Title: Improvements in or relating to the bleaching and dyeing of hair
IPC: A61Q5/08
Filed: 1966-11-23
Abstract: The damage to hair during bleaching and dyeing with compounds yielding active oxygen, e.g. hydrogen peroxide, melamine perhydrate, sodium perborate and sodium persulphate, is reduced by treating it with one or more aminopolyphosphonic acids having the formula: <FORM:1102734/D1-D2/1> in which Z and Y represent a hydrogen atom or an alkyl radical containing 1-4 carbon atoms and R4 and R5 represent a-PO3H2 group or a group having the formula: <FORM:1102734/D1-D2/2> or a water-soluble salt or ester thereof optionally in admixture with a compound having the formula: <FORM:1102734/D1-D2/3> in which X is -OH or NH2, R, is an aryl radical, an aliphatic radical having 1-5 carbon atoms or the radical: <FORM:1102734/D1-D2/4> and R2 and R3 are hydrogen atoms or alkyl radicals having 1-5 carbon atoms, or a water soluble salt thereof. Mixtures containing the aminopolyphosphonic acids and organic acylation products of phosphorous acid in the weight ratio of between 3:1 and 1:3 may be used.  Suitable watersoluble salts are the sodium, potassium, ammonium and mono-, di-and tri-ethanolamine salts.  The compounds may be applied to the hair before or during bleaching or dyeing as a solution, gel, cream, powder which may also contain thickeners, wetting agents or cosmetic additives, e.g. fatty alcohols containing 12 to 14 carbon atoms, fatty alcohol sulphates containing 16 - 18 carbon atoms, the reaction product of 1 mol of stearyl alcohol with 8 mol of ethylene oxide, paraffin oil, glycerine, ammonia, soda, oxidation dyestuffs and cetyl trimethylammonium chloride.
Patent GB-1091080-A (GB)
Title: Improved method and device for the production of random asbestos webs
IPC: D04H1/736
Filed: 1964-12-28
Abstract: Webs of evenly mixed asbestos and other longer fibres, e.g cotton or rayon are prepared by passing mixed and opened fibres in an accelerating air stream from a heater to foraminous drums prior to being carded.  Partially opened asbestos fibres are further opened in a vertical opener 2 and blown into containers 4 from which they may fall onto a conveyor 7 upon which a web of cotton or rayon fibres has already been laid from a lap 8.  The conveyor 7 and delivery devices associated with the containers 4 operate intermittently so as to supply only sufficient fibres to an opener 10 as provide one charge. After being treated in the opener 10 each charge is deposited on a conveyor belt 12 from which a double hopper feeder 13 transfers the charges to a Kirschner heater type scutcher 16 following which a lap is formed at 21.  Fibres are sucked from the heaters of the scutcher by air drawn through perforated drums and by reason of the duct reducing in section between heater and drums the air stream is accelerated, thereby maintaining the heavy asbestos fibres in the air current.

Title: Cameras employing interchangeable automatic exposure control devices
IPC: G03B7/01
Filed: 1974-12-05
Abstract: 1465380 Automatic exposure control NIPPON KOGAKU KK 5 Dec 1974 [6 Dec 1973] 52659/74 Heading G2A S.L.R. camera has a pentaprism view-finder attachment A which incorporates light metering and automatic timing circuitry that is powered by the camera body B, receives a starting signal therefrom and transmits like to a shutter closing command. The body also includes a manually set, electronically controlled, shutter timer and can be switched to respond either to the attachment or to its built-in timer. In a first embodiment, Fig. 2 a photo-conductive element 1 logarithmically varies its resistance to alter the bias on capacitor 3 and the manually operated resistor 5 is set to represent film speed and aperture. When the shutter release is actuated switch SW1 opens and the potential stored across 3 alters the charging current presented to capacitor 10 such that the current is proportional to the linear light value. The constant of proportionality is controlled by 5 via linear expanding circuitry 7, 8 and thus the charging rate of 10 integrates both inputs. The voltage across 10 is compared with a reference in Schmitt trigger circuitry 11-13, the reference being calibrated by resistor 25. When the shutter release is operated in the camera, magnet Mg opens the shutter and current continues to flow via C6 to hold the shutter open until the exposure period is terminated as described above. A timing circuit 17-20 is also provided in the body and is set manually by 15. This may be operable by switching to "M" In a second embodiment (Fig. 4) the stored e.m.f. representing the light intensity is presented to a differential amplifier and the film speed/aperture setting value is used to provide a variable amplitude reference signal that is also input to the differential amplifier. The output from this amplifier charges a timing capacitor, the e.m.f. across which controls the duration of the "shutter open" signal which is fed to the body as before. This embodiment includes a light value indication.

Title: Elevator control system
IPC: B66B1/14
Filed: 1973-11-14
Abstract: 1453080 Automatic control of elevators HITACHI Ltd 14 Nov 1973 [20 Nov 1972] 52823/73 Heading G3N In a multi-car lift control system, in which a hall call, when registered, is allocated either to a specified car or to a specific group containing a plurality of cars operating in adjacent hoistways, the first car of the group to pass the hall in the requisite direction responding to the hall call, the hall call is cancelled only when either the specified car, or member of the specific group is decelerating in the vicinity of, or stops at, the hall, stoppage of other cars or groups at the hall in response to car calls not enabling de-registering of the call. The allocation of a hall call to a given car causes energization of a corresponding relay, Fig. 10 (not shown), energizing a guide lamp for the hall and direction, Fig. 11 (not shown), and enabling the energization of one or other of relays (USTA, DSTA), Fig. 12 (not shown) when the car stops in response to the hall call. Contacts (DSTAa2), or (USTAa2), Fig. 13 (not shown) then enable the hall call registration holding relay (e.g. HC9D) to be by-passed and the hall call is cancelled. Should any car stop at the hall in response to a car call, relay (CSTA Fig. 12) is energized, but the hall call is not cancelled. In the embodiment of Figs. 14, 15 (not shown), the relays of (Fig. 10) for each car, {e.g. cars A, B}in a group of adjacent cars have contacts e.g. (Ry9UAa2, Ry9UBa2), (Fig. 14), enabling the cancellation of the hall call by means of relays (USTA), or (DSTA), such contacts for all of the cars in the group, for each hall and direction being in parallel, (Fig. 14). All the cars in a group may share a single guide lamp, (Fig. 15), for each hall and direction. The hall call may be allocated to a specific car, or only to a specific group. A hall call may be allocated to the nearest car to the hall, or there may be provided a zoning system in which a given car is allocated all hall calls between its notional position, and that of the car ahead of it, the cars being regarded as being on a ring, see Figs. 1-6 (not shown). The notional position is advanced with respect to the actual position by 1, 2, or 3 floors depending upon the car's speed, and is also advanced by zero, one, or two floors as a function of the number of calls allocated to the car, the average number of calls per car in the system, and the distance between the car and the succeeding car.

Title: Proximity detecting apparatus
Inventor: ICHIMORI MASUO
IPC: H03K17/955
Filed: 1965-12-13
Abstract: 1,088,919. Electro-physical measurement. TATEISI ELECTRONICS CO. Dec.13, 1965, No. 52881/65. Heading G1N. [Also in Division H3] A proximity detector of the capacitative probe type for detecting, e.g. the level of powder in a tank, comprises a transistor connected in a form of Colpitts oscillator, the effectively inductive circuit of which is shunted by the variable capacitance of the probe so that the oscillator ceases to oscillate when this capacitance increases beyond a set value. The effectively inductive collector/ base circuit of the oscillator 12 comprises an inductance 24 shunted by the capacitance (represented at 29) of the probe 28, this parallel tuned circuit being in series with a capacitor 26. The two capacitative branches of the oscillator circuit are respectively, the capacitor 13, and the capacitor 20 in series with a parallel tuned circuit 14, 16. It is shown that by suitably proportioning the several tuned circuits so that the normal frequency of oscillation is slightly lower than the resonant frequency of inductance 24 and probe capacitance 29, oscillation will cease sharply as the increase in probe capacitance causes these two frequencies to approach coincidence. In Fig. 1 (not shown) the output of the oscillator is amplified (42), and rectified (46) to key a transistor (48) on or off. A low-voltage discharge tube (38) is connected between probe 28 earth to protect the oscillator from static charges induced on the probe.

Title: Expanded plastic moulding machine
Inventor: KRACHT GERHARD
Filed: 1965-12-20
Abstract: 1,091,651. Moulding foamed plastics. SWEDISH CRUCIBLE STEEL CO. Dec. 20, 1965, No. 53888/65. Heading B5A. The annular cavity 83 of a mould 12 is supplied with beads of plastics material, e.g. polystyrene, which are expanded by steam to form an annular foamed plastics article. The mould is supported on a foundation 22 extending into a pit 26, and comprises an outer wall 48, a hollow cylindrical core 82, a base 44, and a cover 14 pivoted at 162 and opened and closed by an hydraulic motor 18. The mould is surrounded by a steam supply manifold 60, a cooling water supply manifold 62 and a manifold 58 which receives condensate from the mould cavity. Perforated walls 70 and 94 are located adjacent the outer wall and the core, and an annular perforated bottom wall 74 is located above an annular vertically reciprocable perforated plate 102. When the beads have been placed in the mould and the cover closed down and secured by a number of circumferentially spaced latching devices 16, steam is passed from the manifold 60 into the mould cavity via ports 54 and the perforated wall 70; steam is also fed to the hollow core from a pipe 206 and passes through ports 84, 86 and 88 and the perforated wall 94 to the mould cavity. Condensate passes through the annular perforated plate 102 and passageways 107 to the condensate manifold and flows to a drain pipe 128 which also receives condensate from the hollow mould core via a port 132. Condensate is also received in a manifold 188 and drained away. After the steam treatment, cold water is fed to the mould cavity via the manifold 62 and ports 56, and also via a manifold 186 and branch pipes connected to ports in the cover 14. Such cooling causes shrinkage of the foamed body which detaches itself from the cavity walls. The cover is then unlatched by operating hydraulic drive units 214 which retract levers 220 from engagement with pins 218, and then opened by the motor 18. The foamed article is then removed from the mould by lifting the annular plate 102 by means of hydraulic motors 20, which raise the plate to the top of the mould cavity. In a modified construction, Fig. 6, not shown, the mould comprises semi-cylindrical halves (250, 252) hinged together and provided with integral semicircular closure plates (282, 284) having filling ports (308) closed by plugs (310). The mould halves are opened by a motor (276), Fig. 4, not shown, and gearing which includes quadrant worm gears (256, 258), Fig. 7, not shown, on hinge bosses (246, 248), whereby the moulded article and the hollow core (324) of the mould can be removed horizontally. The mould core is centred in the mould by a head (402) vertically reciprocable by a motor (396) carried in a base structure (382).

Title: Echo check circuit
IPC: B41B27/00
Filed: 1973-11-22
Abstract: 1422835 Printers XEROX CORP 22 Nov 1973 [24 Nov 1972] 54231/73 Heading G4H [Also in Divisions H2 and H3]  In a non-impact character printer employing a plurality of flash lamps to illuminate selected characters from character sets moved relative to the lamps, an echo check signal indicating a lamp has flashed is generated in response to a signal which changes in amplitude between limits within a time that determines the duration of the echo check signal. Each lamp covers say 4 or 6 character positions along the line, a character set being provided circumferentially on a rotating drum for each position, the sets for a given lamp occupying different sectors of the drum. The lamps are flashed to project character images for electrostatic printing at times determined by comparing character data from a computer with a drum position counter to produce flash command pulses. The echo check signals are supplied to the computer to cause abort, reprint and/or flagging of line or page if an echo check signal is produced without a flash command pulse or vice versa. Figs. 4a, 4b, show a circuit provided for each lamp. A flash command pulse 26 at the left goes via a transistor switch 31 and an isolation transformer 32 to turn on transistor 34 to discharge a capacitor 38 into the gate of an SCR 35. (31, 34 and 35 are reverse-biased for noise-rejection.) SCR 35 fires so that a capacitor 39 discharges via a transformer 40 to energize sparker and trigger electrodes 43, 44 in the lamp 4 which flashes with discharge through it of a capacitor 50. A pulse is produced via a transformer 51 to cut off transistors 55, 56 and turn on transistor 57. A ramp voltage is produced by 57 in conjunction with a capacitor 58 and resistor 59 to feed a NAND gate 63 also fed from transistor 56. The output of NAND 63 is inverted 67 to provide the echo check pulse 65.

A derrick for facilitating the connection of flexible hoses 12 leading from a fixed pipe installation to the manifold 21 of a ship comprises a tower 1, up which fixed pipes run, mounting main and auxiliary booms 4, 29 manipulatable by winches to position the hoses 12 adjacent the ship's manifold. The ends of the hoses are mounted on a trolley movable on a beam transversely of the auxiliary beam end. Small and large counterweights 75, 74 are secured to an intermediate part of the main boom by cables 69, 70 which run from a fixed central point 76<SP>x</SP> at the top of the tower over pulleys 71, 71<SP>x</SP>, 67, 68. The arrangement is such that with the main boom vertical the weight 74 is supported on stops 76 while the weight 75 acts to apply a lowering force to the boom due to the position of the attachment of the cables to the boom. As the boom is released by its hoisting winches it lowers so that the weight 75 rises to engage the weight 74 so that both are effective as counterweights to the boom as it extends.
