Title: Improvements in Non-Woven Fabrics and their Manufacture
Inventor: CROWTHER ERNEST HATFIELD
IPC: D04H13/00
Filed: 1966-02-19
Abstract: 1,172,865. Felt. FIBRELOCK FABRICS Ltd. 3 May, 1967 [19 Feb., 1966], No. 7382/66. Heading D1R. A method of manufacturing a fabric comprises preparing a substrate by needling retractile fibres into an open weave base fabric e.g. scrim, inserting primary fibres into the substrate and subjecting the composite fabric to treatment to effect shrinking, felting, retracting or compacting of the substrate. The primary fibres are preferably inserted by means of a needling process. The treatment to effect shrinking is preferably a milling operation but may be mechanical, physical or chemical, for example to effect crimping and curling of the fibres, or may be a treatment involving wetting, heating and friction. The retractile fibres may be wool, cotton, flax, hair or man-made fibres such as polyvinyl chloride or cellulosic fibres. The primary fibres are preferably chosen from the following: cashmere, camel hair, alpaca, llama, mohair, wool, cotton, flax, jute or any man-made e.g. polypropylene. The open-weave base fabric is preferably a cotton or nylon scrim.

Title: Capping of receptacles
IPC: B67B1/04
Filed: 1974-02-19
Abstract: 1424996 Stoppering bottles LEBOUCHAGE MECANIQUE 19 Feb 1974 [22 Feb 1973] 7425/74 Heading B8T [Also in Division G1] In a capping machine in which receptacles on a conveyer press a cap distributor followed by a pressing device, the distance between the conveyer and the cap distributor is adjusted to the height of each receptacle as determined by a device positioned upstream of the distributor. As shown, Fig. 1, bottles are passed in front of a photodetector system comprising a first detector 23 to sense the presence of a bottle and a pair of detectors 24, 25 which sense the height of the bottle and control a cam lifting device for the conveyer belt so that distributor 3 can place a cap on the neck of the bottle. The bottles then pass to a pressing device which forces the caps into the bottle necks. Heights h1 and h2 are the limits within which the distributor operates correctly so that if photocell 24 is exposed or photocell 25 covered the conveyer belt is raised or lowered respectively to bring the top of the bottle within the correct area. The variation in bottle height is very small and maximum adjustments of the order of 1 mm. are sufficient. In an alternative arrangement (Fig. 2) the photodetector system adjusts the height of the cap distributor above the conveyer belt.

Title: Digital frequency modulator
IPC: H03K3/72
Filed: 1970-03-19
Abstract: 1312481 Frequency shift signalling SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 19 March 1970 [12 May 1969] 7988/70 Heading H4P Frequency shift binary signals are derived from clock pulses which are divided to provide a number of further clock pulses all at different frequencies, one or more of these further clock pulses being combined with the original clock pulses positively ot negatively to form one or the other of a pair of waveforms which are divided to give the required frequency shift signals without phase or amplitude discontinuity. The selection of the further frequency(s) for combination is determined by input binary data signals and signals indicating the frequency channel. The original clock pulses are derived by subdivision from a fundamental clock signal which is then combined with the selected one of the pair before final frequency subdivision. In one embodiment, Fig. 4, clock pulses drive a 5-stage counter in a unit CB having tappings from various combinations of stages to four AND gates A4, to A7, which deliver the further clock pulses A to D. The original clock pulses are fed to an AND gate A1 and are divided by two at bi-stable B1. Control signals W, X, Y and Z, indicating whether the transmission is of data or supervisory signals (W), the transmission speed (X), the data to be transmitted (Y) and the supervisory signals to be transmitted (Z), select combinations of the further frequencies A to D, the combined signals appearing at AND gate A1 or OR gate O1 for addition to or subtraction from the signal from bi-stable B1, this signal being added to the original clock pulses at AND gate A8. The signal from AND gate A8 is divided at N100 AND N2 or N10 to provide the required frequency shift signal.
