Title: Improvements in or relating to embossing machine for capsules
IPC: A61J3/00
Filed: 1952-11-07
Abstract: 718,242. Embossing machines. SCHERER CORPORATION, R. P. Nov. 7, 1952 [July 12, 1952], No. 28099/52. Class 100 (2). [Also in Group XXX] An embossing machine for gelatine capsules comprises a conveyer for the capsules, an embossing element adjacent the conveyer and pairs of rollers on the conveyer adapted to receive a capsule between them and roll it with contact with the embossing surface. The conveyer, Fig. 1, comprises a chain of links 24 passing round sprockets 20, 22 of which the former is driven. Pairs of rollers 26 having rubber tyres 28 are mounted at spaced intervals along the chain and are adapted to receive capsules 34 from a shoot 32 and, by rolling on a surface 30, to rotate so as to roll the capsules against the embossing surface of a heated die 56, Fig. 3, which embosses a mark thereon. The die surface is formed with a series of ribs or pips to provide a roughened shield, on the surface of the capsule, letters being cut in the die surface to leave unroughened letter forms within the shield. The capsules are released one at a time from the shoot by an escapement mechanism comprising a pair of blades 36 reciprocated in opposite directions by a rocker 40 actuated through a link 48 and lever 46 by a cam 44 mounted on the shaft 16 of sprocket 22. Parallel bars 78, Fig. 2, bear downwardly on the sides of each capsule to urge it into contact with the rollers 26 as they move over the surface 30. Bars 78 are supported on levers 80 pivoted at 82 and crossing over below the pivot for connection to links 84 joined to a spindle 88. The weight of the spindle and links urges the bars 78 together and the links provide for symmetrical movement of the bars to keep the capsules central on the rollers. A second die 56a may be provided to mark the other side of the capsule. Both dies are mounted for vertical adjustment on a supporting bar 60 by screwed rods 62, 62a. The rod 62a is mounted by nuts 64a in a longitudinal slot 66, whereby the position of the second impression may be adjusted. Marked capsules fall off the conveyer onto a delivery shoot 76. The dies are heated by electricity and their temperature is controlled by thermostats.

Title: Improvements in or relating to amplifier circuits having a constant or substantiallyconstant gain
IPC: H03F1/54
Filed: 1946-09-20
Abstract: 625,915. Valve amplifying circuits. PHILIPS LAMPS, Ltd. Sept. 20, 1946, No. 28251. Convention date, March 19, 1943. (Class 40 (v)] [Also in Group XXXIX] An auxiliary tone lying outside the signalfrequency band is utilized for maintaining the gain of an amplifier constant. An audio tone from a source 8 is applied in series with the input of a high-frequency amplifier, the intervalve couplings of which are modified by the inclusion of resistances 11, 19 and condensers 10 to pass the tone frequency. At the output a transformer 12 applies the tone to a rectifier whose output is combined in opposition with that of a further rectifier 14 coupled to the source 8 to give a D.C. potential controlling the gain of the valves 3, 4. The gain of the amplifier may be varied by altering the ratio of the voltages compared by the two rectifiers. In an alternative arrangement (Fig. 2, not shown), the tone is generated by back-coupling the amplifier to obtain self-oscillation, the gain being controlled by means of a rectifier coupled to the feedback circuit. The auxiliary tone may be amplified before rectification, and may alternatively comprise a non-sinusoidal oscillation, for example a relaxation oscillation.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D21/12
Filed: 1927-10-27
Abstract: 305,064. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Oct. 27, 1927. Lasting. - An upper conforming machine having provision for up-wiping is provided with variable detecting means for determining the aspect of a portion of the surface of the last proximate to the position at which upwiping occurs, and - means for adjusting the direction of move- - ment of the wiping means in accordance with the aspect so determined. As applied - to a bed-lasting machine of the kind described in Specification 22630/08, the toe-wiper head is carried bv a vertical slide 20 raised and lowered by a doubleended treadle, the wipers being advanced and closed by a hand lever. Between the slide 20 and the wiper head is a slide 28 movable longitudinally by a hand-wheel to adjust the head for differing lengths of shoes, a slide 32 movable laterally of the shoe, a holder 36, on a transverse pivot, to tip the wipers lengthwise of the shoe, and a sleeve 42, actuated by a crank 52 and yoke, to tip the wipers 18 laterally of the shoe, all this mechanism being substantially as in prior machines. It is found that, normally, the up-wiping movement should be at right angles to the general plane of the fore part bottom. The slide 32 is, therefore, connected to the lateral tipping adjusting means so that the direction of the overwiping and up-wiping movements are conjointly adjusted. The slide 32 is formed with lugs 54 embracing slotted collars guided by a square shaft 58 connected to the crank 52 by spur gearing 64, a, worm 78 and sector, a link 84 and cranks. The shaft 58 is normally fixed, so that as the wiper head rises during up-wiping the slide 32 is moved transversely according to the inclination of the slots engaging the shaft 58.

Title: System of recording or reproducing frequencies within the audible range
Inventor: VINZELBERG BERNHARD
IPC: G11B19/265
Filed: 1953-10-16
Abstract: 776,656. Recording and reproducing sound. VEB. FUNKWERK KOPENICK. Oct. 16, 1953, No. 28640/53. Class 40 (2). Intervals are provided in the reproduction of a recording, e.g. to facilitate the typing of a recorded speech, either by momentarily stopping the apparatus during reproduction or by causing the record to travel faster during a pause in, e.g., a speech, whilst recording. The stopping and starting of the record or the increase of speed are effected automatically by pauses in the recorded signals. As applied to a magnetic recording and reproducing apparatus, during reproduction, when an interval in the reproduced sound occurs, a condenser C1 discharges through a resistance R1 and contacts K4, K5, the potential at the control grid of valve Va<SP>1</SP> becomes more positive, current flows through the valve, the relay Rel1 is energized, closing contacts K2, K3 causing a magnet M1 to be excited which through an armature e, Fig. 5, and coupling pinions c, d, causes the drive of the record to be reversed, until a nut W on a worm R operates a switch S1. The output from the reproducing head amplifier V is shortcircuited by contacts K6, K7. A current source U1 charges the condenser C1 negatively, after a time depending upon the value of an adjustable resistance R2, causing the valve Va<SP>1</SP> to become non-conducting and the relay Rel1 to become dead. U1 is now connected through contacts K1 K2 to relay Rel2 which after a delay connects U1 to magnet M2 to drive the record forward. If there is no interval in the sound, condenser C2 is charged negatively by the output of the amplifier V which acts to make the valve the Va<SP>1</SP> conducting and the cycle begins as with an interval of sound.
