IPC: F16C33/80
Filed: 1935-06-07
Abstract: 448,149. Bearings. TENNANT, W. J., 112, Hatton Garden, London.-(Aktiebolaget Svenska Kullagerfabriken; 17, Artillerigatan, Gothenburg, Sweden) June 7, 1935, No. 16661. [Class 12 (i)] The periphery of a dust cover plate 5 is wedged between the relatively inclined sides 7, 8 of an annular groove in a bearing element 1 whereby the plate does not contact with the bottom of the groove and distortion of the outer surface of the element during assembling is avoided. The plate is initially of conical form and is provided at its periphery with spaced projections 6 which are wedged between the groove walls when the plate is flattened by axial pressure In a plane cylindrical bearing Fig. 7, the inner and outer bearings carry plates 25, 33. Grease in the chamber between the plates 33 is forced by centrifugal action through holes 36 to lubricate the bearing and is discharged into chambers bounded by the end plates 25 where it builds up a pressure and assists in forcing the grease in the inner chamber outwardly.

Title: A process for the production of silver-containing layers on aluminium and its alloys
IPC: C23C18/44
Filed: 1950-07-10
Abstract: In a process for producing silver-containing layers on aluminium or its alloys, a firmly adhering oxide layer is produced on the metal, a dyestuff which reduces silver compounds to metallic silver is deposited in the pores of the oxide layer, and finally silver is precipitated in the pores by treatment with a solution of a silver salt.  The oxide layer may be formed chemically or electrolytically. The dyestuff has preferably mordant properties and the following are stated to be suitable: derivatives of anthraquinone, flavone, xanthone, pyronin or oxazine or derivatives of benzene or naphthalene which have hydroxy or amino groups in the ortho or para positions. The silver solution may be ammoniacal silver nitrate.  The silver may be converted to a halogen salt under darkroom conditions and used for printing photographic negatives.  A resist may be painted on the oxide layer and the clear spaces impregnated with dyestuff and then silver or the dyestuff-impregnated layer may be painted with resist before treatment with the silver solution to produce a pattern.  The metallic silver layer may be coloured red-dish to purple-brown by treatment with solutions of copper sulphate, potassium citrate, and potassium ferricyanide, sepia with solutions of uranium nitrate and potassium ferricyanide, or blue with solutions of potassium ferricyanide and iron citrate.  The silver may be replaced by gold or platinum by treatment with solutions of salts of these metals.  The silver may be built up with silver, gold, copper, nickel or chromium. As a final operation the pores in the aluminium oxide layer may be sealed by treatment with warm solutions of nickel or cobalt salts, or boiling water, or steam.

Title: Diagnostic composition
IPC: G01N33/68
Filed: 1956-06-04
Abstract: A diagnostic composition for detecting albumen in body fluids, e.g. urine, consists of an albumen precipitant, e.g. sulpho-salicylic acid, and, an indicator which changes colour at pH 3.6 (at which albumen is completely precipitated), e.g. brom-cresol green. Preferably, a tablet is used containing sulphosalicylic acid, brom-cresol green, boric acid (as die lubricant) and an effervescent couple, e.g. sodium bicarbonate and citric acid.  One 55 mg. tablet, added to 4 ml. of urine is normally sufficient to give a yellow colour.  Presence of albumen is indicated by cloudiness.

Abstract: 1460085 Camera shutters SEIKO KOKI KK 19 April 1974 [19 April 1973] 17297/74 Heading G2A A shutter for an SLR camera has a blade ring 10 which in its initial position holds blades 2 open for focusing, on rotating in a first direction closes the blades and then operates a shutter release which opens and closes the blades to effect an exposure while ring 10 is held stationary, and then rotates in the opposite direction back to the intial position to re-open the blades; and a shutter cocking device which first rotates ring 10 in said opposite direction and then rotates it in the first direction back to the initial position. As shown, ring 10 is coupled to a concentric drive ring 20 operated by rods 23, 24. On depressing a release 32, rod 23 moves left to rotate rings 20, 10 anti-clockwise whereby a lever 5 moves out of engagement with a surface 10c on ring 10 and into engagement with a surface 10e to close the blades Fig. 3. Further anti-clockwise rotation causes a projection 10d on ring 10 to operate a member 7 to stop down the diaphragm (not shown) to a pre-selected value and a projection 10b strikes a release 4 which operates the blades 2 to effect an exposure and moves a lever 6 Fig. 3 into a position in which it is engaged by a stop lever 21 Fig. 8 when the latter is engaged by a pin 20c on ring 20. This stops movement of rings 10 and 20 during exposure When the blades close at the end of exposure, lever 6 is shifted to allow rings 10 and 20 to continue to rotate anti-clockwise until the end 23e of rod 23 releases a catch 31 to allow the rod 24 to move rightwards. This moves rings 10, 20 clockwise whereby lever 5 re-engages surface 10c to re-open the blades. To cock the shutter, linkage 27, 28, 29, 30 operates rods 23, 24 so that rings 10, 20 firstly move clockwise whereby the projection 10b operates a cocking lever 3 and then move anticlockwise back to the initial position.
