Title: Coating machine spindle
IPC: B05C19/00
Filed: 1965-09-28
Abstract: 1,057,410. Coating apparatus. POSSIS MACHINE CORPORATION. Sept. 28, 1965 [Oct. 21, 1964], No. 41204/65. Heading B2L. [Also in Division F2] In a machine for coating with thermosetting resin selected portions of a workpiece 14, e.g. an electrical machine coil supporting stator core, wherein it is desired to avoid a buildup of resinous coating on the workpiece supporting spindle and to exclude resinous coating from portions of the workpiece, the heated workpiece is supported by a rotary spindle comprising an outer annular casing 66 surrounding a cooling chamber 68 through which liquid coolant is circulated, the casing 66 being fed by air under pressure and the outer surface of the casing having air egress slots 86 arranged opposite the stator-pole pieces so that exhausted air physically deflects resin powder away from the pole piece edges and adiabetically expands to cool the spindle and adjacent workpiece surfaces to a temperature below resin thermosetting temperature. Air is supplied to the slots 86 from a central conduit 40 in a supporting shaft 10 through an opening controlled by a screw 84 to control air flow rate as required, recesses 82, 80, and circumferentially spaced outer casing ducts 78. Liquid coolant is supplied to the chamber 68 through a shaft conduit 42 and an inlet 70 and is discharged through an outlet 72 and a shaft conduit 44. Parallel elements 74 fixed within the chamber 68 disperse coolant and ensure uniform distribution. A small clearance exists between the outer surface of the casing 66 and the workpiece. Keys, staked to the outer surface of the casing 66, align the stator core on the spindle and their slight protrusions between the pole pieces act as physical masking means and air flow baffles to prevent the deposit of resinous powder on the pole piece peripheral edges. A spindle assembly selected to suit the stator core is secured on the shaft 10 by a nut 132. A plurality of spindles may each be rotatably mounted on a rotatable table indexable to sequentially advance the spindle assemblies to resin powder nozzles. Each spindle is rotatable with respect to the nozzles and the table by a lever arm which is retained in a given position, during table indexing, by a detent. Air and liquid conduits feed to and discharge from a stationary table support, from whence air and liquid communicate with the spindles through a central rotary union, radially disposed hoses and further rotary unions.

[Also in Division H1] A photo-electric device comprises an insulating base 12, a body of semi-conductor material 16, 18 having a PN junction 22 therein and a plurality of spaced crystals 20 which are transparent at least to a particular wavelength of incident radiation. The "depth" of the crystals is equal to or greater than the wavelength. It is stated that the crystals act in effect as optical wave guides whereby the standing wave pattern of electromagnetic radiation set up in the guides when these are exposed to incident radiation influences the adjacent semi-conductor material and thus inhibits or enhances the flow of electrons across the junction in dependence upon the position of the positive node of the standing wave (Fig. III not shown), thereby producing in effect half-wave rectification. Full-wave rectification is obtained if a NPPN structure is used around the crystals and appropriate electrical connections are made to the layers. If the crystals are of silicon, the device serves as a detector of radiation having a wavelength of 0.7 microns.

Abstract: 1318469 Phonograph record selection circuits SEEBURG CORP OF DELAWARE 9 Sept 1970 [11 Sept 1969] 43076/70 Heading G4H A method of selecting a particular record selection in a phonograph comprises generating a group of characters which identify the selection, encoding and storing the characters until all the characters have been selected and stored, transmitting the coded characters to a second store and decoding the characters after all the characters have been received and stored. The method is used in record selection apparatus which is provided with a keyboard of switches, the sequential depression of three of which selects a record in a control record playing apparatus. After inserting appropriate coins, each digit of a three digit decimal number corresponding to the selected record is encoded in binary form by actuating the respective keyboard switches. Each switch when operated marks one or two of four output leads with a pulse provided by a power source connected to each lead via a resistor. The operated switch earths the respective lead via a transistor switched on by the insertion of the appropriate coins. The binary coded digits are fed to a first shift register which is clocked by pulses from a circuit connected to a switch ganged to the keyboard switches. When this register is full its contents are transmitted to a second register the outputs of which are fed to a decoder comprising a number of NOR gates. The decoder provides control currents for a memory circuit in the record playing apparatus.
