Filed: 1973-04-12
Abstract: 1459101 Rear view mirrors WINGARD Ltd 9 April 1974 [12 April 1973] 17545/73 Heading B7J An exterior rear view mirror comprises a rotatable spindle incorporating an eccentric portion 46 which is threaded at 49 to engage in a nut member 51 associated with a mirror head 41, so that rotation of the spindle rocks the mirror head about a first axis and movement of the nut member 51 along the spindle tilts the mirror head about a second axis perpendicular to the first axis. The nut member 51 has lugs 52 engaging in notches 53 in a block 42 which carries the mirror head 41. Block 42 also includes a ball 43 which is pivotally received in a socket 44 of the base of a U-shaped frame 45, the limbs of frame 45 having slots 48 in which bearing portions 47 of the spindle are rotatably supported.

Title: Improvements in the process of electrolytically separating copper from nickel
IPC: C25C1/12
Filed: 1920-06-29
Abstract: 145,600. Goldberg, P. July 9, 1918, [Convention date]. Copper and nickel, obtaining.-In treating copper nickel alloys in hydrochloric acid or acid chloride solutions, an oxidizing agent such as chlorine is introduced at intervals or continuously, so that the copper deposited at the cathode is equal in amount to that dissolved from the alloy constituting the anode, while the nickel remains in solution. The chloride may be common salt; or the initial electrolyte may be a solution of 135 gm. crystallized cupric chloride per litre of 25 per cent hydrochloric acid. At a low electric pressure, copper and nickel dissolve from the anode as sub-chlorides, no copper being deposited until a large part of the cupric chloride is reduced. No chlorine is added until deposition has brought down the proportion of copper in solution to about 4 per cent. The anode may contain 30 per cent of copper. When the solution is sufficiently rich in nickel, it is treated for the recovery of this metal by known means.

Title: Improvements relating to devices for the administration of muscle relaxants
IPC: A61B5/352
Filed: 1955-06-20
Abstract: 769,876. Administering drugs. WELLCOME FOUNDATION, Ltd. June 20, 1955 [June 18, 1954], No. 17771/55. Class 81(2) The administration of a muscle relaxant is controlled by the response of a muscle to which an electrical stimulus is periodically applied. In the example described a device 22 supplies electrical impulses, at approximately ten-second intervals, to contact bands 20, 21, so placed as to cause contraction of the index finger towards the thumb and thereby cause closing of electrical contacts 18, 19. This energizes a relay 16 which opens an electrically operated valve 15 to allow liquid to flow from a reservoir 10 to an injection needle 11. The valve 15 comprises a solenoid operated pinch cock on a rubber tube. The tube is normally kept closed by spring pressure but energization of the solenoid overcomes this pressure and releases the tube

Filed: 1937-12-20
Abstract: 510,081. Fusing and working quartz. SKAUPY, F., and WEISSENBERG, G. J. Dec. 20, 1937, No. 17859/39. Divided out of and addition to 508,013. [Class 56] Relates to the method of making articles of vitreous sintered quartz (described in the parent Specification), according to which the material is so heated that it does not remain longer than 15 minutes within the region of cristobalite formation, particularly 1470‹-1710‹C. According to the present invention, the material is heated to the temperature range in question for a period which is longer than 15 minutes according to the type of material employed or the nature of the binder used, but not long enough to cause the formation of any substantial proportion of cristobalite. The moulded material may be preheated, immediately before sintering.

Title: Electrostatic copying apparatus

Filed: 1964-04-29
Abstract: 1,066,831. Analyzing mixtures photoelectrically. SAVIN BUSINESS MACHINES CORPORATION. April 29, 1964 [May 8, 1963], No. 17882/64. Heading G1A. [Also in Divisions G2 and G3] In an apparatus which may be an electrophalographic copying machine the proportion of toner to carrier material in reservoir 10 is maintained constant by regulating the supply of fresh toner from hopper 76 using a control system in which the opacity or reflectivity of the developer material in the reservoir is sensed by a photo-conductive cell 34. Light from lamp 18 is directed through window 14 and is reflected by the developer powder on to cell 34, the reflectivity increasing when the proportion of dark toner to light carrier falls. Cell 34 is placed in an arm of a Wheatstone network and balanced against an identical cell 32 which is exposed only to direct light from the lamp. The balance is found for a chosen concentration of toner, using variable resistors 50 and 100. When the toner concentration falls the bridge is unbalanced and the potential of terminal 44 falls whereby the p-n-p transistor 54 whose base 56 is connected to 44 becomes conducting to energize coil 64 and to close relay switch 68. Solenoid 70 is thus energized and lowers hopper plug 82 through lever 90. Toner then enters reservoir 10 and is mechanically mixed with the carrier until the reflectivity falls and the circuit closes the hopper. In the preferred embodiment, a mains supply is used through transformers tappings and is rectified. When the system is used with a liquid developer, a mirror is placed some distance behind window 14 and the variation of light transmitted through the liquid regulates the toner supply. The initial setting of resistors 100 and 50 determines the contrast of the final prints. Examples of powder and liquid developers are given.
