Patent GB-270263-A (GB)
Abstract: 270,263. Siemens & Halske Akt.-Ges. April 27, 1926, [Convention date]. Inductances.-An inductance coil, particularly for use as a loading coil for telephone lines, the core is formed as a hollow ring, one or more windings being arranged within the hollow space and one or more further windings being wound round the core. In the construction shown in Fig. 1. the annular core 9 is formed in two parts having annular recesses for the reception of the inner windings 5, 6. The cores are preferably formed of compressed iron powder. The recesses may be nearer the outerperiphery than the inner in order to obtain the same magnetic reluctance along the whole of the path for lines encircling the inner windings. Conduits 11, 12 are provided for the leads. To reduce leakage, one or more protective screens 13 of highly magnetic material may be wound in the form of a band round the core. An air gap 30, Fig. 4, may be provided between the halves of the core. The conductors 5, 6 within the core are included in the circuit of one pair of conductors, the second pair being loaded by coils 7, 8 wound outside the core. As these windings are at right-angles there is no coupling between them. Two similarly wound cores may be employed for loading two physical circuits and a phantom circuit. In each of the four wires are connected in: series one of the coils wound within the core and one of the coils wound round the core. Slight undesired coupling between the circuits may be eliminated by placing one or more turns in series with the inner winding, so that an opposite magnetic coupling is produced, In a modification shown in Fig. 5, the two cores 9, 10, in which are wound the coils 15, 17, 23, 25, are wound with a single coil 33, replacing the four outer windings. Magnetically subdivided screens 34 may be arranged between the cores 9, 10, and the whole coil or portions thereof may be enclosed by metal screens to avoid capacity and inductive influences.

Title: Method and apparatus for detecting the degree of contamination of waste water
IPC: G01N33/18
Filed: 1974-06-18
Abstract: 1467312 Measuring contamination of water K HAYASHI 18 June 1974 [21 June 18 Aug 1973] 27058/74 Heading G1A Apparatus for measuring contamination of water comprises a by-pass pipe, connected to a main pipe for carrying the water and having a measuring pipe at its outlet comprising a constant flow device 37 on pipe 9 with nozzle member 31; a source of light as 11, 13, a sensor of fluorescent light 14 and sensors 21, 22 for measuring infrared and ultraviolet light absorbed by the water. As in Fig: 1 (not shown) the by-pass pipe has a multiple inlet from various parts of the cross-section, a pump and a stirrer. Pipe (9) is surrounded by an annular overflow (7), which returns water to the main pipe. The sensor outputs are processed by a computer (17) to measure and record the fluorescent oil component, the total oil component and the total contaminants. The total oil component is obtained by adding the measurement of the fluorescence to the difference of the measurements of absorption of infrared and ultraviolet. When one component is excessive circuit (23) operates valve (18) returning water through pipe (20) to oil water separator (2) and an alarm may operate. Connection 30, Fig. 2, connects the by-pass pipe to pipe 9 mounted in casing 35 and has a wire net filter 27, rotated by electric motor 28, with discharge port 29 and vacuum nozzle 42. Nozzle member 31 has a flat rectangular passage 140 and guide-member 32 having grooves 33 as wide as nozzle 15, which thus forms a laminar flow. Discharge pipe 39 returns water to the main pipe. Sources 11 and 13 may be gallium arsenide and mercury lamps respectively. Light sensors 14, 21, 22 may be photo-multipliers or semi-conductors such as solar cells.

Title: Improvements in controlling arrangements for the pneumatic operation of automatic machines for feeding and shaping molten or plastic glass
IPC: C03B7/10
Filed: 1930-09-11
Abstract: 356,484. Glass manufacture. PEARSON, T. F., A4, Baghill Lane, Pontefract, Yorkshire. Sept. 11, 1930, No. 27113. [Class 56.] Blowing; delivering molten metal.- Relates to a device for controlling the operation of pneumatically or hydraulically actuated machines for feeding and shaping molten glass, particularly for making bottles. According to the invention, the valves for controlling the supply of compressed air to the various parts of a machine are operated by cams which have pin- and-slot connections with their driving pinions, and means are provided to adjust the position of any pin in its slot in order to alter the timing of the valve operated by the cam. The device comprises a number of valves 17 operated by cams 13-15, and each cam is rotated by one of a train of pinions 4-8 which are driven by a shaft 1. Each of the pinions 4-8 is secured to a hollow sleeve 9 containing a spindle 10 that rotates with the sleeve but is movable longitudinally within it. A cam 13 is mounted on the sleeve and is forced to rotate with it by a pin 11, secured to the spindle 10, which projects through a longitudinal slot 30 in the sleeve and engages a groove 12 in the cam. The groove is inclined, so that axial movement of the spindle 10 causes the cam 13 to rotate relatively to its driving-pinion. Each spindle can be moved by a screwed rod 21, so that any of the spindles can be moved in order to adjust the time of the valve operated by the cam relatively to the other valves. Pairs of valves may be interconnected if desired, so that any desired period of dwell of the mechanism operated a cam can be obtained.

Title: Apparatus for tempering liquid chocolate and for feeding a depositor or like machine
Inventor: GODDARD JAMES ALAN
IPC: A23G1/18
Filed: 1952-10-31
Abstract: 719,520. Tempering chocolate. GODDARD, Ltd., J. A., and STEPHENS, SMITH & CO Ltd. Oct. 26, 1953 [Oct. 31, 1952], No. 27444/52. Class 86 [Also in Group VI] Chocolate to be tempered is put in a hopper 1 provided with stirrer blades 6, 8 and 9 and a water jacket 2, and drops through openings 86 to a jacketed, cooling system 18 with feed worms 19 and 21 from which it is discharged into the receiver of an enrobing or other using machine (not shown). This initial tempering is done at 84-94‹F. When the enrober receiver is fully charged the apparatus of Fig. 5 is readjusted to vary and control the temperatures of the various jackets and of the rate of feed and discharge of the chocolate, so that the chocolate ceases to be tempered but is only cooled to 95-105‹F. and fed in drips to the large volume of tempered chocolate in the enrober hopper whereby it becomes tempered by contact with the large bulk of tempered chocolate. The cooled chocolate surplus to the drip feed is returned to the hopper 1. The circulating and control apparatus, Fig. 6, is operated as follows: The apparatus is first heated up by passing steam warmed water through the various jackets, 2. 26, 29 &c. as follows. The thermostat switch 63 is set high so that electromagnetic valve 50 is open for heating and valve 49 is closed to prevent cold water from inlet 38 passing to the jacket 26. Valve 47 is opened and the steam and water mixing valve 41 is adjusted so that warmed water can circulate through jacket 26, steam being supplied at 42. Pump 51 is then started and forces warmed water into the jacket 2 and at the same time a known type of thermo circulator 55 draws water through pipe 57, heats it and returns it to the jacket 2. When jackets 26 and 2 are warm valve 47 is closed and the hopper 1 is charged with a batch of heated chocolate when the whole system becomes thermostatically controlled from thermometer 64, Fig. 5. If the chocolate at 64 is too hot, the thermostat switch 63 allows current to open magnetic valve 50, so that cold water passes by pipe 48 to jacket 26. The starting circuit for pump motor 52 is also connected to motor 11 so that the stirrer cannot be started until the pump 51 is started. The chocolate is circulated between the hopper 1 and the cooler 18 until the batch in the hopper 1 is tempered. The valve 30 is then adjusted to allow the chocolate to be rapidly discharged at 28 into the receiver of an enrober or other using machine. The hopper 1 is then recharged and valve 30 is set as in Fig. 8 (not shown) so that the apparatus acts as a pre-cooler only, which delivers sufficient drips of pre-cooled chocolate by pipe 31 continuously to the enrober receiver to maintain by drip a full charge therein of now tempered chocolate while the surplus is diverted and returned by pipe 32 to the hopper 1.

Filed: 1935-10-04
Abstract: 463,660. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. Oct. 4, 1935, No. 27462. [Class 40 (iv)] Apparatus auxiliary to the normal exchange equipment for enabling certain subscribers to set up frequently wanted calls by means of calling keys such as K1, K2, one for each subscriber who can be called in this manner, comprises a number of switches LF, each position of which is individual to a particular connection and is adapted to be marked by the corresponding calling key. Each line is therefore connected to several positions in banks lfm3, 4 as a calling line and to several positions in banks lfm5, 6 as a called line. The subscriber B wishing to call the subscriber A presses the corresponding key K1 without removing his receiver. Relay Q energizes, locks and connects up the cut-off relay of the normal line circuit and start relay ST, whereupon the idle switches LF hunt for the marked position. Relay K then energizes, busying the position and connecting up KA.. The subscriber B takes off his receiver after releasing key K1, whereupon line relay S energizes and short-circuits Q, which in turn releases ST. If the wanted line is idle, relay T energizes and connects up switching relay TT. Ringing current is applied continuously over ring-trip relay F, which pulls up on reply and completes the talking circuit. If the wanted line is busy, relay T does not energize and busy tone is sent. If, however, the line becomes idle before the calling subscriber hangs up, T, TT pull up and the line is rung, busy tone being replaced by ring-back tone. If the calling subscriber does not press a key long enough for Q to lock up, he receives dialling tone on lifting his receiver. The rectifiers MRA, MRB are arranged to prevent any effect on Q when the cut-off relay operates. If the calling subscriber fails to lift his receiver after pressing a key, timing circuits bring about the release of the switch LF. By pressing two or more keys, a subscriber may set up several connections simultaneously over two or more switches LF for conference purposes. Incoming junction calls may be extended over the switches LF by means of a relay group or switch which is controlled over the junction so as to perform the functions of the keys K1, K2.
