Title: Improvements relating to internal combustion engines
IPC: F01L1/12
Filed: 1921-02-24
Abstract: 159,477. Bannister, B. Feb. 25, 1920, [Convention date]. Valves; valve-gear.-The capacity of the cylinder clearance is increased immediately after the explosion by placing a chamber 1 in communication with the combustion space 2. According to the construction shown in Fig. 1, an electromagnetically actuated valve 3 is located between the chamber 1 and the cylinder. The electromagnet comprises a winding 6 which is excited when the explosion pressure acting upon a diaphragm 12 makes contact between the terminals 10, 13. Closing of the valve is preferably effected by a spring-actuated plunger with which the stem of the valve engages towards the end of its opening movement. A modified construction is described in which the valve is opened by the explosion pressure the valve being held in its open position by frictional contact with a spindle connected to a diaphragm acted upon by the pressure in the chamber which communicates with the combustion space. A further modification is described in which the valve is actuated by cam gear. The chamber 1 may be lined with non-conducting material, and one chamber may serve more than one cylinder.

Title: Improvements relating to folding tables and like articles of furniture
Filed: 1943-04-20
Abstract: 565,077. Folding tables &c. FRASER, H. A., and CRIGHTON, P. F. April 20, 1943, No. 6339. [Class 52 (iii)] A hinged table &c. leg is held upright by interlocking parts, one on the leg and the other on the table, the interlock being secured beyond a relative deadcentre position so that any movement of the leg in the direction of folding up moves the interlock still further from the dead-centre position by toggle action. The leg 4 hinged at 6 is locked in standing position by the cranked limb 7 of an L-shaped metal rod 9 fitting into the corner of an angle piece 8, 13, fixed on the leg, the rod 9 serving as a handle for moving the crank to and fro so that full engagement is a little past the dead-centre. A pivoted catch 14 intercepts accidental displacement of the handle 9, the catch dropping by gravity to hold in the handle and raised by hand to allow release. A screw stud 15 supports 9 against falling down when the leg is in folded position. If the handle 9 swings clear of a screw 15 as the leg is being raised, the crank 7 may foul the flange 8 so that it is necessary to swing 9 back by hand first, but to prevent this a cam surface 16, Fig. 8, may be provided on the part 8.

Title: Attitude control system for an aircraft
IPC: B64C27/32
Filed: 1972-02-10
Abstract: 1336974 Attitude control system UNITED AIRCRAFT CORP 10 Feb 1972 [20 May 1971 (2)] 6379/72 Heading B7G An attitude control system for an aircraft has a member for controlling a surface of the aircraft to effect attitude control, for example the cyclic pitch control stick of a helicopter, and comprises means responsive to the rate of attitude change for producing a first signal, means responsive to the rate and amount of movement of the control member for producing second and third signals and means 36 summing the said signals to produce a control signal generating a force opposing movement of said control member. A gain dependent on aircraft velocity is applied to each signal before summing so that the force on the control member is proportional to the load induced on the aircraft by movement of the control member. The system is duplicated, so that the output from summing amplifiers 36 and 36<SP>1</SP> is fed via amplifiers 60 and 60<SP>1</SP> to pressure valves 62 and 621 which generate a differential pressure in fluid servomotors 66 and 66<SP>1</SP> to produce a force on rods 64 and 64<SP>1</SP> which are attached to yoke 16 pivoted at the end of control rod 18 connected to the control member. If the output of the amplifiers 36 and 36<SP>1</SP>, or of the amplifiers 60 and 60<SP>1</SP>, differs by more than a certain amount, then level detector 124 or 130 passes a signal to OR gate 90 which causes solenoid valves 74 and 76 in the servomotor 66 to rotate so that the pressures across the piston are equalized, motion of the rod 64 being damped by restricted orifice 80. Likewise different forces applied by the servomotors 66 and 661 will, if sufficient to overcome spring- loaded detent 100, cause rotation of the yoke 16 about its pivot, causing synchros 82 and 82<SP>1</SP> to signal the OR gate so that the servomotors are deactivated. The said third signal indicative of control member movement is the output of a difference amplifier (46), Fig. 2 (not shown), receiving inputs indicating stick position and trim control. The latter is produced by a potentiometer 150, Fig. 9, and is adjusted by thumbwheels 140 and 142, (for example, one on each stick of dual controls), which comprise insulated conductive sectors (166) alternately contacting concentric slip rings, Figs. 4-8 (not shown), connected to respective orthogonal windings of stepping motors 144 or 152, so that an increment of movement of a thumbwheel corresponding to one sector causes a 90 degree rotation of the respective motor. The motors respectively drive, through gearing, the wiper and the case of the potentiometer 150, so that the voltage output can be adjusted by either thumbwheel independently of the position of the other.

Abstract: 953,840. Reworking baling bands; stretching. E. TIMMERBEIL, and H. TIMMERBEIL. Feb. 18, 1963 [Feb. 21, 1962], No. 6449/63. Headings B3E and B3V. [Also in Division B6] A method of producing baling bands from already used lengths or pieces of band iron is characterized in that the baling bands cut off packages and the like are first subjected to a straightening process and subsequently the straightened band or strip iron pieces are interconnected at their ends and, if desired, cut to length and the free ends provided with cooperating couplings. Used bands are introduced through guide channels 47, between polygonal rollers 11, then through guides 48 to polygonal rollers 12 of larger diameter than the rollers 11 but driven at the same speed from a common motor and sliding clutch. The bands, stretched and thus straightened between the rollers, drop on to a trough 14 from which they are tilted out on to a table 17. They are then fed by hand to a press 16 to be joined end to end by a part 55 of a tool 15 which forms a pair of longitudinal incisions and presses the strip therebetween out of the plane of the strip alternately to opposite sides thereof. Other strips are similarly joined end to end. The unjoined ends of a completed strip are formed with couplings made by a part 56 of the tool 15 which forms pairs of longitudinal incisions and presses out the metal therebetween in a similar manner to that of the tool 55. These ends, when brought together, hook together to form a joint.

Title: Cathode ray tube system
IPC: H01J29/52
Filed: 1960-02-26
Abstract: 948,486. Cathode-ray tube circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1960 [Feb. 27, 1959], No. 6840/60. Heading H4T. The intensity of the trace on a cathode-ray oscilloscope is controlled by a voltage proportional to the instantaneous velocity of the electron beam spot on the tube face and adjustable in accordance with the sweep repetition frequency to compensate for variations caused by changes in the horizontal and/or vertical velocity of the beam and/or changes in the sweep repetition frequency. The control voltage is produced by combining, at point 19 (Fig. 1), a waveform 22 derived by differentiating (circuit 20) the horizontal sweep waveform 11 with a waveform 27 derived by differentiating (circuit 24) the waveform 16 to be displayed (i.e. the vertical deflection waveform) and rectifying the differentiated signal (circuit 26) the combined signal (waveform 28) at point 19 then being modified in ring modulator 34 by a signal derived from the horizontal sweep control generator 9 (switches 30 and 31 in the positions shown) via low-pass filter 32 and rectifier 33 and the output of modulator 34 supplied to the control grid 7 of the tube via a non-linear circuit 29 which compensates for the non-liner voltage/ brightness characteristic of grid 7. The signal derived via filter 32 and rectifier 33 comprises a current which is inversely proportional to the repetition frequency of generator 9 and this compensates for trace intensity variations which would occur if the frequency of generator 9 varied, e.g. if the latter comprised a sine wave source which varied in frequency to enable observation to be made of distortion in amplifiers as a function of frequency. In an alternative way of producing a control signal for the latter purpose (switches 30 and 31 on contacts 35 and 36, respectively), a mono-stable multivibrator 38 produces pulses 40 of width equal to the horizontal sweep period and which therefore have a time spacing inversely proportional to the sweep frequency. These pulses are clamped in 41 which shifts the zero level such that pulses having a positively going portion 43 of width inversely proportional to the horizontal sweep frequency are produced which, after integration in circuit 44, are utilized to control the modulator 34. In a second embodiment (Fig. 2, not shown) employing an electromagnetically deflected tube and having a push-pull vertical deflection circuit the control of the compensating signal for variation in horizontal scanning frequency is effected manually by a potentiometer between the point 19 and the non-linear circuit 29.
