Title: Length measuring device the measuring axis of which is vertical
IPC: G01B5/00
Filed: 1960-08-08
Abstract: 949,189. Gauges. CARL ZEISS-STIFTUNG [trading as C. ZEISS [firm of]]. Aug. 8,1960 [Aug. 17,1959], No. 27375/60. Heading G1M. [Also in Division F2] In a measuring device in which a workpiece 3, Fig. 1, measured by a vertically movable spindle 3 having a scale 12 adapted to be read by a microscope 13, the spindle 9 is balanced by a weight 8 connected thereto by a rope 7 passing over pulleys 5, 6. The spindle 9 is raised to accommodate the workpiece by pulling on a rope 15 connected to a disc 14 on the pulley 6 and engages the workpiece by gravity on release of the rope 15, whereupon the balance weight will continue to rise further and then descend again. In order to damp this downward movement the weight 8 is constructed as a piston and cylinder, Fig. 2, the piston 23, 24 being coupled to the rope 7 and the cylinder body 20 being coupled to the piston by a spring 26. The cylinder body 20 can thus move relatively to the piston under air damping controlled by a needle valve 34. The downward movement of the spindle 9 may also be controlled by damping means or the downward movement may be effected by a motor in which case a slipping drive may be provided.

Title: Tanning with bivalent iron salts
IPC: C14C3/04
Filed: 1957-08-30
Abstract: 822,997. Iron tanning agent precursors. GLOZIC, B. Aug. 30, 1957 [Aug. 30, 1956], No. 27377/57. Class 76. A tanning agent precursor, which may be in the form of a finely comminuted solid or an aqueous solution, comprises essentially a non- basic or weakly basic trivalent iron salt, such as ferric sulphate or a mixture of such salts, in intimate association with a bichromate, such as sodium bichromate. The iron salts may be partly replaced by trivalent chromium salts or aluminium salts. Neutral salts such as sodium sulphate may be added. Addition of a reducing agent such as sodium thiosulphate or sodium bisulphite is necessary to effect tanning. This reduction may be partially or completely effected before contacting the skin with the tanning agent precursor or may be effected after this contact.

Abstract: 391,032. Fusible cut-outs. FRIDMAN, D., 89, Obere Donaustrasse, Vienna. Oct. 3, 1932, No. 27411. Convention date, Oct. 5, 1931. [Class 38 (i).] A fuse cartridge 23 is positively held out of engagement with the live contacts 17, 18 until a cover 5 is closed. The cartridge rests upon a bush 6 carried in a shell 8 supported on a spring 11. The cover 5 carries a contact 15 that abuts on the upper cap of the cartridge and connects it by means of a tongue 16 engaging a clip fasten. ing 20 attached to the contact 18. The closing of the cover 5 withdraws a supporting projection 14 from beneath a shoulder 24 and compresses the spring 11 pushing the fuse down on the contact 17. An inspection opening may be provided in the cover 5 and upper contacts. The cartridge holder and cover may constitute a plug fuse. The bush 6 forms a gauge ring to prevent insertion of a fuse of too high a rating.

Abstract: 1,132,219. Al based alloy; anodizing. ALUMINUM CO. OF AMERICA. June 21, 1966 [July 19, 1965], No.27785/66. Headings C7A and C7B. An aluminium base alloy which can be anodically oxidized to give an oxide layer having a colour ranging from 1) a yellow level up to 35% yellowness to 2) a black of 4% maximum in both apparent reflectance and yellowness, comprises Mg 0À4 - 1À0% Si 0À25 - 0À6% to give 0À6-1À6% Mg 2  Si Cr 0À1 - 0À35% Cu 0À35 - less than 1% the balance, apart from impurities and incidental elements such as: - Fe up to 0À4% Mn up to 0À1% Zn up to 0À1% Ti up to 0À1% being aluminium. To obtain the desired coloured coating the alloy is hot worked (e.g. by rolling, extruding, pressing or forging at 700‹-900‹F. after an optional pre-heating at 950‹ - 1050‹ F.), quenched, optionally cold worked and precipitation hardened at 300-475 ‹F, followed if desired by a cold-working step prior to the anodic oxidation step. The anodic oxidation is performed in an acid electrolyte (e. g. one or more of H 2 SO 4 , oxalic or sulphophthalic acids) and in examples a 15% H 2 SO 4  solution was used at 65‹ - 75‹ F. and 12 amps/sq. ft. or at 25‹ - 28‹ F. and 36 amps/ sq. ft. to give different colour coatings. The coating may be sealed, e.g. by immersion in water at 208 to 212‹F. or in known hot aqueous solutions. The colours of the anodically produced films can be modified by impregnating them with known substances.

Abstract: 646,564. Electric filters. COMPAGNIE GENERALE D'ELECTRICITE. Sept. 17, 1946, Nos. 27870 and 27871. Convention dates, Aug. 23, 1945 and April 12, 1946. Drawings to Specification. [Class 40 (viii)] A lattice unit for an impedance network comprises a pair of series impedances and a pair of shut impedances one pair being equal and the other pair being unequal but chosen so that the filter unit is electrically equivalent to the standard unit having two pairs of equal impedances. A mathematical demonstration is given to show that in the case when the impedances are each made up of a number of resonant elements, it is always possible to choose values for the unequal impedances that will result in a fewer number of resonant elements being required in the proposed unit than in the equivalent standard unit. The reasoning is applied to high pass, low pass, and band-pass filters, and also to equalizing networks for use with cables. Specification 632,569 is referred to.

[Also in Division F2] Cigarettes &c. are fed by an endless conveyer 4 to a collecting point, whence they are lifted in a long row 146 by a suction head 14 comprising individual holders 16. Every eighth holder 16 has a plunger 72 operated by an arm 74 when a shaft 78 is rotated, to remove each eighth cigarette to form a series of short rows (148) of cigarettes 2. Plungers 70 then slide these cigarettes 2 off the suction heads 14 into rectangular pockets 164 of a container (152). The removed cigarettes roll down a strip 60, inclined by the raising of the suction head 14, to start a new long row 146. The container (152) is fed down a step between cycles. The cycle is repeated to lay further short rows 148 upon those already in the pockets 164. To form a row of six cigarettes between two rows of seven, further plungers 73 operated by a shaft 80 act with the plungers 72, the raised suction head 14 being displaced horizontally by half a cigarette diameter. The control circuit, Fig. 25 (not shown), using compressed air and electric signals to control the raising of the suction head 14 and operation of plungers 72, 73 is described, as are the arrangement and operation of the star wheels (38, 40) and cam (42) mounted on the arms 28, 30 carrying the suction head 14, Figs. 16 to 21 (not shown).
