Abstract: 635,764. Clutches. COLLINS RADIO CO. Sept. 17, 1946, No. 27897. Convention date, Jan. 5. [Class 80 (ii)] [Also in Group XXXVIII] A shaft positioning arrangement has a plurality of stop combinations, one for each of the shaft positions, each combination comprising a cam which controls a pawl to engage a stop-ring rotatable with the shaft, the cams being driven by a single-direction motor, until a particular pawl is selected, the shaft being further rotated until stopped by the engagement of the selected pawl with the corresponding stop ring. The invention is described with reference to the tuning of a wireless receiver. The tuning condenser (not shown) is rotated by shaft 23, Fig. 4, which carries a drum 25 having stop rings 25A ... 25K ; these stop rings are angularly adjustable by loosening wing nut 29a, and each has a notch as shown in Fig. 1 ; co-operating with each notch are pawls 35A ... 35K adapted to engage the notch and stop rotation of shaft 23 which is driven through a friction clutch : each pawl e.g. 35b, Fig. 1, is extended to form a further pawl 35a engaging one of appropriately angularly and axially located notches on a cam drum 45, so that when e.g. pawl 35a enters the corresponding notch in drum 45, pawl 35b rides over its corresponding stop ring and engages the notch 25a therein to stop the shaft 23. To select a station, arm 84a, Fig. 13, is moved to the appropriate contact e.g. 84d to complete the circuit of the driving motor 47 over contacts 93c, 93d and energize solenoid 72 ; the solenoid couples drum 45 to a driving shaft (described below), and the motor drives gapped commutator 80 and drum 45 until the gap opens the circuit at 80d, when solenoid 72 de-energizes to uncouple drum 45 in the selected position ; the motor circuit is not opened as contacts 93e, 93b have been made by a limit switch described below. The motor continues to rotate, driving shaft 23 until the pawl 35b, Fig. 1, riding on its corresponding stop ring 25 engages slot 25a holding shaft 23 against further rotation ; the motor continues to run until contacts 93e, 93b are opened by the limit switch. Coupling drum 45.

Abstract: 862,110. Bottling. ROCKCOTE PAINT CO. March 13, 1959 [Sept. 2, 1958], No. 28118/58. Class 125(2). [Also in Group XXVIII] A liquid dispensing machine particularly for paint comprises a number of reservoirs 11 mounted on a carrier 10 which is rotatable about an axis 68, and a separate dispensing pump 12 associated with each reservoir so that by turning the carrier 10 the pump may be brought into alignment with a driving mechanism 13 which is adapted to reciprocate the pump operating rod 58. When the rod 58 is reciprocated the pump cylinder 48 is supported at the side furthest from the reservoir by a U-shaped member 125. The carrier 10 is rotated manually by a crank, gear and chain drive to the sprocket 167 and is supported at its periphery by wheels 34 disposed on legs 29, horizontal wheels 37 operating to centre the carrier. The cylinder 48 of each pump is screwed to a rigid block 61 which is fixed in a projecting part at the bottom of the reservoir and is perforated at 68 to allow liquid to flow into the pump. The pump piston 53 has a valve 56 which opens as the piston is raised and the nozzle 49 of the cylinder has a check valve 52. The piston is reciprocated by a jaw 81 which is movable by the screw and gear mechanism 86, 92 and 93 manually operated by the crank 96 with handle 97. The distance the jaw moves is varied by rotation of a cam plate 105 against which the jaw abuts in its lower position. The block 91 in which the crank is journalled is resiliently held in place by spring 100 arranged to be overcome when a certain pressure (i.e. when the jaw abuts the cam plate) is applied to the crank. The U-shaped member 125 supports the outside of the pump in operation and is mounted at the upper end of a pivoted yoke 127 which straddles the box 23 at the dispensing station and is movable into and out of engagement with the pump by a latch lever 136 with handle 142. An interlocking rod extending between the member 125 and the jaw 81 is arranged to prevent movement of the jaw when member 125 is not in operative position and also to prevent this member from being disengaged from its operative position when the jaw is not in its uppermost position. The reservoirs 11 are detachably secured to the carrier 10 and have stirrers 178 and 180 rotated by belt 182a and have a filler opening with plug 172 having a vent hole 173 and a container for a pad 174a impregnated with a thinning agent and an anti-oxidant. Rollers for wiping the tips of the nozzles after use are incorporated.

Title: Improvements in and relating to the manufacture of composite titanium pigments
IPC: C09C1/00
Filed: 1926-11-09
Abstract: 281,459. Wade, H., (Titanium Pigment Co., Inc.). Nov. 9, 1926. Pigments.-Composite titanium pigments are produced by suspending preformed acicularly crystalline calcium sulphate in a titanium solution and precipitating the titanium compounds on to the sulphate. The process may be effected by heating a titanic sulphate solution containing the suspended sulphate, which may be in the form of a concentrated pulp. The acicularly crystalline calcium sulphate may be prepared (a) by precipitating it in alkaline medium by adding aqueous sulphuric acid to an excess of alkaline calcium compound such as lime, (b) by precipitating it in acid medium by adding a calcium compound such as lime or calcium carbonate to aqueous sulphuric acid, for example, the solution obtained by hydrolytically precipitating titanium compounds from a titanium sulphate solution, (c) by heating natural gypsum or a bye-product sulphate to destroy the original structure, milling the product and hydrating it with water. When prepared by precipitation, conditions, such as continual agitation, should be promotive of a finely divided precipitate. The composite precipitate may be calcined with an agent inhibitive to colour change during calcination, such as phosphoric acid or calcium phosphate.
