Filed: 1952-08-05
Abstract: 717,380. Multiplex radio signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Aug. 5, 1952 [Aug. 3, 1951], No. 19644/52. Drawings to Specification. Class 40 (5) Relates to superheterodyne television receiver employing the inter-carrier method of operation (i.e. the sound and vision carriers are beat to produce a sound intermediate frequency of constant frequency) in which sound is received when vision signals are not being transmitted by beating with the sound carrier auxiliary oscillations generated so that the same constant intermediate frequency results. According to the invention the frequency of the local 'oscillator of the receiver is altered so-that the sound carrier occupies a position in the receiver I.F. pass-band corresponding to increased or maximum amplification, e.g. that normally of the vision carrier and an equal change is made to what would otherwise have been the frequency of the source of auxiliary oscillations. The auxiliary oscillations may be applied to the detector following the receiver I.F. channel, or to an I.F stage. If the I.F. stages are stagger-tuned those amplifying that side of the IF. pass-band including the frequency of the auxiliary oscillations are located after the point where the auxiliary oscillations are fed in.

Title: Chromatographic gas analysis sample control system
IPC: G01N30/06
Filed: 1958-06-24
Abstract: <PICT:0833864/III/1> An apparatus for repeatedly producing and supplying gas samples of fixed volume and constant mass to a standard chromatographic column, consists of a tube of fixed volume to which the gas is fed and is then connected to one of a pair of contractible and expansible housings of the bellows type, working in opposition against a common flexible diaphragm, the other housing containing a reference gas sealed therein, whereby any variations in temperature during the preparation of the series of samples resulting in a variation in the density of the gas samples, is exactly compensated by an increase/decrease in pressure on the sample to obtain the same mass of the gas.  In one form of apparatus the gas to be sampled enters a tube 20, to the standard fixed volume tube 12, and after control by the double bellows assembly 10, is swept by carrier gas admitted through a tube 19 into the chromatographic column 15 at the base of which is a detector 16 producing a signal 17.  The admission, isolation, control, and injection of the sample gas into the carrier gas is operated automatically by switch valves 1 . . . 5, controlled by solenoid-operated pneumatic valves in the assembly 13 in accordance with a preselected timing programme.  The bellows 27 is fed with a metered quantity of a reference gas, preferably the same as the gas under test to avoid variations in physical characteristics.  The upper bellows 32 is connected by a pipe 25 to the gas sample to be controlled, and is provided at the top with a bleed valve 38 pressing against a seating 39 and also a diaphragm 37. Excess gas leaves through a pipe 41, and creates a backpressure in tube 42 connected to a jet 35 through which a gas flows from an inlet 43, until the pressures are in balance with that of the reference bellows when diaphragm 34 closes the end of jet 35.  A spring-loaded screw 36 provides adjustment of the diaphragm to required conditions. The bellows assembly 10 and fixed volume tube 12 are housed in a chamber to maintain a uniform temperature.  In modifications (not shown), two bellow chambers are replaced by a fixed chamber separated into upper and lower chambers by a sensitive flexible diaphragm.

Abstract: 749,970. Dough-sheeting machines. SEEWER, G. A July 12, 1954 [July 10, 1953], No. 20284/54. Class 87(2) To prevent wrinkling' of the dough emerging from the rolls of a dough-sheeting machine of the type comprising a pair of superposed rolls 2, 3 (Fig. 1) adapted to be rotated in opposite directions and having conveyers 13, 14 on the ingress and egress sides, the conveyer on the ingress side, which may be either side (as the drive is reversible) is adapted by a clutch mechanism to move slower than that on the egress side. As shown in Figs. 1, 2 the driving sprocket 10 for a drum 12, over which the conveyer 14 passes, is freely rotatable on rollers 15 on a shaft 16 connected to shaft 20 of the drum 12, and has an annular cylindrical flange 10<1> enclosing a clutch 16<1> connected to the shaft 16 which it rotates through frictional engagement with rollers 36, when rotating in the direction shown by the full line arrow of Fig. 3. When the direction of rotation is reversed as shown by the dotted line arrow of Fig. 3 the flange 10' slips over the rollers 36 and the rotation is transmitted in this case by a friction disc 10<11>on the flange 10 which engages frictionally with a plate 16<11> pressed on to the disc 10<11> by an adjustable spring 32, the plate 16<11> rotating shaft 16 through pins 26 axially movable in slot 27 in shaft 16. The clutches are so mounted that the one on the ingress side is slipping when the other is engaged and if the common drive from endless chain 8 (Fig. 1) be reversed their respective roles are also reversed. A modification of the slipping part of the above clutch mechanism is shown in Fig. 3 comprising springs 34 in holes 33 which push rollers 36 into frictional engagement with flange 10<1> which will thus transmit its motion with a fixed slip ratio to the shaft 16 when rotating in the direction of the dotted line arrow.
