Title: Production of pilesurfaced products
IPC: B29C67/00
Filed: 1970-11-20
Abstract: 1378638 Pile fabrics IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Nov 1971 [20 Nov 1970 (2) 24 Dec 1970 (2)] 55241/70 55242/70 61325/70 and 61326/70 Heading B2E [Also in Division Dl] A pile fabric is made by interposing a heat softenable composition 2 between a foundation layer 1 and a heated roller 3, holding the composition 2 against the layer 1 so that they bond together and the composition adheres to the roller 3, parting the layer 1 and composition 2 from the roller 3 so that filaments are drawn from the composition and hardening the filaments by means of a cooling fluid 5. The composition 2 may be coloured or patterned by using a printed monolayer of film or by using an appropriately coloured multilayer film. The composition may be preheated or supplied from an extruder rather than as a film (Figure 2, not shown) or it may be supplied in powder or granule form, in the form of a woven fabric or in a cellular or foamed form. The foundation layer 1 and composition 2 may be held against the heated roller 3 by a roll 4 or by resilient means, i.e. a resilient coated roller or the foundation layer: 1 itself may form the resilient means. The cooling of the filaments may be varied across the width of the fabric to affect the curliness of the filaments or to provide filaments of differing heights. The cooling may be on either side of the pile fabric. To produce areas of the fabric with patterned effect, e.g. no filaments, areas of the heated roller may be rendered non-adhesive, embossed so that the composition does not contact-these areas or a stencil may be interposed between the composition and the heated roller. To facilitate parting of the composition from the heated roller a cooled rod 9 may be provided (Fig. 4). The composition may be pressed through a porous or perforated web, which may be the foundation layer, into contact with the heated roller.

Abstract: 1421788 Photo-electric analysis apparatus HEWLETT-PACKARD CO 4 Dec 1972 [6 Dec 1971]  55863 Heading G1A In a two beam analysis apparatus including scanning mono-chromators 12, 38 a beam-splitter 21, and reference and sample path photo-cells 24, 25, the reference path output is stored and compared with the sample path output so as to derive a ratio of the two outputs.  The source 37 may emit the same spectrum as the source 11, so as to increase the photo-cell outputs. Or it may emit in a different wavelength region. The sources are operated simultaneously, so as to monitor the sample transmissivity properties over a broad spectral range. In the embodiment of Fig. 5 the two light sources, which emit in different wavelength regions, operate simaltaneously, as do the two acoustooptic mono-chromators 12, 38. The scanning RF signals W 1  W 2  applied to the respective monochromators are modulated at different frequencies W 3 , W4. The detector outputs are de-multiplexed at 45-48 and the signals corresponding to the different light sources are directed to the appropriate divide and memory circuits. A detailed description of prior art apparatus is given, Figs. 1-3 (not shown).

Abstract: 1279600 Differential steering CLARK EQUIPMENT CO 15 Dec 1970 [26 Jan 1970] 60388/70 Heading B7H [Also in Division F2] In a steering assembly two handles 32, 34 independently control the direction and speed of respective drives at each lateral side of the vehicle, and means are provided to bias the two handles into a position in which the respective drives have the same direction and speed. Hydrostatic transmissions 46, 48 include swash plate pumps 50, 78 having variable output and direction of rotation. Either of the handles 32, 34 is pushed forward for the vehicle to proceed in a straight line since both handles will be displaced the same amount due to the action of the mechanism 126 and so the swash plate pumps drive the respective wheels at the same direction and speed. To change the heading of the vehicle either handle is moved relative to the other and on release the handles are restored to identical positions by means of tension springs 144, 146, Fig. 4, acting through pins 140, 142 slidably mounted in converging slots in the plates 128, 130. The plates are fixed to respective coaxial shafts 106, 112 of the handles 32, 34. The amount of differential movement of the plates 128, 130 is restricted by means of a tube 174, Fig. 7, fixed to the rod 142 having extending therethrough a bolt 176 fixed to rod 140 with distance nuts 178. The swash plates 86, 58 are biased to their zero dipslacement position by means of a V-shaped cam 162 biased for engagement with rollers 158, 160 on each plate 128, 130 so that the rollers are urged to an apex of the cam.

Patent GB-697928-A (GB)
Abstract: 697,928. Calculating-apparatus. AKTIE-BOLAGET ORIGINAL-ODHNER. May 25, 1951 [June 6, 1950], No. 12347/51. Class 106 (i). An adding or like machine adapted for performing calculations in non-uniform systems, such as English currency, and with means for locking the non- decimal denominations of the totalizer, is characterised by the provision of a " blocking key " which, when operated, locks the non-decimal denominations of the totalizer and the corresponding printing members in such a position that no printing is effected, and also a " zero key which, when operated, looks the non-decimal denominations, but during the machine cycle causes zeros to be printed in the non-decimal columns ; in both cases a known step stopper is displaced a number of steps corresponding with the number of non-decimal columns so that the item set by the numeral keys is entered into the correct decimal denominations. Depression of the blocking key 2 rocks a lever 5 and, through linkwork 6, 7, 8 a locking member 9 is brought into the position shown, blocking any movement of the calculating and printing racks 13. Depression of the zero key 3 would operate a linkage 14, 24, 25 to rock a lever 15 and transmit movement through the linkwork 6, 7, 8 as before, but in this case a stop 26 co-operating with the bell-crank lever 14 limits the extent of movement so that the racks 13 are blocked by a step 11 after a limited movement which sets the racks for printing zeros. Either of the keys 2, 3 by operating the lever 15 releases a spring-urged slide 17 with shift stop 18 to move up to a stop 27, a distance corresponding to three steps of the step-shifting mechanism. Thus the actuator, with the item set thereon, is moved a distance corresponding to the lowest three denominations whereby the lowest digit of the item is entered in the fourth column from the right. A cam 21 and lever 20 restores the slide 17 to its initial position at the end of each machine cycle.
