Abstract: 1396188 Leather-fibre material; sheet-forming apparatus; finishing fabrics K OCKHARDT 6 Dec 1972 [7 Dec 1971 24 Nov 1972] 56258/72 Headings D1S, D2A and D2B [Also in Division B2]  A method of making leather fibre material suitable for use as a shoe lining comprises forming a web by dewatering an aqueous slurry of waste leather fibres of a leather which has been tanned with mineral and/or vegetable materials and other fibres having a length from 3-40 mm, the solids content of the slurry being from 0.1-0.5 g/litre, drying the web, impregnating the dried web with an elastomeric binder, and finishing the resultant impregnated web. The other fibres may be fibres of synthetic materials, viscose, waste textile materials, asbestos, or glass. Specified synthetic materials are polyamides, polyesters, polypropylene, and polyacrylonitrile. The aqueous slurry may contain thickeners, e.g. methyl cellulose, friction reducing agents e.g. a polysaccharide and may have its pH adjusted to a value from 4 to 7 by the addition of a mineral acid or alluminium sulphate. The elastomeric binder may be a natural or synthetic rubber, e.g. neoprene, a fluorocarbon elastomer, a polyacrylate, silicone rubber, polysulphide rubber, polyvinylchloride latex or butadiene-acrylonitrile copolymer. To increase flexibility, the web may also be impregnated with bone oil, glycerine, or other polyol. The impregnated web may be finished by having its surface ground and pressed to provide a smooth surface. Sheet-forming and Finishing Apparatus. The web comprising leather fibre material may be made on a conventional wet sheet-forming machine comprising a climbing screen and suction boxes (Fig 1, not shown). The head box may be provided with a sintered plate through which air is diffused into the slurry therein (Figs 2, 2a, not shown). An intermediate layer G of a woven or non-woven fabric may be incorporated between two wet webs of the material see Fig 3. In a modification, see Fig 4, the layer G is incorporated in the web by passage over a 'guide plate in the headbox and through the slice of the headbox. The impregnated web may be finished by passage between a press roll and a cooled drum, the surface of which is covered with a grinding belt, (Figs 5, 6 not shown). Alternatively, the impregnated web may be moistened and smoothed by passage between a pressure felt cloth and heated drum, (Fig 7, not shown). Smoothing of the impregnated web may also be effected by contact heating and compaction between two plates, (Figs 8-11, not shown).

Title: System for deriving television signals from holographic and nonholographic records
IPC: H04N5/76
Filed: 1970-11-30
Abstract: 1338387 Television K VOCKENHUBER and R HAUSER 30 Nov 1970 [28 Nov 1969] 56673/70 Heading H4F [Also in Division G2] Television signals are produced from a holographic record (a monochromatic and preferably coherent light source being used) or from a non- holographic (e.g. photochemical) record by selectively or simultaneously (e.g. for fading) projecting images thereof on to the light-sensitive surface of a television camera. The two records are preferably cinematographic records. In a first embodiment, Fig. 1, a plastics film 2 having a relief-like phase hologram embossed thereon is moved through a film gate 3 and illuminated by a laser diode 4, the resulting virtual image 6 being focused on to television camera 9 by lens 7. Since it is a hologram, intermittent film transport is not necessary. A standard cine film 11 may also be projected on to the camera 9, the film being intermittently  moved past a revolving shutter 13 and illuminated by lamp 14, and lens 15 producing an image in the plane of the virtual image 6. The image 6 derived from the hologram although monochromatic preferably contains coded colour information the recording having been made using two primary colour line screens of different frequency, a luminance signal and the two primary colour signals on respective carriers being derived from the camera output with the aid of filters (Figs. 3-5, not shown). If cine film 11 is a colour film then corresponding colour coding line screens 19 and 20 are included in the light path as shown. Alternatively the cine film 11 may be colour encoded during exposure thereof, a monochrome film being used (Fig. 6, not shown), in which case screens 19 and 20 are omitted. In a second embodiment Fig. 2, the holographic film is illuminated by a helium-neon gas laser 35, and the resulting image and/or an image from cine film 11 illuminated by lamp 14 is projected on to camera 9 via a partially transmitting mirror 37. Continuous transport of film 11 is employed, image shift being compensated by a rotating glass prism 40 and the film transport being synchronized with the camera scanning by means of a photoelectric perforation detection system 42-48. Instead of mirror 37 a hinged mirror 50 may be used to project the cine film 11 on to the camera, this mirror being fully or partially transmissive. The hologram film may be illuminated by a normal incandescent lamp or a gas discharged lamp, the light therefrom being directed via a slit and band-pass filter preferably short wavelength to produce the required coherence and monochromacity. The same lamp may thus be used for both films. When laser diodes or solid lasers are employed they are preferably pulsed.

Abstract: 1,215,150. Firing explosive charges. POUDRERIES REUNIES DE BELGIQUE SOC. ANON. 14 Dec., 1967 [1 Feb., 1967], No. 56886/67. Heading F3A A method of establishing a pyrotechnic chain under the effect of a number of pulses comprises advancing a first member or group of members from a rest position in which the pyrotechnic chain is not established to a final work position where the chain is established, each step being executed in response to one of said pulses, and by means of a second member or group of members bringing said first member or group of members back to its rest position when the time interval between one of the pulses and an immediately succeeding pulse is greater than a predetermined time interval or allowing it to advance further to the final work position when the time interval between a pulse and an immediately succeeding pulse is less than the predetermined time interval. The advancing movement may be angular, rectilinear or mixed movement. A preferred apparatus for carrying out the method comprises an anti-tank mine fuze comprising a striker 33 held against the bias of a spring 37 by a pin 34 lying across slots 5 and 6 in a disc 1 provided with teeth 2 and 3 and a ratchet wheel 7; a second disc 8 having a tooth 9, a ratchet wheel 13, an extension 32 for simultaneously rotating a primer carrier 28, a hub 10 co-operating with an escapement mechanism 12; a stop 21 biased by a spring 23 about an axis 22; and a push rod 18 connected mechanically, electrically, magnetically, hydraulically &c. to a drive sensitive to pulses, e.g. the head of a mine. In operation, at each pulse, the push simultaneously shifts the ratchet wheels and their associated discs clockwise whereby the extension 32 brings the primer 27 into line with the striker pin, and the slots 5 and 6 in the disc 1 are moved step by step into line with the pin 34 to free the striker, provided the time interval between one of the pulses and the immediately succeeding pulse is less than the time interval set by the device 12 for the return of the disc 8to its initial position under the action of spring 15. During the arming movement of the disc 1, the disc is prevented from reverse movement to its initial position, under the action of spring 14, by engagement of the stop 21 with the teeth 2 or 3, until disc 8 returns to its initial position and lifts the stop clear of the teeth. The firing pin and primer can be replaced by an electric contact, a piezoelectric system or a magnet and moving core device. In another embodiment (Figs. 6-13, not shown) various elements in the fuze are replaced by mechanically equivalent elements.

Abstract: 1,191,353. Forming insulating sleeves by winding. NEDERLANDSE STEENWOLFABRIEK N.V. 18 Dec., 1967 [29 Dec., 1966], No. 57309/67. Heading B8G. [Also in Division F2] A mat 2 of mineral wool fibres containing a binding agent, is wound on to a rotatable apertured mandril 1 whilst being pressed thereagainst by an endless belt 6; when the desired thickness has been wound on to the mandril 1 the supply of matting 2 is terminated and fluid is passed through the apertured mandril 1 and/ or upon the outside of the mat in such a way that the binding agent hardens. The endless belt 6 passes over pulleys 8, 10, 11, 12, 13 and as the diameter of the winding on the mandril 1 increases the pulley 11 is caused to rise. The support for the pulley 11 eventually engages a contact 15 to excite a relay to cause a non-rotatable cylindrical member 16 to descend and cause the matting to tear apart below the member 16.

Title: Improvements in or relating to motion damping devices
Inventor: LACEY ALBERT FREDERICK
IPC: F16F15/121
Filed: 1966-12-30
Abstract: 1,207,805. Vibration dampers; springs. SMITHS INDUSTRIES Ltd. 22 Dec., 1967 [30 Dec., 1966], No. 58261/66. Heading F2S. The rotary movement of a stepping motor, e.g. in a vehicle odometer, is damped by a spring 4 of the form shown which engages a rotating part 1 such as a brake drum attached to the motor's shaft. On starting the motor, static friction causes the spring's central portion 5 to move with the part 1 until slipping occurs, after which further movement is damped by dynamic friction. During the static friction phase the spring is deformed and on stopping the spring relaxes toward the undeformed state shown. This tends to prevent final stoppage at a position of zero torque; moreover (in contrast to the effect of a purely frictional damper) starting from a position of near-zero torque is not prevented.
