Title: An improved process and apparatus for the electrolytic removal of metal from metallic bodies
IPC: C25F7/00
Filed: 1928-06-05
Abstract: 322,118. Coles, S. O. Cowper-. June 5, 1928. Metals, removing; band conveyer apparatus; electrodes, mounting; preparing and treating surfaces.-In a process for the electrolytic removal of metal from metallic bodies there is added to the electrolyte an abrasive material, such as sand or pumice powder, which lies at the bottom of the bath and through which the blanks operated on are caused to pass. The process is described in connection with an apparatus for pointing needles. A pair of travelling endless chains 3 passing over sprocket wheels 4 are provided at intervals with sockets (not shown) in which rods 8 connecting the chains are inserted. These rods support carriers 9 in which the blanks 10 are fitted. A pair of insulated rails 11 on which the rods 8 rest, and which also serve for connecting the electric current to the blanks, bend downwards over the electrolytic bath 1, thereby gradually introducing the points of the blanks 10 into the electrolyte containing abrasive, and then gradually withdrawing them. Guiding sprocket wheels 12 may also be used for the same purpose. The motion of the upper part of the chain 3 being from right to left, each carrier 9 as it emerges from the bath 1, bears on the curved end of the horizontal plate 14 which has recesses (not shown) for the accommodation of the blanks, and is lifted clear of the rods 8. Each carrier on leaving the rods is supported by its lateral projections 16 adapted to engage grooves 17 in horizontal bars 18. The blanks are clamped against opposite serrated sides of a central block by rubber-faced side blocks operated by rotary collars having a cam action. In using the process for removing the splay from the eyes of needles after stamping the remainder of the needle is coated with a material which resists electrolytic action.

Patent GB-734594-A (GB)
Title: Resilient bonded fibrous materials
Inventor: MERRIMAN PETER
IPC: D04H1/587
Filed: 1952-06-28
Abstract: 734,594. Agglutinated fibrous materials. XETAL PRODUCTS, Ltd. June 12, 1953 [June 28, 1952], No. 16334/52. Class 140. Resilient bonded fibrous material for upholstery and shock-absorbing material consists of a mass of loose resilient fibres bonded together by means of a rubbery reaction product of a polyester and a polyisocyanate'or polyisothiocyanate. The polyisocyanate-modified polyester is applied to the fibres as a non-rubbery reaction product of the polyester and polyisocyanate or polyisothiocyanate containing isocyanate or isothiocyanate radicals which are available for reaction either immediately or upon heating, and the reaction between the polyester and the radicals is then caused or allowed to proceed until a rubbery product is obtained. The fibres may be curled fibres such as hogs' hair or coir fibre ; artificial fibres which react with the binder, such as casein fibres, may be used. The polyester may be prepared from a glycol, a dicarboxylic acid such as adipic acid, and, if desired, a diamine. The polyisocyanate may be an alkyl, aryl, or aralkyl diisocyanate, such as hexamethylene-, naphthalene 1:5-, toluene-, and diphenylmethane 4:4<SP>1</SP>-diisocyanates. To reduce toxicity and premature reaction isocyanates may be used in which some of the active isocyanate groups are in thermolabile combination with hydroxy compounds such as phenol or dimethylol propane or combined with one another by polymerization. The non-rubbery partial reaction product of polyester and polyisocyanate may be deposited on the fibres as a mobile liquid, a solution in a volatile or non-volatile solvent such as ethyl or butyl acetate, tricresyl phosphate, dioctyl phthalate or sebacate. Chlorinated diphenyl, an animal or vegetable oil, e.g. castor oil, may be added. Immediately before use, an agent for effecting completion of the reaction may be added, e.g. water or a glycol, and the speed of the reaction may be increased by adding cobalt naphthenate or an organic base such as pyridine or urea. Sufficient water for the reaction may be present in the fibres or in the air around them. If volatile organic bases are used, they may be introduced as vapour into a mould containing the previously wetted fibre. If polyesters of low hydroxyl value are used, porosity of the rubbery reaction product results from evolution of carbon dioxide derived from carboxyl groups.

Title: Phase detector
IPC: H03D3/24
Filed: 1950-07-03
Abstract: 683,565. Phase difference measuring. PHILCO CORPORATION. July 3, 1950 [July 2, 1949], No. 16539/50. Class 37. [Also in Group XL (c)] A phase detector detecting the relative phase variation between two sources comprises a first rectifier 34 and a parallel resistance capacitance network 36 connected in series across an input from the first source, and a second rectifier 35, second parallel resistance-capacitance network 37 and choke 38 all in series connected in shunt to the first path, the second output being applied across the junction of the first rectifier and network and the junction of the choke with the remainder of the second path. The phase difference is detected as the voltage at the point 18 between the second rectifier and network 37 relative to the earthed junction of the first rectifier and network 36, which voltage is zero in the absence of the second output. The phase detection is moreover independent of amplitude variations of the first output. The choke 38 may alternatively be connected between the anode of the diodes or the diodes of Fig. 1 may both be inverted with their cathodes connected. Further, the circuit portion including diode 35 and network 37 may be inverted (Fig. 2, not shown). The phase detector may be used as shown in a frequency discriminator of the known type employing a locked-in oscillator 12 synchronized to follow the frequency deviation of an incoming frequency-modulated wave but whose phase varies in sense and magnitude with the frequency deviation. The oscillator, class C operated, comprises the first three electrodes of a valve 16 to a further electrode of which the detected phase difference is applied, and due to coupled circuits 21, 29, tuned to the incoming mean intermediate frequency is in phase quadrature with the incoming wave at the mean intermediate frequency, so that the sense as well as magnitude of the phase difference is detected. The controlled oscillator output is developed across a cathode inductor 32. Specification 669,707, [Group XL (c)], is referred to.

Abstract: 1302389 Tape cassette players BELL & HOWELL CO 8 April 1970 [25 April 1969] 16653/70 Heading G5R Multitrack tape cassettes are individually taken from a store, one track played, inverted and another track played, then returned to the store. A stack of cassettes is magazine-loaded into the player 10 and a reject button depressed to start a motor driving a cam gear 57. Cam 53 raises a lever 43 carrying a cassette holder 30 rotatable with a drive wheel 47 which, at the top of its travel, is rotated by a puck to invert the empty holder, rotation being limited by a stop 91. The holder 30 is then lowered and dwells opposite the lowest cassette in the magazine so that an arm 35, driven by the cam gear (Figs. 7 to 9, not shown), ejects the cassette through a spring-loaded shutter into the holder which then carries the cassette down to the play position. The drive motor is de-energized by a follower 59 and switch 63. During play, a shaft 75 is driven to continuously open and close a switch (77) indicating that tape drive is in progress and serving to re-energize the drive motor when play ceases. The cassette is thereupon raised, inverted then lowered for the next track to be played. After play the cassette is again raised and inverted but then injected by arm 37 back into the top of the magazine. Detents (119, 121) are provided on the gear 57  to ensure that the cassette injection and ejection arms 37 and 35 operate on alternate revolutions of the gear.

Title: Improvements in or relating to laundering and other washing processes
IPC: C02F5/02
Filed: 1941-12-29
Abstract: In laundering and other washing processes the softening of the water by means of alkaline reacting substances, for example, carbonate bicarbonates and silicates of soda and potash and hydroxide of sodium and potassium is accelerated by mixing with one or more of the substances finely-divided crystalline or micro-crystalline calcium carbonate or magnesium carbonate, the mixture being added to the water and the resulting precipitate being allowed to remain in the water during laundering.  In an example 1.5 grams of calcined soda is used with from .02 to 2 grams of calcium carbonate per litre of water.  Specifications 507,750 and 22149/39, as open to inspection under Sect. 91, are referred to.
Patent GB-1518320-A (GB)
Title: Menstrual tampons and method of making same
IPC: A61F13/22
Filed: 1977-04-22
Abstract: The tampon consists of a nonwoven (1, 11) and, arranged thereon, a removal cord (2) which is arranged, over one part (2') of its overall length, parallel to the longitudinal direction of the nonwoven (1, 11) and is wound together with it and pressed, while another part (2'', 2''') of the removal cord (2) is bent out at approximately right angles to the longitudinal direction of the nonwoven (1, 11) over one of its longitudinal edges (1'). The tampon is characterised in that the removal cord (2) lies loosely on the nonwoven (1, 11). In this way it is possible to produce a tampon in a continuous manufacturing method, that is to say in a method in which the manufacturing machine in question operates without stop periods. Compared to other products of this type or a similar type, the tampon in this case has the advantage that its removal cord (2) cannot be pulled out from the swollen nonwoven (1, 11), in accordance with its intended use, since the nonwoven (1, 11), as a result of the spirally wound cord part (2'), undergoes a contraction when a pull is exerted on the protruding cord part (2'''), which facilitates its removal. <IMAGE>
