Title: Hydraulic rock breaker circuit for an excavator
IPC: G05B11/60
Filed: 1977-05-10
Abstract: 1524939 Hydraulic control circuits CATERPILLAR TRACTOR CO 10 May 1977 [4 Oct 1976] 19540/77 Heading F1P [Also in Division F2]  A hydraulic control circuit, Fig. 1, has a priority valve 15 between a first circuit supplying a motor 18 and a second circuit supplying a motor 26 which supplies all the fluid from a pump 11 to the first circuit until the pressure thereof reaches a predetermined maximum and thereafter maintains the predetermined pressure in the first circuit and diverts all available flow to the second circuit. The motor 26 drives an impact rock breaker mounted on a boom which is slewed by the motor 18. When the motor 26 is to be operated whilst fluid is supplied to the valve assembly shown in Fig. 2 the move spool 79 to the right and spool 72 upwards. This causes spool 61 to move to the right, when the pressure is high enough, to block communication between inlet port 57 and motor port 59 and direct the available fluid to motor port 60 for the rock breaker circuit. When all available flow is directed to motor 26 a check-valve 87 will close so that a dual stage relief valve 97 will become responsive to the pressure in port 60 and line 23. This allows the rock breaker to be operated at a higher pressure. After lubrication pressure has built up in motor 26 a pressure responsive switch operates a pilot valve 31 to communicate a signal through line 33 to chamber 113 of relief valve 97 to move piston 111 to the left to move relief valve 105 to the second pressure.

Title: Improvements in or relating to gaseous conduction electrical rectifiers for alternating current
IPC: H01J17/00
Filed: 1928-07-10
Abstract: 294,208. Westinghouse Lamp Co., (Assignees of Rentschler, H. C., and Merrymon, W. W.). July 20, 1927, [Convention date]. Vacuum tubes.-Gas-filled, alternating-current rectifiers are rendered capable of operation at high voltages, e.g. 200 to 300, by constructing the cathode of a refractory metal, such as molybdenum or tantalum, the anodes of an active metal, such as thorium, uranium or titanium, and employing a gas purifying-agent such as misch metal or other metal of the cerium group. In addition, a deposit of an electropositive metal, such as an alkaline or alkaline earth, is employed on the cathode by coating the anode with a compound of an alkali or alkaline earth in the form of a salt, e.g. barium, calcium, sodium or potassium nitrate, which is gradually reduced to the metal in operation and is deposited on the cathode. The nature of the gas filling is dependent on the voltage employed, helium being used for voltages of 200 to 300 and argon or neon, or mixtures of all three, for lower voltages. In the device shown in Fig. 1, anodes 2, 3 are carried by nickel &c. supporting wires 5 on to which they may be screwed or compressed, the wires 5 being connected to leads 6, 7 and enclosed in highly refractory insulating sleeves 9. Into a recess in each sleeve extends a glass tube 10 fused to the support 8. The cylindrical cathode 4, surrounding the anodes, is supported by wires 12, 13, the wire 12 being connected by a lead 14 to a terminal prong 17, and the leads 6, 7 to prongs 15, 16. Secured to the cathode by a welded strap 20 is a piece of misch metal &c. 19 which is vaporized by high-frequency currents during the exhaustion of the bulb 1 and forms a deposit thereon. A monatomic gas, preferably helium, is used for filling the envelope at a pressure of from 5 to 20 mm., 12 mm. being employed at a voltage of 200 to 300. After completion, the device is seasoned by first passing an alternating current of 220 volts through the bulb 20, Fig. 2, the anodes 2<1>, 3<1> being connected in series with 15 watt, 110 volt tungsten filament lamps 22, 23. The final treatment consists in connecting the anodes to one side of a source 24 of direct current of 400 to 500 volts with the cathode 4<1> connected to the other side through a filter circuit 25 carrying a load 26. This treatment is continued until the anodes reach a bright red-heat and there is no appreciable flashing between them and the cathode at a voltage in excess of that in normal use.

The members 1<a>, 1<b>, Fig. 2, are arranged over bolsters 16, Fig. 3, and a mandrel 7 with inclined grooves 9 and between clamping-jaws 10 all carried by the rods 8, 4 of a slide 5. The jaws are open in the position shown but each is closed by a spring 11 as a punch 15 is advanced by screw-and-nut mechanism 14, link 3 and a frame 19 which is pivoted, at 20 on a rod 4 and operated by a rotating cam 18. At the end of the punching stroke rods 25 push two headless rivets b<1>, carried in shoots 26, into the holes. The cams then move the frames 19 to the left together with the slide 5 and the parts carried thereby which include the bowls 28 and the members 1<a>, 1<b>. The frames 19 are then turned to raise the punches, open the jaws 10, and move them to the right leaving the tube members 1<a>, 1<b> stationary so that the wedge grooves 9 act on the inner ends of the rivets while the members 27 on their fixed pivots d are moved from c<1> to c, Fig. 1, by the bowls 28 slightly upsetting the outer ends. The heads are thus formed in stages and a recess i may be formed in the member 27 to give the correct form to the upper head.

Title: Communication systems
IPC: H04Q3/00
Filed: 1971-04-19
Abstract: 1342781 Interconnection systems WESTERN ELECTRIC CO Inc 19 April 1971 [23 Jan 1970] 20156/71 Heading H4K [Also in Division G4] An interconnection system includes a bidirectional wideband intercom link common to at least three stations and means responsive to selection signals from one of the stations and adapted to exclusively connect that and a selected other station to the link. As described the system is incorporated in a key telephone system. Ten key telephone sets with video equipment each can connect by operation of a corresponding key to any one or more of four common wideband communication lines leading to a wideband exchange and to a common audioonly communication bus over which the calling set can in known manner alert by dial or key signals one or more other stations. In addition each set includes a key which if operated following connection of the set to the audio-only bus but prior to the selection of a further station causes the video transmitter and receiver of the calling station to be connected respectively to transmit and receive pairs of video intercom link and following selection of a called station, the transmitter and receiver of this called station to be respectively connected to the receive and transmit pairs of the video intercom link. Initiation of a further video intercom connection over the same bus by another station is inhibited to ensure an exclusive bidirectional video communication. Further stations can be selected and participate on an audio-only basis. A conference call can also be established between two stations and a further station connected to the wideband exchange. The video connection is in this case still restricted to the calling station and one called party. The calling station can alternate the video connection between the other parties by alternate re-operation of the line keys associated with the audio interconnection bus and the active communication line to the wide band exchange. The line keys of each station have two lamps associated with each of them, a white lamp gives busy and ringing signals for audio only calls and a red lamp is used for video calls. Bell and tone ringers are used respectively for audio-only and video calls. It is stated that all or some of the stations could be replaced by computer terminals and computers.

Title: An improved process for evaporating liquids
IPC: C01B25/234
Filed: 1936-07-21
Abstract: <PICT:0463770/III/1> In a process for evaporating liquids, gases in a warm condition and unsaturated in respect of the constituent to be evaporated are blown below the surface of the liquid under an excess pressure not exceeding that of a 500 mms. water column through nozzles b, the openings of which are at least 5 mms. in diameter.  No heating of the liquid in the evaporation is effected other than by the warm gases and the quantity and temperature of the latter is such that evaporation takes place below the boiling point of the liquid. The hot gases have a temperature below 500 DEG  C and are introduced at speeds of more than 100 metres a minute.  The height of the liquid surface above the nozzle b is maintained between 50 and 400 mms.  The gases passed into the liquid are allowed to impinge against baffles which may be entirely or partially disposed in the liquid or be altogether above the same.  The waste gases pass through a heat-exchanger and preheat the liquid or the fresh gases.

Filed: 1944-10-19
Abstract: 6 0 0,19 8. Compound sheet materials. OHR, W., and UNITY HEATING, Ltd. Oct. 19, 1944, No. 20287. [Class 140] [Also in Groups XI and XXIII] Poorly- or non-conducting surfaces, e.g. of wood, leather or rubber, are bonded by applying a film of hot or cold-setting synthetic resin glue, for example, the phenolic or urea types with acid hardeners, between the surfaces, which may then be clamped together, and heating to effect or accelerate curing of the glue by the passage of an electric current through the glue itself, which is devoid of any added conductive substance. Thus a direct or alternating current, the latter of domestic supply frequencies, is passed through the film between hand- or machine-operated electrodes applied to the glue line at the edge of the surfaces, or if the surfaces are inaccessible or of irregular shape, between electrodes of metal wire or strip embedded and left permanently in the film. The resistance of such glues rises sharply on completion of curing, and the accompanying sharp drop in current, as shown by a meter measuring the current flow through the film, may be used to indicate this stage.

Title: Catalysts for the polymerisation of olefins and process for preparing same
IPC: C08F10/00
Filed: 1956-07-02
Abstract: Catalysts for polymerizing olefines are made by reacting an organic halide with a titanium alloy, preferably aluminium/titanium alloy. The alloy in powder form is ground with an alkyl or aralkyl halide, in an inert atmosphere and below 60 DEG  C.  Alternatively the metal alloy may be introduced as a spray of molten alloy.  Preferably the reaction is stopped before all the alloy is consumed and the reaction product separated from excess alloy and organic halide, using n-heptane as liquid medium. Alloys containing Ti/Al in proportions 1 : 3 are preferred, but this ratio may range 1 : 1 to 1 : 10.  Ethyl chloride and bromide are specified as organic halides.ALSO:A catalyst for polymerizing a -olefines is made by reacting an organic halide with a titanium alloy, preferably aluminium/titanium alloy.

Title: Mechanism for driving a reciprocating pump by a rotary actioned driving unit
IPC: F16H25/00
Filed: 1949-07-22
Abstract: 649,307. Converting rotary into reciprocating motion. ORR, W., A. July 22, 1949, No. 20536/48. [Class 80(i)] Gearing for reciprocating a pump plunger B from a rotary shaft DS comprises a sleeve member A supported for rotary movement and having a helical screw connection P with the plunger B which is guided for longitudinal movement only by a key K. In helical screw connection with the sleeve A is an outer sleeve W which also has a certain amount of axial movement relative thereto. On the opposite side of the driving shaft DS is a rotary shaft H having a sleeve W<SP>1</SP> with a helical screwed connection therewith and a certain amount of relative axial movement. The sleeves W, W<SP>1</SP> are provided each with a gear WG co-operating with upper and lower gears DG respectively on the driving shaft DS and each with a sprocket or pulley SP connected by a crossed chain or belt C. The gears DG each have a sector J removed and re-fitted in a diametrically opposite position. If with the parts in the positions shown the shaft DS is rotated to drive the sleeve W in an anti-clockwise direction the sleeve A is also driven thereby with the sleeve W in its upper position with a consequent downward movement of plunger B. On the gap in the upper gear DG reaching the gear WG this drive ceases and the segment J engages the gear WG of sleeve W<SP>1</SP> which is first displaced to its lower position where it is engaged by the lower gear DG of the driving shaft DS. The gear DG then drives sleeve W<SP>1</SP> and shaft H and, through the chain or belt C, the sleeve W of plunger B in the opposite direction to that previously. This results in the sleeve W moving to its lower position on sleeve A and then rotating the latter with consequent movement of the plunger upwards. When the gap in the lower gear DG reaches the gear WG of sleeve W<SP>1</SP> and the sector J engages the gear WG of sleeve W the drive from sleeve W<SP>1</SP> is stopped and both sleeves are returned to their original positions for the operation to be repeated. The sprockets or pulleys SP can be replaced by gears interconnected by idlers to reverse the directions of rotation and the shaft H could also be adapted for reciprocation as another plunger.

IPC: B62J1/02
Filed: 1924-09-02
Abstract: 242,021. Lycett, E. Sept. 2, 1924. Saddles.-Canvas or other fabric or' like material is blocked to produce articles such as the tops or seats of cycle and like saddles by means of a pair of heated complementary dies having resilient peripheral means for gripping the fabric, the fabric being placed between the dies upon a leather or like sheet which takes the strain, or alternatively, if the fabric has sufficient strength, the leather sheet is dispensed with and additional gripping means are provided. The upper die e, Fig. 1, is attached to a plunger h carrying a plate i from which a ring k is suspended by springs l. The lower die a is provided with a flat peripheral edge b with which the ring k engages to grip the fabric during the operation of the die. An additional spring-pressed block q, Fig. 2, may be employed to grip the fabric for example at the junction of the nose and body in the case of a cycle saddle. Apertures d are provided in the lower die for the escape of air. The leather sheet, which acts as a former, may be treated previously with 'borax and a suitable grease such as Russian fat so that the fabric is stiffened, and imprisoned air flows evenly towards the outer edges of the sheet, thus preventing puckering.
