[A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 25, 1933.] [Class 7 (ii).] Combustion taking place in the chamber 2 drives pistons which compress air in the spaces 9 having inlet and outlet valves. The pistons are returned by the combined action of the pressure of residual air in the clearance spaces and by air compressed in buffer spaces 11 by extensions 13 on the pistons, the effective buffer surface being less than the area of the motor cylinder if the initial pressure in the air buffer is greater than .8 of an atmosphere, and otherwise greater, and the total energy imparted to the pistons for the return stroke being approximately constant. As shown, the buffer spaces open to the atmosphere at the end of the return stroke. Scavenging air is compressed on the inner sides of the extensions and delivered to a container 5 which subsequently delivers the air through slots 4 immediately after the combustion products have been discharged through slots 3. The scavenging spaces also supply air through pipes to complete the compressor air charge.

Title: A process for the polymerisation of olefines
IPC: C07C2/16
Filed: 1938-03-23
Abstract: 514,043. Polymerizing olefines. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 23, 1938, No.. 8946. Convention date, March 26, 1937. [Class 2 (iii)] Interpolymers of tertiary and secondary olefines are produced by emulsifying a liquid hydrocarbon mixture containing such olefines with sulphuric acid of about 55-80 per cent. concentration at about 120-70‹C. in a mixing apparatus, maintaining the reactants in emulsified contact until substantial interpolymerization takes place, removing the mixture from the reaction zone, returning part of it to the mixer before stratification occurs, and separating the remaining part into an acid layer which is also returned, and a polymer-containing hydrocarbon layer. The mixing apparatus may be a centrifugal pump in which the mixture circulates intensively or a packed tower with a jet mixer, e.g., of the venturi type, at the top. Two or more mixers may be used in series, the return of emulsion being preferably from the last to the first. The capacity may be increased by providing waiting tanks in which stratification is avoided. Tertiary olefines specified are isobutylene, tri- and tetra-methylethylene, and unsym. methyl ethyl ethylene, while secondary olefines are propylene, butene-1 and -2, pentene- 1 and -2, and 2-methyl-pentene-4. Mixtures containing paraffins and diolefines may be used. In particular, C4 fractions from cracking' petroleum are treated in liquid phase at about 20 atmos. with 63-72 per cent. acid at about 105-80‹C. Formation of SO 2 may be inhibited by addition of, e.g. 5-25 per cent. of phosphoric acid and/or phosphates to the sulphuric acid. The ratio of acid to butenes is 0.25-2.5, preferably 0.5-1.5 mols. of acid per mol. of butenes and the contact time 1-25, preferably 3-13 mins. Inert hydrocarbons such as paraffins, benzene, saturated carbocyclic compounds, gasoline or recycled unreacted gases may be added. Preferably the secondary olefines are in excess of the tertiary, for example 1.5-5 mols. secondary butenes per mol. isobutene. Specifications 479,940 and 514,081 are referred to. The Specification as open to inspection under Sect. 91 is not limited to a process involving return of the mixture before 'stratification and includes, as an alternative, the recycling of unreacted olefines recovered from the polymercontaining hydrocarbon layer. Any strong mineral acid may be used as catalyst, and phosphoric and benzene sulphonic acids are specified. This subject-matter does not appear in the Specification as accepted.

Abstract: 887,286. Brakes for web rolls. [WITTON-JAMES Ltd. March 15, 1960 [March 16, 1959], No. 9005/59. Class 103 (1). [Also in Group XVI] A web tension control arrangement for controlling the tension of a web unwound from a reel mounted on a spindle which rotates with the reel comprises fluid - operated control means responsive to changes in web tension, braking means for applying braking torque to the spindle, and brake actuating means responsive to the output of the control means to apply a braking torque dependent upon the output, the brake-actuating means being adjustable to operate in different ranges of braking torque for a given range of outputs from the control means. As shown, spindles and carrying reels 1, 2 and 3 are braked by brake blocks 28 arranged around the periphery of a disc 27. The blocks 28 are actuated by pistons 29, Fig. 2, within cylinders 30 supplied with air under pressure through selector valves 32, Fig. 1, thus the number of blocks operative to effect braking may be varied, e.g. to suit the width of web being unwound. The air pressure supplied to the cylinders is controlled by a web tension control roller 6 which operates a control valve 7 connected to a high pressure air supply. Alternatively, four pistons 29, Fig. 3 (not shown) may actuate a single brake block 28. In another embodiment, a brake drum, Fig. 4, is engaged by brake shoes 38 forced inwardly by inflatable tubes 39 connected to selector valves 32. In another embodiment brake shoes 48, 49, Fig. 5 (not shown), are actuated through a linkage 52, 53 or cam 62, Fig. 6 (not shown), by a chain or belt 44, Fig. 5 (not shown), engaging a central member 43 rocked by a piston within a cylinder 42 through a linkage 45 having adjustable pivot points along an arm. In a further embodiment, a cam 63, Fig. 7 (not shown), actuated by the piston of a cylinder 63 through a linkage 67 actuates a cam follower 64 which controls the braking action of shoes 65.

Title: Improvements in and relating to television systems
IPC: H04N5/073
Filed: 1936-03-26
Abstract: 456,564. Television; valve-generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London. March 26, 1936, No. 9087. Convention date, March 26, 1935. [Classes 40 (iii) and 40 (v)] In a method of television employing interlaced scanning, in which there are generated and transmitted line synchronizing signals of substantially constant frequency and wave form and frame synchronizing signals having initial portions of substantially the same shape and which are arranged to occur in substantially the same phase with respect to the line synchronizing impulses, each frame signal has a wave form different from that of the frame signal preceding it and succeeding it and from that of the line synchronizing signals. The line and frame signals are applied to an amplifier 9 and transmitter 12 to which the picture signals from the cathode-ray tube 1 are also fed. In addition, the signals are fed to valves 34, 39 and through an oscillation generator 13 to the line scanning coil 7. The frame signals, separated by the filter 41, 42, are fed to a blocking oscillator 15, the frequency of which is slightly below that of the frame frequency. The impulses provided by the valve 16 of the oscillator 15 are fed to the grid of a valve 27 in the plate circuit of which are a condenser 23 and resistance 24 producing the saw-tooth oscillations which are passed by a valve 38 to the frame coil 6. The frame signals are also applied by means of a resistance 33 in the cathode circuit of valve 34 so that in accordance with their form they vary the plate impedance of the valve 27 and thus change the level to which the condenser 23 discharges and the form of the saw-tooth oscillation, as indicated in Fig. 9, to produce interlaced scanning for successive pictures. In a modification, Fig. 7 (not shown), the valve corresponding to valve 27, Fig. 1, is connected to two blocking oscillators, of different frequencies. Alternate frame impulses only are fed to the oscillator of lower frequency so that the condenser in the output circuit of the valve is discharged to different levels. The blocking oscillators may be of the type described in Specification 402,629 and the synchronizing signals may be produced as described in Specification 407,409. Specification 448,065 also is referred to.
