Abstract: 130,496. Lancaster, M. L. Sept. 2,1918. Card, ticket, and like cases.-A bag or wallet for use in the payment of wages is formed with a perforated or transparent portion through which the coins can be seen, and is so arranged that, after the bag has been sealed to prevent withdrawal of the contents, the paper money projects from the end of the bag so that it can be checked. In one arrangement, a paper or other bag is, after insertion of the money, folded transversely, as shown in Fig. 4, and a gummed sealing-strip B is then applied to secure the bag and the paper money in the folded condition. In another arrangement, the bag and the enclosed paper money are folded longitudinally or obliquely, as shown in Figs. 11 and 15, and are then folded transversely, the parts being secured in the folded condition by gum applied to a part B of the bag. In a further modification, the bag has tapered sides, the mouth of the bag being narrower than the paper money, which,. when inserted in the bag bends longitudinally and adapts itself to the tapered shape of the bag. Specification 16243/15 is referred to.

Title: Improvements in or relating to a differential amplifier
IPC: H03F3/45
Filed: 1961-04-21
Abstract: 971,308. Valve and transistor amplifying circuits. REDCOR DEVELOPMENT CORPORATION. April 21, 1961 [April 22, 1960], No. 14557/61. Headings H3T and H3W. In a differential amplifier exhibiting high common mode rejection, the signal comprising wanted balanced components # 8 , #<SP>1</SP> 8  and an unwanted common mode component # CM  is applied to a pair of similar amplifiers 16, 18, Fig. 1. The outputs from the amplifiers 16, 18 are combined in a differencing circuit 30, to give the desired signal which is amplified by an output amplifier 32 and applied to output terminals 10. The outputs from the amplifiers 16, 18 are also combined in an adding circuit 26 to give the unwanted common mode signal, which is amplified in an amplifier 28 and applied as negative feed-back to the amplifiers 16, 18, via a bridge network comprising resistors R 1 , R 2 , R<SP>1</SP> 1 , R<SP>1</SP> 2 . Negative feed-back for the desired balanced signal is also applied back to the amplifiers 16, 18 by returning resistor R<SP>1</SP> 2  to the output of amplifier 32. The various amplifiers are preferably of the chopper stabilized type. The differencing and adding circuits 30, 32, respectively, may comprise transformers (Fig. 2, not shown). In a simplified modification the output of the one amplifier 18, Fig. 3, is applied directly to output amplifier 32 feeding output terminals 10, and the output of the other amplifier 16 to feed-back amplifier 28. Feed-back is, as in the first instance, applied from amplifier 28 to amplifiers 16, 18 over resistor network R 1 , R 2 , R<SP>1</SP> 1 , R<SP>1</SP> 2  and overall feed-back from the output of output amplifier 32 by returning resistor R<SP>1</SP> 2  to the output of this amplifier. A speedier response is obtained by shunting amplifiers 32, 28 with capacitors C 1 , C 2 , respectively, while capacitor C 3  feeds a compensating current to the input of amplifier 32 to compensate for highfrequency common mode signal components present in the output from amplifier 18. Each of the amplifiers 16, 18 may comprise a transistor (Fig. 4, not shown) with the signal input applied to the base and negative feed-back signals to the emitter. The overall gain of the arrangement may be varied by connecting one of a number of resistors, by means of a switch, between the join of resistors R 1 , R 2  and the join of resistors R<SP>1</SP> 1 , R<SP>1</SP> 2 .

Title: Extrusion of thermoplastics materials
IPC: B29C48/92
Filed: 1971-05-14
Abstract: 1370946 Controlling extrudate thickness WAVIN PLASTICS Ltd 15 May 1972 [14 May 1971] 14875/71 Heading B5A [Also in Divisions G3 and H4]  The thickness of thermoplastics material being extruded is monitored or determined absolutely or comparatively from the propagation time of an ultrasonic pulse transmitted through the thickness of the material while the material is at a temperature above its melting point. In the embodiment described the wall thickness of plastics pipe is monitored where the pipe emerges from a sizing sleeve at an extrusion head and before the pipe passes into a cooling water bath. Four transmit/receive probes spaced at 90 degree intervals around the pipe circumference are reciprocated about the pipe axis to scan the pipe circumference, each probe acting in a pulse-echo mode. The echo-time of a pulse reflected by the inner surface of the pipe is measured, or is compared with the echo-time of a reflection from the pipe outer surface, or is compared with the propagation time of a pulse transmitted through the thickness of a reference plastics specimen maintained at a given temperature. The measurement or comparison result is used to regulate the extrusion apparatus to keep the pipe wall thickness uniform and within prescribed limits, e.g. by varying the extrusion rate or the rate of draw-off of the pipe from the extrusion head or the local temperature of or radial position of the extrusion die. Alternatively an alarm may be actuated if the thickness goes outside the limits. A liquid (e.g. the cooling water) or a profiled solid body is used to couple each probe acoustically to the pipe. A through-transmission measurement mode may be used instead of the pulse-echo mode.

Abstract: 1429135 Cameras POLAROID CORP 4 April 1974 [11 April 1973] 15020/74 Heading G2A  A shutter-diaphragm has an electromagnet which is energized during the opening movement in order to slow it. As shown, the shutterdiaphragm is part of a Land type SLR camera and comprises two blades 140, 142 having apertures 144, 146 and connected to a beam 154 which is biased by a spring 168 to close the blades. After viewing and focusing an electromagnet 180 is energized to draw in its plunger 188 against a spring 196, whereby spring 168 can close the blades. The moment the blade apertures 144, 146 move out of over-lapping relation the plunger operates a switch S2 to reduce the current through the electromagnet 180 and save power. When the reflex mirror is properly raised, the electromagnet is switched off and spring 198 pushes out plunger 188 to open the blades against the force of spring 168. As soon as the blade apertures 144, 146 start to overlap the plunger operates switch S2 to energize the electromagnet at the lower current level in order to slow the opening movement. The duration and extent of the opening movement is controlled by a circuit 266 Fig. 7, (not shown) comprising a photovoltaic cell (356) integrating capacitor (352), differential amp (358) and Schmitt trigger (258) which energizes the electromagnet at the higher current level to withdraw plunger 188 and close the blades. Preferably a plug 190 against which the plunger 188 abuts is apertured at 214 to release pneumatic compression and thereby speed blade closure.
