Title: Airline lubricator
Inventor: RISKE GILBERT
IPC: F16N7/34
Filed: 1964-08-27
Abstract: 1,083,701. Lubricators. PARKER-HANNIFIN CORPORATION. Aug. 27, 1964, No. 35181/64. Heading F2A. An airline lubricator has one of its parts reversible so that the air-inlet becomes the airoutlet and vice versa whereby the lubricator may be rotated 180 degrees to bring a filler open. ing for the lubricant to an accessible position- The lubricator comprises a body (10), Fig. 1 (not shown), having an air-passage (11) therethrough with an inlet (12), an inlet section (13), an outlet port (14), an outlet section (15) and a valve-chamber (16); and a reservoir (19) which is attached to the body (10) by a collar (21) and lock-ring (33). A cap (41), having a central bore (42) therethrough and chambers (43, 44) therein, is attached by screws (30), Fig. 3 (not shown), to the body (10). A hub (45), Fig. 1 (not shown), of the cap is received by a central recess (55) in the body (10) and the bore (42) of the cap is in alignment with a central bore (81) in the body (10). The valve-chamber (16 receives a rotary-valve (70) therein which has slots (71, 72), Fig. 6 (not shown), a central bore (96), Fig. 1 (not shown), radial slots (99) and a bushing (101) mounted therein. The latter is threaded internally and receives a needle-valve (102) therein. In operation, pressurized air enters the inlet (12) and passes through slots (71, 72) of the valve (70) to the outlet (14). A portion of the air passes through openings (51, 52) in the body (10) and into the chamber (43) from where it passes via a slot (50), a chamber (56), a passage (57), Fig. 2 (not shown), a recess (58), valve (60), clearance (63) and passage (64) to the reservoir (19) for pressurizing the lubricant therein. The pressurized lubricant passes up a tube (90), through a ballvalve (95), through the bore (96), Fig. 1 (not shown), and through the needle-valve (102) to the radial slots (99) which open into a chamber (77) from where it flows through passages (46, 47) and into the chamber (44), from where it connects, via openings (54, 53), to the outletsection (15). Thus the lubricant is entrained with the air which passes through the outlet (14), this being effected when the filler opening (59) is positioned as in Fig. 3 (not shown), and the inlet (12) is at the left-hand side. If, however, the filler opening (59) is not readily accessible and it is desirable to rotate the body (10) through 180 degrees, so that the filler opening (59) is now positioned as in Fig. 7 (not shown), with the inlet (12) at the right-hand side, then the direction of air-flow would have to be from right to left. However, to prevent alteration to the piping layout the cap (41) is reversed, an arrow (31) being provided to indicate the direction of flow. Thus, the chamber (43), Fig. 1 (not shown), becomes aligned with the opening (54), chamber (44) is aligned with the opening (52) and the slot (50) is aligned with a portion (56c) of chamber (56) so that inlet is now at (14) and the outlet is now at (12).

Filed: 1968-07-24
Abstract: 1,170,410. Electric model railways. M. ERNST. 24 July, 1968 [25 July, 1967], No. 35214/68. Heading A6S. Means for running two toy electric trains automatically in block section operation are characterised in that there is preceding each block section an isolated section, which is normally isolated from the traction voltage and which is sufficiently long for a train arriving on it at full speed to come to a halt before the end of it, each isolating section being able to be connected to the traction voltage through a contactless electronic switch having a control electrode connected` through a resistor to the preceding isolated section and also, in the case where there are more than three block sections, to the next but one isolated section, the resistor being such that when a locomotive is standing on an isolated section connected to the control electrode, the control current flowing through the motor windings of the locomotive to the electrode is sufficient to switch on the electronic switch but is not sufficient to cause actuation of the motor of the locomotive. The electronic switches are preferably transistors. Each block section may be provided at its beginning with a signalling device which is operated by contactless switches and has a red and a green light. The lights are provided by filament bulbs connected to a transistorised monostable multivibrator, the red bulb being in the stable branch and the green in the unstable branch. The signal immediately following one isolated section is changed from red to green by a train standing on the preceding isolated section which allows a control current to pass through the motor windings of the train, then through a resistor, to the multivibrator. An override switch may be provided which causes all the isolated sections to be connected to the traction power and all the signals to be red.

Abstract: 404,799. Statistical apparatus. NAAMLOOZE VENNOOTSCHAP KAMATEC, 29, Rokin, Amsterdam. Dec. 13, 1932, No. 35351. Convention date, Feb. 5. [Class 106 (i).] Sorting cards.-Relates to a machine for sorting punched record cards or the like and may be applied to machines of the type described in Specification 295,353, [Class 106 (i), Calculating &c.]. Deflector-actuating means are guided by the card-reading into one of a number of channels of different lengths and at the end of the channel actuate mechanism to raise a card deflector at the time the corresponding card reaches the deflector, the deflectoractuating means consisting of independent bodies (steel balls 4) which move at a speed proportional to the card-feed. The balls 4, fed up path 7 by vane 8, fall under gravity down the channels 3 formed by ribs 2 and close contacts 5 which actuate the corresponding deflector magnets. When a card hole is read, the corresponding magnet 18 is energized and through its armature and a rod 19, pushes a ball from groove 6 into the corresponding channel 3. The ball falls intermittently down channel 3; alternate bars with interceptor pieces 10 are attached to a bar 12 and intermediate interceptor pieces are attached to a bar 13. Bars 12 and 13 are pulled together by springs 14 on to two flats on each of two rollers 15. Those rollers are oscillated by links 16 and a bar 17 which reciprocates regularly whilst the machine is in operation so that the two sets of interceptor pieces 10 attached to bars 12 and 13 are alternately withdrawn from, and replaced in, channels 3 in alternation with each other. By these means a ball in any channel falls from one intercepter piece 10 to the next below, until it reaches its contacts 5. The cards may be read by mechanical means. The balls may be fed along the channels by conveyer worms and the channels may be in line with each other instead of side by side ; or the channels may be circular. Further, the channels may be of the same length, the means for actuating the deflector and the ball speed being correlated to give the correct timing in each case.

Filed: 1929-11-25
Abstract: 343,928. Coil - winding machines. POSTLACK, R., 16, Schlosstrasse, Steglitz, and ZETLAND, M., 18, Budapesterstrasse, both in Berlin. Nov. 25, 1929, No. 36066. [Class 120 (ii).] In a machine for winding arcuate bobbins, particularly bobbins or core segments of inductance coils, a rotating shaft H has fastened to it a discshaped carrier G on which are fixed one or more pins L carrying reels J of wire. Each pin L has a coned collar L1 against which a loose coned ring M is pressed by a spring N. A disc O, engaging the reel J by a pin O1, is connected to the ring M by means of a spiral spring P, so that tension is applied to the wire by the friction between the ring M and the collar L1. The wire K1 runs through an eye in a guide Q, adjustable on the carrier G, to the arcuate bobbin C to be wound. This is clamped on an arcuate mandrel R between a pin R1 and an adjustable flange R2. The mandrel R is carried by a swinging arm S having a handle Sl and carrying a slide S2 which moves in an arcuate guide T mounted on a movable table U. The bobbin may thus be adjusted so that the plane of each turn as it is wound is at right-angles to the axis of the shaft H. The carrier G or the table U may be mounted on a rotating or traversing part of a lathe, milling machine, or other machine tool.

Abstract: 783,393. Door fastenings. GENERAL ELECTRIC CO. Dec.16, 1955 [Dec. 22, 1954], No. 36119/55. Class 44 A magnetic latch for holding a door member 3 engaged with a cabinet member 4 includes co-operating permanent magnet and armature elements 7, 8 positioned opposite each other on said members and comprises a structure mounted on one of the members for supporting the associated one of the elements thereon, the structure including an adjustable supporting member 19 having a tapered portion 22, means mounting the said one element on the supporting member with the element being movable therealong, a spring 26 biasing the element against the tapered portion of the supporting member, thereby resiliently to hold the element in a normal position, the element being movable against a spring to cushion the impact as the door member is closed and being adapted to swivel on the tapered portion to correct for misalignment of the cabinet member and the door member and means 20 for adjusting the position of the supporting member relative to the face of the said one member thereby to adjust the normal position of the element to allow for variations in the closed position of the door member relative to the cabinet member. The magnet 1 is attached by means of a clip 15 to a non-magnetic supporting member 11 which is bolted to the cabinet member 4. The magnet element is recessed behind the outer face of the cabinet member adjacent an aperture 18 so that the outer wall of the cabinet acts as a shield when the door is open to minimize stray flux from the magnet element. The armature element is of U- shape with a long bight 9 and short legs 10 which extend outwardly towards the magnet element. It is provided with a central aperture in the bight 9 through which the supporting member 19 passes. The supporting member 19 is a screw the stem of which has a threaded portion forming the means for adjusting its position in conjunction with a threaded socket in a plate 23 which is secured to the door member 3. The tapered portion 22 joins the head of the screw to its stem and the portion of the armature aperture engaged by the tapered portion is rounded so that the armature element can swivel. The swivelling action of the armature element is limited by means of a guide member 27 which has a large recess 28 into which the armature element can move against the pressure of the spring 26. The back of the recess in addition to limiting the swivelling of the armature element can also, if necessary, limit the inward movement of the armature element during the closing of the door member. The recess 28 also serves to prevent rotation of the armature element about the screw 19. The screw 19 is prevented from turning except when adjustment is necessary by providing it with a tab 32 which fits into an offset portion 33 of a recess 31 in the armature element which contains the head of the screw 19. Thus to turn the screw the armature element must be depressed manually against the pressure of the spring 19 so that the tab 32 is clear of the portion 33.
