Inventor: HAM ARTHUR FREDERICK
IPC: A41H1/02
Filed: 1962-09-19
Abstract: 974,259. Headwear measuring devices. BRITISH HAT & ALLIED FELTMAKERS RESEARCH ASSOCIATION. Sept. 19, 1963 [Sept. 19, 1962], No. 35593/62. Heading A3V. A headwear measuring device comprises a circular spring attached to an arm which moves adjacent an arcuate scale. A hat is placed over a circular spring 23 and rests on flats 22 attached to a cap 21 on a peg 13. To position the hat the spring is initially compressed by rotating the channel arm 14 on the pivot. The spring is connected to the cap 21 and to a drum 17 on the pivot the drum being connected to the arm 14. An arm 18 on the peg 13 is adjusted by varying the tension in a spring 20 connecting the arms 14 and 18 until an arrow on the arm 14 coincides with a window 19 in the arm 18, the hat size is then read off an arcuate scale 11 on a base 10. The spring 20 is initially tensioned by pinning a tab 16 on the arm 14 to a hole 12 in the base, then standing the base on the edge 30 and adjusting a bolt on which the spring 20 is coiled until the arrow is visible in the window. To minimise error due to friction between the spring 23 and the leather hat band, the arm 14 has a line 31 thereon which is aligned with one of two adjacent arrows 32, 33 on the arm 18 before aligning with the second which gives the correct measurement on a scale above the arms.
Patent GB-1114899-A (GB)
Title: Spinning glass filaments
IPC: C03B37/04
Filed: 1965-08-19
Abstract: A process for the production of glass filaments comprises projecting small streams of molten glass horizontally, directing a gaseous blast downwardly against the glass streams to thereby attenuate them to form filaments and spraying water on the attenuated filaments at a first zone and liquid binder resin at a second zone below the first. Molten glass (G) is fed through a quill shaft 6 to a centrifuge spinner 5.  The glass passes through a perforated distributer 7 <PICT:1114899/C1/1> to the interior of the spinner 5 from whence it is projected horizontally through orifices in the peripheral wall thereof.  A downwardly directed gaseous blast from an annular orifice 10 in the floor of a combustion chamber 9 attenuates the horizontally directed glass streams in a downward direction.  Nozzles 14, located round a ring 13 positioned adjacent but immediately below the spinner 5 and of a diameter greater than annular orifice 10, spray cooling water W on to the attenuating filaments in a direction transverse to their direction of attenuation. Nozzles 15 on a further ring 16 located below the ring 13 downwardly spray the binder R on to the glass filaments which are then collected as a mat (B) on a conveyer (11).  The rings 13, 16 are mounted for vertical adjustment.

Title: Improved Patterning Mechanism for Circular Knitting Machines
Inventor: FARMER ERNEST LEONARD
IPC: D04B15/66
Filed: 1967-08-04
Abstract: 1,167,418. Knitting machines. WILDT MELLOR BROMLEY Ltd. 29 July, 1968 [4 Aug., 1967], No. 35804/67. Heading D1C. [Also in Division G3] The selector mechanism for actuating the jacks of a circular stationary cylinder machine as described in Specification 1,145,394 is controlled by solenoids S Which influence latches 26 controlling the position of programming levers 23 the operative ones of which actuate the presser slides 18 of the selector mechanism. The solenoids S are energised according to the dictates of a punched film or band which is read photoelectrically by a series of photoelectric cells 29 which transmit the information recorded by the presence or absence of punched holes in the film to thyristors which store the information received. Operated in conjunction with the rotation of the machine parts is a reed switch RS which is incorporated in the circuit of an electronic timer T. The reed switch RS is actuated at intervals in relationship to the machine speed to charge a capacitor C of the electronic timer T and to subsequently permit its discharge into a transistor TR thereby generating a power pulse which fires or triggers the previously opened thyristors 29 which thereupon energise the corresponding solenoids. Consequently the punched film can be advanced and the information received by the thyristors prior to it being used, the stored information then being imparted to the machine only when the reed switch, which is operated in timed relationship with the machine, activates the timer to permit the thyristors to effect energisation of the solenoids. All of the levers 23 are initially moved to an operative position in which their noses 23b are projected into a path in which they would engage a tail 19c of a lever 19 controlling the presser slides 18. For this purpose a roller 52 on the end of a slide 51 carrying a cam follower 50 serves to engage a beater bar 41 and to move the levers 23 accordingly. Likewise a beater bar 53 operated by a cam actuated lever 60 moves all of the latches 26 into an inoperative position. Subsequently on energisation of the respective solenoids according to the programme dictates of the punched film, the selected solenoids move the corresponding latches 26 into an operative position in which they engage the arms 23c of the corresponding levers 23 to prevent their return to an inoperative position and consequently they remain operative with their noses 23b projected.

Abstract: 349,630. Loud-speakers; receivers. POLIAKOFF, J., 14, Sutcliffe Close, Golders Green, London. Dec. 3, 1929, No. 37050. [Class 40 (iv).] A loud-speaker or other telephone receiver has a diaphragm, cone or other vibrating member actuated by electromagnetic and electrostatic means simultaneously, the diaphragm &c. constituting one electrode of a condenser telephone of which the other electrode is of corresponding form, or it may be a part of the listeners' body. A high potential is maintained between the electrodes by a separate battery or by the high tension battery of a wireless set or amplifier when fed therefrom. Fig. 8 shows a cone a<1> driven by a moving coil r supplied through a step-down transformer q, a second transformer k<1> producing fluctuations of potential between the cone a<1> and an electrode e<1> which may be perforated. A condenser w or a resistance or both enables the lower frequencies to be effected electromagnetically and the higher frequencies electrostatically. Various arrangements of transformers in series and in parallel with the windings of ordinary diaphragm, or vibrating reed units, or with the transformer primary of a moving coil instrument are described, and alternatively the electrodes may be fed through a condenser in parallel with the windings. As a further alternative the electrostatic fluctuations may be produced directly by the variations of distance between the electrodes due to the electromagnetic action. Where the human body is used as one electrode the polarizing voltage is applied through a handle, bracelet, &c., and the diaphragm may have an insulated surface to prevent shock.
