Title: Wheel slide controllers and vehicles incorporating them
IPC: B60L3/10
Filed: 1973-10-02
Abstract: 1431079 Anti-skid brake control WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 2 Oct 1973 [25 Oct 1972] 45871/73 Heading F2F In a vehicle having two bogies each having two axles, the rotational speeds of the axles on each bogie are compared, and a brake release signal generated if, in either bogie, the difference exceeds a predetermined amount, and the speed of the faster axle, if any, of one bogie is compared with that of such an axle of the other bogie, a brake release signal being generated for the slower axle of the two, if the difference exceeds a predetermined amount. A brake valve actuates the brakes for each bogie according to the pressure difference between a brake line and a control reservoir associated with the valve. The supply for the controller is controlled by series switches SK1, SK2 controlled by threshold switches PS1, PS2 respectively taking inputs via OR gates G1, G2 from the highest speed signal of the axles fed through rectifiers GR1, GR2, GR3, GR4 from tachogenerators M1 to M4. Upon the highest speed value attaining an input value #U to the switch PS2, the supply is transmitted to the controller. Since the operation of each valve V1, V2 for release of brakes of each bogie is the same, operation of the valve V1 will be described. D.C. speed signals for each axle of the bogie are compared at a switch DS1 which provides a signal (if the difference exceeds a given amount) to the valve; these signals also pass to an OR gate G11 which transmits the higher signal to one input of a switch DS3, the other input of which being applicable to the other bogie. The switch DS3 provides a signal, if the input difference exceeds a given amount, to the valve for the bogie which provided the lower signal. A bi-stable multivibrator FF1 has a set (A) input actuated by either of acceleration threshold signals of the axles of the bogie from differential threshold switches D1, D3 via an OR gate G7. Thus upon axle acceleration, no output is provided from the multivibrator FF1. Upon a deceleration of either axle attaining a preset value, as indicated by switches D2, D4 (similar to D1, D3), a reset (B) input to the multivibrator FF1 provides a signal to the valve V1 for brake release. This signal is intermittent, since the input to the reset input of FF1 is also fed through a timing delay member Z1 to the set (A) input to cut off the signal. However, a continued input from the switches D2 or D4 allows the reset input to be provided again.

Filed: 1966-10-14
Abstract: 1,157,104. Hydraulic control circuits. BORG-WARNER CORP. Oct.14, 1966 [Nov.1, 1965], No.46060/66. Heading F1P . A constant delivery pump 10 supplies pressurized hydraulic fluid through a duct 28 to a continuously operating variable flow demand hydraulic system A, and a similar pump 14 supplies fluid through a duct 30 and a check valve 36 to the duct 28 when pressure in the latter duct is low, and at or above a predetermined pressure in duct 28, the fluid requirement of system A thereby being satisfied, the pump 14 supplies fluid through a duct 30, a spool valve 32 and a duct 58 connected to an momentarily operated hydraulic system B, assuming a normally open solenoid valve 62 in bypass 60, 66, 50 connected to a return duct 52 being closed; opening of valve 32 so as to connect ducts 30', 58 being effected by partial downward movement of spool 54 against a spring 56 by pressure in duct 28 which when it rises to just above the working pressure of system A is relieved through an orifice 44, a relief valve 46 and ducts 48, 50 to the return duct 52. In operation with both pumps 10, 14 working and assuming flow in duct 28 to be such that pressure therein is below the operating pressure of system A, the whole of the delivery of pump 14 is directed through check valve 36 into duct 28 until when the operating pressure in duct 28 is reached, excess fluid is by-passed to exhaust through orifice 44 and relief valve 46. At this pressure the spool 54 is displaced to connect pump 14 to duct 58 and in the event of a further pressure rise in duct 58 the spool 54 is further displaced so as to connect duct 28 directly to the return duct 52. In a modification the said direct connection of duct 28 to the return line is effected by a separate spool valve. In both embodiments the fluid requirements of system A can be met by pump 14 in the event of pump 10 being inoperative.

Filed: 1973-10-09
Abstract: 1479726 Soldering METAL BOX Ltd 4 Oct 1974 [9 Oot 1973] 47151/73 Heading B3R In soldering a seam on a body, the body is advanced past an orifice, a continuous solder wire is fed towards a solder wire melting means, wherein the wire is melted in a cavity thereof and the melted solder is caused to be directed as a jet through the orifice, the melted solder being urged through the orifice substantially solely by the pressure exerted on the melted solder in the cavity by the wire being advanced intermittently to the melting means. A solder wire 2 is, in an embodiment, drawn from a spool 15 Fig. 1 and fed intermittently by a reciprocating gripper feed device 4 operated by a cam driven from the main drive shaft 26 to a solder wire melting block 3 while can bodies formed in a unit 22 and fluxed are fed along a support 17 in synchronism with the feed of the solder wire over the block 3. The block 3 is electrically heated by heaters 23 and controlled by thermocouple 24 and the wire is fed into it through a nozzle 19 Fig. 4 to a cylindrical cavity 11. The forward motion of the wire maintains a sufficient pressure to cause the molten solder to issue as a jet from the orifice 12 to the internal seam of the can, back flow of molten solder from the cavity being obviated by the chilling effect of cold solder wire in the nozzle 19. The can bodies may be rectangular or cylindrical and the solder jet may be supplied externally to the can body. The can body side seam may be heated before and/or after the application of the solder thereto.

Title: Pneumatic impact tool
IPC: B25D9/14
Filed: 1962-12-14
Abstract: 1,005,018. Percussive drills. SKIL CORPORATION. Dec. 14, 1962 [Sept. 11, 1962], No. 47239/62. Heading B4C. A pneumatic impact tool 10 comprises a barrel 22 having a chamber 23 in which a hammer piston 30 is adapted to strike the shank 28 of a tool bit 29, the tool having passageways 20, 50 for directing air from a pressure source to a pressureactuated valve 55, of a lightweight non-metallic material arranged to control the flow of air to opposite ends of the chamber via passages 48, 35, 37 in order to reciprocate the piston. The barrel 22 is screwed into a handle portion 11, a valve body 40 being clamped thereby so as to define an annular chamber 41 communicating, via a passage 20 and a valve 17, with a chamber 14 fed with compressed air. The valve body is formed with a spigot portion 43 in which a groove 46 is cut in order to accommodate a valve member 55 made from a canvas or linen base impregnated with resin; the groove communicates with the chamber 41 via grooves 53 formed in the end surface of the barrel. In operation, upon opening the valve 17 air is fed via passage 20, chamber 41, grooves 53, groove 46 and a port 48 into the rear end of the chamber 23 thereby driving the piston forward. After a certain travel of the piston an exhaust port 32 is closed, the air trapped in front of the piston being compressed until the latter strikes the shank 28. The compressed air in front of the piston acts, via the passage 37, 35 and 50, on the valve member 55 thereby moving it to close off the port 48 and thus allow the air from the groove 46 to flow via passages 50 and 36, 37 into the front end of the chamber to reverse the piston the air in the rear end of the chamber being exhausted via a port 33. In order to form the port 37, a hole is drilled through the wall of the barrel until the drill breaks into the passage 35, this operation thereby simultaneously producing the exhaust port 32. Specification 1,005,019 is referred to.

Filed: 1972-10-13
Abstract: 1399256 Photo-electric edge detector E SICK 13 Oct 1972 [22 Oct 1971] 47365/72 Heading GIA The exact detection of the passage of an edge, between two contrasting areas 11, 12, as it passes across the field of view of photo-electric apparatus. is provided by summing the outputs of two detectors viewing zones 15', 16', respectively wholly within the contrasting areas, and subtracting therefrom twice the value of the output from a detector viewing central zone 14', the resultant signal being compared in a threshold device with a reference level 4 to provide a switching signal. In the arrangement of Fig. 2 besides the abovementioned calculation carried out on the detector outputs by computing amplifier 17, the difference between the outputs of detectors 15, 14 is determined by amplifier 19, to obtain information as to whether the transition is from light to dark or dark to light. The threshold levels (k 2 , k 3 ), which must be above k 1 , may be set individually. One type of transition may be detected at any one time by suitable positioning of switch 28 coupling to AND gate 22. If the type of transition is irrelevant, instead of switch 28 an OR gate is used. In Fig. 7, AND gates 23, 24 and flip-flop 25 are used to give indications at 26, 27 of when transitions in the respective directions occur. The threshold value k 1  of comparator 18 may be varied in accordance with variations in lamp intensity as sensed by a further photo-cell. Alternatively, the amplifier 17 may be adjusted.

Abstract: 1403163 Latches APPLIED POWER Inc 11 Oct 1973 [11 Oct 1972] 47586/73 Heading E2A  A latching assembly for releasably latching a tilt cab of a vehicle to a chassis comprises a restraining member consisting of a pair of L-shaped spring lees 50 movable towards and away from a keeper pin 24 and biassed by a spring 80 away from the pin, a cam plate 48 pivotally connected to the legs by a pivot pin 64 and having a hook member 46 for latching engagement with the pin, the cam plate having an abutment 58 laterally offset from a path of travel of the pivot pin, a cam guide 40 for engagement with cam surface 61, 62 on the plate 48 and a ram 74 movable towards the pin to apply force to the abutment to translate and to impart a rotary bias to the plate and thereby effect engagement of the cam surfaces with the guide, the first surface 61 guiding the plate to move the hook member linearly out of engagement with the pin and the second surface 62 allowing the cam plate to pivot and thereby move the hook laterally out of the path of the pin. The latch assembly is supported by a mounting plate 26 and a supporting plate 28 interconnected by side plates 30. The hook member 46 is biassed by springs 134 towards a latching position and should the hook member be in latching position before engaging the pin, the hook member is moved to disengaging position by the pin striking an inclined surface 138 of the hook member after which the hook member engages the pin under the bias of the spring. The ram 74 moves in a cylinder 68 and may be biassed upwardly by a spring 108 whereby when the hook member is lifted when the chassis rises the ram remains in engagement with the plate. The return movement of the ram may be retarded by a non return ball valve 116 in one fluid inlet for the ram the other inlet being adjustable by a screw 124. The hook may pivotally support a bracket 140 the upper edges of which abut beneath the pin preventing the pin from sliding down an inclined edge 47 of the hook member and so effects return movement of the hook member. The bracket acts as a safety latching device and is moved anti clockwise against the action of the springs 134 before release of the pin is effected by supplying fluid to the ram. A light signal may indicate when the latches are operative by the spring arms closing a switch 125 in a circuit for a lamp 128 or a pressure switch 132 may respond to increased pressure in the hydraulic circuit or the hook member may operate a switch to close the circuit.
