Title: Improvements in or relating to weighing apparatus
IPC: G01G1/26
Filed: 1924-07-19
Abstract: 219,684. Schember & S÷hne Br³ckenwagen-und Maschinenfabrik Akt.- Ges., C., and Peuker, F. July 25, 1923, [Convention date]. Loose-weight apparatus.-In a weighing-apparatus wherein a set of weights is enclosed within a casing and the weights transferred to and from the weights pan by external operating means, the weights are transferred successively from the weights pan by means of teeth arranged upon a lever, slide or the like, the teeth being so shaped that they first move the weights and then retain them in an inoperative position. Several sets of weights may be used corresponding to the numbers of the decimal or other system employed. As shown in Fig. 1, a set of cylindrical weights 3 having trunnions 15 rests on an incline on the weights pan 1 (shown in its highest position), and the trunnions project into slots 5 in the frame 6. Pivoted on the frame is a hand-operated comblike device 7 provided with teeth 9 - - 12. When the comb 7 is rotated the outermost tooth engages the trunnions of the corresponding weight and pushes the trunnions into a recess at the top of the slot 5 thereby raising the weight slightly from the weights pan. The face 14 of the tooth retains the weight in this position. Continued rotation of the comb similarly transfers the remaining weights in succession. Instead of pivoting, the comb may have a rectilinear movement. Taring devices.-The Specification as open to inspection under Sect. 91 (3) (a) comprises also the taring device shown in Fig. 8 (Cancelled). Taring material is run from a funnel 18 into a funnel 19 carried by the weights pan excess material being run off into a drawer 22. The funnels are provided with hand-operated sluices 20, 21. This subject-matter does not appear in the Specification as accepted.

Abstract: 665,835. Disinfecting air. GREEN, A. June 23, 1949 [June 29, 1948], No. 17404/48. Class 81 (i). An air-conditioning appliance (operating by ozonising the atmosphere) comprises an electric arc discharge device and a switch with which is associated a time-lag device adapted to switch on and off the discharge device for a predetermined time. As shown, the device comprises an electric arc discharge device 14 of the kind described in Specification 665,853, [Croup XL (a)], a transformer 16, a fuze box 15 and a switch associated with a dashpot 24.

Abstract: 531,313. Hydraulic transmission of power. FITZJOHN, A. P. June 23, 1939, No. 17453/40. Divided out of 531,257. [Class 69 (ii)] A tool-slide or the like is yieldingly retarded during the forward stroke by means of a piston actuated by the tool-slide and mounted in a cylinder which communicates through a valve with the pressure source, the valve being arranged to permit restricted and unrestricted flow during forward and return movement of the piston respectively. In the construction shown in the Figure, the tool-slide 17 is provided with an adjustable bolt 48 for actuating a piston 37 mounted in a cylinder 36 which communicates through a valve 35 with a pressure inlet 43. The valve is mounted in a housing 40 and consists of a disc formed with peripheral ports 47, and a conical needle 38 which enters the conical end of a port 42 in a threaded plug 41. A tool can be inserted in a slot 45 to adjust the plug. When the bolt 48 engages the piston 37, the valve is forced on to its seat 39, liquid flow from the cylinder 36 is restricted, and the speed of the tool-slide is reduced. On return of the tool-slide, the valve opens, and the pressure on the piston accelerates the tool-slide. In a modified form of valve, the plug can slide in the housing and engages an adjusting-screw. The needle 38 may be formed on the plug.

The mixer shown in Fig. 1 comprises an inner component 1 with a helical thread 12 and an outer component 2 with a helical thread 13 of opposite hand, the components being adapted for rotation in opposite directions. The screw groove 15 in the component 1 varies in cross-section with corresponding variation in an opposite sense of the groove 16 in the component 2. The mixer extruder, with extrusion head 32 of Fig. 4, has the outer component 2 in four sections 21...24 driven independently. There are two start threads of opposite hand on the inner and outer components which rotate in opposite directions. In the mixer shown in Fig. 5, material supplied through a funnel 6 is mixed in its passage between components 1, 2 and may be further mixed with material supplied through a funnel 37 and passed between the component 2 and an outer rotatable component 36, the component 2 stopping short to allow the materials to be mixed between components 1 and 36. Fig. 6 shows another extrusion mixer, suitable for injection of plastics, comprising screw components 1, 2 in sections, the outer component sections being separately driven. The inner screw component 1 is rotated and is also given a reciprocating movement through eccentrics 64, 63 and an eccentric driving shaft 66, the reciprocating stroke being adjustable.
