Title: Improvements in apparatus for wrapping rectangular block-shaped articles
IPC: B65B57/06
Filed: 1957-05-16
Abstract: 845,663. Wrapping-machines. HALL, C. T., and MOLINS MACHINE CO. Ltd. May 15, 1958 [May 16, 1957], No. 15594/57. Class 94(1). A wrapping machine has a detector acting, upon failure of the supply of wrapping material, to divert unwrapped articles along a different path from that followed by wrapped ones. The machine wraps rectangular articles by the known method of feeding each of them against a wrapper 64 which it carries through folding means 69. In normal operation wrapped articles arrive on a platform 2 where they are arrested by a moveable stop 34, the platform rising to push each article beyond retaining pawls 3. When a stack of three articles rests on the pawls, a reciprocating pusher 5 forces the top two onto a platform 4 for subsequent cartonning &c. In the event of wrapper failure, a feeler 45, raised periodically and allowed to fall to engage the wrapper portion protruding from one end of the article, enters an aperture 44 in the table 1 its lower end operates a switch 54 whereby a solenoid 55 displaces a peg 22 of a timing drum 21. The displaced peg trips a pawl, Fig. 3 (not shown), and declutches the shaft 26 bearing cams operating the platform 2 and stop 34, whereby the platform and stop remain lowered. Unwrapped articles travel across the platform to a shoot 35 where an oscillating pusher plate 36 transfers them to a stacking table 39. Articles may be directed without wrapper failure by normal operation of a switch 70.

Patent GB-1066593-A (GB)
Title: Improvements in or relating to methods of producing doped solid semiconductor material
IPC: H01L21/00
Filed: 1964-04-16
Abstract: 1,066,593. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 16, 1964 [April 19, 1963], No. 15803/64. Heading H1K. In a method of doping semi-conductors by the controlled addition of a doping substance in vapour form to a semi-conductor in solid, liquid or vapour form, the doping vapour is produced by passing sparks between electrodes at least one of which is at least partly composed of the doping substance, and doped solid semi-conductor material is eventually formed at a location remote from the spark electrode system. The invention is designed to make the rate of generation of doping vapour accurately controllable; this is achieved by control of the spark energy and/or frequency. In Fig. 1, hydrogen is passed from a source 2 through a filter 7 to pipes 13 and 29. Pipe 29 is fed with GeCl 4  vapour from a source 25 and pipe 13 contains the boron-producing spark apparatus 15 either alone or downstream of a source 37 of halogen so that the boron may be entrained in the gas stream in the form of a boron halide. In the similar apparatus of Fig. 2 (not shown), the pipe 13 is omitted and the spark apparatus is in the pipe 29 downstream of the source of semi-conductor-in this case SiCl 4 . In both apparatuses the pipe 29 leads to a chamber 22 in which the doped semiconductor vapour is deposited on a support. The support may be a semi-conductor wafer of opposite conductivity type to the deposited material, and more than one electrode system of the same or different doping substances may be connected in series or in parallel with each other in the apparatus. In Fig. 3 (not shown), a vacuum chamber (60) contains a support (65), a directly heated semi-conductor source (64), and one or more same or different spark electrode systems (68, 69). Doped semi-conductor (74) is deposited, possibly in alternate P and N-type layers by alternate use of P and N-type electrode systems (68 and 69). The vaporized dopant may alternatively be diffused into solid semi-conductor material or dissolved in molten semi-conductor which is subsequently solidified. The invention is also applicable to the doping of A3-B5 compound semi-conductors and may be used to produce diodes, transistors, photo-cells or solid state circuits. Fig. 4 (not shown) depicts the spark apparatus. At least one of its electrodes (87, 88) is a tungsten rod with a boron sheath. However, a pure doping element (e.g. aluminium or antimony) or compound (e.g. a phosphide or arsenide) may be used. In each case any substance other than the required dopant present in the electrodes must either be non-doping or non-volatile. The circuit (Fig. 5, not shown), of the spark electrode system includes a capacitor and a shorting switch across the spark gap. The former controls the spark energy and the latter is used to inhibit glow discharge during the spark switch-off period, since such discharge was found to produce fouling of the electrodes by semi-conductors present in the vapour atmosphere surrounding them.

Title: Improvements in or relating to the preparation of protein products from fish materials
Inventor: MOHLER KLEMENT
IPC: A23J1/04
Filed: 1956-05-22
Abstract: In the production of protein preparations free from undesirable smell and taste, partially dehydrated fish material having a fat content of less than 4 per cent is treated, preferably between 20 DEG C. and 80 DEG C. under reduced pressure, with a solution of an alkali, e.g., caustic alkali, alkali and alkaline earth metal and ammonium compounds having an alkaline reaction, and/or a solution of an acid, e.g., hydrochloric acid in an organic solvent, e.g., ethanol or acetone.  When both alkali and acid treatments are employed they may be in either order and, if desired, in repeated alternation.  Partial dehydration involves reducing the water content of the fish material to 60 per cent or below, by, e.g., vacuum drying or treatment with water-miscible organic solvents. If necessary, the fat content is first reduced to below 4 per cent by treatment with organic solvents. After the alkali and/or acid treatment the protein is isolated by adding alkali or acid to reach the iso-electric point thereof, the solvent then being removed by e.g., pressing, centrifuging or distillation.  The separated protein is purified by washing with one or more organic solvents and is then dried, preferably below 60 DEG C. under reduced pressure.  Steam treatment may replace, or be combined with, washing with an organic solvent.ALSO:In the production of protein preparations free from undesirable smell and taste, partially dehydrated fish material having a fat content of less than 4 per cent is treated, preferably between 20 DEG  and 80 DEG  C., under reduced pressure, with a solution of an alkali, e.g. caustic alkali, alkali and alkaline-earth metal and ammonium compounds having an alkaline reaction, and/or a solution of an acid, e.g. hydrochloric acid, in an organic solvent, e.g. ethanol or acetone.

[Classes 83 (ii) and 83 (iv)] A mandrel, for use in blind-riveting Sc., having a head of oval cross-section as in Specification 504,928, is made by subjecting the circular head of a headed mandrel to side pressure. The head may be made by gripping wire stock by holding dies shaped to form a constriction 5 having a non-circular cross-section, as in said prior Specification, and striking the projecting end by a heading tool to produce a head of circular cross-section. The dies are then opened, the stock fed, and a length cut off. The head is then corrected or flattened by concave dies to produce surfaces 19, Figs. 2 and 3, these dies being arranged in the same machine and acting on said head after the heading operation or being arranged in a separate machine.
