Title: Improvements in and relating to brake or like operating mechanism
IPC: B60T11/04
Filed: 1928-02-28
Abstract: 312,592. Smith, W. H. Feb. 28, 1928. Hand, foot, and personal actuation. - Brakeoperating mechanism comprises a two-part handoperated lever, one part L being connected to the shaft S it is desired to operate which acts as a pivot for the lever as a whole and the other or handle part H being connected by a pivot P to the first part and provided with a spring pawl D engaging a fixed quadrant Q, the relative movement of the two parts being limited by pointed or rounded engaging members N, M. A part H<3> of the handle H engages a part L<3> of the lever L to ensure rigidity in applying the brake. To release the brake the handle H is moved to the left when it tilts about the pivot P and the point of the member N presses the plunger M down against a spring till the points pass and the pawl D is lifted clear of the rack. Further relative movement of the parts of the lever is restricted by the engagement of parts H<2> L<2>. The member N is adjustable. The lever may be locked in the " on " position by a key K, Fig. 2, adapted to be slid into a recess K<1> between the parts, a spring ball engaging a recess in the key-operating member. Another method of locking the lever comprises a spindle mounted transversely of the lever H and engaging the lever L. The spindle can be turned to bring a cut-away part opposite the lever L to allow it to move. Modifications are shown to suit various types of motor vehicles. In some a pivoted pawl is used, also an underracked quadrant may be used. In one modification, the quadrant. is secured to the handle H and the pawl is fixed. In another modification, a strap limits the movement, of the two parts of the lever. Fig. 14 shows a modified form suitable for railway-waggon brakes. The pawl D is pivoted on the pivot P and is connected by a spring A<1> to the member N which is pivoted at N<2> on to the handle H.

Patent GB-570358-A (GB)
Title: Manufacture of polymerisation products
IPC: C08F36/04
Filed: 1939-02-28
Abstract: Synthetic rubber is produced by polymerization of aqueous dispersions of one or more esters of 1-carboxy-butadiene-1-3 by means of heat or a polymerization catalyst which is an oxidizing agent.  Suitable esters are the methyl and butyl esters: they may be prepared as described in Specification 523,080.  Suitable catalysts are described in Specification 15271/14, [Class 2 (iii)].  A polymer of coarse grain may be made by vigorous stirring of the ester and water; a finer grain product such as a stable latex may be made by injecting a fine spray of ester into water which is vigorously stirred or shaken and which preferably contains a wetting agent such as an alkylnaphthalene sulphonate; other emulsifying agents that may be used are for instance inorganic esters of alcohols such as sodium cetyl sulphate, soaps, quaternary ammonium or phosphonium and ternary sulphonium salts of high molecular weight, aliphatic hydrocarbon radicles and also polymeric compounds forming viscous aqueous solutions such as gum tragacanth, soluble starch, methyl celluloses, polyvinyl alcohol, partly saponified polyvinyl esters, polyacrylic and polymethacrylic acids (preferably as alkali salts) and interpolymers of acrylic or methacrylic acid with other compounds such as an acrylic or methacrylic ester; also persalts such as ammonium persulphate, and hydrogen peroxide which are polymerization catalysts can also be used as emulsifying agents. Electrolytes of acid or alkaline nature may be added to the dispersions to be polymerized.  The polymerized dispersions may be used to form transparent films or coatings and when applied to fibres modify the feel and texture thereof.  In examples the methyl ester is polymerized in presence of sodium cetyl sulphate; hydrogen peroxide and sodium cetyl sulphate and the sodium salt of an interpolymer of methacrylic acid and methyl methacrylate; benzoyl peroxide and cetyl sodium sulphate; and cetyl trimethylammonium bromide and ammonium persulphate; the butyl ester is polymerized in presence of sodium cetyl sulphate; the ethyl ester is polymerized in the presence of cetyl sodium sulphate; the ethyl ester is polymerized in the presence of ammonium persulphate; and the methyl and ethyl esters are polymerized together in the presence of sodium oleate.

Title: High frequency sampler

Filed: 1964-02-18
Abstract: 1,030,102. Cathode-ray tube circuits. HEWLETT-PACKARD CO. Feb. 8, 1964 [Feb. 28, 1963], No. 6817/64. Heading H4T. In a circuit for producing a slowly-varying display signal from a number of amplitude samples taken at different instants along a rapidly recurring waveform, the signal to be sampled is supplied via resistors 15; 17 to a balanced tunnel diode circuit 9, 11 supplied with oppositely going ramp signals 43, 53 respectively from a generator 41. With no - input signal the ramp signals cause the tunnel diodes to switch operating states at the same time and the resulting signals when combined in resistors 19, 21 produce no signal at the input of amplifier 23. A signal at the input terminal having, for example, an instantaneous positive polarity will be combined with the two ramp signals so that the tunnel diode 11 will switch to its high voltage condition state earlier and the tunnel diode 9 will switch to its high voltage conduction state later than would occur in the absence of an input signal. Thus the duration of the pulse applied to the amplifier 23 is determined by the amplitude of the input signal the pulse being terminated by the change of state of tunnel diode 9. The output of the amplifier is supplied via a gate 25 and stretcher 27 to a utilization device 55, e.g. a cathode-ray tube, the gate being controlled by a time base generator 57 so that the reset cycle of the tunnel diodes does not affect the output signal. The stretcher 27 includes an integrating circuit converting the width modulated pulses to a corresponding amplitude modulated pulse. The output of the stretcher 27 is also supplied as negative feedback via resistors 29, 31 respectively, to the tunnel diodes. The tunnel diodes may be replaced by blocking oscillators or Schmitt trigger circuits.
