Title: Improvements in or relating to heat exchangers of the indirect plate pack type
IPC: F28D9/00
Filed: 1961-02-23
Abstract: 901,952. Plate type heat exchangers. ROSENBLADS PATENTER AB. Feb. 23, 1961 [Feb. 29, 1960], No. 6595/61. Class 64 (3). A heat exchanger consists of a stack of identical plates, each plate being pressed as shown in Fig. 5 to provide in both surfaces a number of regularly spaced depressions or dimples 7 and to form corresponding bosses 8 on the opposite surfaces. The plates are assembled face-to-face to form spaces 5, 6 therebetween for the passage of the heat exchange fluids, alternate plates being reversed so that in the spaces 5 the tops of the bosses of the facing plates abut on each other and are spot-welded at 10 whereas in the spaces 6 the bosses of one plate are in spaced registering relationship with the dimples on the facing plate. This arrangement allows the heat exchanger to be used for the treatment of liquids containing, for example, sludge or fibrous material, since such liquids can flow through the comparatively unrestricted spaces 6 whilst steam &c. flows through the spaces 5.

Abstract: 1,043,063. Pipe couplings. W. F. HENDRIKS. Feb. 17, 1965 [Feb. 24, 1964], No. 6775/65. Heading F2G. A pipe coupling comprises a socket member 4 in which is inserted a pipe end 1, 2, an annular, flexible sealing member 5 being interposed between the socket member and the pipe end. The sealing member 5 is of the " cup-leather " type and is held within the socket member 4 by an annular rigid disc 8 which is operatively, pivotally connected to the socket member 4. Fluid pressure in the pipe-line forces the sealing member outwardly of the socket member which outward movement tilts the disc the inner peripheral edges 12, 13 thereof which may be bevelled, thus exerting a gripping action on the pipe end 2 and thus locking the coupling. The coupling is unlocked by the depression of a lip 8a connected to the disc 8 and passing with a clearance through an opening 10 in the socket member. The socket member 4 forms part of a coupling sleeve 14 which is provided with a centring flange 15. In a modification, the disc is pivotally connected to the socket member by a bolt which passes with a clearance through an opening in the wall of the socket member and screw-threadedly engages in a bore in the outer periphery of the disc (Figs. 1, 3, not shown). In the construction of Fig. 3 (not shown) a radially inwardly projecting lip is formed on the socket member diametrically opposite the pivotal connection, a bolt passing with clearance through an opening in the lip and screwthreadedly engaging in a bore in the outer face of the disc to keep the disc in its tilted position.

Title: Improvements relating to circuits for providing recurrent impulses
IPC: H03K21/00
Filed: 1947-03-17
Abstract: 639,719. Pulse delaying circuits. HIGHAM, E. H., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. March 17, 1947, No. 7331. [Class 40 (vi)] Apparatus for providing a train of pulses, the recurrence frequency of which is a submultiple of that of a standard frequency source and having an adjustable delay relative to fixed time instants of the same recurrence frequency, comprises two or more delay circuits which are adjustable over ranges which are integrally related, the delay circuits being tripped sequentially after initiation by a pulse from the standard source. Fig. 1 shows in block schematic form a delay system in which impulses derived from the standard frequency source MO pass through the Divider Gate at a frequency which is submultiple of that of the standard source and which is determined by the setting of the dividing-down circuit CD. The output pulses from the Short Delay Selector have a delay relative to the output pulses of the divider gate which is determined by the settings of the long, intermediate and short delay selectors which operate to give delay periods each of which is an integral number of tenths of the period of the preceding delay circuit as determined by the decade dividing circuits 1, 2 and 3. The decade dividers may comprise conventional synchronized blocking oscillator circuits, Fig. 3 (not shown). Fig. 4 and 5 show a time base and delay selector circuit. Incoming positive going pulses from the divider gate or preceding delay selector circuit are applied at terminal IN to render valve V2 conducting, the negative going pulse at its anode which is applied via C to the grid of V4 and the common cathode resistor causing valve V4 to be rapidly cut-off and to produce a positive pulse at its anode which has a duration determined by the time constant CR. This pulse is D.C. restored by diode D2 and applied to a Miller integrator valve V5 to generate a sawtooth waveform at terminal OUT which is applied to the strobing and gating circuit comprising valves V6, V7. This operates as described in Specification 639,722 to produce a signal at its output which is synchronized to some specific pulse applied from the decade divider to terminal DEC, the actual synchronizing pulse selected being dependent on the setting of potentiometer R3. The output from the long and intermediate delay selectors is used to trip the succeeding time base and in the case of the last or short delay selector may be used to trip a gating circuit to let through a pulse to the output from the standard frequency impulse source. Alternatively the output signal may be taken from the short delay selector.

Abstract: 457,576. Hinges. UNITED STATES RUBBER PRODUCTS, Inc., 1790, Broadway, New York, U.S.A. March 11, 1936, No. 7345. Convention date, March 13, 1935. [Class 65 (ii)] An oscillating joint, for example for a spring shackle, comprises a resilient bushing 16 interposed between and secured to inner and outer members 10, 12, and a metal ring flange 17 vulcanized within the bushing at each end thereof to resist axial flow of the rubber. The bushing is shown formed in two parts to facilitate assembly, and is vulcanized to both inner and outer members, the outer member 12 being a thin sleeve also formed in two parts and inserted into the spring eye 14. In a modification, the rings 17 are formed by end flanges of an intermediate metal sleeve embedded in the rubber, which thus forms separate bushings inside and outside the intermediate sleeve. The Specification as open to inspection under Sect. 91 describes also a joint comprising two concentric one-piece rubber bushes, with an intermediate metal sleeve, placed between the inner and outer members, without any ring or flange to restrain the rubber ; the inner rubber bush abuts against the shackle links, and the outer member may be clamped within the spring eye. The rubber may be under sufficient compression to render vulcanization unnecessary. This subject-matter does not appear in the Specification as accepted.
