Title: Improvements in or relating to grooved traverse drums for cross winding machines
IPC: B65H54/50
Filed: 1950-11-15
Abstract: 683,508. Winding machines. REINERS, W. Nov. 15, 1950 [Jan. 7, 1950], No. 27934/50. Class 120(ii) The groove 5 of a traverse drum 2 for a cross winding machine remains shallow for an appreciable distance after each point of reversal o and progressively and continuously deepens towards the point of greatest depth which. is about 120 degrees of arc after the point of reversal. The depth of the groove has also a value approximately equal to its shallowest depth at points shortly before the points of reversal. 6, while the bottom of the groove between its deepest point and the next following point of reversal (or a point shortly before such point) lies substantially in an imaginary plane parallel to but displaced from the axis of rotation of the drum. This arrangement is stated to effect better control of the winding thread F, particularly in the region of the points of reversal of its motion.

Abstract: 845,984. Control of D.C. motors. GAILIS, E. Jan. 3, 1957 [Oct. 4, 1955], No. 28163/55. Class 38 (3). A battery-operated vehicle is started by actuating a push-button to close control switch OS1 which completes the circuit for a first contactor, and also causes capacitor C1 of a timedelay relay device RD1 to discharge whereby relay R1 is de-energized after a predetermined period to close a second control switch OS2. The circuit for a second contactor is thus completed, and capacitor C2 discharged, so that relay R2 closes contacts OS3 after a further period to actuate a third contactor. The delay intervals are adjusted by means of rheostats RH1, RH2. When the push-button is released, the contactors are opened in quick succession due to rectifiers MR1, MR2. Additional footoperated switches may be connected in series with the control switches OS2, OS3, whereby operation of the second and third contactors is also under the control of the driver, Fig. 3 (not shown). The contactors may control tappings in a starting resistance, and the time-delay relays and control switches may be housed in a single casing, Fig. 1 (not shown).

[Class 135] Valves controlled by pilot or relay valves.- A pair of three-way piston valves are arranged side by side in a single casing and are adapted to be actuated by fluid pressure acting on pistons 9 under the control of single beat lift auxiliary valves 7 interconnected by a see - saw lever 25. Pressure from the pressure inlet chamber 21 which is common to both main valves is led to the two actuating chambers 14 through axial passages in the main valves adjusted by screw operated needles 11. The auxiliary valves 7 control communication between the actuating chambers and chambers 15 connected by passages with the main exhaust chamber 22 and are normally held in the raised position in contact with the cover by the escape of fluid through the control passage. In the form shown, the control valves are alternately moved to their closed position by spindles 12 carried by armatures 24 suspended from the see-saw lever 25 and operated by a pair of solenoids 23. The spindles 12 may be operated by means controlled by variations of pressure, electric current, speed or temperature.

Class 72 Iron shot composed of substantially pure iron and having a surface hardness of 60-100 D.P.H. and an interior hardness not less than the surface hardness is produced by heating the shot above 1670F. but below its melting point and maintaining an atmosphere of hydrogen around the shot during heating, holding at the high temperature and cooling. The grain size of the iron, which should not contain more than 0.145 per cent. of impurities may be larger than A.S.T.M. size 2. As shown, the shot may be introduced into a rotary retort 7 having internal flanges for showering the shot and means for maintaining a steady flow of dry hydrogen therethrough, The retort is then rotated by the motor 19. The air in the retort is removed by nitrogen which is in turn replaced by a steady flow of dry hydrogen. The retort is then moved into a furnace 2 at a temperature of 1675-1800F. and held there until the shot has reached the desired hardness and grain size, after which it is withdrawn and allowed to cool while still rotating and being supplied with dry hydrogen.

Title: Improvements relating to electric supply systems
IPC: G03B27/32
Filed: 1928-10-08
Abstract: 326,220. Beaumont, J. H., (Utilities Service, Inc.). Oct. 8, 1928. Supplying consuming devices. - On failure of a main electric supply to a local circuit such as that of exit lamps of theatres, a waterdriven motor 2, Fig. 2, driving an auxiliary generator 3 is started up and the lamps or other consuming devices are switched over to the auxiliary generator. An electromagnet 7, Fig. 6, is permanently connected in shunt to the mains 34. The core 9, on being pulled down by the magnet 7, closes switches 29 to connect the lamps 38 to the mains 34 and also closes a valve 5 for the water supply to the motor 2. When the solenoid is de-energized the core is pulled up by a weight 25 and opens the valve 5 and the switches 29 and closes switches 28 connecting the lamps 36 to the dynamo 3. An auxiliary switch 33, Figs. 6 and 7, is operated when the core 9 is in its lowest position to insert a resistance 35 into the solenoid circuit and so to reduce the normal holding-on current flowing through the solenoid. The stem 18 of the valve 5 is operated by a bell-crank 12 connected by a link 13 to a bell-crank 10. A part 22, Figs. 2 and 7, pivoted to this bell-crank 10 is connected to the core 9 through a compression spring. When the core 9 is pulled down, the valve 5 closes before the switch operating member 31 completes its stroke, the spring being compressed to force the valve against its seat. A pressure gauge indicates the water pressure in the pipe 4 leading from the valve 5 to the waterwheel 2.

A burnishing tool comprises a roller 13 having a frusto-conical periphery and mounted for line engagement with a cylindrical surface 16 of a component 17 to be finished, the roller being slidable along its longitudinal axis XX to vary the effective finished diameter as a result of relative movement of the tool and component axially of the latter. As described, the tool has three rollers 13, each of which is secured by a screw 15 to a spindle 2 mounted for rotation and axial movement in a bore in a housing 1. The axes XX of the spindles lie on a cone having an angle of 15 degrees, and the rollers 13 also have a cone angle of 15 degrees so that their operative surfaces engage the cylindrical projection 16 of a workpiece such as the flange of a universal joint of a vehicle propeller shaft. The inner ends of the spindles have shoulders 11 engaging the outer race of a bearing 18 carried by a stop 20 having a shoulder 23 abutting a mounting member 5 adjustably mounted in a backplate 3. A spring urges the spindles outwardly and as the tool is advanced, the rollers abut the end surface of the workpiece and move inwardly against a spring 24 to engage the surface 16 and reduce it to a size determined by engagement of the shoulder 23 with the member 5. One spindle is displaced from the equiangular position to ensure roundness of the surface 16.

[Also in Division G3] An electrical network which is required to have a variable time constant comprises two or more circuits, having different time constants, all supplied with the same input signal, being arranged to give normally an output only from the circuit of longest time constant and with paths connecting each circuit to the circuit of next longest time constant, these paths being conductive only when the input signal changes sufficiently rapidly. In the Figure the circuits 4, 5, 6 comprising parallel combinations of resistors and capacitors 7, 8 ; 12, 13; 17, 18 are supplied through resistors and diodes 10, 11; 15, 16; 20, 21 from the input 1, 2. Circuit 4 has the shortest time constant and circuit 6, which also gives the output 25, has the longest. When the input voltage changes the output at point 14 of circuit 5 will change more than the output of circuit 6, and if the input changes sufficiently quickly then diode 24 will conduct, forming a path between circuits 5 and 6, and reducing the effective time constant of the whole network. For even more rapid changes of input the path comprising diodes 22 and 23 connecting circuits 4 and 5 also becomes conducting, and the network time constant is further reduced. The circuit is used in the line supplying a D.C. control signal from a measuring instrument to an amplifier in an electromagnetic vibrator control system in which it is desired that the control should have a slow response to slow changes in a parameter and rapid response to rapid changes. The controlled parameter may be peak acceleration or frequency.
