Title: Improvements in or relating to immersing and centrifuging units
IPC: B05C3/08
Filed: 1945-10-31
Abstract: 615,904. Centrifugal machines. RONCI, F. M. Oct. 31, 1945, No. 28856. [Class 23] Small articles are placed in a basket separator 123 which is then secured in place on a rotor 120. A container 58, half full of liquid, which stands on a hydraulically operated table 60, is raised to its top position so as to immerse the basket in the liquid. The container is then lowered to a position in which the basket is out of the liquid but still within the upper part of the container. With the parts in this position, the basket is spun and to complete the removal of excess liquid the rotation of the basket is reversed. The container is then moved to its lowest position and the basket can be detached from the rotor and removed. The apparatus is enclosed in a casing 22 provided with a hinged door 80 which is opened for the removal of the container 58 and the door has a vertically sliding panel 68, which can be lowered into the position shown for the removal of the basket. The casing parts are held together by two rods 30 which also provide guidance for the table 60. The rotor is driven by a reversible electric motor 158 through a belt-gear and the controlling handle 128 applies a brake to the rotor when in its neutral or stop position. A flared guide 186 moving with the table 60, when the latter is in its top position, engages a pin 166 on the spindle of the controlling handle and ensures that the motor is stopped when the basket is immersed. The table 60 has a lug 108 which engages a part of the panel 68 and lifts the panel to its closed position where it is held by a spring latch 90. U.S.A. Specifications 2,102,819 and 2,387,300 are referred to.

Title: Method and apparatus for fabricating laminated structural panels
IPC: B31D3/00
Filed: 1972-06-20
Abstract: 1371451 Making laminated panels WESTVACO CORP 20 June 1972 [22 July 1971] 28864/72 Heading B5N Structural panels are made from lengths L of material having a major strength plane and direction (e.g. double faced corrugated board, in which said direction is parallel with the corrugation axes and said plane is the plane of the board) by conveying them parallel to said plane and perpendicular to said direction, severing each length to form a series of strips 74, conveying the strips in a second direction (indicated by an arrow in Fig. 2) and applying adhesive to the exposed faces of selected strips, depositing the strips (see Fig. 3) in face-to-face juxtaposition on to a planar surface and conveying them therealong in a direction perpendicular to the major strength direction, and compressing the series of strips The double-faced corrugated board may be of paperboard, steel or aluminium and is produced as a continuous sheet by conventional means and is sliced into lengths L by a rotary cutter. The lengths are fed by gravity into a feed hopper from which they are forwarded singly for cutting (see Fig. 1, not shown). As shown (Fig. 2), the lengths are cut into strips 74 by a saw, jet or laser 22. Each group 75 of strips passes to a direction-changing station 30 equipped with two sets of conveyer lines 31a, 31b having lugs 32a/33a, 32b/33b for engaging the rear face of a strip group, and is forwarded to a conveyer 37 (Fig. 3). The forwarding of the groups 75 may be electrically co-ordinated with the forwarding of the lengths through the cutter and the operation of a restraining gate 25 (see Fig. 5, not shown). The line of strips 76 is directed on to a collimating table 44 by dogs 39a, 39b on the conveyer sheave and is pushed forward by an oscillating trip-hammer 42 which strikes each strip. Adhesive is applied to the strips by an applicator 100, but is omitted from strips 74a, 74b to enable production of a series of cores 77. Suitable adhesives are specified. The motion of the trip-hammer 42 may be rectified (to overcome the resilience of the board material) by providing a weighted strip 45 of a soft amorphous elastomer or a pile fabric brush, which also assists setting of the adhesive, and induces compressive forces in the series of strips and may be electrically co-ordinated (see Fig. 6, not shown) with the adhesive applicator 100 so that adhesive is omitted after application to a predetermined number of strips. The cores 77 may be faced with lengths 78a, 78b of double-faced corrugated board by adhesive.

Title: Electrophotographic reproduction
IPC: G03G17/02
Filed: 1964-07-15
Abstract: 1,018,290. Electrophotographic apparatus; exposure control. EASTMAN KODAK CO. July 15, 1964 [July 15, 1963], No. 29066/64. Heading G2H. In an electrophotographic printing apparatus, a uniformly charged photoconductive layer 15, such as zinc oxide in resin on a paper base, is exposed to an electromagnetic radiation image and the average electric field produced by the charged layer during exposure is continuously measured and the exposure is terminated when this field has changed by a predetermined amount. An electrometer is used to measure the electric field and, until exposure commences, the field-sensing electrode 25 is either earthed or shielded by metal shield 31 from the charged layer 15. The electrometer signal is rendered intermittent by rotating seater 26 and is amplified at 36, the output across resistor 37 being fed to the grid of pentode valve 40 whose screen grid is voltage stabilized. The anode voltage at valve 40 controls the grid of triode 43 through Zener diode 42, relay coil 20 being actuated by the triode. When shield 31 is removed, manually or mechanically, the increase in the electrometer signal causes triode 43 to conduct and switch 19 is closed by coil 20 to start exposure by lamp 10 using transparency 11 and lens 12. The light from lamp 10 which may provide infra-reds or ultra-violet, and visible light causes a steady decrease in the field due to layer 15 until the anode potential of valve 40 fall to a level at which triode 43 cuts off; the switch 19 is then opened. The opening and closing of switch 19 may be manual in response to the reading of a milliammeter displaying the electrometer signal. An alternative system uses the General Radio D.C. amplifier and electrometer type 1230A which has a sensing electrode transparent to the printing beam. The invention may be used with systems in which the toner image remains on the photoconductive surface or is transferred to a receiving sheet, and again, the toner may be chosen to adhere to the charged or discharged image areas. The meter is set to terminate the exposure when the field has changed by a predetermined amount for fringe development by powder cloud liquid development or cascade development with no earthed electrode near the image surface. The exposure is ended at a predetermined fixed value for magnetic brush, liquid or powder cloud development with a grounded electrode by the image surface. The apparatus may be used to produce colour separaters prints from a multi-colour transparency.

Title: Circuit arrangement for processing parts of words in electronic computers
IPC: H03K21/00
Filed: 1963-07-26
Abstract: 1,030,237. Data storage. STANDARD TELEPHONES & CABLES Ltd. July 26, 1963 [July 31, 1962], No. 29716/63. Heading G4C. In a data processing system employing a fixed word length, means are provided for handling variable length words. A register of the fixed word length is associated with means for selecting desired beginning and end positions within the fixed word length. The arrangement is applicable to the storage and read-out of data and in a comparison operation. As described, the fixed word length is ten characters. To select a part of such a word for writing-into or reading-out from a 10-stage register R (Fig. 1, not shown), each stage of which corresponds to a 7-bit character, 5-bit coded representations of the desired beginning and end positions are entered in stores Rl, Rr, the outputs of which are converted to 1-out-of-10 form thereby setting a stage 0-9 of a ring counter Z, which set stage corresponds to the desired initial position, and enabling one of ten gates U7 (only one gate shown) connected to the respective outputs of the counter Z for indicating the desired end position. Outputs A0-A9 from the counter stages are connected to enabling gates such as U10, U11 associated with the corresponding stages of the register R. The counter Z is stepped on from its marked stage, each step causing transfer of a character between a data bus I1 and the marked stage of register R. When the desired end position is reached a corresponding gate U7 is opened, thereby resetting counter Z to an " idle " state L and providing an output signal EU which, inter alia, de-activates the counter Z. By providing additional circuitry corresponding to Fig. 1, part of a word stored in register R may be compared with a part of a word stored in relatively different positions in another register (not shown), the selected part of the second word being supplied on a bus I2 and the comparison being effected in a comparator VGL2, any inequality being signalled via gates U27, O1 to output EU. The counter Z is reversible so that words may be scanned in either direction. The circuit of Fig. 2 (not shown) may also be employed to transfer a block of words to a store (not shown), each word being fed via the register R to a predetermined part of a full-length word location in the store, an end-of-block symbol e being recognized in a circuit SZE to terminate the transfer. To transfer to a store a block of words each of which may exceed the length of the register R, each word is followed by an end-ofword symbol ef also recognized in circuit SZE, so that the words may be arranged as in Fig. 4 (not shown), each word commencing at the beginning of a new storage location. The circuit of Fig. 2 may further be employed to indicate the position in register R of a predetermined character applied as a " search criterion " over bus I2, the register R being scanned until a comparator VGL1 detects an equality, the required position, which corresponds to the marked stage of the counter Z being obtained as an output via gate U9.
