Title: On-the-fly printer with shortened print cycle
IPC: B41J1/32
Filed: 1974-09-10
Abstract: 1474117 Control of printers SPERRY RAND CORP 10 Sept 1974 [12 Sept 1973] 39415/74 Heading G4H An "on-the-flag" printer incorporates means for shortening the print cycle time. The printer shown schematically in Fig. 1 is conventional apart from the presence of a memory 13. In operation, 8-bit parallel binary signals representing the available characters in their order along or around a moving type carrier are entered in a memory 14. Signals representing data to be printed (printable characters and non-printable characters not on the type carrier) are entered in a memory 12 and the contents of 12 are compared at 16 with the contents of 14 for every coincidence position of characters on the type carrier and the print hammers. Successful comparisons result in signals 17 which decrement a counter 19 preset to the maximum number of printable characters; decoder 20 detects a count of zero in 19 to produce a "print end signal" 15. Memory 13 contains 256 storage locations. When the binary signals are sent to memory 14, a "1" is stored in the corresponding locations in memory 13. The binary signals sent to memory 12 then address their corresponding locations in memory 13; if a "0" is stored at an addressed location (i.e. the signal sent to memory 12 has no counterpart in memory 14 and is thus non- printable), a signal 23a decrements counter 19. Thus, when printing begins, the count in 19 corresponds to the number of printable characters in memory 12, rather than the total number of signals stored therein, so that the "print end" signal is produced without unnecessary delay.

Abstract: 1477828 Plastics material lids for containers; easy-open containers PLASTONA (JOHN WADDINGTON) Ltd 23 July 1974 [21 Aug 1973] 39455/73 Headings B8T B8C and B8D A lid 10, thermoformed from plastics sheet by means of vacuum, fluid under pressure or mechanical forming or a combination of these methods, has a downwardly directed peripheral flange 14 provided with a tear strip 18 which facilitates removal or flexing back of the region defined by the line of weakening 16 (Fig. 1). Notches in the flange 14, either side of the end of the strip 18, and the lead in lobe formation 16A aid the initial fracturing along line 16, which is a groove of reduced thickness. Another embodiment is shown in Fig. 3 where the lid 22 has a raised horse shoe shaped formation 28 and a tab 30. The tab is grasped at the end lying between the arms of the horse shoe shaped formation and acts as a lever, the pointed end 32 causing initial fracture along the line of weakening 26. A further embodiment has a tab attached to the lid with a free end lying at the centre of the lid, the free end having a stud which sits on the base of a recess formed in the centre of the lid. The free end of the tab is pulled to fracture the lid along the line of weakening. The lids shown in Figs. 3 to 6 may be applied to containers by a method involving heating and pressing of the lid flange to crimp it around an outwardly extending peripheral flange on the container as described in Specification 1,477,829. Lids without flanges may be secured to the containers by the use of adhesive or welding or a combination of both techniques.

Abstract: 1,271,390. Fog simulator. BENDIX CORP. 7 Aug., 1969 [14 Aug., 1968], No. 39653/69. Heading B7W. [Also in Divisions G1 and G2] A fog simulation system combines light rays 19 (Fig. 1) from a real world scene with light rays 16 which pass through a servo-driven fog film 11; an attenuator 21, a colour correction filter 14, a diffuser 15 and a collimating lens 17 may all be used as shown. A film transport 32 (Fig. 4) is driven via gearing 31 by a servomotor 30 which receives signals from controlling means 33; the input for the latter is taken from an adding means 37 which adds the signals derived from an altimeter reference 34, an altitude bias 38, and a position transducer 39, the transducer being in a feedback loop and sensing the motion of the fog film by means of a gearing 40. The fog film 11 is programmed to give a desired fog simulation sequence for landing and the altimeter output signal, which is a ramp voltage proportional to the height, controls the rate of movement of the film, e.g. four inches per ten feet of height. The sequence is designed to start at a specific height, e.g. 500 feet, but this value may be varied down to zero by adjusting the altitude bias control 38. A ratio altitude bias 3 may be used to vary the magnitude of the altimeter signal passed on to the adder 37 and so change the visual sequence at a given height.

Title: Device for the automatic adjustment of the air pressure in air containers, especially motor vehicle tyes
IPC: G05D16/20
Filed: 1964-09-29
Abstract: 1,082,155. Tyre inflation plant. R. EICHENAUER. Sept. 29, 1964 [Sept. 30, 1963; July 25, 1964], No. 39670/64. Heading A4T. In a device for automatically adjusting the air pressure to a predetermined value in a container, e.g. a tyre, the closing of switch 8 connects a motor 27 to the electric supply 7 through relay contact 24 and drives a programme switch 26 whereby, when contact 28 closes, a solenoid valve 12 allows air from 11 to pass via 10, 14 and nipple 15 to the tyre. Contact 28 then opens to close valve 12 and, after an interval to smooth out and restore pressure equilibrium in pipes 14, 16, contact 29 closes to open solenoid valve 17 whereby tyre pressure is exerted via 16, 17, 18 and 20 on a relay diaphragm 21. Contact 30 of the programmer is merely for automatic switching of the motor. The programme is repeated until the tyre pressure reaches a set valve when the diaphragm 21 is raised sufficiently to contact the adjustable setting screw 22 and open contact 24 after which contact 30 is opened and the motor stops. In a modification for reducing the pressure in a tyre, pipe 10 is opened to the atmosphere and the contact 24 is arranged to be closed every time valve 17 opens to direct pressure to diaphragm 21, until when the pressure is sufficiently reduced, the contact 24 remains open and the motor stops with valve 12 closed the programme followed being as in first embodiment. In a further embodiment incorporating pole change relays the two systems are combined and provision is made for filling, or emptying without the equilibrium interval, more than one tyre using a solenoid change over valve, and the diaphragm relay is replaced by a pointer monometer with movable contacts and a pressure switch device whereby the device starts on connecting the inflating nipple to the tyre. In a further embodiment, the monometer is provided with a settable pointer with a cam operating two switches connected to a control device whereby small, medium and large tyres are respectively given short, medium and long impulses of filling pressure whereby the total filling time is the same in each case.

Abstract: 1281624 Seat adjustments CRAMER INDUSTRIES Inc 18 Aug 1970 39789/70 Heading A4J [Also in Division E2] A telescopically adjustable seat support comprises a closed cylinder 13 which is filled with hydraulic fluid 24 and rotates in a supporting barrel 10, a movement damping piston 29 in the cylinder, an elongated collet tube 44 sleeved on to the top part of the cylinder 13 and slideable on it, and an outer cylinder 57 secured to the seat and sleeved on to the collet tube, and a releasable clamp gripping the inner cylinder to support the seat. The top end of the supporting barrel 10 is welded to a stop ring 9 in a seating 8 in the base 4 of the seat, and the cylinder 13 is rotatably supported by ball bearings 17 at its bottom, removal of the cylinder from the barrel being prevented by bolt 20. A threaded top-plug 26 guides piston-rod 28 of piston 29 which has axial bores 34 allowing vertical movement of the piston. The piston-rod is secured to a cap 46 on the collet to move with it. A check-valve 37 in one passage, increases the upward damping. The lower end of the collet is slotted at 52 to provide ramped fingers 54 which can grip the outer surface of the cylinder 13 when a ring 56 in a recess 59 in the outer cylinder 57 is forced downwardly on to ramps 55. By this means the collet 44 and outer cylinder 57 are supported on the inner cylinder 13. Upward movement of lever 61 moves cross arm 62 and cap 46 of the collet downwardly and so moves the collet tube downwardly with respect to outer cylinder 57 to free the ring from the ramp and so release the gripping fingers and so allow vertical movement of the seat. This movement is assisted by springs 33 which counterbalance the weight of the seat &c. Downward movement of the lever locks the seat in vertical position. Weight on the seat augments the gripping at ramp 55 by pressing the outer cylinder 57 downwards.

Abstract: 1494659 Time domain equalizers; active filters INTERNATIONAL STANDARD ELECTRIC CORP 30 Sept 1975 [8 Oct 1974] 39944/75 [Headings H4R and H3U] In a time domain equalizer, e.g. for a carrier band of 4-60 MHz, having a delay line with several taps spaced from each other by a time difference # which corresponds to a half-cycle of the upper cut-off frequency of the signal to be corrected, and in which the signals at the taps are adjusted in level by voltage dividers formed by differentiator capacitors and low resistances and vectorially added to, or subtracted from the signal to be corrected, which is coupled out via a capacitor C, the variation in frequency response due to the use of the capacitance resistance voltage dividers is corrected by adding to the signal to be corrected an additional signal which is delayed by a fraction of the time difference #. As described the differential capacitors Dl, D2, &c. feed a summing bus SL and a subtracting bus DL which are connected to the inputs of a differential transformer feeding the amplifier A2. The input impedance of the amplifier A2 is 75 # and this impedance is transformed to the region of 10 to 20 # by transformer SDN which is the correct value to terminate the busses SL and DL which are formed as micro-strip lines using circuit board technology. The low frequency response loss of the dividers is corrected by the additional tappings at #/b and #/a where a and b are integers greater than one. It has been found that a single tapping at #/2 provides satisfactory compensation. Previously correction was applied by a frequency conscious network in the feedback path of the amplifier, (Al) Fig. 1 (not shown) which, however, made the input impedance of the amplifier frequency dependent.

Title: Gas burner assembly
IPC: F23N5/08
Filed: 1977-09-28
Abstract: In the device, a solenoid valve (50) is actuated in the gas feed line by a light-sensitive cell (6) which is exposed to the ambient light. A second, light-sensitive cell (6a), likewise exposed to the ambient light, is connected, in a low-voltage direct-current circuit of the control part (40), to the first light-sensitive cell (6), with the effect of a differential light actuation, such that a change, caused by the change of the ambient light, of the resistance in the second light-sensitive cell (6a) compensates for the analog change of resistance in the first light-sensitive cell (6). Consequently, erroneous connections, such as those resulting, for example, from sudden solar radiation or the connection of additional light sources in the working area, are avoided. The device is particular suitable for manually actuated Bunsen burners. <IMAGE>

Abstract: 998,719. Refrigerating. DUNHOM-BUSH Ltd. Nov. 14, 1961 [Nov. 14, 1960], No. 40696/61. Heading F4H. In a compressor-type refrigeration system, the evaporator is defrosted by passing hot refrigerant from the compressor through a defrosting circuit which includes a heat exchanger in which the compressed refrigerant heats refrigerant returning to the compressor to evaporate any liquid refrigerant, and is reduced in temperature before entering the evaporator. As shown, Fig. 1, the refrigeration system comprises a compressor 2, condenser 4, receiver 6, heat exchanger 10, and evaporator 14. The defrost circuit comprises a hot gas by-pass line 32 leading from the compressor output line 3, through a strainer 34 and a solenoid valve 36, to a header 33 of the heat exchanger 22. A line 38 from the heat exchanger leads to the evaporator, the line passing under a condensate drain line 30 and having a loop or branch 43 under a drip tray 28. The hot refrigerant passes through an internal tube 40 in the evaporator to an outlet regulating valve 42, and a line 44 opening into the main refrigerant suction line 20. The evaporator consists of a number of tube assemblies, Fig. 3, joined in series and mounted in an external fin assembly 54, each tube assembly comprising a fin arrangement 56 in the annular passage between an inner tube 50 and an outer tube 52. The annular passages 58 carry liquid refrigerant during normal operation, and the inner tubes 50 carry warm refrigerant during defrosting. Return refrigerant from the evaporator passes from line 20 into the body of the heat exchanger 22 and leaves through line 24, any liquid refrigerant being trapped to the right of a baffle in the heat exchanger with its top edge above the heat exchanger centre line. This liquid is evaporated during defrosting by the hot refrigerant in the tubes 72 extending between headers 33, 37. A small slot at the base of the baffle allows oil to return to the compressor. To initiate a defrosting operation, a solenoid valve 46 at the evaporator inlet is closed by a time clock. The compressor 2 continues to operate until all liquid refrigerant has been evaporated from the evaporator. A fan 16 for the evaporator is then stopped by a thermal switch (not shown), and the valve 36 is opened. Hot gas pressure in the defrost circuit rises under control of the valve 42 and the compressor restarts. Defrosting of the evaporator then proceeds, with substantial condensation of refrigerant in line 38 and evaporator inner tube 40. The defrosting operation is terminated by the evaporator thermal switch which closes valve 36, opens valve 46, and after an interval restarts evaporator fan 16. U.S.A.
