Title: Improvements in or relating to a sheet stacking and staggering device
IPC: B65H33/08
Filed: 1955-01-06
Abstract: 765,139. Sheet-delivery apparatus. WEAN ENGINEERING CO., Inc. Jan. 6, 1955 [Sept. 30, 1954], No. 393/55. Class 100(1) A sheet-staggering device wherein a vertical pile of sheets is built up of groups of a predetermined number of sheets each group being staggered horizontally with respect to each adjacent group but in vertical alignment with every other group comprises a first fixed front stop co-operating with a first retractable back stop and a second retractable front stop co-operating with a second fixed back stop. The device comprises adjustable side guides 2 which have slots 5 adjacent their rear ends through which the first retractable back stop may project. The first back stop is composed of two portions 13, one for each side guide 2, each operated by an air cylinder 17. The second fixed rear stop 12 is positioned behind the stop portion 13 at sheet length distance from the second retractable front stop 8 which is operated by an air cylinder 11 in a vertical direction. The first fixed front stop 7 is positioned at sheet length distance from the first retractable stop portions 13. Sheets are delivered from a conveyer 6 on to a receiver, which may be automatically lowered in accordance with the height of the pile, located between the front and back stop. In operation a predetermined number of sheets is delivered against the front stop 7 and prevented from bouncing back by the rear stop portions 13 which are in operative position. After the predetermined number of sheets has been counted the cylinders 11 and 17 are automatically operated to lower the front stop 8 into operative position and withdrawn the portion 13 through the slot 5 into inoperative position so that a second similar group of sheets may be delivered against the front stop 8, these sheets being prevented from bouncing back by the back stop 12. After the second group has been delivered the cylinders are again actuated so that the third group of sheets is delivered vertically above the first group, the fourth group being vertically above the second group and so on.

Abstract: 1493838 Tape heater SPETSIAL KONSTRUKT BJURO TRANSNEFTEAVTOMATIKA 6 Jan 1975 [4 Jan 1974 17 June 1974] 405/75 Heading H5H In a flexible band heater comprising resistance heating wires 1 arranged in an insulating base 2 enveloped by a sealed sheath 3 at least one longitudinally extending current supply wire 4 is arranged along the narrower side or sides of the band heater so that the heating of the supply wire(s) 4 by the resitance wires 1 is minimized. As shown, two copper supply wires 4 provided with insulating coating 5 are clipped to the edges of the sealed sheath by longitudinally spaced clips 8 which have projections fitted into complementary longitudinal recesses in the sheath 3 to form a lock joint. The resistance wires 4 are woven, sewn, plaited or embedded in the insulating base which may be made of glass fibre fabric. The sheath 3 is made of silicone rubber. If only one supply wire 4 is provided, the clips 8 are modified to accommodate only the one wire at one narrow side of the sheath. In Figs. 8-11 (not shown) conduits formed integrally with the sheath 3 extend along the narrow sides of the band heater and accommodate the current supply wires. The conduits may be in the form of closed tubes secured to the body of the sheath 3 by spaced webs, or may be longitudinally extending channels whose walls are rolled over to retain the supply wires once they have been introduced. The sealed sheath of this embodiment is made of a material which exhibits residual plastic deformation, e.g. aluminium. Successive heating bands may be electrically connected by junction boxes. The band heater may be used for heating oil pipe-lines or equipment used in conveying food, oils bitumens, low-melting point metals, synthetic resins, mastics and pastes. The heater may be used for heating vessels, containers and chemical reactors. In a pipe-line trace heater, the band heater is secured to the pipe-line by spaced glass fabric band and the pipe-line and heater are covered by thermal insulation protected by a metal casing.

Filed: 1952-01-10
Abstract: 741,356. Cold-cathode tubes. SYLVANIA ELECTRIC PRODUCTS, Inc. Jan. 10, 1952 [Jan. 16, 1951], No. 805/52. Class 39 (1). [Also in Group XL (b)] A T.R., A.T.R. or attenuator tube designed to operate over a predetermined wavelength band comprises a gas-filled section of waveguide 10, Fig. 1, having a window.14b permeable to the waves at at least one end and containing an elongated discharge gap structure consisting of a plurality of discrete discharge gaps spaced apart longitudinally by distances substantially less than one quarter of the minimum wavelength in the band or by a continuous discharge gap of a length at least equal to a quarter of the minimum wavelength, the discharge device being non-resonant over the band. The glass windows 14b are sealed to metal flanges 14a and are resonant at the mid-band frequency. The edge of the window has a metallized band to reduce the Q and so to reduce frequency sensitivity. The upper guide wall has a ridge 16 serving as a common electrode and having one or more conical holes housing one or more keep alive electrodes 24 with glass sheaths 26 and the lower guide wall has a ridge 18 carrying pointed wire electrodes 20 a few 20a of which co-operate with the keep alive electrodes 24. Impedance transformers between the guide ends and the ridged portion may comprise pointed conductors similar to 20 in the guide ends 10a, 10b. The filling is argon and water vapour at a total pressure of 10 mms. In a modification, Figs. 3, 4 (not shown), the ridges 16, 18 are dispensed with and the discharges take place between a plurality of pairs of pointed electrodes. The keepalive electrodes at one potential are enclosed in hollow cones at another potential to maintain ionization within the cones. In a modification opposed pairs of electrodes are mounted on ridges 16, 18. In another form, Fig. 5, the discharge gap is continuous and is formed between blades 46, 48 with sharpened edges. The guide has flared portions at either end to act as impedance transformers. The blades may have to be slightly enlarged in the vicinity of the keep-alive electrodes 54. In another modification, Fig. 7 (not shown), continuous blades are supported on slightly longer continuous ridges to give suitable impedance transformers at the ends. In another form, Fig. 9 (not shown), two sets of point electrodes are interdigitated, the discharges taking place between the points and the adjacent walls. The guide may or may not be ridged as in Fig. 1. Other shapes of guide and modes other than the TE 10  mode may be used. Prior art TR tubes are referred to having single or multiple pointed discharge gaps whose excess capacity is compensated by vanes extending from the sides of the guide (which are equivalent to inductances). The gaps are spaced #/4 apart at the centre frequency of the band and the gap structure is resonant over the band used.

Title: Improvements in process of manufacturing dry rectifiers
IPC: H01L21/16
Filed: 1937-01-11
Abstract: 474,277. Asymmetrically conducting resistances. BARREY, E. Jan. 11, 1937, Nos. 859 and 860. Convention dates, Jan. 16, 1936 and Aug. 27, 1936. [Class 37] Copper elements, oxidized at about 1000 C., are dipped into a conducting medium, at about the same temperature, such as graphite, a fused mineral salt, manganese dioxide or powdered copper oxide. Electric current is then passed through the oxide layers and continued while the conducting medium slowly cools. The current is of the order of several amperes to the square centimetre. This facilitates the crystallization of the oxide layer. After this treatment the black oxide layer is subjected to an electrolytic action and reduced, an iron electrode being placed in contact with the oxide surface. In a modification, the conducting medium may comprise a reducing body and the copper elements are removed from the bath before the red cuprous oxide layer is affected. This layer may then be covered with an electrolytic metal deposit in a bath of a salt of the metal to be deposited by placing the electrodes for example of silver and of zinc in contact with the oxide layer on the same face and applying an alternating voltage.

Title: Mold for continuously casting molten steel
Inventor: MIZOGUCHI TOSHIAKI
IPC: B22D11/00
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To uniformly generate the solidified layer of a cast slab and to surely prevent the occurrence of longitudinal crack without reducing casting speed by forming grooves in which the width and the depth is set in accordance with the viscosity of powder so as to intersect at least a meniscus on the surface at the center part in the width direction of long sides of a mold. SOLUTION: The air having about 1/1000 of thermal conductivity of the powder is infiltrated into the gap part of the grooves 2 in the width direction of the long sides 1 of the mold to form the thin part of the solidified layer and thereby, the longitudinal crack of the cast slab is surely eliminated by dispersing the concentration of stress. That is, the powder is allowed to flow into the grove 2 parts to form the gap parts and also, the air is infiltrated into the gap parts accompanying the flowing of the powder to remarkably reduce the heat conduction from molten steel because the gap parts cool the long sides 1 of the mold, and then, the solidified layer in the groove 12 part is thinned. Therefore, since many grooves 2 are formed in the width direction of the long sides 1 of the mold, the solidified layer is generated at almost uniformity.  The grooves 2 are formed so as to intersect the meniscus within the range from 20mm at the upper part of the meniscus to 50mm at the lower part of the meniscus.

Title: Controlling method for brushless dc motor
Inventor: USHIJIMA NOBUYOSHI
IPC: H02P6/06
Filed: 1990-01-08
Abstract: PURPOSE:To control the rotation of the title motor without employing any rotor position detecting element by a method wherein the supply of current to one phase is limited temporarily for a predetermined period to measure the rise-up condition of the current while the positions of the magnetic poles of the rotor are detected based on the rise-up condition of the current. CONSTITUTION:A rise-up time 58 necessary for the rise-up of the value of current to the specified value of the current becomes minimum when different poles are opposed correctly. Accordingly, the positions of the different poles of the rotor can be judged whether they are opposed correctly by measuring the rise-up time 58. The position of the rotor is detected by measuring the rise-up time 58. When the rotor is arrived at a proper position, a phase, through which driving current is conducted, is switched (commutation) whereby the title motor may be rotated.
