Title: Improvements in or relating to apparatus for wrapping apples or like articles
IPC: B65B11/54
Filed: 1952-02-22
Abstract: 733,161. Wrapping articles. CHAMBERS, B. W. Nov. 26, 1952 [Feb. 22, 1952], No. 4743/52. Class 94 (1). [Also in Group XI] Apples &c. are pressed by hand against a wrapping material 2, softened by a heater 22 as it is cyclically and automatically drawn over an opening 4 whereby the material stretches and allows the apple and material to pass through the opening 4. The apple is then twisted by hand to seal the material at the neck where it is then severed by advance of the heater element 22. The sheet 2 of material is drawn over a baize covered table 2 across the opening 4 therein by co-operating rollers 6, 7, the roller 7 being timed to be moved away from the baize covered roller 6 by cams 6 to stop the feed when the apple is to be pressed down. The rollers 6, 7 pass the apertured film to waste. The electric heater 22 on a lever 20 is urged in underneath the film over the opening 4 by a spring 23, a cam actuated chain 24 permitting the swing and a further swing to allow the heater to advance further to sever the neck. A cam operated clamp 17 presses on the surround of the film over the opening 4 to hold it when the apple is to be passed through. A small metal roller 34 may be interposed in the feed of the sheet material, to which the cut out film may adhere, and so prevent contraction on passing to the roller 6. The heating current is regulated by an automatic switch 32, Fig. 6 (not shown). A hand lever 37 allows the heater 22 to be held away from the opening 4 during adjustment of the sheet.

Abstract: 616,246. Mechanical scanning arrangements. ROWELL, J. W. March 16, 1944, No. 4932. [Class 40 (iii)] Scanning means for television or facsimile or for use as a light chopper comprises a pair of discs 100, 101, which are mounted about spaced axes 150, 151 and rotated in opposite directions, the disc 100 having inclined rows of holes or slots such as 1 to 36 and the disc 101 having correspondingly numbered rows of holes or slots disposed in spiral formation, so that, as the discs rotate, the intersections of the slots or lines of holes in the two discs scan an area lying about the line joining the axes, the direction of scan being parallel to that line. To manufacture discs, a master disc 100 is employed with a suitable straight-edge guide for forming the holes or slots in a master disc 101, and the two master discs may be copied photographically. The rows of holes or slots in the disc 101 are preferably cut so as to produce interlaced scanning, the lines being scanned in the order 1, 3, 2, 4, 6, 5 &c.

Abstract: 252,764. Hale, G. W., and Radio Engineering Co., Ltd. Feb. 23, 1925. Thermionic amplifiers.-A variable intervalve coupling comprises an inductance or choke coil one end of which is connected directly or through a condenser with the anode of one valve, an intermediate tapping is connected directly or through a condenser with the grid of the following valve, and the other end of the coil is connected to a point in the circuit at zero oscillating potential. The coupling is varied by relatively varying the inductances of the two parts of the coil by axial movement within the coil of a magnetic or eddy-current core. Fig. 4 shows a construction for audio-frequency coupling a magnetic core 20 sliding in a tube 26, the magnetic circuit being completed through iron stampings 25. The circuit for audio frequency coupling between valves 1, 2, Fig. 5, may be modified by connecting the intermediate tapping directly to the grid 8 and the anode 5 through a condenser so that the high-tension supply does not traverse the choke 4 but is provided with a resistance or choke in a separate circuit. As applied to high-frequency amplification, a condenser 19 is connected in parallel to tune the coil 4 and an eddy-current core or shield of copper. aluminium or silver is preferably employed. The core 20 may be moved by hand or by a solenoid or electromechanical device energized in accordance with variations in the output load. The valve 27, Fig. 5, is so arranged that an impulse exceeding a predetermined amplitude occurring at the anode 29 of valve 2 causes relay 31 to be operated and closes the circuit of electromagnet 35 causing a clutch 40 on a continuouslydriven spindle 41 to release and lower the core 20. In modifications, the number of loud-speakers connected in circuit is arranged to determine the position of the core 20.

Title: Bleaching compositions
Inventor: ADLER LORENZ STEPHAN
IPC: C11D3/39
Filed: 1958-02-20
Abstract: A powder composition which, when mixed with water or aqueous hydrogen peroxide, yields a cream or paste suitable for bleaching hair comprises a metallic peroxide, a water-soluble persulphate, ammonium bicarbonate and a water-insoluble thickener.  The metallic peroxides used are those which, on addition to water, form an alkali and generate hydrogen peroxide, e.g. alkali and alkaline earth metal peroxides, sodium peroxide and calcium, barium and magnesium peroxides mixed with sodium peroxide being particularly suitable. Ammonium persulphate is preferably used although other water-soluble persulphates such as the alkali metal persulphates are also suitable. The insolubility of the thickener may be such that an adequate amount of it remains in solid form lin the bleaching composition, suitable thickeners being calcium carbonate, magnesium carbonate, plaster of Paris, talc, kaolin and bentonite.  Desiccants, e.g. anhydrous sodium sulphate, humectants, e.g. sucrose, glucose and lactose, and buffers, e.g. ammonium bisulphate, potassium hydrogen phthalate, tartaric acid, ammonium hydrogen tartrate and acid ammonium salts of polybasic inorganic and organic acids such as diammonium phosphate, may be included in the composition.  The composition preferably contains 2-30% by weight of metallic peroxide, 5-25% by weight of persulphate, 5-40% by weight of ammonium bicarbonate, 10-85% by weight of thickener, 5-30% by weight of desiccant and 2-10% by weight of humectant.  The powder composition is preferably dissolved in 20 volume hydrogen peroxide to give a solution containing at least 2% by weight of metallic peroxide and having a pH within the range of 8,5 to 9.  Examples are given.  The Provisional Specification refers to the use of powder compositions comprising (1) an inorganic peroxy compound, i.e. a solid inorganic compound (or mixture of compounds) containing peroxide oxygen which dissolves in water with the liberation of hydrogen peroxide, such as alkali and alkaline earth metal peroxides and metallic percarbonates and perborates, (2) an ammonium salt, e.g. ammonium nitrate, sulphate, chloride, bicarbonate, acetate, bisulphate or persulphate, and (3) a water-insoluble thickener.
