Title: Improvements relating to the pistons of rotary-piston internal combustion engines
IPC: F01C19/04
Filed: 1962-04-24
Abstract: 933,583. Rotary I.C. engines. DAIMLERBENZ A.G. April 24, 1962 [May 31, 1961], No. 15547/62. Class 110 (2). In a rotary internal combustion engine of the Wankel type, a sealing strip 4 is located in an axially extending groove in a lobe of the piston 3 and is urged against the housing inner wall 5 by two springs 7, each acting through a piston 9. The pistons 9 are grooved to accommodate the sealing strip, and extend to the outer surface of the piston 3 so that gas pressure in the working chambers will oppose the action of the springs and, with a sufficiently high pressure in the working chambers, will move the pistons 9 inwardly so that the springs no longer act on the sealing strip. Such movement of the pistons 9 is hydraulically damped by liquid in the chamber 11, which communicates with cooling passages 13 through a small bore 12. The sealing strip is a loose fit in its slot to allow gas pressure to enter the slot and urge the strip against the wall 5. It is stated that the area of the pistons 9 and the stiffness of the springs 7 may be so adjusted that the force with which the strip 4 is pressed against the wall 5 is substantially constant.

Title: Method of and apparatus for detecting a condition incapable of cutting in gas cutting operations
Inventor: SUZUKI ROKU
IPC: B23K7/10
Filed: 1969-03-25
Abstract: 1,241,129. Gas cutting. KOIKE SANSO KOGYO CO. Ltd. 25 March, 1969, No. 15570/69. Heading B3V. A method of detecting a non-cutting condition in a gas cutting operation comprises ejecting a pressurized fluid near a gas nozzle 1 and detecting the back pressure produced as a result of the gas from the nozzle 1 being a non-cutting gas flame or an unignited gas flow. During a normal cutting operation, compressed air is ejected from a jet 2 so that the pressure at a port 6 is equivalent to atmospheric. When the flame spreads out and no longer cuts the work 11, the flame is engaged by the compressed air from the jet 2 causing the air to be heated. A negative pressure is thereby generated at the port 6 causing a pressure switch (9) (Fig. 1, not shown) to be actuated. When the flame is extinguished, a positive pressure is generated at the port 6 causing a pressure switch (10) to be actuated.

Title: Apparatus for producing screws
Inventor: HANNEMAN WALTER MOONEY
IPC: B23G9/00
Filed: 1964-04-15
Abstract: 1,065,083. Screw-making machines. ILLINOIS TOOL WORKS Inc. April 15, 1964, No. 15630/64. Headings B3B, B3K and B3N. [Also in Division B8] A screw-making machine comprises means (106), Fig. 1 (not shown), for intermittently conveying screw blanks (32), Figs. 19 and 20 (not shown), along an arcuate path of travel, a first tool (274) rotating in a first plane to cut bevelled faces (38), (40) on the exposed entering end of each screw, and second rotary tools (386), (388), Fig. 17 (not shown), spaced from the first for rotation in planes parallel to the first plane for cutting slots (42), (44) intersecting the bevelled faces. Threaded blanks pass from a hopper (62) down guides (66), Figs. 3 and 6 (not shown); and are delivered in a horizontal position to a release plate (68). The plate (68) is carried on a leaf spring (74) which is deflected by contact with the turret (106), to enable a screw to drop down, the following screw being retained by pins (92) on a leaf spring (96). Each blank is held between a fixed jaw (108), Fig. 7 (not shown), and a jaw (110) moved to clamping position by a spring-pressed lever (124) and released at the loading station by a fixed cam, (126) engaging the levers (124). Each blank is located axially by its head as it is pressed outwardly by a pin (138), Fig. 8 (not shown), aligned therewith on the turret. Each pin (138) is normally released by a spring (144) but, during the travel of the turret, it is pressed outwardly by a fixed leaf spring (150), Fig. 10 (not shown), to effect the blank location and by an air-operated wedge (154) to hold the blank firmly while being cut by the first tool (274). While being cut by the tools (386), (388), the blanks are held firmly by an arcuate wedge (166) swung by an air-operated rod (170). The turret is indexed by a pawl (202), Fig. 13 (not shown), on a plate (206) oscillated by a crank (212) rotated by a motor (178). The motor also rotates a cam (250) which rocks a segment (242) to oscillate a cam (236) and withdraw spring-pressed locking plungers (232), (234). The cutter (274) is mounted on a rocking bracket (256), Fig. 1, and it, and a flywheel (288) are rotated by a motor (275) driving through chains (278), (284). The bracket is urged towards the turret by a spring (302), Fig. 2 (not shown), and is withdrawn by a cam (306) engaging a wedge (304) which is adjustable vertically to determine the depth of cut. A similar bracket (320), Fig. 6 (not shown), spring (336), and cam (326) are provided for moving the cutters (386), (388) to-and-from the turret. These cutters are also driven by the motor (275) and by a flywheel (352). The cutter shafts (374), (380), Fig. 15 (not shown), are carried on pivoted links which can be adjusted by screws (390), (402) and a wedge bolt (394) to vary the spacing between the cutters. Finished screws are removed by an air blast at a station (406), the air being operated in unison with the clamping means at the cutting stations.

Title: Improvements relating to the controlling of the rotation of rotary bodies rotated byelectric motors
IPC: D06F37/30
Filed: 1930-05-21
Abstract: 355,668. Control of motors. SHAND, S. G., Westwood Works, Peterborough, and BAKER PERKINS, Ltd., Willesden Works, Hythe Road, Willesden, London. May 21, 1930, No. 15685. [Class 38 (iii).] Travelling to predetermined limits.-A control system for a washing-machine includes means for alternately energizing the motor 10 driving the cylinder and applying a brake, by de-energizing a coil 12, so as to bring the cylinder accurately to the load or unload positions. A cycle of operations is briefly as follows. Closure of button 59 causes a motor 91 to turn the water case to the open position, whereupon a switch 107 driven by the case opens the circuit of this motor and prepares the circuit of load button 48, 92. Momentary closure of this button causes energization of relay 46, which by closure of contact 34 maintains itself over a switch 13 driven by the cylinder, and which by closure of contacts 35, 36 causes intermittent energization of main and forward contactors 41, 42 of the motor 10 over contacts on switch 50 driven by the cylinder. The motor thus turns the cylinder in steps until it reaches the load position whereupon the switch 13 interrupts the circuit of relay 46. After loading, button 60 is closed, causing motor 91 to close the water case, whereupon switch 107 opens the circuit of this motor and prepares a circuit of a " start " button 141. Closure of this button energizes a relay 40 which maintains itself at contacts 24, and by closure of contacts 22, 23 energizes the main contactor 41, and the forward and reverse contactors 42, 43 according to the position of a switch 147 continuously driven by a motor 161. After the washing operation is completed, the motor 10 is stopped by opening button 140, and the water case is again opened by closing button 59. Momentary closure of button 49, 93 causes the motor 10 to rotate the cylinder in steps to the unload position. This action is similar to closure of button 48, 92 except that relay 47 and contactor 43 are energized instead of relay 46 and contactor 42. In a modification, Fig. 2 not (shown), the watercase motor is controlled by a single button, momentary closure of which first causes the motor to turn the case to empty the water therefrom and then, after a delay, to turn the case farther into the fully opened position. A subsequent momentary closure of the button causes the motor to reclose the case.

Abstract: 1,140,984. Controlling clutches; variablespeed gearing. DEERE & CO. 7 April, 1967 [8 April, 1966], No. 16013/67. Headings F2D and F2L. The fluid apply pressure of a pedal controlled, e.g. hydraulically applied, clutch at the output side of a variable-speed gear in a motor vehicle, e.g. a tractor, is varied in proportion to the numerical gear ratio (i.e. input to output speed ratio), of the variable-speed gear. As shown, a governed-speed engine 10 drives an infinitelyvariable expanding pulley gear 12 which drives a forward/reverse planetary gear 14, the carrier 44 of which may be clutched to the sun gear 38 by clutch 46 for forward, or braked (not further described), to the casing 50 for reverse. Clutch 46 apply pressure is supplied by a pump P, and modulated by a valve 52 which vents hydraulic pressure between clutch apply line 59 and sump 60. The valve spool 62 is urged to the right by clutch apply pressure fed to the end 72 of the valve via bore 70, and to the left by a compression spring 82 acting between the spool end and a rod 78 connected to the clutch pedal 80, and by feedback pressure 104 in line 102 which includes a restricted orifice 106, the pressure 104 being controlled by a variableorifice valve 88. The spool 96 of valve 88 is positioned by gear lever 32 controlling the gear 12, to vary the orifice 98 and hence vent feedback pressure to sump 94, upshifting the gear increasing the size of orifice 98 to decrease the feedback pressure, and hence lower the clutch apply pressure. Again, Fig. 2 (not shown), clutch apply pressure is vented by variable orifice valve (88a) to a sump directly from the end (72a) of valve (52a), bore (70a) being formed with a restricted orifice (105). The expanding pulley gear may be replaced by a steppedratio gear.

Filed: 1926-06-25
Abstract: 279,529. Hezlet, R. K.., and Highfield, A. June 25, 1926. Explosives.-Nitroglycerine or a nitric ester for gelatinizing nitrocellulose has added to it sufficient alcohol to make it into a good solvent of the nitrocellulose. The invention is applicable to the preparation of blasting gelatine, gelignite, ballistite, and "solventless" cordite. For example, blasting gelatine may be prepared by mixing nitroglycerine with nitrocellulose and then adding thereto 2 to 5 per cent of alcohol. The mixture increases in viscosity so rapidly that if it is allowed to stand in the cold it sets to a jelly in a few minutes. A similar procedure may be adopted for the preparation of gelignite. Stabilizers such as substituted ureas and urethanes may be added and may help the solvent action. Alcohol may also be used as a spray on nitrocellulose powders containing nitroglycerine for colloiding the surface of the powder; some of the nitroglycerine may be mixed with the alcohol for this purpose. Specifications 9361/89, 13486/89, 457/03, and 112,618 are referred to.
