Abstract: 1341344 Patterns DANSK INDUSTRI SYNDIKAT AS 15 Sept 1972 [27 Sept 1971] 43017/72 Heading B3F [Also in Division B7] A pattern-carrying truck comprises at least one pair of laterally displaceable pattern board carriers 11, 13 which at their top edge have rollers 18 to support a pattern board 19 in a laterally displaceable manner. The carriers are arranged in pairs on supports 7, 9 and 8, 10, each carrier being secured to sleeves 15 for sliding on guide rods 16 on the associated support. Each pattern board 19, which has a semi pattern 20, has a flange 21 with a groove to co-operate with the rollers 18. Also, a roller 22 with a vertical axis may be shifted by a hand wheel 23 from one position in the groove in which it keeps pattern board 19 clear of the carrier plate 17, to the other position in which it presses the upper part of the board against the plate 17. Spherical rollers 24 provided in plate 17 are received in corresponding recesses in the board 19 when the latter is in the transporting position. The board 19 may be heated from plate 17 which may contain electric heating elements. Thus with the use of the truck, pattern boards mounted on a chamber end wall of a mould part producing machine may be easily replaced and carried for storage.

Abstract: 1,244,342. Optical aperture arrangements. RICOH K.K. Sept. 11, 1968 [Sept. 29, 1967], No. 43156/68. Heading G2A. A web 13 having a number of spaced parallel slots and a plate 12 having a single slot are moved perpendicularly to each other by a rack, pinion and sprocket arrangement such that the slot in plate 12 intersects each of the slots in web 13 in turn to define columns of discrete aperture positions as shown in Fig. 4. The aperture arrangement may be used in the photographic system shown in Fig. 1. A lens 1, with the aperture positioned at 3, forms an image A which is split by a multiple lens 2 into a plurality of discrete portions which are recorded on a film 4. Movement of the aperture to a position 3a allows the split image of another object to be recorded over different portions of sheet 4, and so on for other objects and aperture positions. The image of each object may then be individually viewed by using the aperture in a projection system.

Abstract: 1,049,680. Digital computers; division. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 5, 1963 [Nov. 5, 1962], No. 43554/63. Heading G4A. Division is performed by a trial-and-error method. A quotient is guessed and multiplied by the divisor in unit 10 the result being subtracted from the dividend. The quotient is used to address, through circuit 3, a table lookup device which reads out a higher (or equal) and lower quotient for the next try. If there is a carry out of the subtraction unit the higher quotient becomes the next guess, if not the lower quotient is used. The process is continued until the quotients in registers 5 and 6 are one even and one odd. Whichever of these is used is then the required answer and is transferred to register 14. The result of the subtraction is then the remainder and is transferred to the dividend register 1. If the radix is 16 the initial quotient could be 8 and the first pair of quotients selected are 4 and 12. If the radix is 10 the initial quotient could be 4 and the first pair of quotients 2 and 6. The detection of the highest order out-carry can be by means of carry-look-ahead apparatus.

The shock absorber has two passages extending from the annular chamber above the piston to the chamber below the piston, the first passage 11, 14, 15, 18, 19 extending from an opening 13 in the piston-rod 3, through the piston-rod to the chamber below the piston, and containing a valve element 20; and the second passage 27, 28, 26, 15, 18, 19 extending from an opening 29 in the annular chamber below the first passage opening 13, and containing a valve 30 which opens only after the opening 13 in the piston-rod 3 passes into the piston-rod guide 4. On compression (bump) movements, a valve element 9 in the piston opens to allow flow from below to above the piston. On extension (rebound) movements, when the piston is in the central region of the cylinder, liquid flows from above to below the piston through the first passage 11 and past the opened valve element 20. At the limit of extension movement the first passage opening 13 is covered by the piston-rod guide 4 (as shown) and so pressure above the piston builds up, until it opens the second passage valve element 30 and then the main valve element 20.

In an arrangement for accurately measuring each of a number of resistors, such as temperature responsive resistors, in sequence, the resistors are included in circuit units which are arranged in a series chain Each unit includes a conductor e.g. a 1  in series with a parallel combination having in one arm a second conductor a 2  in series with a switch RLA 1  and in the other arm a resistor under test A in series with a third conductor a 3 , where a 3  = a 2  . Constant current is supplied to all the units in series, with all switches initially closed, and a voltage is derived at 5 related to all the conductor resistances corresponding to a 1 , a 2 . Particular switches are then opened in turn by relays, and the voltage change at the detector 5 corresponds to the resistor under test associated with the relay being operated. The resistors may be condition sensors in an industrial plant, the switching and measuring being controlled by a computer. The initial voltage related to the lead resistors may be stored on a capacitor which is switched as relays are operated so that the stored voltage is subtracted from the output voltage of the system, which then corresponds directly to the resistance under test Fig.2 (not shown).
