[Also in Group XXIX] In a thermostatic device of the type in which a diaphragm is caused to operate a valve when displaced by an expansible medium contained in a probe, the probe contains a plurality of solid bodies which are surrounded by a liquid, the solid bodies having a coefficient of expansion greater than that of the liquid. A probe 8 contains a number of solid particles 9 of polyethylene, the remaining space being filled with a liquid 12 of high viscosity e.g. glycerine. A net 11 is placed across the mouth of the probe. Upon expansion of the polyethylene particles, the increase in pressure in the probe is transmitted to a diaphragm 6 of polytetrafluoroethylene or caoutchouc which is disposed around a closed cylinder 4 containing a spring 5 which urges a dished member against the top wall of the cylinder. A spindle 3 projects through a hole in the top of the cylinder to cooperate with the said dished member and is connected at its upper end to a cylindrical valve body 1 which is disposed in a chamber having a valve seat 2. The flow of hot water to a radiator through the valve means is decreased upon upward movement of the cylinder, spindle and valve body and upon contraction of the polyethylene particles, these members are urged downwardly by a spring 13 mounted on the spindle 3. The probe 8 is connected to a housing 7 which is screwed to the valve housing to permit axial adjustment therebetween. In the embodiment of Fig. 2 (not shown) the probe 8 is connected to the housing 7 by means of a capillary tube.

Abstract: 329,684. Automatic Telephone Manu facturing Co., Ltd., and Gillings, C. Feb. 23, 1929. Metering systems.-In an automatic exchange system, successful incoming calls as well as outgoing calls over a subscriber's line are metered either on another or on the same meter. This may be effected by the extension of booster battery at the connector forward as well as backward. when the called subscriber replies. Fig. 1 shows a line switch in which outgoing calls are registered on the meter OM by the connection of earth to the fourth wiper 25 at the switch ahead, while incoming calls are registered on the meter IM by the connection of booster battery to the test wire 17 in the connector when the called subscriber replies. Calls of both classes may be registered on the same meter by adding the dotted connection with resistance 27 and omitting the meter IM. In a modification, outgoing calls are metered by the connection of booster battery to the test wiper. Fig. 3 shows a connector modified to extend booster battery forward as well as backward. When switching relay H operates change-over relay C re-energizes over contact 126 and locks at contact 139. The wanted subscriber is rung, and ring cut-off relay F energizes. Relay C is now disconnected, and during its release period, booster battery from wire 148 is connected back over test wire 119 and forward over test wiper 130. If metering of incoming calls is not desired, terminal 150 is strapped to earthed terminal 151 instead of to terminal 149 as shown.

Abstract: 1,131,229. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 11 Feb., 1966 [26 Feb., 1965 (2)], No. 6166/66. Heading H1K. Portions of mutually isolated low resistivity semi-conductor regions 12, 14 on a substrate 20 are removed through an insulating mask 22, and high resistivity material 30, 31 is epitaxially deposited in place of the removed material. Removal is preferably by vapour etching, the etching and re-deposition stages both being carried out in the same apparatus simply by changing the constitution of the vapours impinging on the substrate. The regions 12, 14 are isolated from the substrate 20 by insulating material 17, e.g. silicon oxide. Manufacture of the illustrated embodiment comprises initially forming an array of mesas (11-15), Fig. 1 (not shown), by masking and etching an N+ Si body (10). An insulating silicon oxide coating (16) is then grown over the surface including the mesas, and the parts of it not actually on the mesas are lapped or etched away to leave only the parts (17), Figs. 2, 3 (not shown) covering the mesas. A support layer (20) of epitaxial monocrystalline, polycrystalline or amorphous Si is grown over the mesas and their covering (17), and the Si body (10) is then lapped and polished away to leave only the mutually insulated and separated mesa regions (11-15) in a substrate (10). An oxide layer 22, Fig. 7, is deposited or grown and apertures 26, 27 are formed therein by etching. The process of vapour etching and redeposition is then effected, and discrete devices such as transistors, diodes and resistors are diffused or deposited in the resulting regions 30, 31. An integrated circuit is completed by the deposition of metal strips linking the devices. In one form layers of Mo or W are formed on the tops of the mesas initially, thereby providing a lowresistivity path lining the cavities in which the devices lie. The substrate surface on which the selective etching and redeposition occurs preferably lies in a plane other than a (111) plane.

Abstract: 1286144 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 29 Jan 1970 [5 Feb 1969] 6295/69 Heading G6C A fuel stringer which includes a number of fuel elements comprising clusters of fuel rods supported in structural sleeves, has its fuel elements carried by supporting means of openwork structure disposed externally of the fuel element sleeves. Because the supporting means is of openwork structure external cooling of the sleeves in the stringer during operation is little impaired. In the construction shown, a stack of fuel elements 2 of which the main structural components are graphite sleeves 4 carries a distance piece 3 at its upper end. The sleeves 4 and distance piece 3 are held in superposed engagement by a support structure 5 consisting of a multiplicity of helical runs of wire 6, the pitch of the helix being such that each run makes two revolutions of the sleeves 4 and distance piece 3. Radially slotted annular metal support members 7 are located at each end of the assembly of sleeves 4 and distance piece 3, the incoming wire 6 passing from alternate slots thereof across to the next adjacent slot in one direction and then becoming outgoing. One end of the wire 6 commences at the lower member 7 where a swaged end thereof is held in a tapered hole in the member 7, the hole being in place of one of the slots 8, and the other end of the wire, after becoming outgoing from the last available slot in the lower member 7, is clamped to its adjoining incoming wire. The support members 7 lie on the lower and upper edges of the lowermost sleeve 4 and the distance piece 3, respectively, and are held both by the tension in the wire 6 and also by mechanical means. At the lower end, a metal locking ring 12 is screwed on to the lower member 7 with interposition of a metal ring 13 which serves to protect the wire loops projecting beyond the end of the member 7. A metal connecting member 17 is screwed on to the upper member 7 with interposition of a metal ring 20, the member 17 having a depending skirt portion 22 in which is screwed a flow restrictor ring 23. The ring 23 provides a restriction to choke the ingress of coolant from the annulus between the stringer and the fuel channel wall of the moderator should there develop a gap between the distance piece 3 and the upper member 7 as may be caused by relaxation of the wire 6. The upper portion of the member 17 consists of a number of spring fingers 24 each having a hooked end 25 for engagement with a suitably shaped upper, non- fuel, continuing part of the complete fuel stringer, which continues upwardly to a charge plug at the charge face of the reactor. In an alternative construction of fuel stringer, the fuel elements are each provided with an openwork structure and these structures are interconnected to form the stringer.
