Title: Arrangement for indicating the level of oil in the crankcase of a motor-car and the like vehicle engine
IPC: G01F23/60
Filed: 1950-10-11
Abstract: 673,624. Electric indicating systems. LAURY, H. Oct. 11, 1950. [March 21, 1950 ; May 23, 1950]. No. 24842/50. Class 40 (i). [Also in Groups XVIII and XXVII] The oil level in a vehicle engine crankcase is measured in an auxiliary container connected by a pipe at the centre of gravity of the crankcase, the pipe having connections to reduce the surge of oil in the crankcase. The level is indicated on a suitably graduated ammeter 27 which measures the current passing through a variable resistance circuit, the resistance of the coil 15 being varied by contact wheels 22 coupled by a rod 12 to a float 11 in the auxiliary oil container 10 coupled by a pipe 9 to the crankcase at the drain hole. An alarm signal 29 is given when the oil level becomes too low operated by the wheel 22 dropping to make contact with a plate 24 let into the bottom of one of the vertical slots 17 which guide the wheels 22. The wheels 22 are. carried by a resilient fork 21. In Fig. 2 (not shown) the oil float is in a chamber cast on the side of a cast crankcase and connected by a pipe to the crankcase. In Fig. 3, a knurled wheel 55 connected to the float 53 tilts a bellcrank lever 57 carrying spring contacts 59 moving over an arcuate resistance coil 60 to affect the reading on the ammeter 65. An adjustable screwed stop 63 coupled by a spring 62 to 57 allows initial adjustment of the resistance and thus of the ammeter reading. In Fig. 4, the float 71 in one compartment 69 pivots a bellcrank lever 73 to 76 in the other compartment about 75 whereby contacts 77 move over the resistance 78. When the oil level falls too low, a contact 82 on the float completes a circuit through 83, 84 to operate an alarm lamp on the dashboard of a car.

Abstract: 735,219. Rotary duplicating machines. RITZERFELD, W., and RITZERFELD, G. Feb. 10, 1950, No. 24945/54. Divided out of 735,181. Classes 100 (1) and 100 (2). In a rotary duplicating machine having a printing drum 550 carrying a master sheet, and an impression roller 551 co-operating therewith, and in which the impression roller is moved into contact with the drum by means operated from the drum to effect duplicating of at least part of the master on to a copy sheet and is tripped to interrupt the duplicating, a sheetfeeding device is provided for moving the copy sheet into position between the drum 550 and roller 551 for printing the text portion while the impression roller is tripped and the printing drum is at rest. Prior to the machine being set in motion, the copy sheet is placed by hand with its front edge adjacent to the line of contact of the impression roller 551 with a spring-pressed roller 552, the roller 551 being in its tripped position. The roller 551 is then rotated manually by a knob on a spindle 556 having fixed thereto a toothed wheel 557 carrying a pawl 558 engaging a ratchet-wheel 559 which is free on the spindle. The ratchetwheel is connected to the impression roller 551 by a chain 561 and toothed gearing 562 ... 565, so that when the wheel 557 is turned anticlockwise by the knob, the pawl 558 rotates the wheel 559 and causes the roller 551 to be rotated so as to feed the copy sheet. A wheel 566 geared to the wheel 557 carries markings corresponding to lines on the copy sheet so as to indicate the amount by which the sheet is fed. The knob, when released, is returned by a spring 568 to its initial position together with the wheels 557, 566, during which movement the pawl 558 rides over the wheel 559 without rotating it. The movement of the impression roller away from and into contact with the printing drum, and the operation of the moistening device is controlled by a set of cams as described in Specification 735,181 with reference to Fig. 4 thereof.

Abstract: 1,224,543. Punching. FEINTOOL A.G. 27 May, 1968 [5 June, 1967], No. 25280/68. Heading B3W. A fine punching device comprises a stationary die 4 with a counter punch 7 mounted in the die opening 6 and a punch 19 which extends through a contact plate 14 formed with a ring of teeth 17 and mounted in a reciprocable punch table, the cutting edge 12 around the die opening 6 being substantially convex, Fig. 3. Instead of a curve the cutting edge may comprise three faceted faces in planes (23), (24) and (25), Fig. 2 (not shown). In use, the punch table is moved upwardly with a workpiece between the die 4 and contact plate 14, the counter-punch 7 being first pushed into the die opening 6 until its surface 21 is level with the die surface 8. The workpiece is then clamped between the die and the plate 14, the teeth 17 penetrating the workpiece to prevent its displacement during simultaneous upward movement of punch 19 and counterpunch 7. The blank thus formed, which is said to have a smooth edge, remains in the die opening 6 when the punch 19 is lowered and is ejected by the counterpunch 7. The die 4 is preferably formed of hard porous metal, e.g. sintered or cemented carbides and lubricant fed to the die opening 6 and cutting edge 12 forms a deposit in the pores which helps to retain a film of lubricant between the die 4 and the workpiece during punching.

Title: Improvements in or relating to thread guides for spinning man-made filament yarns
Inventor: TURNER ROWLAND SPENCER
IPC: D01D5/00
Filed: 1958-08-09
Abstract: A convergence thread guide for use in spinning artificial threads comprises an upper and a lower guiding portion, the upper portion being moveable relative to the lower portion and the mutual arrangement of the two portions being such that, when they are both in their normal operating positions, the filaments are in contact with the upper portion only and that, when the upper portion has been moved relative to the lower portion, the filaments are in contact with the <PICT:0855023/IV(a)/1> <PICT:0855023/IV(a)/2> latter only. As shown, the moveable guiding portion 1 of a convergence guide comprises a brass arm 3 pivoted at 5 and provided with three fixed pins 15, 17, 171 of hard-wearing refractory material forming three sides of a rectangle between which the filaments are converged to form a yarn.  The stationary guiding portion 7 comprises a brass annular member 9 fitting within an outer metal ring 11 at the top of a steam conditioner tube 13.  Three hard pins 19, 21, 211 are secured within the annular member 9 so as to comprise three sides of the hole through which the filaments pass on their way, as yarn, into the conditioner tube 13.  When the pivoted arm 3 is in the normal operating position it is horizontal and lies flat across the top of the outer ring 11, and its length in relation to the position of the annular member 9 is such that the three pins 15, 17, 171 are all fractionally within the three pins 19, 21, 211 of the member 9 when viewed from above (Fig. 1).  Thus, during spinning, the filaments make contact with pins 15, 17, 171 only.  When these pins after a period of use become dirty, the arm 3 is pivoted backwards (as shown in chain-dotted lines in Fig. 2) so as to withdraw it from contact with the filaments, which then run in contact with the pins 19, 21, 211.  While in the withdrawn position, the pins 15, 17, 171 may be changed or cleaned in situ, and the arm then lowered again into the operating position without interruption of spinning.  The guide is applicable both to melt spinning and to the spinning of spinning solutions.
