Abstract: 972,627. Wrapping terminals. WESTERN ELECTRIC CO. Ltd. Oct. 8, 1963 [Oct. 15, 1962], No. 39547/63. Headings B3A and B3E. Apparatus for wrapping wire on a terminal comprises a bit member with a flat end surface, with a recess extending inwardly from the said end surface in order to receive the said elongated member, with a groove for receiving the strand, and with an arcuate slot tangent at one end to the said groove and tangent at the other end to said end surface, said arcuate slot being shaped to continuously engage the strand. Wire 51 to be wrapped on to a terminal 52 received in a recess 58 of a rotated wrapping bit 53 is guided from a longitudinal groove 62 in the bit 53 to the terminal 52 by an arcuate slot 66. The slot 66 is tangential at one end to a flat end face 57 of the bit 53 and at the other end to the groove 62. The slot 66 is also directed tangentially to the wall of the recess 58. In a modification, Fig. 14, to wrap various gauges of wire a recess 113 to accommodate the terminal to be wound is eccentric to the axis of the bit. A prior wrapping bit having a corner 29 and not an arcuate slot is shown in Fig. 12. Making the tool.-The arcuate slot 66 is formed in a bit blank 91, Fig. 9, by applying an abrasive compound, such as a diamond lapping compound, to advancing wire 51 and the longitudinal groove 62 at a point 154. Alternatively, an abrasive coating may be provided on the wire 51. The wire 51 while being wrapped on a terminal 52 upon rotation of the bit 53 forms the groove 66.

Title: Improvements in or relating to disc brakes
IPC: F16D65/092
Filed: 1957-12-23
Abstract: 854,685. Disc brakes. RECHERCHES ETUDES PRODUCTION R.E.P. Dec. 23, 1957 [July 9, 1957], No. 39953/57. Class 103 (1). In an hydraulic multipledisc brake having a plurality of brake discs 7, 8, lining carriers 10, 12, 15 provided with linings 9, 11, 13 and 14 arranged alternately with the discs, a non- rotatable clamping member 4 comprises a jaw 6 at one end to support one of the lining carriers 15 and a brake applying piston and cylinder arrangement 19, 5 is provided for applying pressure to the other lining carrier 10 to compress the linings and discs together, characterized in that the jaw of the clamping member is forked to facilitate machining of the cylinder and also by the fact that the lining carrier 15 which it supports has a projecting boss 15<SP>1</SP> which engages both arms of the fork. Lining carrier 10 is provided with a similar projecting boss 10<SP>1</SP> which engages the piston 19. Lining carriers 10, 12, 15 can slide with play longitudinally along guide pins 16 and 17. The piston and cylinder arrangement 19, 5 is provided with an automatic adjusting device to compensate for brake lining wear. The adjustment is such that the pressure of spring 29 together with the frictional force of fluid-tight packing 24 is less than the frictional force of the sealing members 21 and 22 associated with piston 19 which slides within jacket 23. When fluid under pressure is admitted into the cylinder, the jacket 23 and the piston 19 are first moved together towards the right, against the action of spring 29. When the bottom of the jacket comes into abutment against the shoulder 27 of rigidly fixed member 25 housed in the cavity 20 of the piston, it is arrested but the piston continues to move towards the right-hand side of Fig. 1 against the friction of the sealing rings 21 and 22 so as to apply the brake. When the hydraulic pressure is removed, the jacket 23 moves back under the action of the spring 29, and by virtue of the high friction due to the sealing rings 21 and 22, it brings back with it piston 19 over a distance equal to the initial distance between the bottom of the jacket 23 and the shoulder 27. This at length constitutes the constant play under which the brake operates, whatever may be the condition of wear of its brake linings.

Abstract: 1,236,860. Speech analysers. STANDARD TELEPHONES & CABLES Ltd. 13 Aug., 1969, No. 40557/69. Heading H4R. In a formant tracking speech analyser the speech waveform to be analysed is fed to the formant tracking circuit 2 via a band-pass circuit 1 whose frequency characteristic is controlled in accordance with the output of the formant tracking circuit to provide a hysteresis effect in the tracking, tending to make the circuit lock-on to a formant. As described the filter includes a band-pass filter 3 followed by a differentiating circuit 4 whose time constant is controlled by the output of a zero crossing spacing frequency detector. The differentiating circuit comprises a C.R. circuit in which the resistive branch is composed of the source drain paths of two FET's connected in series, Fig. 2 (not shown). The formant tracker frequency detector measures the interval between two zero crossings at the start of each pitch period, by detecting zero crossings in a detector 31, Fig. 4, and using the pulses so produced to trigger a monostable circuit 32 to produce constant length pulses which are fed to an integrator 33 to produce a voltage ramp commencing at the termination of each pulse. The voltage attained at the end of each interval is sampled and held in circuit 34. The measurement is limited to the first zero crossing interval in each pitch cycle as determined by the voicing cycle detector 35 comprising a full wave peak rectifier producing current pulses at the waveform peaks, with an inhibit circuit preventing peaks spaced by less than 3 m.sec. being detected.

Abstract: Chlorophyll-containing algae are rendered suitable for human consumption by exposing the algae, in the absence of carbon dioxide, to an intense white light until substantial bleaching of the algae has been effected.  In a preferred embodiment for preparing an algae nutriment, a concentrated culture of unicellular chlorophyll-containing algae is aged for from 72 to 96 hours in a liquid medium, after aging the pH of the culture is adjusted to 8.0-8.5, gaseous oxygen free of carbon dioxide is mixed with the culture and then bleaching is effected by exposing the culture whilst agitated by stirring or the admission of the gaseous oxygen or aeration devoid of carbon dioxide, to white light of intensity in excess of 2000 foot candles for between 2 and 24 hours duration.  The bleached algae are separated from the suspension by centrifugation and freeze-dried to give a fluffy white or light tan powder of bland flavour and odour which may be used directly as a food or food supplement.  The value as nutriment of algae of the variety Chlorella pyrenoidosa is discussed; it is stated that when a culture of this variety is grown in the presence of thiourea at a level approximately 10 per cent of the routinely used nitrogen source, urea, sufficient sulphur amino acids for daily consumption are provided by about 200 grams of the dry cell mass.
