Title: Improvements in record card controlled printing machines
Filed: 1953-09-07
Abstract: 740,790. Statistical apparatus. MAUL, M. Sept. 7, 1953 [Sept. 9, 1952], No. 24712/53. Class 106 (1). [Also in Group XVI] In a record controlled statistical apparatus in which record cards are fed from two different supply magazines 5, 6, Fig. 3, to their own sensing station and the data sensed is printed on a common sheet S from a common printing mechanism, each card carries a group code and other data, which data on one series of cards, e.g. " Item " cards in the magazine 5, is printed on after the other until there is a change in the group code whereupon the feed of the item cards is stopped and that of the other series of cards, e.g. " Summary " cards, is effected so that printing takes place under control of the summary cards fed from the magazine 6. If a difference in group code occurs between the item cards and the summary cards then the machine is stopped. As described each card comprises three decks of data which are simultaneously sensed by three sets of bushes. Each deck has six positions and a perforation in any row represents 1, 2, 4, 8, 16, 16 increments of movement respectively to a series of type wheels. This mechanism together with details of the clutching arrangements for driving each type wheel is described in Specification 739,910, [Group XVI]. The " Item" cards are fed from the magazine 5 by a sliding picker reciprocated by an arm 126, Fig. 4b, having a rightangular lug 126a overlying an arm 124 oscillated from a rotating crank 116. Arm 126 is urged counter-clockwise by a spring 127 and follows the oscillations of arm 124 unless a clutch magnet Km<SP>1</SP> is energized, whereupon its armature 128 engages the lug 126a and prevents feed of the cards. A similar mechanism 129- 136 and magnet K<SP>1</SP> drives feed rollers 112 by means of pawls 137, 138 which effect feeds corresponding to a position space, or a distance from the last position on one card to the next card respectively. Similar mechanisms feed the summary cards under the control of their own clutch magnets.

Abstract: 169,944. Miller, W. J. April 1, 1920. Blowing; delivering molten metal.-Relates to machines for forming glassware of the type in which the moulds are carried on a rotary table. the aim being to adapt such a machine for use with a continuously flowing stream of molten glass. According to the invention, the table rotates continuously and the moulds are made to lag or the delivery apparatus is moved, so that there is no relative motion between these parts at all at the moment when the charge is dropped into the mould. In the form of apparatus shown in Fig. 1, the mould carriers 24 are arranged to slide in curved slots 27 and are formed with a projection 30 which strikes a spring stop 31 when the mould comes into the charging position. The mould is thus held below the feed-opening until the carrier 24 reaches the end of the slot 27 when the projection 30 is forced past the stop 31 and a spring 28 pulls the carrier 24 back to its original place on the uniformly rotating table C. In the form shown in Fig. 4, the charge falls into a divided cup J mounted on a swinging arm 37 which is engaged in turn by spring catches 48 on the rotary mould table C. The cup J is thus carried round above each mould E in turn and is opened by a fixed cam 47 so as to drop its charge into the mould. On reaching a stop 44, the arm 37 is disengaged from the catch 48 and pulled hack below the feed opening by a spring 46. It is then charged ready to swing forward with the next mould.

Abstract: 827,253. Control of D.C. motors. STANDARD TELEPHONES & CABLES Ltd. Aug. 15, 1957, No. 25759/57. Addition to 759,474. Class 38 (3). [Also in Group XL (c)] In an automatic tuning arrangement for an oscillator controlled by any one of a plurality of crystals, a motor driving a tuning element is started when selecting any crystal, the motor speed is reduced when the oscillator reaches a predetermined voltage and is stopped when a point substantially corresponding to the peak output is first reached and the oscillator energy is then no longer supplied to the controlling system. The circuit shown is similar to that of the parent Specification, but includes an additional relay RD. The output circuit of an oscillator, not shown, controlled by crystals selected by a switch ganged to S1 S2 is tuned by a motor M. The oscillator output is rectified and applied as a negative voltage to terminal T1. After changing the setting of the crystal control switch ganged to S1 S2, the motor M drives the output circuit to its new setting. As resonance is approached the rectified output reduces the anode current of the valve V so that the capacitor C4 charges causing the polarized relay RA to close its left-hand contact energizing relay RD which reduces the speed by connecting a resistor R7 across the armature. When the resonance peak is reached, capacitor C4 begins to discharge thus closing the righthand contact of the polarized relay RA which stops the motor M and releases the clutch CL by energizing relay RB.
