Abstract: 1379260 Pneumatic conveyers BRITISH HYDROMECHANICS RESEARCH ASSOCIATION 24 Nov 1972 [26 Nov 1971] 54999/71 Heading B8A A conduit in a pneumatic shuttle conveyer is provided with a current boosting means comprising fluid energizing means to withdraw carrying fluid through a suction port and reintroduce the fluid after energization, through an injection port axially spaced from the suction port and convergently inclined to the axis of flow in the conduit. In the figure, air is withdrawn from conduit 10 through divergently inclined circumferential suction port 11, through suction manifold 13 and pipe-line 16 to an electrically driven fan 15. The air is then reintroduced through injection manifold 14 and convergently inclined circumferential injection port 12 to convey material in carrier vehicles in the direction of the arrow. Further embodiments, not shown, permit diversion of the load to a branch conduit by providing greater suction and/or less injection on the same side of the main conduit as the branch conduit, and less suction and/or more injection on the other side of the main conduit; and conveying of the load in either direction by the provision of an injection port on both sides of the suction port. More than one such current boosting means may be provided along the conduit.

Abstract: 632,557. Air-operated sanding tools. CENGAR UNIVERSAL TOOL CO., Ltd., and SUTCLIFFE, J. W. Jan. 8, 1948, No. 570. [Class 60] [Also in Group XXVI] An air-operated sanding tool for rubbing down or preparing the coachwork of automobiles and the like for painting and similar purposes, or for preparing wooden floors for polishing or for laying of rubber flooring, comprises a reciprocating piston to which the abrasive holder is secured, the piston having a pair of flats or recesses therein communicating with ducts opening in the ends of the piston, whereby the piston acts as its own distributing valve.

Abstract: 1449876 Remote control barrier operation SOC DE FABRICATION D INSTRUMENTS DE MESURE 13 Dec 1973 [22 Dec 1972] 57752/73 Heading E2M [Also in Divisions H3 and H5] A remote control operating mechanism for an access preventing barrier (e.g. for a car park entrance) comprises an electromagnetic radiation transmitter/receiver (Fig. 1) associated with means for moving the barrier and a mobile transponder (Fig. 2) which receives radiation from the transmitter 9, modulates it, then reflects it back to receiver 11; barrier operation being initiated on detection of a signal with correct modulation. The transponder has a parabolic reflector and two square wave oscillators 5, 6 of different frequencies; a diode 2 is non-conductive (thus allowing reflection) only when the signals from both oscillators are high simultaneously. The reflected signal is therefore turned on or off with a modulation that involves both frequencies. The receiver has filters that receive each frequency and an AND circuit which operates the barrier when both frequencies are present. The radiation is preferably of 1-10 cm wavelength e.g. 3 cm.

Title: Signal correlator for determining the modulus of an analogue signal
IPC: G01S13/26
Filed: 1970-12-10
Abstract: 1300287 Correlator radar PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Dec 1970 [13 Dec 1969] 58683/70 Heading H4D Although the claims generally relate to a correlator, the sole described application of such a correlator is for use in a correlation radar as shown in Fig. 1 which is substantially the same as that shown in Fig. 2 of Specification 1,167,668. The column number of that correlator CI xr  giving the maximum output R max  gives the speed of the target whilst the row number X gives the range. The correlator Cl 01 , thus, respectively replaces the operative group (A11, B11, S11, Q1, A<SP>1</SP> 11 , B<SP>1</SP> 11 , S<SP>1</SP> 11 , Q<SP>1</SP> 1 , T11, L11). In the prior arc correlator the orthogonal correlation component outputs p s , q s  of summers S 11  and S<SP>1</SP> 11  are squared and added by means Q<SP>1</SP>, Q<SP>1</SP> 1 , T<SP>11</SP> to give the modulus R of the correlation output. Such squaring operation is difficult, especially where digital processing is involved (A/D convertors, Fig. 1 yielding pulse width modulated signals). The present application thus proposes that the sum R p , Fig. 3 of the projections p s  Cos #, q s  Sin # of outputs p s , q s , on a plurality of different axes L, be determined and the target value of R p  so obtained be taken as sufficient approximation to R. In the embodiment of Fig. 2 in which Axr, B xr , A<SP>1</SP> xr , B<SP>1</SP> xr , O 1 , O 2  are equivalent to A 11 , B 11 , A<SP>1</SP> 11 , B 11 , S 11 , S<SP>1</SP> 11  in said prior art, four axes 4 1 , L 2 , 4 3 , L 4  are used angularly spaced by 45 degrees. The values of Sin # and Cos # are then such that the four projections are Rp 1  = p s , Rp 2  = (p s  + q s )/#2,R p 3  = q s , Rp 4  = (q s  - p s /)#2. That one of Rp 1  ... Rp 4  exceeding a threshold D, set in means Dr, is taken as representing R. As the signals p s  q s  are binary digital a forward/backward counter/integrator TL 1  ... TL 4  is included at the input to the analogue threshold means. To avoid multiplication factors involving 1/#2, combination logic C produced normalized valves C 1 ... C 4  of Rp 1  ... R 4  equal to:- p s , (p s +q s ) q s , (q s -p s ), and the corresponding thresholds in means Dr are adjusted to D, D#2, D, D#2. A disadvantage of the embodiment of Fig. 2 is that counter/integrator TL 2  and TL 4  have to count up to 2 times T4 and TL 3 . Therefore in the modification of Fig. 4 using parallel processing, combination logic C and counter/integrators TL 2  and TL 4  are such that normalized values (p s +q s )/2 and (q s -p s )/2 are used and the corresponding thresholds in Dr become D#2 and D#2. The embodiment of Fig. 6 (not shown) uses six axes nominally spaced by 30 degrees, but since this gives rise to difficult, multiplication factors of 1#3 actually spaced by angles such as 26 degrees 30 mins., 63 degrees 30 mins., having nearest integer multiplying factors.

Abstract: 741,395. Latex compositions. DUNLOP RUBBER CO., Ltd. July 1, 1954 [Aug. 1, 1953], No. 21403/53. Class 70. In a method of preparing a heat-sensitive natural or synethetic rubber latex mixture, i.e. one which is stable when cold but is gelled rapidly on heating, a stream of gelling agent and a stream of latex are mixed continuously in flow. The heat sensitive latex may be prepared in a mixing vessel and discharged continuously therefrom to be utilized for the manufacture of articles such as sheet or thread the latex mixture being shaped, e.g. by spreading or extrusion, gelled by heat, and vulcanized. In the manufacture for example of ebonite sheets for use as battery separators a stream of natural or synthetic rubber latex is mixed in a chamber with a 2 per cent solution of calcium formate as gelling agent the volume ratio of latex to gelling agent being about 3 : 1. The mixture is discharged continuously on to and spread by a blade on a travelling band consisting of canvas or other closely woven sheet and is then gelled in a heating chamber at about 80‹ C. The sheet carrying the gelled strip is then wound on a roller with woven fabric interlining and vulcanized by immersion in hot water or saturated steam. The ebonite sheet so produced is unwound from the roller, separated from the fabric interlining, trimmed, passed while hot between corrugated rollers to form strengthening ribs, and finally cut into pieces of the required size.
