Title: Receiver for video signals
Inventor: VERHOEVEN L A J
IPC: H04N7/32
Filed: 1973-01-31
Abstract: 1412161 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Jan 1973 [3 Feb 1972] 4734/73 Heading H4F When a differential pulse code modulation video signal is decoded by use of an integrator with a long time constant (much greater than a line), a small propagation distortion of the video signal level will accumulate through the integrator and produce an erroneous level displayed video signal of at least one line in length. To overcome this the level of the blanking signal is monitored for each line and detection of an incorrect level causes the display of an unaffected line, The D.P.C.M. video signal from pulse regenerator 6, comprises groups of four pulses, three giving the magnitude of the differential change and the fourth giving the sign of the change. These are converted to a parallel format by converter 11 and fed to up/down adding circuit 10. The "actual" video seven bit code signal is converted to an analogue signal by weighted resistor array 17/23 and summer 76. The video signal for each line is fed to input 30 of switch 29 via a "main channel" delay 28 and to input 31 via "correction channel" delays 28 and 34. Here the desired blanking signal level is represented by the code 1111111, and is detected by a seven input AND gate 35. Thus at the commencement of each line, if the blanking signal has the desired level, the 1 signal from gate 35 sets bi-stable 37 to give a signal at its Q output, and if the desired level is not detected the resulting 0 signal from gate 35 causes bi-stable 37 to give a signal at its Q output. Modifications of the "main" and "correction" channels are given (Figs. 2, 3, not shown). The delay from the output of the circuit 10 to the switch input 30 should be one line period greater than the delay from said output to the Q and Q outputs of the bi-stable.

Title: Improvements in or relating to signalling arrangements for motor vehicles
IPC: B60Q1/38
Filed: 1923-02-19
Abstract: 195,359. Benjamin Electric, Ltd., (Assignees of Benjamin, R. B.). March 27, 1922, [Convention date]. Road - traffic signals on vehicles.-In a direction indicator for motor vehicles of the type comprising right and left hand signals, manually operated means for initiating the operation of either of the signals, and electromagnetic means controlled by the steering mechanism for continuing the operation of the signal, the manual means comprise a pivoted switch which is held in either of its two signalling positions by an electromagnet until released by movement of the steering mechanism. As shown in Fig. 2, the steering mechanism operates a switch which comprises an arm 28 co-operating with contacts 29, 30, 31. When the arm is in the usual position, i.e. on the contact 31, the manually operated switch is connected in circuit with the battery 32, but when the arm is moved to the right or left the manually-operated switch is cut out. The manually-operated switch comprises a lever 17 which is manually retained in the neutral position by a spring 18, but is capable of being moved to the right or left to make contact with either of the contacts 19, 20 to light one or other of the lamps 12, 13. In both of its operative positions, current passes through a coil 22 to magnetize the poles 24 - - 27 which retain the lever in engagement with one or other of the contacts 19, 20. When the driver wishes to make a turn. he operates the lever 17 to light the required lamp, and on making the turn the arm 28 is moved by the steering gear on to one or other of the contacts 29, 30 to complete an alternative circuit for the same lamp and to cut out the manually-operated switch. This latter action allows the lever 17 to return to the neutral position. A modified type of manually-operated switch comprises an arm 76, Fig. 9, pivotally mounted on one pole 81 of an electromagnet 80 and provided with two arms 77, 78 which cooperate with the other pole 79 to hold the arm 76 in one or other of its operative positions. The arm 76 is normallv held in the neutral position by a spring 83 and is adapted to cooperate with two pairs of contacts, one of which 86, 87 controls the lamp circuits and the other 88, 89 the circuit of the electromagnet. The signal lamps 12, 13 are mounted on the vehicle by universal joints, and each is adapted to display a direction indication to the rear and to illuminate the roadway in front.

Title: Improvements in and relating to methods of manufacturing turbine wheels, nozzle diaphragms and other metal structures
IPC: B23P15/00
Filed: 1925-02-24
Abstract: 230,065. British Thomson-Houston Co., Ltd., (Assignees of Steenstrup, C.). Feb. 25, 1924, [Convention date]. Turbines. - A number of buckets or nozzle partitions of turbine wheels and diaphragms are united to a carrying member or between two carrying members, by assembling and holding the elements in relation to one another, then flowing round them a substance which hardens to maintain them in such relation, then initially securing them to the carrying member or members, then removing the hard substance and finally uniting the parts together by fusion of metal. A series of buckets 5 which are cut from a drawn strip are placed in notches 22 in a pair of holding rings 6, 7 respectively integral with or bolted to a base plate 8 and a top plate 9. The plate 9 fits over a post 11 secured by a stud 12 and dowel 13 to the base plate and is adjustable vertically thereon by a pivot screw 16 engaging a recess in the end of the post and carried by a yoke 15 secured to the plate 9. The plate 9 is also provided with a slot 21 which is wider than a lug 20 on the post so that the plate may be circumferentially adjusted by the screws 19 to align the notches on the respective rings. Before placing the plate 9 on the post 11 a ring 27 with a bevelled outer surface is placed against the shoulder 26 of a groove 25 in the base plate so as to form a stop for the inner ends of the buckets, which project at both ends beyond the rings 6, 7. A ring 29 with a bevelled inner surface is then placed against the shoulder 28 in the groove 25 in the base plate and a substance which will harden on cooling is then run in at 30 in liquid form and flows between the buckets and into the grooves 23, 24 in the rings 6, 7, which are respectively undercut and tapered outwards. A suitable substance consists of a fusible metal melting at about 90‹ C. so that it can be remelted by immersing in water below boiling point. Alloys of bismuth, lead and tin or bismuth, lead, tin and cadmium may be used. The plate 9 together with the ring 7, post 11 and the rings 27, 29 are removed after the metal solidifies and the base plate &c. placed in a lathe and the bucket ends machined to bring them to the desired internal and external diameter. A disc 31 which forms the web of the turbine wheel is then inserted and rests on spacing blocks on the base plate. The bucket cover ring 34 is then heated and shrunk over the buckets and the whole is than immersed in water to melt out the fusible metal. The parts are thus separated from the base plate and ring 6 and then welded, brazed or soldered together, preferably by copper in an atmosphere by hydrogen. The structure may then be finished to desired dimensions and the cover ring turned down to desired thickness. Specification 2,26,559, [Class 83 (iv), Metals, Working], is referred to.

Filed: 1942-04-17
Abstract: 556,811. Moulding rubber belts, rings &c. ; cutting machines. HOOVER, Ltd. April 17, 1942, No. 5118. Convention date, June 6, 1941. [Class 87 (ii)] [Also in Groups VIII and XXIV] A block of rubber 58, Fig. 5, from which a number of driving belts or rings are to be formed, is placed on the bottom of a two-part, laterally-expansible mould 16, 16 positioned within a steam-heated block 6. The block is then raised, by means of a hydraulicallyoperated platen 1, Fig. 1, until the mould cavity telescopes over a stationary plunger 26. The mould parts and the plunger have complementary corrugations, the the plunger forces the rubber into the corrugations, the excess rubber spilling over into anchoring recesses 21 disposed around the periphery of the mould cavity. The position is then as shown in Fig. 1, the rubber being in the form of a cluster of circular belts anchored to the mould by studs 21a, Fig. 9. The rubber is then vulcanized. The platen 1 is next lowered, and as it descends fluid under pressure raises a piston 49 and, via plungers 48, 52, maintains the mould in the uppermost position shown in Fig. 1. Rollers 36 which are mounted in the descending steam block 6 run in inclined grooves 34 in the mould halves, so that as the block descends the mould halves are forced apart until they are clear of the rubber cluster. Stops 39 limit the outward movement of the mould halves. The mould then descends with the block 6, the cluster being thus turned inside out and stripped from the plunger (Fig. 9). To facilitate the reversal of the cluster, lubricant is blown by air on to the outer surface thereof. The cluster is then separated from the anchoring recesses 21, the studs 21a are cut away and the cluster is mounted upon the expanding jaws 70 of a mandrel 68 and cut into individual belts by rotating the mandrel against the blades 69 of a gang cutter. The belts thus produced have the flash on the side, not on the pulley-contacting surfaces. A large number of moulds may be operated by each moulding press.
