Title: Improvements in or relating to autographic registers and like strip-feeding machines
IPC: B41L5/06
Filed: 1938-11-19
Abstract: 521,463. Folding paper. JOHNSTON, C: L. Nov. 19, 1938, No. 33705. Convention date, Feb. 10. [Class 100 (i)] [Also in Group XIX] Relates to strip-feeding machines in which a strip or set of superposed strips which have been previously reversely folded or creased for folding into zig-zag form is fed past a station where it is written or typed upon and then refolded or folded into zig-zag pack form, and consists in using strips with longitudinally spaced holes which are fed by a pin-type feed, stripping means being provided to disengage the material from the pins at different positions in the path of the feed in timed relationship therewith such that alternate folds or creases are directed towards opposite ends of the pack. The inyention is described as applied to an autographic recorder of the kind in which folded voucher and record strips 4, Fig. 5, are drawn over a platen 6 from a supply compartment 9 by pin wheels 10, the voucher strip or strips being issued through a slot 17 in the casing and the record strip being refolded in a storage compartment 18. To assist this refolding cam discs 20 are mounted co-axially with and adjacent to the pin-wheels to control the position at which the strip will leave the periphery of the pin-wheels. As shown in Fig. 5, the cam discs have been rocked counter clockwise to enable the strip to be directed towards the rear of the machine. In the next succeeding operation, the cam discs will be rocked clockwise to the position shown in Fig. 6, and the strip will be directed towards, the rear of the machine. The cam discs are connected for operation by a link 25 to a crank 21 driven from the usual operating handle through a two to one reduction gearing. In a modification, the crank engages directly within a cam slot in one of the cam discs. -

IPC: F15B9/10
Filed: 1959-10-05
Abstract: 938,851. Fluid-pressure servomotor control systems. V. BALASS. Oct. 5, 1959 [Oct. 4, 1958], No. 33744/59. Class 135. In a fluid-pressure operated actuator movement of sleeve 11 to the left by the action at 20 of, e.g. a steering-wheel, seats the sleeve end 25 on the piston 7 and unseats closure member 15 carried by the other sleeve end from a disc 17 carried by the piston-rod 10 and slidable in member 15, the rod 10 being connected to, e.g., steerable wheels. Hydraulic pressure is then exhausted from the left of the piston via piston passage 29, passage 27 between the sleeve and piston-rod and port 21 in member 15, and pressure supplied via cylinder port 5 and constantly acting on the small piston side moves the piston to the left, the sleeve end 25 following up the piston until the limit is reached when member 15 abuts the cylinder end, valve 25 opens and valve 23 closes. Rightward movement of the sleeve closes valve 23 so that the resultant of the pressures acting on both sides of the piston moves it to the right with follow-up of the sleeve. The force exerted by the piston is dependent on the force with which a sleeve end is pressed on its seat so that " feel " is transmitted to the steering wheel, such feel being increased by the bevelled ends 24, 25 of the sleeve. The sleeve is substantially pressure balanced.

Abstract: 848.908. Centrifugal drying machines. SIMPLEX ELECTRIC CO. Ltd. Nov. 26, 1956 [Nov. 26, 1955], No. 33947/55. Class 34(2) In a domestic drying machine the clothes are dried by centrifugal extraction in a perforate drum and are simultaneously subjected to a current of heated air. The machine comprises a perforate drum 10 driven through a pulley 15 by motor 21 and is provided with braking means as described in Specification 848,909 to prevent rotation of the drum when the lid 27 is open. The rotation of the drum creates an air current in the casing, due to the action of centrifuging forces, part of the stream passing through the clothes as indicated by arrows 49 and part moving upwards along the surface 47 as indicated by arrows 48. The two streams combine along path 50 and from an upward flow 44 which passes over an electric heater 53 before returning to the drum through aperture 32. The water extracted from the clothes is collected by drain plate 37 and is discharged through the duct 41 having a trap 54. Any air which escapes through the duct 41 is replaced by fresh air drawn in along path 52 through an aperture in the plate 37, but the trap 54, or flap valve, ensures that air is only lost slowly and the air in the casing is retained sufficiently long to ensure that it is adequately heated. The machine may be mounted for transit as described in Specifications 845,668 and 845,868.
