Patent GB-1025710-A (GB)
Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1964-10-29
Abstract: 1,025,710. Automatic exchange equipment. SIEMENS & HALSKE A.G. Oct. 29, 1964 [Oct. 29, 1963], No. 44082/64. Heading H4K. In a telephone system where the dialling information is represented by the application of earth to the speech wires through various connections of rectifiers and detected at the exchange by applying two voltages of opposite polarity to the wires through relays which indicate the presence or absence of a conductive path, the replacement of one voltage by the one of opposite polarity and the final removal of the detecting unit from the wires is made in response to the above detection by the relays. As shown in Fig. 3, the rectifiers G 5  ... G 7  in the sub-station N are connected to the speech wires by the dialling push-buttons T 1  ... T 15  and the presence of a conductive path to earth is detected in the receiver TE by relays A, C when- 48 v. are applied to the wires and by relays B, D for +48 volts; the means for taking this dialling information from the relays to the store is not shown. When a transmission bridge U E  is seized the - 48 v. is first applied and if one or both of the associated relays A, C is actuated, i.e. there is a conductive path to earth, then by means of relay AC the -48 v. is removed and the + 48 v. applied through relays B and D. If one or both of these are actuated then by means of relays BD the a receiving unit TE is removed from the wires at contacts 7 sh, 8 sh. In the absence of a conductive path and the hence non-actuation of either relayd in each pair the switching of the 48 voltages is effected by transistors T1 and T2. These are rendered conductive by the 48 v. and a 10 kHz voltage induced into winding 17 or 24 over the core Sp1 or Sp2. If there is no conductive path the transistors are not blocked by current flowing in windings 18 or 25 and themselves actuate the relays AC or BD instead of the detecting relays, to switch the 48 voltages. In an alternative arrangement shown in Fig. 4 there are no magnetic cores Spl, Sp2 and each detecting relay has an associated transistor T3 ... T6. If any of the relays A .. D are not actuated no earth is applied to the associated transistor and it is rendered conductive and by means of the series connected relays AN ... DN actuate the relays AC and BD. The transistors are made non-conductive again as the 48 volts is removed by contacts 47bd and 46bd. The unit k shown in Fig. 3 monitors the loop current and as soon as this is interrupted by button contacts 6T 1  ... T 15  relays SS and SH switch the receiving unit TE into the wires at 7sh and 8sh. This is conditional upon relay D 1  which is actuated when a transmission bridge is first seized. The transistors and relays may be replaced by magnetic cores. If the coding is of a nature such that either relay A or C, B or D will always be actuated then the transistors T 1 , T 2  or T 3  ... T 6  are unnecessary. Buttons T 11 -T 15  are for initiating special switching processes such as break-in, call-back or calltransfer.

Title: The finishing of textile garments
Inventor: HELLIWELL GUY S
IPC: D06B5/24
Filed: 1960-12-23
Abstract: <PICT:0937307/IV(a)/1> Plant for finishing textile garments comprises a treating chamber which can be closed to enclose garments mounted on forms in a treating zone, a showering means located above said treating zone, a liquor feed pump connected at one side to said showering means and at the other side to a liquor drain from the chamber, means for introducing steam into the closed chamber so that it contacts the form-mounted garments, and hot air blowing and evacuating means associated with said chamber.  As shown stockings on forms 8 carried by a carriage 7 are in treating zone A beneath bell 1.  A fresh carriage carrying untreated stockings is ready outside the treating zone.  On completion of the treating cycle on the first stockings the carriage of untreated stockings is moved along tracks 2 to displace the treated stockings.  The fresh carriage closes a switch to start the rotation of a control camshaft.  This first operates valve 69 to release jacks 3 to lower bell 1. During the descent of bell 1 switch 67 is operated to stop fans 61, 62 which have been circulating drying air over the previous batch of stockings.  When the bell has reached its bottom position in contact with base 2 a second cam actuates valve 70 to bring into operation bell locking means.  A third cam then actuates valve 74 to close valve 26 and the drain from chamber 1, 2, and a fourth cam operates valve 71 controlling valve 11 so that steam flows through tube 9 into the chamber.  The steam is controlled at a temperature of about 225 DEG F. by thermostat 56 and the stockings are preboarded for about 30 seconds.  Valve 71 is then operated to close valve 11 and at the same time valve 74 is actuated to open drain/exhaust valve 26 whilst a further cam opens vents 14.  The next operative cam then re-actuates valve 74 to close valve 26 and at the same time valve 81 is operated to trigger off valve 22 to supply a predetermined quantity of dye solution from tank 19 to the chamber, via pump 24, temperature controlled heat exchanger 27 and spray 18.  The dye liquor collects at the bottom of chamber 1, 2 which is connected by pipe 16 to the suction side of pump 24. Once the predetermined quantity has been delivered this quantity is recirculated in a closed system for a predetermined time. Simultaneously a metering valve 49 and water valve 51 are operated to admit appropriate make-up solutions to tank 19.  After the dyeing treatment there is a further cam operation of valve 74 and valve 26 is opened to drain away the dye solution. Following p  this, vents 14 are closed and steam valve 11 re-opened to flush the system through.  There may also be partial drying and some postboarding of the stockings.  Steam valve 11 is then closed and vents 14 opened.  Valve 70 is then actuated to unlock the bell and valve 69 to raise it.  When the rising bell trips switch 67, fans 61 and 62 are started to circulate hot air over the stockings to dry them, thus completing the cycle of operations.  Specification 810,605 is referred to.
