Title: Improvements in or relating to means for converting reciprocating into rotary motion
IPC: F16H21/38
Filed: 1937-03-08
Abstract: 485,038. Converting reciprocating intorotary motion; pistons; crossheads. SARKAR, C. S. March 8, 1937, No. 6819. [Class 80 (iii)] [Also in Group XXVI] Pistons and crossheads of engines and pumps are made in two parts, each with projections which come into contact and assist in overcoming deadcentres. The additional turning-effort exerted by the projection 22, Fig. 1, on the projection 10 of the connecting rod is resisted by springs 29 or by fluid pressure. Fig. 15 shows the application to the crosshead of a double-acting engine. Projections 22a, 22b, on the frame 18a carried by the piston-rod, engage projections 10a, 10b on the connecting rod which is attached to the main crosshead 6a. The engaging parts may be off-set axially with regard to the piston, one projection being then carried by a lever connected at its two ends to the two parts of the piston.

Title: Improvements in receiving stations for transmission systems with suppressed carrier wave
IPC: H04B7/12
Filed: 1950-03-20
Abstract: 678,079. Radio receiving systems. COMPAGNIE INDUSTRIELLE DES TELEPHONES. March 20, 1950 [March 28, 1949], No. 6828/50. Class 40 (v). In a suppressed carrier multi-channel telegraph system employing discrete voice frequency sub-carriers corresponding to each channel amplitude modulated on a main carrier with suppression of the carrier and comprising at a receiver a demodulator 3 fed by restored carrier frequency from an auxiliary modulator 10 to which both the received wave and a demodulated output of the receiver are applied, the carrier is derived' from a filter 14 with passband centred about the carrier frequency and of band-width less than twice the frequency difference between the closest frequencies of any of two adjacent channels. The carrier frequency is therefore derived exactly irrespective of amplitude and phase distortion in transmission. In a modification, Fig. 2 (not shown), the derived carrier is fed to a separate demodulator to which only a single side-band of the received wave is passed. In a further modification, both side-bands are separately demodulated. The latter permits frequency diversity reception. Specification 449,999 is referred to.

Abstract: 624,586. Bread-slicing machines. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. March 17, 1947, No. 7260. [Class 5(i)] Relates to breadslicing machines of the type wherein the bread is sliced by thin endless bands guided by knifeguides which are laterally adjustable to vary the slice thickness. According to the invention, the knife-guides 17 are arranged for free lateral movement on a common shaft 28 and alternate with a series of abutment members 27 each of which is in threaded engagement with a guide so that the abutment members, which are simultaneously adjustable by the rotation of the shaft 28 determine the lateral spacing of the knife-guides. The guides include finger-like portions having slots 26 through which the blades run and carry slotted tail-pieces 34 which engage a stationary bar 36 to maintain the guides in parallel relation. The guides (see Fig. 4)include cylindrical, internally-threaded portions 24 concentric with the shaft 28 and having an inwardly-projecting flange 32 which engages a corresponding flange 33 on the next abutment member. Each abutment member 27 comprises a collar keyed on the shaft and provided with a flange 31 at one end and a threaded flange at the other which engages with the internal thread on the part 24. The central knife-guide is bolted to the bar 36. The end guides are integral with threaded extensions 37 which provide bearings for the shaft 28. These extensions are threaded within bushes 38 rotatable on the main frame by hand wheels 51. The shaft 28 is rotatable by a hand wheel 42 provided with a spring-loaded locking device.. The shaft is formed with a relatively coarse thread 54 on which is mounted a nut 52 carrying a pointer 53 moving over a scale 57 to indicate the knife-spacing. This spacing is altered by first rotating the hand wheels 51 to move the outer guides inwardly and then rotating the shaft 28 to screw the abutment members into or out of the corresponding guides. The hand-wheels 51 are then rotated until all the flanges 31 and 32 abut.

The plastic polymer in low relief preferably is also a polyurethane elastomer and is deposited as a viscous pigmentcontaining solution thereof, by mezzo printing. It is preferred to deposit a higher relief visible pattern of plastic polymer over the discontinuous pattern or open pattern to produce a surface having higher relief polymer masses with the low relief pattern between the masses. This higher relief pattern is suitably deposited as a viscous pigment-containing solution thereof, by intaglio printing. After depositing the relief pattern the microporous sheet material may be heat-treated to cause a shrinkage of at least 5% in area. Fig. 1 (not shown ) is an enlarged photomicrograph looking down at the upper surface of a microporous sheet showing a relief pattern, the surface carrying spaced masses 32 of elastomeric polyurethane and an open pattern of thin irregular-shaped lines, or low ridges, 33 of thermoplastic polyurethane, in the spaces between masses 32.
