Title: Heat exchange apparatus
IPC: B01D1/22
Filed: 1964-10-21
Abstract: 1,039,900. Tubular heat exchangers for heating or cooling liquids. CHEMETRON CORPORATION. Oct. 21, 1964 [Nov. 7, 1963]. No. 42862/64. Headings F4H and F4S. [Also in Division B1] Adhesive, semiplastic or other more highlyviscous fluid materials as they flow through a tube 21a around which is arranged a jacket 25a containing a heating or cooling medium, are agitated by scraper blades 45 which are mounted on a rotary shaft 40a and scrape the inner surface of the tube, the blades oscillating during rotation with an amplitude which increases along the shaft from one end thereof (the lefthand end as shown) at which it is substantially zero. Oscillation is effected by mounting one end of the shaft eccentric with the tube, the other end being concentric. The shaft may have a taper converging towards its eccentrically mounted end. The blades are retained in contact with the tube inner surface by centrifugal force and by the resistance of the treated fluid. Contact may be assisted by springs (not shown). The blades are mounted on the shaft in sets each comprising two or more blades. As shown, adjacent sets overlap and the blades at the concentrically mounted end of the shaft may be relatively long. The mounting means for each blade (see Fig. 5, not shown) comprises two supporting lugs 47 for the blade edge nearest the shaft, each having a radiused recess shaped to receive the edge of the blade and to permit oscillation of the blade; and retaining pins 49 projecting from the shaft which extend with clearance through corresponding enlarged apertures 50 in the blades. Heating or cooling fluid enters the jacket 25a through a conduit 35a and leaves through a conduit 36a. The jacket is provided with a covering 27a of heat insulating material. A continuous flow of the treated fluid enters the tube 21a through a conduit 37a at the concentrically mounted end of the shaft and is discharged through a conduit 39a.

Title: Tunnel diode storage circuits
Inventor: PARADINE CHRISTOPHER
IPC: H03K19/10
Filed: 1964-10-23
Abstract: 1,122,808. Tunnel diode circuits. ELLIOTT BROS. (LONDON) Ltd. 20 Oct., 1965 [23 Oct., 1964], No. 43245/64. Heading H3T. A two-state storage circuit includes two tunnel diodes 3, 7 connected in parallel across a source of potential difference 4, switching means 11 for changing the stable state of one of the diodes, and feedback means 12, 13 interconnecting the diodes to prevent the other diode from changing its state in response to the input signal. The source of potential 4 provides a sinusoidal wave superimposed on a D.C. bias. Each positive half-cycle drives diodes 3, 7 from their low voltage state into their unstable state, and an input signal at 11 causes one diode (or the other diode, depending on the polarity of the signal at 11) to be driven to its high voltage stable state ahead of the other, the feedback paths 12, 13 ensuring that the other diode is returned to its low voltage stable state. An output signal may be taken from, for example, points 14, 15, and connected to the corresponding points of similar circuits for the performance of logical functions. For example, one circuit may provide the load 11 of another, the voltage difference 4 of the second lagging in phase behind that of the first, preferably by 120 degrees. The terminals 14, 15 of one circuit may be connected in common through respective resistors to the output terminals 14, 15 of three other circuits, the one circuit then performing, for example, a majority function. The resistors in the circuits may be replaced by capacitors, inductors, tunnel, backward or ordinary diodes. The sinusoidal component may be removed from source 4, the circuit then acting as a D.C. bi-stable circuit.

Title: Apparatus in track aligning machines and track aligning method
IPC: E01B35/00
Filed: 1964-11-06
Abstract: 1,076,395. Aligning railway tracks. F. PLASSER, [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Nov. 6, 1964 [NOV. 21, 1963], No.45327/64. Heading G1F. A method of aligning railway tracks at curves therein utilises two chards 1, 2 which extend from a point A into the as yet uncorrected track region within the track one rail 5 of which is shown. The chards may be in the form of wires and these pass between spaced electrical contacts (not shown) on nuts 11, 12 mounted on a screw-threaded spindle 8 driven by a motor 7. The spindle 8 is mounted transverse to the track on a carriage with wheels 4 and comprises two sections 9, 10 of relatively course and fine pitch screw threads respectively for the nuts 11, 12, the ratio of the pitch of these two sections being proportioned to the arc heights F, f of the chards 1, 2 at the point M at which the spindle is situated. The contacts on the nuts 11, 12 are each connected in series with a signal lamp and voltage source, so that if the wires forming the chards 1, 2 touch the contacts the respective signal lamp will light. In use when it is desired to correct the position of the track at the point C, the spindle 8 is rotated to position the nut 11 so that both its associated lamps are extinguished. The nut 12 will accordingly be moved in dependence on the ratio between the arc heights F, f. If the track position is incorrect at the point C, one of the lamps associated with the nut 12 will be lit and will give the direction in which the track must be moved to position it correctly. The track is then moved to extinguish the lamps associated with the nut 12. If desired the current which lights these lamps may also be used to actuate solenoid operated valves to operate one or other of two hydraulic rams positioned either side of the track and which then move the track until its position is correct. Also the wires forming the chards 1, 2 may be replaced by radiation beams, in which case shutters, transmitters or receivers take the place of the contacts on the nuts 11, 12.
