Title: A Method of Pumping a Hot Heat-Transfer Fluid in a Circulatory Heat-Transfer System.
Inventor: PRIEST ERNEST HORACE
IPC: F04D13/04
Filed: 1965-11-12
Abstract: 1,171,114. Centrifugal pumps and compressors. E.H. PRIEST and G.M. PRIEST. Nov.14, 1966, No.48230/65. Heading F1C. In a circulatory heating system 7, Fig. 2, hot heat-transfer liquid or gas is circulated by a pump 4 driven by a hydraulic or pneumatic motor 3. The pump and motor casings are in fluid communication via a temperature and pressure barrier section 5a. The fluid communication can be provided by direct discharge of the motor fluid into the barrier section, as shown, by permitted leakage between a closed motor circuit and the barrier section, Fig. (not shown), or by an external pipe connecting the barrier section with a detached and axially spaced motor casing, Fig.4 (not shown). The heat-transfer fluid and the motor driving fluid are the same, or are such that their inter-change is not detrimental. Thus, in the event of temperature and pressure fluctuations, transfer of fluid between the motor and pump circuits occurs, thereby avoiding leakage from the system as a whole. The motor may drive several pumps. The motor fluid circuit includes an electricallydriven supply pump 2 and a heater or cooler 6. The speed of the electric motor may be variable. To improve the effect of the barrier section, the shaft 5 may carry a pair of discs, or a pair of impellers which create opposite or unidirectional axial flows in the barrier section. Alternatively, the latter may include a pair of fixed annular baffles surrounding the shaft. The barrier section may be cooled or heated via fins on its outer surface or by an internal heat exchanger through which fluid is circulated by thermo-syphon or pump means.

Title: Improvements in or relating to telecommunications systems

Abstract: 1,205,306. Automatic exchange systems. SIEMENS A.G. 18 Oct., 1968 [19 Oct., 1967], No. 49396/68. Heading H4K. In a stored programme controlled exchange, the peripheral equipment is arranged in groups with different types of equipment in each group, and communication between an equipment group and central control is effected via a first transmission bus, a group control circuit (which includes a coding facility) and a second transmission bus. The first bus U11-U1F is of the multiwire type over which signals are sent in parallel form using slow-acting devices e.g. relays as the senders and receivers. The second bus U2 has electronic e.g. transistorized senders and receivers and transmission thereover is effected in a serial binary code. The second bus is duplicated and fault analysing equipment ASE and manual control equipment FS can be connected thereto for accessing the duplicated central controls. The control circuit AS of each group is addressed in TDM manner by central control using the main second bus or an auxiliary bus. Commands such as read, write, acknowledge &c. may be transmitted on the main or auxiliary buses. Each data message (in either direction) consists of a number of bytes (multi-bit words) of which the first indicates how many bytes are contained in the information portion of the message, the second and third indicate the address of the peripheral equipment and the remaining (up to) four indicate the information. Each byte may be transmitted in parallel form over the second data bus, the full message still effectively being transmitted in serial form. The equipment groups AF1-AF11 each consist of: a threestage folded network having only one path between an inlet on one side of the network and an " outlet " on the other side, some of these " outlets " being connected to intragroup and some to inter-group links; line and trunk circuits; digit receivers; identifiers; registers; and a path finder. A satellite exchange KGV may form part of an equipment group or may comprise an independent group AFF in which case its individual control circuit is connected to the second (serial data) bus via a special data sender and receiver D1, D1<SP>1</SP>. Each group is in effect a PBX having tie lines to other PBXs, all of which are controlled by a common processor. Other features of the invention are described and claimed in Specifications 1,205,305 and 1,205,309.

The latter may be fitted to receive an explosive cartridge 23 detonated by a point 24 projecting upwardly from the piston 18, the resulting pressure acting on the piston to force the hole piercing member 12 through the wall 14. The pointed end 27 of the hole piercing member 12 is ridged in a starshaped manner and may be concavely curved. When the pipe connector 13 is made from, e.g. synthetic plastics, a steel ring may be secured on the inside of the pipe connector at the joint, the bar 10 then being formed with a corresponding supporting step surface to receive the ring during forming of the joint. The pipe connector 13 may be formed with either an annular groove 31 (Fig. 9) to receive a sealing ring 32 of, e.g. rubber, or with an integral inwardly projecting sealing lip, to engage the edge portion 28<SP>1</SP> of the hole.

Synthetic yarn is crimped by passing it along a path for a first time, returning the yarn to the path for a second time, twisting the lengths of yarn as they pass along the path and subsequently separating the yarn lengths. The yarn is drawn, heated and cooled during crimping. As shown, the yarn is passed twice in a twisted path between rods 11 and 16. The yarn lengths are twisted about each other in opposite directions on either side of twisting pin 18, which inserts false twist into the yarn. At the start of operation the yarn lengths pass on either side of pin 18 and the spindle 10 is then rotated manually to insert the required number of turns of twist in the yarn lengths. The yarn can be heated prior to twisting. The yarn can be drawn prior to twisting or after the yarn has passed along the twisting path for a first time, see Figs. 1 and 2, not shown.

Abstract: 1299910 Lamps J OETIKER 30 Oct 1970 [7 Nov 1969] 51795/70 Heading F4R [Also in Division G5] An optical element for use in the production of illuminable advertising signs, decorative walls, signalling devices and similar apparatus comprises a plane or curved translucent plate 2 on which there is a grating 4, 5 having at least ten apertures 3 in each square centimetre of surface and comprising a coloured covering layer 5 superimposed on an opaque layer 4 made with a specular surface i.e. it is a good optical reflector. The layer 5 covers layer 4 except preferably at the edges where layer 4 may extend a distanced (about 0À2 to 0À5 mm.). During daytime natural light impinges on layer 5 and is reflected by the top surface of layer 4, appearing to the observer at a distance as a uniform sheet the colour of layer 5. At night, artificial light from, e.g. strip lamp 7 interposed between the element and a reflective housing 1, passes through plate 2 (rays 9, 10) and apertures 3, appearing to the observer as a uniform sheet the colour of the translucent plate 2. Layer 4 may be replaced by several layers (Fig. 2, not shown) of dense material so that it is ensured that no light can pass through them, layer 5 being set back distance d to prevent any light from inside housing 1 passing through it (see rays 10). Layer 5 may be weatherprotected by coating with a UV absorbent layer, e.g. of transparent acrylic lacquer. The grating may alternatively be situated in the interior of the plate 2.
