 101, and with the interposition of a spacer washer 98, and each annular member 94, 96 has inner circumferentially spaced resilent teeth 102, 104 which extend at an angle to engage the surface of the pin 78 and cut thereinto to allow movement in the direction of arrow 92 but prevent movement in the opposite direction. As the brake assembly 10 is energized each pin 78 will move a distance L whence it will come into contact with the surface 60: if wear of friction pads 44, 46, 48 has taken place the pin 78 will be moved in the direction of arrow 92 a distance #L to adjust the retracted position of the actuator plate 50.

Title: Metal salts of 2-carboxy-3-metallo-propenes
IPC: C07C57/48
Filed: 1959-11-30
Abstract: 893,268. Metal salts of 2-carboxy-3-metallopropenes. ETHYL CORPORATION. Nov. 30, 1959 [Dec. 2, 1958], No. 40568/59. Class 2 (3). The invention comprises a metal salt of 2- carboxy-3-metallo-propene. They may be of formula (when both the metal of the salt and the metallo-substituent are monovalent) where each R represents hydrogen or hydrocarbon groups which can be the same or different, R<SP>1</SP> is an alkylene group and M and M<SP>l</SP> are metals which may be the same or different. It is preferred that M and M<SP>1</SP> are alkali or alkaline earth metals. They may be prepared by reacting a metal salt of a 2-carboxy-propene with a metallating agent such as a metal amide, hdyride or in some cases the metal itself and compounds of formula RxM. Lower alkyl derivatives of metal amides may also be used. Compounds specified include sodium, potassium, lithium, calcium and magnesium amides, potassium, aluminium, magnesium, cacsium, beryllium, rubidium, copper, titanium and zirconium hydrides, amyl sodium, disodiooctadiene, dimethyl and diethyl zinc. The reaction may be carried out at a temperature between 160‹C. and 300‹C. The reactants should be of particle size below about 50 microns. An inert atmosphere such as argon, nitrogen or krypton is employed: in some circumstances it is preferred to carry out the reaction under an inert liquid blanket such as a high boiling hydrocarbon oil. Sub-atmospheric pressure may be used to ensure rapid removal of volatile by-products. Many metal salts according to the invention are specified. The compounds of the invention are highly reactive. Carbonation with solid carbon dioxide followed by hydrolysis yields dicarboxylic acid (e.g. the sodium salt of 2-carboxy-3-sodiopropene yields itaconic acid). Alkylation yields longer chain acid salts, and using excess of an organo halide the compounds yield esters of long chain acids. Reaction with compounds of formula RX 2  where X is a functional group reactive with the 3-metallo substituent yields polyester derivatives. Sulphur gives rise to the sodium mercaptide, and epoxidation gives rise to the appropriate metallic hydroxy alkanates. Transmetallation gives rise to organo metallic compounds, e.g. the sodium salt of 2-carboxy-3- sodio propene reacts with a trialkyl tin halide to give the sodium salt of 2-carboxy-3-(trialkyl tin)- propene.

The conditions are so adjusted that the maximum temperature attained by the surface after quenching is 600‹ to 730‹C. That maximum temperature may be selected to produce a desired value of elastic limit in the steel according to a predetermined relationship. Preferably the surface temperature of the quenched material is measured at the entry to a still air cooling stage, and conditions adjusted accordingly.
