Title: Process and apparatus for mechanically treating a woven tape
IPC: D06H7/02
Filed: 1940-12-19
Abstract: 583,461. Cutting and folding machines. ARMSTRONG, J. J. V. (Stoombandfabriek Naamlooze Vennootschap van Engelen & Evers). Dec. 19, 1940, No. 17879. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 19, 1940.] [Classes 31 (i) and 42 (i)] A woven tape is cut transversely, and the two ends thereby produced are simultaneously folded parallel to the cut, the folding being effected by pressing each end through the full width of the tape into a slot of a work table so that the tape is folded into U-shape in the slot. The knife 2 pivoted at 33 is actuated by a cam 31 to sever the tape, the knife co-operating with a fixed shear blade 3 toward which it is urged laterally by a spring. As the knife descends, a pair of folding blades 4 descend to push the ends of the tape into slots 6, 8, a cam operated lever 39 effecting the movement against the pull of a spring 45. An adjustable screw 41 is provided to determine the length of the folded end. The blades 4 are retracted and members 11, 12 at the sides of the slots are moved inwards to press the folded ends, one or both members forming the sides of the slots being heated. Pressers 5, also cam actuated, hold the ends of the tape during engagement of the tape and the folding blades.

Abstract: 1515467 Position measurement SOC D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE 4 May 1976 [7 May 1975] 18064/76 Heading H3H] The relative position of a scale carried by a first member and detector carried by a second is determined by the position of the image, formed by system 9, 12, of a scale mark 15 on the detector 13. The detector comprises a linear matrix of photosensitive devices which extend over the image length of one scale interval, the scale mark being identified by reference 16 which is also read by the detector. In the embodiment the mark and binary reference number are read by a linear array of 256 photodiodes 19 which in turn are serially scanned by clock pulses, a shift register takes the most recent results and a pattern recognizer halts scanning pulses incrementing counter 35 when the scale mark is found. Scanning continues to read the identification code into the register in response to gating pulses derived from division circuits 40. The contents of the register 26 are transferred to register 48, which together with register 47 connected to counter 35 form the output stage.

Title: Improvements in or relating to animal foods containing fish
Inventor: BECKWITH GERTRUDE HUMPHREY
IPC: A23K1/10
Filed: 1951-07-31
Abstract: The semi-solid slurry obtained by coagulating and concentrating, e.g. to 50 per cent solids, the liquor pressed from fish in the preparation of fish meal or from fish livers or the like which have been digested with proteolytic enzymes is converted to a dry animal feed by the addition of a phosphate capable of combining with several molecules of water.  Other protein-containing feeds, e.g. soya bean meal, fish meal, meat scraps, may be incorporated.  The phosphates employed are exemplified by anhydrous disodium phosphate, which takes up water to form the heptahydrate, and dicalcium phosphate in the presence of ammonia, which takes up water to form the heptahydrate of calcium ammonium phosphate.  The time for hydration of the phosphate may be reduced by incorporation of a wetting agent, e.g. a sulphonated fish or vegetable oil or a polyoxyethylene sorbitol or glycol fatty acid ester.  Lumping of the dry product may be prevented by incorporation of calcium stearate.

Title: Improved method of manufacturing photocells with small-area cathodes and cells so manufactured
IPC: H01J40/06
Filed: 1957-06-11
Abstract: 806,339. Photo-electric cells. FERNSEH G.m.b.H. June 11, 1957 [June 9, 1956], No. 18387/57. Class 39(1). In a method of manufacturing a photocell having a small, accurately determined cathode area, a photocathode is formed having an area substantially larger than that required and subsequentally all but the selected area of the photocathode required to remain photosensitive is covered to prevent photoemission therefrom. The initial large-area cathode 5 may be formed by evaporating a layer of antimony upon the end of the envelope 1 from a metal ring 4 carrying antimony beads and arranged to be heated by high-frequency currents induced in it, introducing caesium into the envelope and completing the cathode in known manner. Then a screen 6 may be placed in front of the cathode and further antimony evaporated until those parts of the cathode not covered by screen 6 are practically opaque, after which the screen is returned to position 6<SP>1</SP>. Alternatively an apertured screen may be placed adjacent the large-area cathode so as to leave only the selected area of the cathode free to emit photoelectrons. As shown, the cell includes an entrance diaphragm 3 and a multiplier section 2.

Abstract: 1,241,883. Centrifugal separator. G. EBERLE [trading as ANDREAS HETTICH]. 10 April, 1969 [13 April, 1968], No. 18426/69. Heading B2P. A centrifuge bucket for receiving a fragile sample test vessel, for example a blood bottle, is so constructed as to compensate for the pressure exerted on the interior surface of such a test vessel during centrifuging- of the contents thereof. As illustrated in Figure 1, a centrifuge bucket 1 comprises a threadably removable cover 2 and a threadably removable lid 3 having a central aperture 3' for receiving a test vessel 22. The interior of the bucket is provided with a lining 4 of rubber. Formed within the wall 17 of the bucket to extend longitudinally thereof is at least one bore 7. A piston 6 is contained in the or each bore and is retained therein by a projection 5' formed on a thickened edge portion 5 of the lining. The or each bore communicates via a bore 10, an intermediate space 11 and a bore 12 with a pressure compensating space 13 defined by the rubber lining and by a bucket end wall 11' and provided with radially extending channels 13'; the various bores, spaces and channels are filled with liquid so that, upon application of centrifugal force to the bucket, the or each piston exerts on the liquid in its associated bore a pressure which is transmitted through the liquid to act in directions 14 and 16 upon the lining, and hence upon the exterior of the test vessel. in opposition to the centrifugal pressure exerted in direction 9 on the interior of the test vessel by contents thereof which are being centrifuged. The bore associated with the or each piston also may contain a spring 8 for moving the piston in the direction 9' when the application of centrifugal force is terminated, an air vent channel 20 allowing such return movement of the piston. The rubber lining may have a varying thickness in order that the forces exerted by the liquid can be so distributed over the surface of the test vessel as to give protection to those portions 19 thereof which are especially prone to breakage and in order to prevent the test vessel from sliding out of the bucket by reason of the force exerted on the test vessel by the liquid in opposition to the centrifugal force. The outside of the bucket may be provided either with grooves, see Figure 2 (not shown), or with pins for cooperating with corresponding pins or grooves provided on the head of a centrifuge (not shown) in order that the bucket may pivot freely during centrifuging.

Abstract: 153,073. Barr & Stroud, and French, J. W. July 28, 1919. Toothed gearing. - The shutter provided for screening a film in its stationary condition from the heat of the projecting-light is operated by the movements of a toothed driven wheel which is mounted in such a manner that it is capable of restricted movement from a normal position in opposition to a resistance. In the construction shown in Fig. 5, ordinary toothed wheels A<2>, B<2> are employed, the driven wheel B<2> being mounted on an arm K capable of restricted angular movement about the axis of the driving wheel A<2> against the action of a spring E<2>. The rotation of the wheel B<2> is resisted by a spring L or by a friction disk so that on rotating the wheel A<2> the force applied tends to carry the wheel B<2> and arm K downwards. This movement, which may be restricted by a stop, is transmitted through a link 5 and crank 3 to the shaft G carrying the shutter H. After this movement has taken place, power is transmitted in the ordinary manner through the wheels A<2>, B<2>.
