Title: Telephone hand set sterilizers
IPC: A61L2/10
Filed: 1966-12-07
Abstract: 1,129,189. Telephone handset sterilizer; sanitary and hygenic devices. R. A. BUCKLEY. 10 May, 1967 [7 Dec., 1966], No. 54667/66. Headings H4J and H5R. A telephone handset is sterilized with ultra-violet radiation in an apparatus comprising a casing in which there is sufficient space to receive the whole of a telephone handset, the casing wall having an opening through which the handset is insertable, a source of U.V. radiation within the casing and a circuit for supplying power to the U.V. source which is adapted to be battery-operated. A casing 11 (Fig. 2) has integral top and sides and is equipped with removable trays 14, 15 placed at the bottom of the casing one above the other. The tray 14 supports an U.V. lamp 21 in a suitable holder together with appropriate circuitry, the space between trays 14 and 15 being occupied by suitable batteries functioning as a power source. The sides of tray 14 extend upwardly adjacent the casing wall and are curved to form a ledge on which support rods 27 for the handset 28 may rest. The interior of the casing may have a light reflecting finish, e.g. white paint, to improve the intensity of radiation received by the handset. One side of casing 11 is equipped with an opening 36 closable by a flexible rubber or plastics material diaphragm 37 which yields as is indicated in Fig. 1 (not shown) to the insertion of the handset but closes round the cord to prevent escape of U.V. radiation. A switch 38 (Fig. 1) is used to energize the U.V. tube. The circuit containing the U.V. source is basically a transistorized inverter circuit combined with a step-up transformer to convert the low-voltage D.C. supplied by the batteries to the much higher A.C. required by the U.V. source 21. The handset may be perfumed whilst it is sterilized by providing a perfume generating device within the container. Alternative positions in the casing, and types of battery for the power source are suggested in the Specification.

Title: Electrographic recording system
IPC: B41J2/41
Filed: 1971-12-07
Abstract: 1369456 Electrographic recording CLEVITE CORP 7 Dec 1971 56752/71 Heading G4H An electrographic recording system comprises a row of recording electrodes arranged in two unconnected groups 26-28 of interdigitated arrays 31-36 having corresponding electrodes 1-4 in each array of a group connected in series, and two rows of complementary electrodes 55- 61 arranged on either side of respective adjacent arrays, the arrangement being such that a selection of a particular electrode (e.g. 2 in array 33 of group 26) is effected by first setting suitches 89, 72 so as to apply a voltage to all electrodes 2 in group 26, then (by means of switches 40, and 77, 78) applying a pulse of opposite polarity to the four adjacent complementary electrodes 57, 58. The voltages applied to electrodes 2 are not sufficient to form a latent image on a recording medium, nor is the voltage applied to the electrodes 57, 58; however the voltage between electrode 2 of array 33 arid electrodes 57, 58 is sufficient, so that only one latent image is formed. In the embodiment of Fig. 2, the complementary and recording electrodes are arranged in overlapping relationship so that voltage fall-off at the end of, e.g. electrode 57 (which would affect electrodes 1, 2) is compensated by the voltage at the end of adjacent electrode 58 Figs. 3a, 3b, not shown): the electrodes 55-61 are arranged in pairs on either side of the electrodes 1-4 so as to compensate for voltage fall-off at the sides (Figs. 3c, 3d, not shown). In this embodiment the complementary and recording electrodes are arranged on the same side of the recording medium; they may however be arranged on opposite sides (Figs. 4, 4a, not shown). In the electrographic line printer of Fig. 5, three groups 93, 96, 99 contain respective arrays 181, 182, 183 &c. each composed of 105 recording electrodes 201-305 arranged in three 5 x 7 matrices; two rows of complementary electrodes 310-313 &c. are arranged as shown. Latent images of a line of characters are formed on a record medium in groups of three: for the first three characters, switching means 94 energizes those recording electrodes, selected to form the three characters (electrodes in arrays 184, 187 &c. also being energized) and switches 321 and 40 energize the two adjacent complementary electrode pairs 310, 311 as before. In the electrographic recorder of Fig. 6, information to be printed is taken from a C.R.T. (α- numeric) display. The input 123 is fed to a shift register 124, each "unit" of 25 bits being gated into a storage 128 from which it is directed in turn to one of two gated electrode drivers 135, 136 by means of a flip-flop 137. The output 141 or 142 of driver 135 or 136 is applied to respective ones of two groups of recording electrodes 120 flanked by complementary electrodes 143- 147 etc.; at the gating of each unit a timedelayed pulse is fed to a shift register 168 which provides an output on each of leads 175, 176 &c. in turn so as to energize complementary electrodes 143, 144 (then 144, 145 &c.) as before.

The fibre band leaves via outlet 9 which may be as shown in Fig. 2 in which escape of vapour is prevented by air drawn in through outlet 9 by vapour passing from compartment 8 to conduit 26 which is connected to passage 11, Fig. 1. The vapour from compartment 8 may be drawn to condensing chamber 17 by fan or ventilator 21 or a blower in passage 11. The impregnating liquid may be swelling agents or organic solvents containing treatment chemicals.

Abstract: 1,144,109. Rejecting pulsed interference; radio navigation. SPERRY RAND CORP. 18 Dec., 1967 [20 Dec., 1966], No. 57303/67. Headings H4D and H4L. The specification describes interference reduction means whereby the operation of a pulse sampling circuit in a receiver of a desired pulsed signal is inhibited on receipt of an interference pulse signal having an amplitude substantially greater than the amplitude of said desired signal. The interference reduction means comprises means for detecting received pulsed signals to the exclusion of continuous wave signals and for producing a pulsed inhibiting signal when a pulse signal is received in excess of a predetermined threshold value, said value corresponding to an amplitude below the amplitude of said interfering signal and above the amplitude of said desired signal, and means for applying said inhibiting signal to the pulse sampling circuit. A particularly described use of the interference reduction means is in the Loran C navigation receiver described in parent Specification 1,094,870, wherein the interference pulses may be due to transmissions from other Loran chains. All received pulses, including said interfering signal are fed in at FROM 13 and fed to a paraphase amplifier 20 via a potentiometer 19, the setting of which determines the level of said threshold value. Antiphase outputs from the amplifier are detected at 25 and 26 and the resultant signals fed to an integrator 27. The detectors and integrator detect the leading edges of the received radio pulses and extend them by an amount compensating for the inherent delay in the receiver pulse sampling circuits. The output of the integrator is fed, via emitter follower 29 to transistor 30 at such a level, under the control of potentiometer 19, that only the high amplitude interference pulsed signals cause transistor 30 to conduct. The sampling pulses are received at FROM 11 and pass, via transistor 32, to the receiver sampling circuits 14. When transistor 30 conducts however, the output impedance of 32 falls and the sampling pulses are no longer passed.

Filed: 1971-12-13
Abstract: 1358599 Nail driving tools U MONACELLI 13 Dec 1971 [22 Dec 1970] 57745/71 Heading B4C A tool for driving headed nails into a workpiece includes members for supporting the head of a nail being driven during the driving stroke of a nail driving element and means permitting the members to be automatically moved to a non-supporting position towards the end of the driving stroke of the element. In a first embodiment (Figs. 1 and 2) the tool is pneumatically operated and comprises a magazine 3 from which nails 28 are advanced by a spring biased pusher into a driving channel 22 along which the nails are driven by a pusher rod 12 secured to a piston 11. Jaws 20 supported the pusher rod have bent ends 21 which in the initial position of the pusher rod, support the head of a nail supplied to the driving channel. Depression of trigger 6 causes a valve 9 to be raised thus permitting supply of compressed air into cylinder 8 to drive the piston 11, the supported nail and the jaws towards the workpiece. The jaws each travel in a respective channel 23. After a predetermined distance the bases of the channels 23 diverge, so that the jaws under bias of spring 17 can pivot out of supporting engagement with the nail. At the point of release of the nail, the shank of the nail preferably extends into a workpiece (Fig. 8, not shown). In a similar arrangement (Fig. 9) a tooth 35 on each jaw engages a stop 37 which engagement assists in moving the jaw to its non-supporting position. A further embodiment (Fig. 12, not shown) includes inclined stop surfaces (25) which assist in moving the jaws into their non- supporting positions. In the embodiment of Fig. 14, upper ends 69 of the jaws are located in apertures in a hollow rod 62 integral with a piston 83 which is slidable within piston 82. The piston 82 carries a pusher rod 57 the head 56 of which coacts with cam pistons 68 on the jaws when the latter reach the diverging bases of channels 73. In operation compressed air passes via bores 67, 86 into space 84 to maintain the piston 83 in the illustrated position. Raising of valve 59 initiates the driving stroke of the piston 82 and simultaneous movement of the piston 83. When the bore 86 comes into communication with bore 66, the piston 83 is abutting buffer 60, and air in space 84 passes to exhaust via bores 86, and 66 so that movement of piston 82 continues so as to open the jaws and fully drive a nail into a workpiece. Return of the pistons is effected by introducing compressed air into chamber 54 and exhausting air from the cylinder space above the piston 82. Initially air passing via bores 65 and 86 effects upward movement of piston 82, and the head 56 on engaging the end of rod 62 effects upward movement of the piston 83.

Abstract: 1448570 Digital magnetic recording systems INTERNATIONAL BUSINESS MACHINES CORP 14 Dec 1973 [26 Dec 1972 (2)] 57949/73 Heading G4C Data is recorded on magnetic tape in the form of a sequence of parallel-bit bytes. A known de-skewing unit has the ability to de-skew a byte whose most leading and most lagging bits are separated by a preset number N of bit periods. Excessive skew is determined by reference to track bit counters and to a counter which counts the number of complete bytes stored in a de-skewing buffer. After detection of the preamble to a block of bytes, counters associated with respective tracks are incremented such that the relative counts (called the read-in counts) indicate the relative lead or lag between the various bits of a byte. When a complete byte has been de-skewed the stage of the de-skewed registers in which the byte is held is indicated by a so-called read-out counter. If the maximum difference between the read-out count and any one of the read-in counts exceeds N, indicating excessive skew, read-back operation is indicated as being faulty. In addition, if the difference reaches a preset number which is less than N a signal called marginal skew is generated, indicating that a track may be in error. There may be a general marginal skew signal, indicating that at least one track is marginally skewed, or there may be a specific marginal skew signal for each track which is so skewed. The system includes circuitry which generates so-called persistent pointers which indicate any track or tracks that has an excessively long error burst. When a persistent pointer related to a particular track is present in the presence of a general or a specific marginal skew signal the system operation relating to that track is altered. For example, error correction may be initiated or read-out from that track inhibited.
