Title: Continuous variable gears
IPC: F16H29/14
Filed: 1935-01-31
Abstract: 456,428. Variable - speed gearing. KANTOROWICZ, O., 43, Oxford Terrace, Hyde Park, London, and HEPPNER, F., 93, Genfer Strasse, Reinickendorf, Berlin. Jan. 31, 1935, Nos. 3175, 3176, and 3177. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 1, 1935]. Application for addition to 426,136. [Class 80 (ii)] Variable-speed gearing comprises a number of three-element epicyclic gears, having sunwheels 4 secured to a driving sleeve 2, variablyoscillated planet-carriers 6 and loose sun-wheels 15, the latter being intermittently locked, to impart drive to the casing 13, by means of gapped friction teeth 17a on one or more rotating shafts 17, the teeth being so spaced as to engage successively with ribbed friction surfaces on the sun-wheels 15. The shaft 17 is carried in the driven casing 13 and is rotated by engagement of a toothed wheel 18 with a fixed pinion 19. The planet-carriers 6 are oscillated by toothed engagement with segments 7 on rock-shafts 8, crank-pins 9 on the outer ends of which are dragged around eccentrically-adjustable stationary annular grooves, or, as shown, are attached to eccentric straps 10, rotatable on adjustable stationary eccentrics 11. One eccentric 11 at each end oscillates a pair of planet-carriers, the eccentrics being simultaneously adjusted in opposite directions so that the oscillations are 90‹ out of phase. In order to provide the friction pressure between the shaft 17 and planet-wheels 15, the driving sleeve 2 can yield laterally relative to the driving shaft 1, which passes through, and is connected to it by an elastic coupling 3, and the sleeve 2 is supported in the casing 13 on a rock-shaft 16. In a modification, the epicyclic gears are all arranged substantially in the same plane about the driving shaft, the sun-wheels 4 being driven by a single pinion thereon. The planet-pinions have a ball-and-socket mount on their carriers. In order to provide for more uniform and less sinusoidal oscillation of the planet carriers 6, the teeth of their driving segments 7 are not cut along circular arcs. To provide a free-wheeling action, there should be only one shaft 17 or the friction surfaces of the sun-wheels 15 may be prevented by a stop from engaging the teeth on the shafts 17. The angle of the conical friction surfaces is such that they are selflocking. Specification 426,136 is referred to.

Title: Improvements in Electrical Relays
Inventor: HUMPAGE WILLIAM DEREK
IPC: H02H3/38
Filed: 1967-01-20
Abstract: 1,170,684. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. 17 Jan., 1968 [20 Jan., 1967], No. 3189/67. Heading H2K. A relay, e.g. a distance relay, comprises a comparator for comparing the phase relationship between two A.C. signals S 1 , S 2  and including a coincidence detector for developing pulses each having a duration determined by the period for which the polarities of the signals are simultaneously in a predetermined relationship and a circuit arrangement including at least one core magnetized by the pulses and successively reset a predetermined amount, the core being saturated when the pulses are of sufficient duration and causing the circuit arrangement to provide an output. In the relay shown, the signals S 1 , S 2  are amplitude limited by diodes 5, 6 and applied as substantially rectangular waveform signals to input windings 9 on " square-loop " cores 7, 8, each having two output windings 10, 11 wound in opposite senses. The outputs from this coincidence detector are applied to a pulse-width detector constituted by two single windings on " squareloop " cores 12, 13. The cores are successively " set " and " reset " by the positive- and negative-going pulses and when the pulse length is sufficient the cores saturate so that the whole of the signal voltage is dropped across load resistors 14, 15 for the periods in which the pulses exceed the predetermined length. The resulting short pulses are applied through diodes 16, 17 to an integrator 19 formed by a single winding on a square-loop core, an output being produced across a resistor 20 when the core saturates. In a modification, Fig. 6 (not shown), the pulse-width detector serves as the integrator, the cores having input windings connected through diodes to the windings 10, 11 and being provided with reset windings energized from a D.C. source. One of the windings 11 may be oppositely wound so that while the output from the windings 10 represents the sum of the signals, that from the windings 11 represents the difference. In this case, the sum may provide the signals for setting the cores and the difference may provide the signal resetting the cores, Figs. 8, 10, 11 and 13 (not shown). These Figures also illustrate various forms of pulse width detectors and integrators. The coincidence detector may be formed by a rectifier bridge circuit Fig. 14 (not shown) or by a resistor-diode network, Fig. 16 (not shown).

Abstract: 562,111. Mixing air and gas. GRAVEN, G. F., and GARNEET, G. W. G. March 2, 1943, No. 3402. [Class 7 (ii)] An automatic air inlet valve G for a mixer for-air and producer gas &c. in open communication with the engine is actuated by suction which draws down a piston K, connected by a link J and arm H to the valve, against the action of a spring M, the suction depending on engine speed and the position of a gas valve B. When' used with an engine designed for compression ignition, a stop 11, Fig. 3, limiting the maximum fuel delivery is set to provide only the small quantity necessary to ignite the gas and after the control has contacted this stop, a lost motion connection P permits the continued movement of the accelerator to control the gasvalve B. When the mixer is not in use, a pin- and-slot connection O on the gas valve control rod C renders the valve inoperative.

Title: Laminated paper products
IPC: B31F1/28
Filed: 1977-01-27
Abstract: The method for producing corrugated sheets consists in subjecting the flat sheet of paper used as starting material to a heavy corrugation which leads to the formation of peaks and troughs having a total height and corresponding depth (H) which is greater than at least one fifth of the pitch of the corrugation (Pt). In order to obtain a sheet of considerable total thickness (H), the corrugation is carried out between corrugating rollers (C1, C2) having profiles which are partially conjugate in their cross sections and cavities which are elongated along their perimeter. During corrugation, the peaks of one roller penetrate into the troughs of another roller. The cushioning pad obtained is satisfactorily elastic to compressive forces and resistant to bending forces. It is used to pack and fill boxes containing relatively fragile products such as chocolates and other confectionery. <IMAGE>

Abstract: 252,229. Horn, F. E. J., and Sch÷ppe, O. [Firm of]. Feb. 12,1925. Fire-alarm systems and apparatus; signalling over power circuits.-Relates to fire-alarm systems in which the ordinary lighting or power circuits are used for operating the alarm. As shown, contact VIII, IX operated automatically in case of fire or manually operated contacts, such as VII, are connected across the bus-bars B which supply electric lamps &c. C. The busbars are supplied from the main bus bars A, through eleotromagnetically - operated switches I - IV, which are located at a central point and aro operated only by currents of a value greater than the normal lighting or power current. Each switch is normally held closed by a catch e but when, due to the closure of an alarm contact, a short-circuit current flows, the catch is withdrawn to allow the contact arm a to open the lighting &c. circuit and bridge contacts i, k in the circuit of an alarm bell VI. The switches on the sections supplying the pairs of bus-bars B may be graded equally so that the switches I, II, or III, IV may operate simultaneously or each switch may be differently graded so that when an alarm contact is closed one switch only is operated. In the latter case, the second switch provides an additional break in the circuit upon the passage of abnormal short-circuiting current. A resistance n may be connected in series with the alarm contact in order to reduce the value of the short circuit current.
