Abstract: 608,750. Applying wrappers. ASPINALL. H. I. Oct. 4, 1946, No. 29584. Addition to 596,199. [Class 94(i)] Instead of the wrapping strip of the parent Specification being secured by means of a pre-prepared adhesive strip, it is secured by applying to its overlapping edges as the strip is being applied, or by applying to a sealing strip for the overlapping edges of the wrapping strip as said sealing strip is being applied, an adhesive which will set or harden, or is capable of being set or hardened, before the wrapped cable reaches the region of the " cutting- off " means. Alternatively, the wrapping strip is secured by applying to its edges an adhesive capable of being set or hardened sufficiently to enable the strip to be coiled in a holder without the coils adhering, and of being softened by the application of heat or moisture during, or immediately prior to being wrapped about the cable, or by forming the wrapping strip itself of a material capable of softening and becoming adhesive under the application of heat.

Abstract: 519,280. Air storage. KIDDE & CO., Inc., W. Oct. 13, 1938, No. 29651 Convention date, Dec. 24, 1937. [Class 8 (ii)] Gas for the inflation of flotation bags for aircraft, and stored under high pressure, is liberated from its containers by the piercing of a frangible disc, the piercing tool being propelled by the explosion of an explosive charge mounted in it. When the aircraft alights on the water a float - operated switch closes an electric circuit to ignite the charge 39. The resulting explosion detaches the cutter 30 from its support 44 and faces it forward to cut the disc 28. For manually actuating the cutter the knob 46 is faced inwards, this being connected to the cutter through its support member 44. Specification 388,182 is referred to.

Abstract: 976,120. Plate-type heat exchangers. SEPARATOR A.B. Aug. 2, 1962 [Aug. 3, 1961], No. 29717/62. Heading F4S. In a plate heat exchanger of the type provided with closed interspaces between plates alternating with entirely or partially open interspaces and where the plates are clamped to form a pack and fitted in a closed casing; the casing has a supporting wall 1 from which one or more supporting shafts 8 extend into the interior of the casing. As shown, the plates 9 and thrust plate 12 are threaded on shafts 8 (only one shown). Nuts 11 are used to tighten the thrust plate 12 and clamp plates 9 against supporting wall 1. Heating fluid e.g. steam enters the casing at inlet 6, flows through the open interspaces between plates 9 and condensate exits at 7. Fluid to be heated flows into the closed interspaces via pipe 17 and may follow a zig-zag path from one interspace to the next and eventually flows out at outlet 19. Amongst the pack of plates may be arranged a number of plates which touch the casing along three of their four edges (Fig. 2, not shown) to make the steam follow a zig-zag path. Fig. 3 (not shown) illustrates the thrust plate as one wall of the casing. The supporting wall may contain the inlets and outlets for both heat exchange media.

Abstract: 992,399. Air conditioning units. FIRTH CLEVELAND Ltd. Aug. 21, 1961 [Aug. 20, 1960], No. 30080/61. Heading F4V. In heat-exchange apparatus comprising at one side a rectangular heat-exchanger and a cross-flow fan including a bladed cylinderical rotor extending over the length of and parallel to one side edge of the heat-exchanger, the flow of air induced by the fan passes in and out at the same side of the apparatus. A " tangential fan " may be employed as described in Specification 876,611 including external guide means. The air conditioning unit shown in Figs. 1a and 1b comprises two heat-exchanger blocks 4 and 5 forming the evaporator and condenser of a refrigerator and two associated rotors 13, 12, and the guide means includes plates 17, 14, whereby cylindrical vortices V are set up which induce an air flow through the rotors as indicated by flow lines F. The rotor driving motor 8 and refrigerator compressor 6 are mounted in a separate side portion of the housing 1 and the whole unit is arranged for mounting in a wall 18 so that air from a room is cooled by circulation through evaporator 4 while external air is circulated over condenser 5. To minimise noise, the space 32 between the duct walls 24, 26 is formed as a resonator; in addition, parts of walls 26,27, comprise thin membranes to allow the resonator to co-operate acoustically with the remainder of housing 1, and wall 24 carries sound-absorbing material 25. Other air conditioning units are described including different arrangements of the rotors. For example, the air through both heat-exchanger blocks may be circulated by a single rotor having a fixed inner guide member (Fig. 3b, not shown). In another embodiment, Fig. 4b, the heat-exchanger blocks 81, 82, are housed side-by-side and associated with coaxial rotors, and the room air is passed through a filter 94. The air conditioning units may be modified to operate as heat pumps.

Title: Improvements in or relating to teleprinter apparatus
IPC: H04L12/00
Filed: 1961-08-21
Abstract: 940,171. Teleprinter apparatus. SIEMENS & HALSKE A.G. Aug. 21, 1961 [Aug. 22, 1960], No. 30085/61. Addition to 920,263. Heading H4P. In the arrangement claimed in the parent Specification wherein information is passed selectively to one or more teleprinter receiving devices by a control device responsive to a routing signal determining the selective distribution of the information, and set up at the control device, and in which a punched tape is prepared comprising routing signals derived from a control tape followed by the information to be sent to the desired receiving devices, means is incorporated for effectively changing at least a part of a routing signal. In the circuit arrangement, a relay A is connected so that with switch K1 1c open it is not normally responsive to a character which can also be included in a routing signal preceded by the all-blank signal and transmission to the punch-all perforator AL normally proceeds without interruption from the punched tape. If the correction of a routing signal is to be effected, a key is operated subsequent to operation by the previous routing signal closing contact T5 which operates a relay B locking up over contact b1 and preparing a circuit for a relay U and, also, for a relay T. A relay G energized through contact B3 prevents routing signals from being printed on the printer of the key-actuated teleprinter which produces the messages to be transmitted. With a continued running of the tape, a relay P is energized and at contact p4 operates relay T. When the blank signal preceding the routing letter to be changed is scanned, a relay M (not shown) operates and closes contact m7 so that a relay U is operated, and at u3 energizes the magnet A which cuts off the driving circuit of the punched-tape transmitter, and relay P releases to de-energize relay U. The amended routing signal is now keyed in by the message teleprinter and contact 6a, since contact u2 is open and the stopping of the punched-tape transmitter L5 prepares a circuit for relay L through contacts b4, p6 and t2, and with the keying in of the new signal the relay L is energized and effects a delayed release of the relay B so that relays T, B and L are then released to restore the circuit to normal. The arrangement may be used to change functional signals, such as carriage return.
