Title: Steering device for ships and the like
IPC: B63H25/38
Filed: 1920-07-07
Abstract: 147,182. Flettner, A. Sept. 3, 1917, [Convention date]. Addition to 147,024. Rudders.-A rudder 1<b> is provided with an auxiliary rudder 2<b> at its rear edge, the two being connected by toothed gearing 8, 9 and connecting-rod 11. The gearing is such that when the main rudder is turned, the auxiliary rudder is turned through a larger angle in the reverse direction. This tends to turn the main rudder back until equilibrium is reached, and vibration is then prevented. In a modification, the gearing is replaced by a crossed rope. In another modification, the auxiliary rudder is operated by ropes in the axis of the main rudder, and the main rudder is not directly operated. In a further modification, movement is transmitted to the auxiliary rudder entirely by toothed gearing. The rudders may be locked together in a predetermined position. The main rudder may be provided with an additional pressure surface rigidly attached to its forward edge by stays.

Filed: 1920-07-07
Abstract: 147,183. Winkler, G. Dec. 17, 1918, [Convention date]. Stoppering; opening vacuous bottles by relieving external pressure.-In a process of exhausting, opening, and closing preserving-jars &c., the vessels are closed watertight and placed within an auxiliary vessel which is filled with water, afterwards forced out intermittently, with the creation of a vacuum. Fig. 1 shows a preserving-vessel o, the cover p of which is retained by a spring yoke q, placed within a vessel a filled with water and closed by a cover b resting on a packing-ring and covered by a water seal. A hole d extends through the cover and its handle c and is closed by the hand during the evacuation of the vessel by operation of a water-pump e. The uncovering of the hole d allows air to enter and by its pressure to seal the cover on the preserving-vessel. The vessel is opened by placing a spring under tension in the niche between the cover and the side of the vessel, which is then placed in the water vessel a, and the latter is evacuated, the spring entering further and lifting the cover.
Patent GB-1300165-A (GB)
Title: Character synchronizer
IPC: H04L7/033
Filed: 1970-04-22
Abstract: 1300165 Data transmission synchonization RCA CORPORATION 22 April 1970 [29 April 1969] 19353/70 Heading H4P In a telegraphic receiver, n-bit binary parity encoded character signals are parity checked and if correct a 1-bit is added in the n-th paritybit position of each character, the recurring 1 in this position in successive characters synchronizes the signals. In the arrangement of Fig. 2 circuit 12 checks the parity of incoming signals and issues a modified bit pattern, which includes the parity check 1-bit, and which is compared bit-by-bit at AND gate 44 with a sequence of n 1s circulating through shift register 14 and around path 15, 17. Only the co-incidence of 1-bits causes a 1-bit to pass through AND gate 44 back into the register. After very few character signals the only 1-bit left in circulation is the 1-bit corresponding to the parity check 1-bit of each character signal. AND gate 42 generates a synchronization signal at output 21 as soon as and each time the remaining 1-bit appears in the n-th register position. Flip-flop 18a is set by the synchronization signal which primes AND gate 46 to circulate the remaining one bit through the register independently of AND gate 44 and therefore the input signal. AND gate 32 checks that the synchronization signal co-incides with the parity check 1-bit of subsequent characters. Lack of co-incidence on three consecutive characters sets counter 30 to operate detector 32 to produce a trigger signal T which resets flip-flop 18a and fills the shift register with 1-bits causing the resynchronization process to start.

Abstract: 856,996. Magnetic recording and reproducing- apparatus. TELEFUNKEN G.m.b.H. June 24, 1957 [June 23, 1956], No. 19744/57. Class 40 (2). A magnetic sound transducing apparatus employing an elongated magnetic recording medium comprises driving-means for maintaining constant the speed of the recording medium past the transducing heads. A magnetic tape 5 is drawn past the transducing heads 12 and 13 by a driven capstan 3 rigidly connected to a flywheel 1. Prior to passing over the transducing heads the tape passes over a roller 4 which is unitary with a flywheel 2. Pressurerollers 6 and 7 are mounted on a #-shaped bar 8 which also carries a roller 9 adapted to engage both flywheels 1 and 2 when the bar is in the position shown in dotted lines. In this position the tape 5 is stationary and the flywheel 2 is driven from the flywheel 1 so that roller 4 rotates at the same speed as the roller 3. When the bar 8 is moved to the position shown in full lines the roller 9 is disengaged from the flywheels, the tape is driven by the roller 3 and in turn drives the roller 4 which maintains a constant drag on the length of tape between the two rollers 3 and 4, due to the friction of the roller and flywheel bearings. An eddy current braking action may also be introduced by mounting a coil carrying direct current in the vicinity of the flywheel 2.

Filed: 1966-05-06
Abstract: 1,198,621. Ultrasonic flow detection. D. O SPROULE. 13 July, 1967 [6 May, 1966], No. 20001/66. Heading H4D. Dispersion in a wave transmission medium is corrected at the receiving end by transmitting the received signal through an "impersive" medium to a further receiver. As applied to ultrasonic flaw detection in a plate 4 (or thinwalled tubing) a short pulse of Lamb waves is generated, the mode of vibration being the first asymmetrical mode, and travels across the plate; higher frequencies travel at higher velocity and the input to receiver 5 is frequency-modulated as shown. If flaws in one particular region are considered a correction system need be provided only for one amount of dispersion (since the amount of dispersion is a function of distance travelled); the correction system utilizes the first symmetrical mode of vibration in a plate 8. For correction of dispersion for signals arriving from any range several receiving transducers 9 are provided and switched into circuit sequentially, Fig. 2 (not shown); a suitable gating pulse generator is based on a nickel delay line, Fig. 3 (not shown). The initial transmitted pulse may be frequency-modulated, Fig. 4 (not shown); pulse compression is achieved as described in Specification 604,429. Coupling the ultrasonic energy into hot material under test is then possible with air as the couplant. The invention is stated to be applicable for radio wave transmission correction.

Filed: 1943-12-01
Abstract: 576,273. Fettling tiles. BOULTON, Ltd., W., and MORRIS, J. Dec. 1., 1943, No. 20024. [Class 87 (ii)] In a tile-fettling machine in which the tiles are slewed round whilst travelling through the machine on a conveyer 6, an upstanding buffer 5 is adjustably mounted close to the slewing device 1 so that it can be set to regulate precisely the amount of slewing movement, jamming on the conveyer due to imperfect re-alignment of any of the tiles being thereby prevented. A tile 10, after having two opposite side edges fettled (by means not shown) is carried forward into contact with a convex. button 1 on an arm 2, the button engaging the underface of the tile near a side edge. The tile is thereby slewed round, the extent of slewing being limited by a rubber &c. buffer 5 which engages an edge of the tile. The buffer projects upwardly from an adjustable arm 7. After passing the slewing device, the tile is thus correctly aligned to enter guides 11 leading to a further set of fettling knives which act upon the other pair of side edges of the tile.
