Title: Improvements in and relating to roller bearing races
IPC: B21H1/12
Filed: 1964-12-31
Abstract: 1,096,468. Making roller bearings; rolling. TORRINGTON CO. Dec. 31, 1964 [Jan. 10, 1964], No. 52927/64. Headings B3A and B3M. A roller bearing race is made from a tubular blank by cold working a portion of the blank to reduce the wall thickness thereof and simultaneously increase the circumferential dimension and maintaining the unworked portion at least at approximately the original wall thickness of the blank. The blank 15 is cold worked between an internal roll 65 which is supported by two pairs of rollers 49, 50 and 47, 48 (not shown) and an external roll 46 which is supported by a member 54 and is movable towards and away from the internal roller 65. The internal roller 65 has a working surface 70 which reduces the wall thickness of the blank at 22 and leaves two flanges at the edges of the blank which have the same thickness as the blank. Ridges 71, 72 on the internal roll 65 produce grooves 36, 40 on the bearing and the flanges of the bearing are axially confined between walls 58, 60 on the external roll 46. Roller bearing races of various profiles can be produced by selecting the shapes of the internal and external rolls.

Title: Roll feed and cutting apparatus for use in a photocopy machine
IPC: G03D15/04
Filed: 1970-11-06
Abstract: 1329998 Feeding sheets ADDRESSOGRAPH-MULTIGRAPH CORP 6 Nov 1970 [24 Nov 1969] 52939/70 Heading B8R A sheet feeding device for use with an electrostatic or diazo copying machine comprises means for sensing the length of an original being fed to the machine, means for severing from a supply roll an equal length of copy material and means for superimposing the original and the length of copy material. An original passing along path 102 triggers a switch arm 115 which initiates the feed of copy paper from a roll 30, along feed path 40 towards the point of convergence, 100, of the paths. Release of arm 115 by the trailing edge of the original causes cutter 86 to sever the copy paper. The superposed sheets are fed to the machine by rollers 96, 98. If the original is of such a width that it triggers switch arm 113, wider copy paper is fed, by rollers 72, 74, from roll 32 and no paper is fed from roll 30. If the original is so short that its leading edge does not actuate switch arm 121 before its trailing edge passes switch arm 115, the cutter will not be actuated on detection of the trailing edge by arm 115. Instead the control circuit causes a predetermined length of copy paper ("d" plus "d4") to be severed, thus ensuring that the paper will not be so short as to interfere with the feed. Switch arms 117, 119 detect when copy paper from a particular roll has been used up.

Abstract: 1438679 D.C.-D.C. converters THOMSONBRANDT 20 Nov 1973 [22 Noy 1972] 53854/73 Heading H2F [Also in Division H3] The invention relates to a saw-tooth, deflection current and D.C. supply generator of the type comprising a deflection coil 1 connected in series with a supply capacitor 2 across a bidirectional switch comprising a diode 5 shunted by a thyristor 4, a commutating thyristor and reversely connected diode 12 connected to the first thyristor by a series resonant circuit 6 and a supply inductor 7 provided to charge the resonant circuit. According to the invention additional current is drawn through the diode 5 to assist commutation. It is explained that as a result of this current the diode current falls to zero later in the sweep and the thyristor current not rise to such a high value. Accordingly it can be switched off more quickly and the series tuned commutating circuit current reaches the thyristor current level more quickly allowing a longer time for the thyristor to recover. The additional current is drawn by a resistor 18 or by connecting the capacitor in series with the power supply E (Fig. 5, not shown). In Fig. 6 (not shown) an E.H.T. transformer is connected across the coil 1 and capacitor 20, in series with a large capacitor and a tapping on this transformer is connected by a rectifier to provide a low voltage supply. As shown the rectifier consists of a transistor which is rendered conductive by pulses derived from coil 7, during the steady condition of the voltage across the transformer.

Abstract: 1326105 Pulse modulation circuits CHANDLER EVANS Inc 17 Nov 1970 [25 Nov 1969] 54670/70 Heading H4L In a pulse width demodulator the incoming pulses are limited at 19 and supplied to a switching circuit 20 comprising field effect transistors 28, 30, to the INHIBIT gates 22, 24 and to bistable 26. Assuming bistable 26 to be switched with its output FF positive, field effect transistor 28 will be enabled and due to inverter 32, transistor 30 will be biased off. Thus a signal pulse will be supplied via transister 28 to an integrator 12 so that capacitor C 1  will charge to a potential determined by the input pulse duration. At this time a field effect transistor 36 will be conductive due to an inverter 38 receiving the output FF of the bistable 26 and the charge on a capacitor C 2  of a similar integrator 14, which was charged in accordance with the preceding width modulated pulse, will be supplied to the output line. The trailing edge of the input pulse will switch over the bistable 26 so that transistor 30 is enabled and transistor 28 is blocked. In addition, the gate 24 supplies a positive signal to the base of transistor 40 to clear the integrator 14 in readiness for the next pulse and the transistor 34 conducts to apply the potential across capacitor C 1  to the output line. Capacitor C 2  will be charged via transistor 30 in accordance with the duration of the next input pulse and at the termination of this pulse the bistable 26 will be switched over, gate 22 will supply a signal to cause transistor 42 to conduct and clear the integrator 12 and the cycle will be repeated.
