Abstract: 1528464 Panelling V G S GmbH 23 Oct 1975 [23 Oct 1974 (2) 15 Nov 1974] 43522/75 Heading E1W Elements of panelling, windows, screens etc., are secured together by multiple plastics clips of the form shown in Fig. 1. Axial slots 2 at each end of the clip grip the securing flange 3 of a cover strip or trim 4 or 4'. In addition, shoulders 6, 8 may be used to grip parts of panelling etc. Thus, as shown in Fig. 2, an abutment 10 may hold a window or screen 12, or a U-shaped plastics section 15 may extend over the whole length of the clip and serve to secure a screen 12 between seals 18, 19 (see also Figs. 3, 4 and 5, not shown, in which some only of the shoulders 6, 8 are used). As shown in Fig. 6, the U-shaped section 28 may be secured to a batten or post 30 (or to an intermediate panel 27, Fig. 7, not shown) between two panels 26. Such battens may be secured together or to the added sections to provide angled screens (Figs. 8 and 10, not shown), or a special angled support 31 may be provided for this purpose as shown in Fig. 9, so that T, L or X-shaped structures may be made.

Abstract: 1,223,571. 1,1<SP>1</SP>-Peroxycyclohexylamine compositions. BP CHEMICALS (UK) Ltd. 5 Nov., 1969 [13 Sept., 1968], No. 43572/68. Heading C2C. The invention comprises a liquid mixture of 1,1<SP>1</SP>- peroxydicyclohexylamine, cyclohexanone and a liquid hydrocarbon. Suitable hydrocarbons are, for example, toluene, xylene, cycloalkanes and alkams, such as those contained in light petroleum fractions, boiling in the range 100-160‹ C. The hydrocarbon stabilizes the mixture of 1,1<SP>1</SP>-peroxydicyclohexylamine and cyclohexanone, such as is obtained by the reaction of cyclohexanone, hydrogen peroxide and ammonia. The hydrocarbon is preferably present in the stabilized mixture in a concentration of 5-50% by weight. The hydrocarbon may be removed, when required, from the mixture by distillation under reduced pressure.

Title: Improvements in and relating to double twist spindles
Inventor: MELDRUM JOHN IRVING
IPC: D01H13/10
Filed: 1959-12-23
Abstract: 966,518. Tension control devices. COURTAULDS Ltd. Dec. 22, 1960 [Dec. 23, 1959], No. 43648/59. Heading D1D. Apparatus for controlling tension in a thread withdrawn from a two-for-one twister employing a stationary reel comprises two braked guides 7, 30 drivable together in rotation about the axis of the reel by a thread engaged with the guides and being withdrawn from the reel, the braking of the guides being variable in response to changes in the tension of the thread to maintain the tension at or near a predetermined value. The reel is mounted on a tapered shaft 1 and the thread 35 passes over a bowed guide 7, across a bowed guard plate 8, around a guide wheel 30, over wheels 32, 33 and into the bore 12 of the shaft 1. A cage 2 is rotated relatively to the shaft 1 by the thread 35. A flexible metal strip 13 is wound around a stationary carbon block mounted on the shaft 1 and exerts a braking action as the rotation of the cage 2. If the tension is greater than the predetermined value the thread causes the wheel 30 to move against the action of a tension spring 27 towards the guide 7, the spring 27 being connected between a lug 25 on an arm 22 extending from an independently rotatable annulus 21, Fig. 3, and a pillar 28 on the surface 9 of the cage 2. The rotation of the annulus 21 reduces the tension in a weaker spring 17 connected between an arm 20 on the annulus and a quadrant 15 which pivots to loosen the strip 13 to decrease its braking action on the block 10. Similarly when the tension is too low the strip 13 is drawn more tightly on the block 10. Instead of a friction brake a magnetic brake may be employed.

Title: Analogue-to-digital converter
IPC: H03M1/00
Filed: 1974-10-11
Abstract: 1481460 Analogue-to-digital conversion; pulse modulation circuits ITT INDUSTRIES Inc 11 Oct 1974 [12 Oct 1973] 44075/74 Headings H3H and H4L In analogue-to-digital conversion, the difference VE between the analogue input signal VX and a feedback signal VM controls the duration of pulses IM which are passed through a filter FL to derive VM, and the duration of the pulses IM is digitized by counting clock pulses IB. As shown, counter CT is continuously incremented by clock pulses IB and delivers overflow pulses IR to trigger pulse duration circuit TP. CT is read out at the end of each, or every tenth, IM pulse, into a register MM, delivering the required digital signal STN. In a modification, Fig. 2 (not shown), a counter CT is used only to supply trigger pulses to TP, a second counter (CM) counting clock pulses for the duration of IM. If Vx can take positive and negative values, a sign bit (SG) is derived from the error signal (VE), the polarity of the fed back signal (VM) being appropriately controlled, Fig. 3 (not shown). Fig. 4 shows details of pulse duration circuit TP: whenever a pulse is received at EIR a pulse is produced at SIM of duration dependent on the voltage at EVE.

Title: System for Transmitting or Recording and Reproducing a Plurality of Signals
IPC: H04N5/92
Filed: 1966-10-03
Abstract: 1,168,076. Television; multiplex pulse systems. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 3 Oct., 1966 [7 Oct., 1965; 18 Jan., 1966 (2); 15 Feb., 1966 (3); 25 Aug., 1966], No. 44095/66. Headings H4F and H4L. Relates to a modulation and demodulation system for modulating two signals in one channel, e.g. the I and Q chrominance components in an N.T.S.C. or PAL type colour television signal or the alternating colour difference chrominance components in a line sequential colour television system, and to the use thereof in recording a composite colour television signal on a magnetic tape to avoid the beat which otherwise occurs between the colour subcarrier and the frequency modulated carrier of the magnetic recorder. The modulation system comprises a transistor astable multivibrator, Fig. 7, in which the ON-OFF points of the two transistors are controlled separately and alternately by the two modulation signals a and b. Assuming the ON-OFF points x 1  y 1 , x 2 , y 2 ... of the modulator vary linearly corresponding to the levels of modulation signals, Fig. 8 (i), a modulated wave as shown in Fig. 8 (ii) is produced with the informations a and b occuring alternately between the zero cross-over points. To demodulate the signal of Fig. 8 (ii), it is differentiated, Fig. 8 (iii) and used to trigger a mono-stable multivibrator to produce an output, Fig. 8 (iv) which is added (or otherwise matrixed) with signal, Fig. 8 (ii) and passed through a low band-pass filter to give signal b (or a). Two embodiments of the demodulator are described with reference to Figs. 9-14 (not shown). The modulation system may be used to modulate the two chrominance components, e.g. I and Q, or R and B which are to be recorded in one channel of a magnetic tape recorder, the luminance or G signal being frequency modulated on a carrier and recorded in a second channel of the recorder. If a onechannel magnetic recording apparatus is used, the luminance (including the horizontal synchronizing signals) and chrominance signals thus modulated are sequentially switched at line frequency to the magnetic recording head (or heads) the reproduced signals being alternately delayed to produce a continuous colour television signal.
