Abstract: 1520431 Copy-holders G FRIEDMAN 24 Sept 1975 [26 Sept 1974] 39112/75 Heading B6W A line indicator is moved relative to the copy by means of an endless belt driven by a reversible electric motor, there being provided two actuating means (e.g. keys) for starting the motor and a stopping means, whereby when the first actuating means is momentarily operated the motor is driven and a timer of the stopping means is also actuated so that after a predetermined time the motor is stopped, the timer being adjusted for desired line-spacing. If the second actuator is used, the motor is driven until it is released, to enable valuable spacing to be dealt with. The motor may be a synchronous motor, or a stepping motor controlled by a pulse generator, the stopping means comprising a counter. The pulse generator may comprise a rotatable disc with a series of holes and an electro-optical scanning member. In another form, the stopping means compares a signal representative of the position of the indicator with a signal representative of its desired position, and stops the motor when the signals are of the same value. In another form, an electro-optical scanner fitted to the indicator detects the passage of a line of text and stops the motor.

Title: Forming Coatings on Articles of Microcellular Polyurethane Foam.
IPC: B29C44/14
Filed: 1967-08-25
Abstract: 1,197,624. Polyurethane foam articles with integral skins. DAVIDSON RUBBER CO. Inc. 25 Aug., 1967 [29 Aug., 1966], No. 39271/67. Heading B5A. A polyurethane foam article covered with an integral skin of non-porous polyurethane and a film of a plastics material of a different chemical composition is made by coating a mould cavity with a thin film of plastics material, injecting a microcellular polyurethane foam precursor into the mould cavity, closing the mould, foaming under conditions such that a thin skin of non- porous polyurethane is formed on the foam and this skin is bonded to the film and removing the article from the mould. The plastics film may be pigmented to yield a coloured surface on the article, or the film may form an intermediate layer on to which a top-coat is applied e.g. by spraying. The foam preferably has a density of 10-40 lbs. per cubic foot, and may contain inserts placed in the mould before addition of the urethane composition. The process may be used to form automobile arm rests, sun visors and other padded trims; the covering film in the examples being a vinyl acrylic polymer.

Title: Process for the heat treatment of synthetic polymeric films
Inventor: LAST ANTHONY GRAHAM MARSHALL
IPC: B29C48/08
Filed: 1963-10-07
Abstract: 1,025,656. Heat treating oriented films. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 24, 1964 [Oct. 7, 1963], No. 39403/63. Heading B5B. An oriented film of a synthetic organic thermoplastic crystallizable polymeric material is heat-treated in a continuous manner to render it substantially sag-free by causing the film to travel around and in contact with the peripheral surface of a first rotating roll which is maintained at a temperature (below the melting point of the film) which would cause the film to shrink laterally in the absence of any lateral restraint, applying lateral restraint to the film over at least part of its travel round the surface of said first roll whereby the width of the film remains constant, then permitting the film to relax by a controlled amount in at least the longitudinal direction by passing it around at least one second heated roll rotating at a peripheral speed less than that of the first roll and quenching the heat-treated film. The term " oriented film " is defined as a film which has been drawn in one direction to induce molecular orientation in that direction or biaxially in the longitudinal and transverse directions simultaneously or in sequence. Lateral restraint may be applied to the film by holding the edges of the film against the roll by means of two elastomeric surfaces moving in the same direction and at the same speed as the film, the surface being spaced apart laterally with respect to the longitudinal axis of the film. They preferably do not have an independent drive and are driven by the roll via the film. The surfaces may be provided by endless rubber belts of Vee or rectangular cross-section travelling around pulleys. Alternatively lateral restraint may be applied to the film by electrically earthing the peripheral surface of the roll and to deposit an electrostatic charge on the surface of the film which does not contact the roll. The charge may be deposited along the edges of the film at least over the initial part of its travel around the roll, or it may be deposited along a line extending across the width of the film at or near the line where the film first contacts the roll. After passing over the roll, the charged surface of the film is discharged by contacting it with earthing means (or causing it to pass very near to earthing means) before passing it to the next stage of the process.

Title: Improvements in or relating to devices for measuring pulse duration
IPC: G04F10/10
Filed: 1968-08-23
Abstract: 1,242,732. Measuring pulse duration. ROBERT BOSCH G.m.b.H. Aug. 23, 1968 [Aug.24, 1967], No.40330/68. Heading G1U. Apparatus for measuring the duration t i  of a pulse 10 comprises a pulse shaper 14, a rampvoltage generator 16 controlled by the output of the pulse shaper 14 to provide a pulse whose peak value is proportional to t i , a storage capacitor 22 which stores this peak value and a meter 24 connected to capacitor 22 via an impedance matching circuit 23 to indicate the stored value. The apparatus may be used to continuously monitor the duration of pulses in a pulse train. The discharge path for capacitor 22 provided by impedance matching device 23 has a high resistance and so to allow the capacitor voltage to follow decreases in the duration of successive pulses a further discharge path 26 is provided, the opening of which is controlled by a timing element 25 triggered for a fixed period t y  by the trailing edge of rectangular pulse 15. In Fig. 2 the output of the ramp generator is prevented from falling during the period t v  whilst simultaneously the discharge path is opened so that if the peak voltage attained by ramp generator 16 is now less than the voltage on capacitor 22, that capacitor can discharge to the new voltage level. In another embodiment Fig. 3 (not shown) the voltage on capacitor 22 is transferred to a further capacitor (32) during the period t v , via an electronic switch and an impedance matching device. The capacitor 22 is then completely discharged before the arrival of the next input pulse.

Abstract: 1,066,568. Measuring fluid flow rate electrically. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 22, 1965 [Sept. 22, 1964], No. 40355/65. Heading G1N, A fluid flow meter comprises a flexible strip 1 (Fig. 1) which is deflectable by for example a flow of air perpendicular to its surface, whereby the resistances of strain gauges 3, 4 are caused to vary in proportion to the deflection and hence to the air velocity. The strain gauges may be connected in the arms of a bridge circuit Fig. 2 (not shown) and in operation the resulting unbalance output voltage is a measure of the fluid velocity. To increase the sensitivity of the strip, its portion which is exposed to the fluid stream is bent into a U-shape to make it more rigid, except in the region where the strain gauges are mounted, thus concentrating all the deflection upon this region. The strip may be provided with an oil filled damper 6.

Abstract: 1,194,867. Alarm clocks. GENERAL TIME CORP. Sept.5, 1967 [Nov.10, 1966], No.40486/67. Heading G3T. An electric alarm clock is characterized by the fact that the alarm is shut off by pressing down on the clock housing. At the time for sounding the alarm a cam 42 on an index wheel 40 aligns with a slot 43 in an hour wheel 18, thus allowing axial movement of the hour wheel towards the index wheel. An alarm control lever 30, pivoted in a notch 33 in a frame plate 14, is therefore rotated in a clockwise direction by a spring 34 and releases a blade 25 secured to a bracket 26. The alarm is therefore sounded as the blade is magnetically attracted to a pole 27 of a synchronous electric motor 15. The clock rests on a surface supported by its front edge and a rearwardly disposed button 51 attached to a lever 52 pivoted at 53. The front end 54 of the lever is coupled to a vertically movable slide 55 having a cam surface 62, so that on pressing down the top of the clock housing the lever 52 moves the slide 55 downwards. The cam surface 62 engages a cam surface 61 of the control lever 30 which is rotated into engagement with the blade 25 thereby stopping the sounding of the alarm.
