Title: Method and device for setting clocks right from a distance
IPC: G04C11/04
Filed: 1928-03-08
Abstract: 286,701. Etablissements L. Hatot. March 9, 1927, [Convention date]. Controlling clocks.-A master - clock controls secondary clocks by wireless, the time signal comprising a series of impulses the recurrence of which corresponds to the periodicity of a pendulum at each secondary clock, so that the impulses are given to the pendulum always in the same direction, the amplitude of the pendulum thereby increasing until it closes a switch to set the secondary clock minute hand directly. The duration of each impulse is substantially equal to half the swing of the pendulum. The invention is stated to be applicable also the distant control of switches for public lights, the change-over of tariff meters, and electric sub-stations. The invention mav also be used with radio communication methods along telephonic wires or electric mains of any sort without interfering with the normal work thereof. Fig. 1 shows the apparatus at the secondary clock, 1 being an ordinary wireless receiver, 19 a thermionic valve, and 12 the pendulum carrying a magnet 13 coacting with the coil 14. 5 is the usual heart-shaped cam rigid with the minute hand and with a sleeve mounted frictionally on the minute hand spindle 4. When sufficient of the correctly-timed signals have been received the coil 14 will have gradually increased the amplitude of pendulum 12 until the switch 11 is closed. This energizes a magnet 8 so that a projection 6 on its armature 7 settles in the 'bottom of the notch of cam 5. Thereafter this continues until the signals cease. When the time signal has ceased the projection 6 will no longer enter the cam and the minute hand will resume its rotation from the correct position. In a modification, the switch 11 is closed by a pawl-shaped block on the blade 11, this block being catuated by the teeth of a ratchet wheel which is rotated by a pawl carried on the pendulum when the latter has reached a sufficient amplitude. In another modification, Figs. 6 and 7, the pawl 43 on the pendulum 12 rotates the ratchet wheel 40 once for each complete series of time signal impulses until the pawl rides idly backwards and forwards on a blank portion 40<1>. A cam 41 rigid with the wheel 40 thereby permits a lever 42, Fig. 7, to fall and coact with the cam 5 as before. After the time signal, as the oscillations of the pendulum die down, Hipp mechanism 48, 49 raises a lever 46 and pawl 44 so that the wheel 40 is rotated slightly to leave a tooth ready to engage the pawl 43 at the next time signal. In a modification, this initial work of the pawl 44 is produced by a second pendulum controlled by a special signal.

Title: Improvements in transmission gear for overhead camshafts of internal combustion engines
IPC: F01L1/02
Filed: 1927-03-16
Abstract: 292,241. Inshaw, G. R. March 16, 1927. Cranklinkages; cranks and levers.-An overhead cam shaft 17 for the valve gear of internal - combustion engines is driven from the half-speed shaft 4 by means of a shaft 12, which is connected at its ends to crank pins 7 and 15 on the two shafts 4 and 17, and is mounted in a casing 14 so as to reciprocate axially and to oscillate about its axis. The ends of the shaft 12 are fitted with housings 11, 11<1> carrying members 8, 8<1> which engage the crank pins 7, 15- and are formed with vertical trunnions 9, 9<1> journaled in the housings. The crank pin 15 is formed on a block 16 capable of slight radial, play in a flange 17<1> on the cam shaft, for example as described in Speci. fication 230,555, to allow for expansion of the cylinder block. The housing 11<1> is adjustable axially of the shaft 12. Balancing-weights are provided at 25 and 26, and an additional weight may be mounted on the shaft 12. 'The shaft 4 may be arranged on the same side of the shaft 12 as the shaft 17, so that the shafts 4 and 17 rotate in the same direction, instead of in opposite directions as with the arrangement shown. The trunnion fittings may be replaced by ball joints.

Title: Improvements relating to the scavenging of two-stroke sleeve valve internal combustion engines
IPC: F02B75/02
Filed: 1940-04-23
Abstract: 541,409. Cylinder ports and passages. KAMMER, G. S. April 23, 1940, No. 7331 and 9850. [Class 7 (ii)]  Scavenging of two-stroke sleeve valve engines is assisted by arranging the admission ports at or near the bottom or outer end of the cylinder,and the exhaust ports between the admission ports and the inner end of the cylinder, both sets being distributed all round the circumference. Fig. 1 shows an engine with a sleeve valve 3 arranged in line with a short liner fixed at the inner end of the cylinder, the upper edge of the sleeve controlling exhaust ports 6, while admission ports 4 for air or mixture are controlled by ports 11 in the sleeve and by the piston. The exhaust passages 7 lead to an annular receiver 8 and may diverge outwardly as shown, or may slope downwards and outwards. The inlet passages 4 may be tapered and sloped in the same way as indicated in Fig. 7, or may have an abrupt change in section as shown in Fig. 1, the passages in either case communicating with an annular receiver 9 supplied through a duct 10 from a blower 5. In modifications the sleeve valve may operate between a cylinder liner and an extension of the crank case. Scavenging is effected in the manner indicated by the arrows in Fig. 7, the cylinder head being shaped as there shown, or as shown in Fig. 1, to facilitate the flow. The partitions dividing the exhaust ports around the cylinder may be inclined so that the rebound of the exhaust gases, upon reentering the cylinder, will cause a whirling movement of the air or mixture being admitted. The exhaust may be led away to a turbine. Specification 506,326 is referred to.

Title: Improvements in or relating to transmitting or receiving aerials
IPC: H01Q21/06
Filed: 1943-05-21
Abstract: 580,090. Wave guidqs. CORK, E. C., and MANIFOLD, M. BOWMAN-. May 21, 1943, No. 8078. [Class 40 (v)] Radiating or receiving apparatus comprises a hollow conductor 10 of rectangular or like cross-section with one end 12 closed and the other end 11 open to emit or receive electromagnetic waves. The larger dimension of the rectangle is at least twelve times the smaller dimension, and the latter is less than onesixth of the wavelength. The wave energy is emitted or picked up by a portion 16 of the inner member of a coaxial feeder line 13 projecting into the hollow conductor at a point about a quarter wavelength from the closed end 12. The open end may be situated at the feed point 13, as in Specification 580,115, The conductor 10 may be filled with solid dielectric, thus excluding moisture and reducing the dimensions. A quarter-wave sleeve 17 may be fitted over and electrically connected to the conductor 10 as in Specification 580,114 to prevent currents being set up on the rim and exterior surface of the conductor 10. Four such radiators 20 may be arranged in radial fashion as shown in Fig. 2 around the feed line 21, 22, with their larger faces coplanar and horizontal, giving uniform radiation of vertically-polarized waves in the horizontal plane. The inner member 22 of the feed line may extend into a short length 23 of outer conductor for tuning purposes. In a further arrangement, the four radiators 20 are arranged with their smaller faces coplanar and horizontal, and the inner feed line 22 is fitted with four radial arms, the ends of which are bent to lie across the radiators to emit waves of horizontal polarization uniformly in the horizontal plane (Fig. 3, not shown). The radiators may be flared at their open ends, and may be fed by wave guides instead of coaxial lines.

Title: Method and circuit for transforming a stored quantity of electricity into a number of electric pulses proportional to this quantity
IPC: H03K25/00
Filed: 1954-03-23
Abstract: 751,259. Pulse metering. EBAUCHES SOC. ANON. March 23, 1954 [April 1, 1953], No. 8398/64. Class 37. [Also in Group XL (c)] Apparatus for counting pulses at a random rate comprises a one- or two-stable state arrangement of two valves which is converted to a multivibrator arrangement by the received pulses to transmit pulses at regular intervals equal in number to the received random pulses. In one embodiment (Fig. 1) two valves T1, T2 have their anodes and grids cross-connected to produce a two-stable state with either one or the other valve conducting. The grids are connected through resistors to the anode V2 of a third valve TC, so that when a positive potential appears at V2 it causes the non-conducting valve T1 (or T2) to conduct, producing a negative pulse via C1 (or C2) to cut off the other valve, until the condenser charges sufficiently to release the first valve, and the two valves continue as a multivibrator for the duration of the positive potential on V2. In the application shown, to count random positive pulses received on the grid of a further valve T normally biased to cut-off, each received pulses causes a negative surge to appear on the grid of valve TC and a corresponding positive surge on the anode V2, the circuit components being such that the duration of the positive surge on the anode V2 produces one change in the condition of valves T1, T2. The receipt of further positive pulses by valve T produces further negative surges which are stored by condenser C which discharges at a linear rate, so that the pulses transmitted by valves T1, T2 at the multivibrator frequency is equal to the number of pulses received by valve T at a random rate. In a modification (Fig. 2, not shown) the valves T1, T2 are connected in flip-flop manner, having only one stable condition, and the advent of a positive potential on anode V2 of valve TC causes one change-over for each positive pulse received by valve T.

A printing press comprises a plate cylinder and an impression cylinder arranged to rotate in either direction of rotation, an ink pick-up roller 16 adapted to rotate in one direction of rotation, an inking drum 25 adapted to rotate in a direction determined by the direction of rotation of the printing couple, inking rollers 18 and 20 for transferring ink from the roller 16 to the drum 25, and two pairs of side plates 22 and 24 for journalling the transfer rollers 18 and 20 respectively, the said plates being mounted for limited simultaneous displacement about fixed axes to bodily displace the transfer rollers so that the roller 10 either contacts the roller 20 or the drum 25. In the latter arrangement the roller 20 functions as a distributing roller with respect to the drum. To accommodate a reversal in the direction of rotation of the printing couple, a power cylinder 42 is actuated to displace a cam member 37 causing cam 36 to rock side plates 22 in an anti-clockwise direction about shafts 33. The plates 24 are rocked by connecting links 60 and the roller 18 is moved from the Fig. 2 position into contact with the drum 25, Fig. 3 (not shown). The shaft 50 of the roller 18 is received at each end in a socket having a fixed portion 46 and a portion 47 pivoted thereto at 51. The two sections are pivotally mounted on an eccentric stud at 52 to enable the contact pressure of the roller to be adjusted. On actuation of a member 54 the roller 18 may be moved out of contact with the adjacent rollers or drum. The roller 20 is mounted in a similar manner to the roller 18. The adaption of the inking mechanism may be accomplished by a push-button.
