Title: Valve for a filter
IPC: F16K11/083
Filed: 1972-03-28
Abstract: 1393181 Valves PURDUE RESEARCH FOUNDATION 28 March 1972 [5 April 1971] 14350/72 Heading F2V [Also in Division B1] A rotary plug cock valve 13, which is designed for use with a filter assembly 11, comprises a tapered plug 57 within the body of which two separate passage systems are defined. The first, shown to be in its operative state, is delimited by inner and outer wall sections of the plug 39, 37, respectively, so providing an outer annular chamber 55 which is open to a right-hand lateral passage 19 and an inner chamber 50 which is open to a left-hand passage 19 (as shown by flow arrows), and forms a surge chamber with a relief valve 69. The second passage system, which is placed in the operative state by rotation of the plug through 90 degrees from the position shown, is defined by a tubular member 61 which extends across the plug and is sealed relative to the outer wall section 37, such tubular member being aligned with this valve lateral passages 19 (Fig. 5, not shown). Sealing rings 73 are provided in the housing around the lateral passages 19. Attachment of the valve 13 to the filter assembly 11 is by way of a hinged band 47 of U-shaped cross-section, the band engaging peripheral flanges on both the valve 13 and the assembly 11. With the valve in the operative state shown in Fig. 4, fluid supplied to outer chamber 55 passes to an outer channel 51 within the assembly. From the last-mentioned channel, the fluid passes through an annular filter 52 and into a central passage 49 wherefrom it flows into the inner chamber 50 and hence to the valve outlet 19. If the valve plug is now rotated through 90 degrees, the filter assembly 11 is by-passed and fluid flow between lateral ports 19 takes place solely through tubular member 61.

Title: Improvements in a motor vehicle with a displaceable engine
IPC: B60K5/10
Filed: 1948-05-27
Abstract: 661,658. Change-speed control. DOORNE, H. J. VAN. May 27, 1948 [May 29, 1947], No. 14371/48. Class 80 (ii). [Also in Group XXXI] Relates to a displaceable engine unit in a motor vehicle (see Group XXXI) in which the engine unit is displaced relative to the vehicle frame and change speed control lever 37 to permit of maintenance and/or repair. The change speed gear of the unit is controlled through a shaft 32 rotatably carried in a bracket 33 carried in a beam 4 forming a slide on which the unit is mounted. Connected to the shaft 32 within the bracket 33 is a member 35, which is normally engaged by a knob 36 on the gear lever 37 universally jointed at 38 in a housing 39 on to a plate 40 secured to one of the beams of the vehicle frame. The plate 40 and the bracket 33 are held together by studs 45 on a plate 43, the studs being normally urged into position by a spring 44. When it is desired to break the connection between the gear lever 37 and the member 35 preparatory to moving the slide, the gear lever is brought into its neutral position and raised so a ball 41 is pressed into a groove 46 instead of into a groove 42. In raising the gear lever a plate 47 secured to the lever engages the plate 43 and thereby releases the studs 45 from the bracket 33 against the action of the spring 44.

Title: Improvements relating to temperature-sensitive regulating apparatus
IPC: G05D23/275
Filed: 1949-05-30
Abstract: 666,177. Thermally-actuated valves. SULZER FRERES SOC. ANON. May 30, 1949 [June 7, 1948], No. 14392/49. Class 135 [Also in Group XIII] Regulating apparatus influences a regulating member as a function of the rate of change of temperature of a medium by reason of the different rates of expansion or contraction of two sections 2, 3, of different heat capacity, of a length of pipe' 1 through which the medium flows. As shown, a piston 14 is supported by rods 10 and springs 7 between posts 12 and moves within and closes a grooved cylinder 15 secured to a bracket 4 mounted at the join of the thicker walled section 3 of an insulated pipe 1. The hollow ported piston forms a chamber 22 which communicates by a pipe 21 with a regulating member, e.g. through a servomotor. When the piston 14 is raised by the relative expansions of the pipe sections 2, 3 due to temperature changes, the piston ports 16 communicate with a cylinder groove 19 which releases the oil pressure and when the piston is lowered, the chamber is supplied with oil under pressure from a pipe 18 and a groove 17. By making the sections 2, 3 of different lengths or materials, or by having springs of different characteristics, the piston 14, or, as in a modification, a lever pivoted on the bracket 4, may be controlled according to the magnitude of the temperature as well as to its rate of change.

Title: Electrical connection between a conductor and the braided conductor of a shielded cable
IPC: H01R9/05
Filed: 1957-05-07
Abstract: 814,050. Sleeve couplings. AMP Inc. May 7, 1957 [May 7, 1956], No. 14495/57. Class 38 (1). A grounding conductor B is connected to the braided conductor 14 of a shielded cable A by a connector C consisting of inner and outer metallic ferrules 22, 20 respectively connected, preferably and as shown at one end, by an annulus 26 having in it an aperture 32 of the same diameter as the core 29 of conductor C. The connection is made by pushing the inner ferrule 22 under braided conductor 14 and over insulation 12, the core of conductor B being then pushed into the outer ferrule 20 until it is visible through aperture 32, the assembly being then crimped. V-shaped slots 42 in ferrule 20 assist the easy crimping of the ferrule and close up to form slits 43 (Fig. 6, not shown). Alternatively, the assembly may be partly crimped before conductor B is inserted and the crimping completed after it has been inserted. An insulating sleeve, e.g. of P.V.C., may cover the connector (Figs. 5 and 6, not shown). In the embodiment of Fig. 7, a conductor 28 connects two connectors C, C<SP>1</SP>, so that two shielded cables may be connected in series, conductor 28 being inserted through a hole in the annulus of connector C so that it can be connected to a cable, while the connector C<SP>1</SP> has an additional hole 32 for the grounding conductor B. The holes may alternatively be in the outer ferrules, or a hole may be formed in the end of a rib extending longitudinally of the ferrule. The connector is preferably formed so that the ferrules and annulus are integral, e.g. by a tube drawing operation, but it may be constructed from three separate pieces welded together.

Abstract: 1,035,434. Strip - perforating machines. PURDY & McINTOSH (ELECTRONIC DE. VELOPMENTS) Ltd. April 7, 1965 [April 10, 1964], No. 15027/64. Heading B6W. Apparatus for perforating a tape for controlling a typographical composing-machine wherein characters are allocated to two different cases and two different rails, is arranged to produce the necessary functional code signals (shift, unshift, upper rail, lower rail) in the tape only when the required signal differs from the preceding functional signal, and when a functional change is necessary for the casting of the character. For example, certain characters appear in different styles (upper and lower case roman and italic) in each of the four rail groups, in which case the correct group must be operational, while other characters, such as numerals, may be duplicated in two or all of the groups, in which case they can be cast with the machine in more than one functional state. For example, if the previous state of the machine is UNSHIFT-UPPER RAIL, and a character to be cast is repeated in both cases of the upper rail, no change is necessary and no functional signal will be inserted. The keyboard signals are applied to the inputs of a diode matrix, which are selectively connected to six outputs to the perforator for character identification codes, and to outputs representing functional requirements, i.e. MATRIX SHIFT, MATRIX UNSHIFT, MATRIX EITHER SHIFT OR - UNSHIFT, MATRIX SHIFT CONFORM, MATRIX UPPER RAIL, MATRIX LOWER RAIL, MATRIX EITHER UPPER OR LOWER RAIL, and MATRIX RAIL CONFORM. "Conform" represents characters requiring one only state of the machine for casting. For printing in small caps, a function key switches the keyboard to a different set of inputs. The circuit of Fig. 2 is arranged to produce a function signal in the tape only when the required conditions apply.
