Title: Improvements in pen nibs
IPC: B43K1/01
Filed: 1938-07-16
Abstract: 517,042. Pen nibs. HUGHES, H, R. July 16, 1938, Nos. 21151/38, 37767/38, and 5433/39. [Class 146 (iii)] A pen-nib 2 is provided on its underside with a reservoir attachment formed by a plate 1 anchored intermediate its ends on the nib so that the forward end bears resiliently against the point of the nib and the feed-bar of a fountain pen can pass between the plate and nib at the rear end. The plate 1 is pivoted to the nib by lugs 3 and apertures 4 and the rear end is arranged to bear on the sides of the nib and hold the front end in contact with the pointed end of the nib; in order to permit flexure of the plate the rear end is weakened, for instance by the provision of a slit 10. The forward end of the plate is bent up at 7 into contact with the nib, and its. intermediate portion 8 is stepped and lies spaced slightly from the end of the feed-bar when this is inserted. The part 9 is corrugated to provide traps for the ink when the pen is upturned. The front end of the plate may be bifurcated, and inturned lugs may project into the ink-feed channel. Specifications 516,392 and 517,041, are referred to.

Title: Improvements in moisture traps in tobacco pipes and cigarette holders
Inventor: CLEMENT DAVID MICHAEL
IPC: A24F1/16
Filed: 1954-07-20
Abstract: 766,707. Tobacco pipes and cigarette holders. BYFORD, Ltd., C. May 18, 1955 [July 20, 1954], No. 21178/54. Class 130 An annular space or spaces 16, 20, 24 concentric to the smoke duct 34 and in communication therewith at two separate points along the duct length. have opposed walls so spaced as to retain liquid by capilliary action. As shown, a metal or other connector 6 screwing into a tobacco pipe stem 2 and socketed to receive a mouthpiece spigot carries tubes 14, 26 and the mouthpiece 8 a tube 22. Liquid enters the spaces via holes 40, 36, air escaping via holes 38 and around the free end of the tube 26. Upon dismantling the connector 6 and mouthpiece 8, all surfaces are exposed for cleaning. The spaces 16, 20, 24 are respectively of 0.015in., 0.017in. and 0.020in. width so that they fill with liquid successively, and are of sufficient capacity to serve for a normal day's smoking. The tube 26 may be of metal. The connector 6 may be replaced by a socketed stem. There may be more than three annular spaces. In Fig. 3 (not shown) the tube 26 is dispensed with, the tube 22 being of the same diameter as the bore 32, but the spaces are still sufficient to hold the liquid discharge from at least, one pipe filling. In Fig. 4 (not shown) a cigarette holder has only one annular space between the holder body wall and a tube projecting forwardly from a mouthpiece spigotted therein. According to the Provisional Specification, instead of an annular space or spaces, spaces are defined by longitudinal or circumferential fins extending inwards or outwards from one or more tubular members concentric with the smoke duct, or by many parallel thin plates parallel or perpendicular to the duct. The Provisional Specification also describes (a) a single annular space formed in a tobacco pipe by a tube projecting rearwardly from the bottom of a stem socket into a chamber inside a mouthpiece spigot, (b) attachment of the only tube or the outer tube to the mouthpiece instead of to the stem and (c) location of the tube or tubes within the stem instead of the mouthpiece.

Title: Improvements connected with automatic weighing machines
Inventor: JONES WILLIAM
IPC: G01G23/36
Filed: 1952-08-23
Abstract: 719,350. Weighing apparatus. AVERY, Ltd., W. & T. Nov. 18. 1953 [Aug. 23, 1952], No. 21213/52. Class 143 In order to totalize a series of weighings, an indicator disc 18, Fig. 2, can be periodically clutched to a spindle 4 which rotates in accordance with a single weighing, and the number of complete revolutions of disc 18 is counted by an electrically operated counter. As shown, a solenoid 10 when actuated draws members 13, 14 inwards to declutch disc 18 from clutch member 6 keyed to shaft 4. When solenoid 10 is energized, members 13, 14 are allowed to separate under action of spring 8 and clutch 18 to 6, so that 18 can be rotated either as the weight is applied to or removed from the member rotating shaft 4. Thus by suitably operating solenoid 10, disc 18 can be stepped on in accordance with individual weighings. At each complete revolution, a contact 19, 20 is made to actuate an electrical counter. To prevent contact 19-20 being made twice when disc 18 oscillates about its position of rest, a solenoid 23, Fig. 3, is energized to rock a spring-loaded catch 24 to co-operate with a stop 25 on disc 18 to prevent the disc swinging back beyond the zero mark, but allow it to progress beyond the zero mark on the next weighing. The solenoid 23 is de-energized when the finger 19 makes contact with a contact diametrally opposite contact 20. Specification 662,455 is referred to.

Title: Improvements in and relating to electronic apparatus for reading symbols
Inventor: BAILEY CHRISTOPHER EDMUND GERV
IPC: G06K9/00
Filed: 1957-07-04
Abstract: 860,568. Automatic character - reading. SOLARTRON ELECTRONIC GROUP Ltd. June 27, 1958 [July 4, 1957], No. 21232/57. Class 106 (1). In an automatic character-reading device there are a number of separate character-scanning devices 10a, 10b, 10c and a central control-station containing storage means, and a recognition matrix, and switching means are provided to select a channel from any one of the scanning devices for storing and decoding signals derived thereby. Sensing.-The scanning devices can be in the form of cathode-ray tubes to which are applied deflection voltages to cause the beam to scan the character in a series of ten parallel lines. In the form of Fig. 3 the character 21 is imaged on the screen of a television camera tube 26 and is scanned by means of the time bases 107, the output on line 15 being amplified and applied to the write gun of a storage tube 103, plates 104 supplied by time bases 107 serving to record the character image on the screen of the tube. The character image is scanned by the reading beam from electrode 105 which caused by time bases 14 applied to plates 106 to make scans over the character image to produce an output from grid 108. The image may be scanned several times to eliminate errors due to imperfect printing or positioning, e.g. as in Specification 850,581. The switches 12 and 16, Fig. 1, are controlled through a device 18 by control signals on leads 19a-19c to connect the desired scanning device to the time bases 14 to cause scanning and to connect the corresponding output line 15a-15c through the clipper 17 in parallel to diode gates 28. Lines 33 are pulsed in sequence in synchronism with the scanning signals and when there is coincidence between pulses on the lines 33 and diodes 28 outputs on lines 29 set flip-flops 30 of which there are a hundred corresponding to ten sampling points on each of ten scans. Each flip-flop has a pair of outputs, one of which has a signal and these are connected in empirical combinations with a series of ten vertical output lines 39. The connection units 40 may be as described in Specification 850,582. A signal produced on the line 39 representing the character sensed passes via a terminal block 41 or a decimal-binary encoder and a switch 43 to a utilization device. The scanning waveforms may be such as to cause the scanning raster to advance from one character to the next in successive scans. Alternatively the character may move relative to the sensing device. In another form the scanners each have a manually-operable switch to connect them with the central station and an interlock prevents any switch being operated if another scanner is already connected. A lamp indicates that another scanner is in operation.

Abstract: 1453368 Automatic voltage control INTERNATIONAL BUSINESS MACHINES CORP 17 May 1974 [21 June.1973] 22241/74 Heading G3R  A power supply circuit, with a plurality of interdependent outputs, includes circuits for comparing each normalized output voltage with a reference voltage to produce respective error signals. Some or all of the error signals are combined to form a control signal which is used to adjust all the output voltages together. As shown in Fig. 2, loads L1, L2 are connected to respective outputs E1, E2 of a power supply 11. The load voltages are measured by voltage dividers 23, 24 and 25, 26 each of which reduces the nominal output voltage to the same value, allowing comparison in operational amplifiers 29, 30 with a single reference voltage Vr. The resultant error signals are summed over resistors 33, 34 which are dimensioned according to the required tolerance on each of the output voltages, so that the control signal produced by an amplifier 36 is a weighted mean of the original error signals. The control signal is fed back to the power supply 11 over a control circuit 21 which may include a voltage controlled oscillator and single shot circuit connected to a switching transistor controlling the operation of a transistor oscillator forming, with an output transformer, the supply 11, Fig. 5 (not shown). In another embodiment, Figs. 3 and 4 (not shown), logic circuits are used to determine the most positive and most negative of all the error signals, and these two signals alone are added to produce a combined error signal which controls the power supply in order to keep all the output voltages within their tolerance levels whenever possible.
