Abstract: 333,946. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 25, 1929. Chloro- and bromoacetylenes and derivatives thereof are produced by the direct replacement of hydrogen combined with triply linked carbon atoms by means of chlorine or bromine by subjecting the acetylene compound to the action of an aqueous solution of a salt of hypochlorous or hypobromous acid, advantageously with the addition of an excess of free alkali. Examples are given of the preparation of dichloro-acetylene, dichlorodiacetylene, dibromo-acetylene, dibromodiacetylene, bromo- and chloro-propiolic acid, 1- bromoacetinyl-cycloliexanol-1, and diethylbromoacetinyl carbinol.

Abstract: A method of producing a wrapped tobacco-smoke filter comprises mixing powdered or granular tobacco-smoke filter material with powdered or granular thermoplastic material, feeding the mixture from a hopper on to a paper band and heating the mixture to cause the particles of the filter material to become bonded by the thermoplastic material.  The bonding material may comprise polyethylene, polypropylene, polystyrene or a polyethylene co-polymer with a vinyl or acrylyl ester.  The filter material may be charcoal, silica gel, zeolites, perlite, sepeolite, activated alumina, magnesium silicate or mixtures thereof.  The mixed filter material and bonding material are heated and shaped by dyes to cause bonding and then are passed through one or more cooling dyes.

Abstract: 967,743. Valves. GENERAL PRECISION Inc. May 5, 1961 [May 12, 1960], No. 16445/61. Heading F2V. A valve includes a housing having a chamber 34, a valve member 40 of thin cross-section and low mass extending across the chamber and dependent for its function upon the position of a control member 42, a port 45 traversing the valve member 40, resilient means 60 acting on the control member to urge a pilot valve 50 into engagement with a seat in the port 45, and means 17 in the housing to move the control member 42 against the means 60 and open the pilot valve 50. When the electromagnet 17 is energized, the member 42 and the pilot valve 50 to which it is secured are lifted against the spring 60 so that fluid may flow to an outlet port 15 through a passageway 47 in the valve member 40 to produce a pressure differential which lifts the latter from its seat 38. When the valve is closed the fluid pressure assists the action of the spring 60. The valve member 40 is made of a non-magnetic material, such as an aluminium-bronze alloy, and the chamber 34 is which it is housed is sealed from the electromagnet 17 by a seal 30 of rubber-like material. A threaded connection 18, 19 between the electromagnet 17 and the valve housing permits the polepiece 20 and hence the lift of the valve to be adjusted.

Mirror 108 has its spherical centre located at point 110 in correction lens 74 by a procedure described w.r.t. the optical bench of Fig. 16 (not shown) and w.r.t. Figs. 17 and 18 (not shown), it has three trapezoidal shaped radially extending lugs (116) (Figs. 8 and 11, not shown) receiving resilient bifurcated portions of extensions (118) integral with plates (98) for lateral location and which permit surface 108 to rest against edge 120 defined by conical chamfer (122) (Fig. 13, not shown).

Title: Static frequency converter with voltage control
IPC: H02M5/27
Filed: 1968-04-08
Abstract: 1,222,292. Frequency converters. WESTING- HOUSE ELECTRIC CORP. 8 April, 1968 [21 April, 1967], No. 16726/68. Heading H2F. The frequency converting apparatus described is substantially as described in Specification 1,222,291 but the claims are directed to a feature in which a common control means varies concurrently the switching ON and turning OFF times of each switching unit during each repetitive switching pattern, whereby the output voltage E F  is made to vary linearly with the output frequency # o . Thus the ratio of the conduction angle t 1  (see Specification 1,222,291) to the time frame T (i.e. t 1 /T) is made linearly variable with output frequency f 0 , in order to vary the output voltage E F  substantially linearly with f 0 , so that E F  increases as f 0  is increased and a constant volts/cycle is maintained. As shown Fig. 12, an oscillator 102 supplies a sawtooth waveform to one input of a comparator 106 whose other input via a line 107, is a reference voltage which is proportional to the frequency of the pulse train P 0  and is obtained from a potentiometer 72<SP>1</SP>. The wiper of 72<SP>1</SP> is ganged to the wiper of a potentiometer 63<SP>1</SP> which provides a variable voltage reference source, the output of which is connected to the oscillator 102. The oscillator output frequency is linearly variable in response to input voltage from the source 63<SP>1</SP>. The comparator produces a pulse P 2  each time the sawtooth intercepts the reference voltage on line 107. Common operation of the wipers 108, 110 thus provides constant volts/cycle output when used to generate the pulses P 0 , P 2  in the system of Fig. 7. The circuit of Fig. 12 is the alternative to the part of the circuit in box Q of Fig. 7 (i.e. the clock generator and time delay D 3 ). Fig. 13, not shown, illustrates the comparator waveforms and Fig. 14 (not shown), gives circuit details of the oscillator and comparator.

Abstract: 1,130,854. Salt of low bulk density. CEREBOS FOODS Ltd. 13 April, 1966 [22 April, 1965], No. 17054/65. Heading C1A. Low bulk-density common salt is prepared by forming an aqueous foam carrying common salt in suspension from a liquid containing a brine-soluble wetting agent, the foam formed being either dried and subdivided or moulded and dried to give the product in particulate or coherent (e.g. " cut-lump ") forms respectively. The wetting agent may be a cationic surface-active agent (e.g. dodecyltrimethylammonium bromide) or an anionic surfaceactive agent (e.g. sodium lauryl sulphate). A foam stabilizer (e.g. gelatin) and a humectant (e.g. MgCl 2 ) may be added to the liquid from which the foam is prepared, the humectant alternatively being sprayed in solution on to the dried product. In this process the bulk density is reduced from an initial value of 1.0 gm./c.c. down to 0.6 gm./c.c. or less for the product which thus compares with open-pan salt. Reference is made to Specification 1,016,743 for the foaming technique and to Specification 1,016,742 for the use of humectant.
