Abstract: 910,080. Endless sound-tape cassettes. TEFI WERKE G.m.b.H., [trading as TEFI WERKE G.m.b.H. & CO. KOMM.-GES.]. Aug. 25, 1961 [April 19, 1961], No. 30724/61. Class 40 (2). An endless sound-tape, the majority of which is coiled at 6 on a single-cheek spool 4, has a portion 7 led from the inside of the coil, over the coil and down to coil level before emerging through a slot (Fig. 3, not shown), extending in an external loop adjacent transducing means (not detailed) and returning through a second slot to the outside of the coil 6. To prevent tape migration from its designed path, a tubular member 16 and a pin 15 attached to the reel 4 co-operate to provide a barrier across which the lifted tape-portion 7 cannot pass. Felt pads 20, 23 prevent the coil 6 from rising clear of the spool during transport. For play, a machine member, driving the spool by splines 5, lifts the spool just clear of a rib 3 when the cassette s loaded to the machine (not detailed) and thereafter locates the spool.

Title: Improvements in and relating to the production of dietetic preparations
IPC: A23J7/00
Filed: 1931-11-10
Abstract: A nutritive product containing enzymes, vitamin B, and amino acids and bases is prepared from press yeast by treating a small quantity of the yeast with a sterilized solution of cane sugar at the optimum temperature for fermentation, e.g. for 30 hours at 30 DEG  C., carbon dioxide and alcohol being produced.  A larger quantity of yeast is then added, the carbon dioxide which fills the vessel preventing the entry of bacteria, and when fermentation is completed, e.g. after a further 24 hours, cane sugar is added in quantity sufficient to allow autolysis and to favour plasmolysis of the yeast and to reduce the adverse effect of the alcohol present on the autolysis, e.g. a 10 per cent solution of sugar and a temperature of 45 DEG  C. are employed, the alcohol present acts antiseptically and facilitates subsequent filtration.  The product is finally filtered and the colloidal fluid obtained is dried, e.g. at 65 DEG  C. and under vacuum, and powdered. Lactose may be added during the drying.

The extensions 8 may be dispensed with by having the ends of the arms 7 offset and providing them with vertical slots. The shelves are mounted with the sections 4 at an angle by means of bolt openings 14, 15 in the standards and cross-braces respectively, and with the main settings horizontal by means of bolt openings 14, 16.

Title: Improvements relating to spectrographic arc alignment
Inventor: DAVIS HERBERT MACDONALD
IPC: G01N21/67
Filed: 1949-12-05
Abstract: 677,739. Automatic control systems for arcs. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 1, 1951 [Dec. 5, 1949], No. 31204/49. Class 38 (iv). The negative end of an arc is maintained on the optical axis of spectrographic apparatus by controlling the position of the negative electrode. In Fig. 1 an are is produced between carbons 3, 4, the negative carbon 4 carrying a pellet of a sample for analysis. An image of the arc is produced by a lens 2 upon a spectrographic slit 1a and a further image is produced by a lens 5 upon a divided photo - electric cell 6. The apparatus is initially set up so that when the lower extremity of the arc is coincident with the optical axis AA of the spectrograph, the image of the arc falls equally on the two elements of photocell 6. Thereafter any transverse deviation of the lower extremity of the arc results in unequal illumination of the two elements of the photocell which, through a push-pull amplifier including valves V<SP>1</SP>-V<SP>6</SP>, Fig. 4, causes transverse movement of a platform 10, carrying electrode 4, in the appropriate sense to bring the lower extremity of the are back to the optical axis. The position of platform 10 is controlled by a moving coil 18, Fig. 3, operating in the field of an electromagnet 2 As shown in Fig. 4, the two elements of the photo-cell (here marked PC) are alternately associated with amplifier input valves V<SP>1</SP>, V<SP>2</SP> by a commutator SW<SP>1</SP>, the amplifier output to a winding 19a of moving-coil 18 being reversed by a commutator SW<SP>2</SP> driven in synchronism with commutator SW<SP>1</SP>. The arrangement is such that upon unequal illumination of the photocell elements, winding 19a becomes energised in a sense and to a degree corresponding to the sense and magnitude of the deviation. A further winding 19b of moving-coil 18 which generates a voltage dependent on the velocity of movement of platform 10 is connected to points ff at the amplifier input to provide velocity feed-back, adjustable by a rheostat R<SP>5</SP>. Use of two separate photo-cells is referred to and a mask may shield the photo-cell or cells from the upper and central part of the arc. A filter may be provided to make the photo-cell responsive only to a predetermined part of the spectrum.

Each arm of a load lifting or supporting fork comprises sections 4, 6 hinged about pins 5, 7 and provided with releasable catches for retaining the sections in coaxial alignment with the arm at right angles to the plate 1. A plate 41 pivoted on the section 6, is provided with a lip 43 which engages a pin 12 on section 4, and a hook 42 which, when sections 4, 6 are aligned, surrounds pin 7, the plate being pivotable to the released position shown in Fig. 3, against the action of spring 44, by a manually operable lever 23, a rod 26 and a bell-crank 31. With the parts in the position shown in Fig. 6, this movement of the plate 41 is prevented by a wedge plate 14 located between the hook 42 and pin 7, and carried by a vertically slidable block 13, but when the aligned sections 4, 6 are swung out to a position perpendicular to plate 1, a pin 16 on block 13 is aligned with a hole (not shown) in bracket 2 allowing the block to be moved downward by a knob 48 (Fig. 3) to free the plate 14 from the hook, whereby subsequent actuation of lever 23 unlocks sections 4 and 6. The upper surface of the arm is provided with rollers 47 (Fig. 4). The Specification states that the arms can either form the fork of a fork lift truck, or be mounted for vertical movement along a mast.

Abstract: 159,673. Schofield, J. Dec. 16, 1919. Yarns, beaming; lease-rods.-To facilitate the beaming of warps, the creel frames 1,2, normally arranged in V-form, and rotatable about vertical axes 3, 4, support several creel elements 6, which can rotate about pivots 7 in the creel frames and comprise end pieces and intermediate vertical slots arranged in parallel rows 5, 9, 8, the bobbins being suspended between the slots. The inside bobbins are filled bv the operator, whilst the warp is being unwound from the outside bobbins. The beam is then stopped and after the ends from the outside bobbins have been cut, the creel frames are turned into a parallel position, as shown in full lines, by lever mechanism operated from a wheel 27 driven by a wheel 24 and handle 23. Then the individual creel elements 6, which are stepped at the ends and intergear, are rotated so as to bring the filled inside bobbins to the outside of the creel, the creel frames are next moved back to their V-form, the lease is taken and the ends from the new bobbins are pieced to the ends on the beam, and then beaming proceeds. Pivoted lease rods are employed in these operations. The creel elements are turned about their pivots 7 by bevel gearing operated from a hand-wheel 22.
