Abstract: 1515707 Supply circuits for furnaces OWENSCORNING FIBERGLAS CORP 3 June 1975 [3 June 1974 24 Feb 1975 21 March 1975] 24004/75 Heading H2H Apparatus for heating molten glass by the Joule effect comprises a furnace 11 for containing glass constituents, at least two groups of electrodes 21-26 within the chamber, the electrodes of one group being coupled across one source of alternating voltage and the electrodes of the other group being coupled across another source of alternating voltage, and switching means 52-54 operable to couple the sources such that the sources are connected in series and in an additive sense between an electrode in one group and an electrode in the other group. As shown, three pairs of electrodes 21-26 are provided in the furnace, each pair of electrodes being connected to an A.C. source in the form of a respective transformer 28, 31, 33 connected to a single-phase source 27. The region of the furnace between each pair of electrodes is heated by the power supplied via a respective controller 29, 32, 34 in the form of a saturable reactor or inverse-parallel connected thyristors. In order to increase the heating effect in the region between pairs of electrodes 21, 22, and 23, 24, for example, the switch 52 is closed to connect the sources 28, 31 in series across the path between electrodes 21, 24. The heating is controlled by a controller 55 in the form of inverse-parallel connected thyristors. Similarly, closure of the switch 53 or 54 increases the heating in the path between electrodes 23, 26 or 22, 25. In a modification, the transformers are connected to a three-phase supply.

Abstract: 721,544. Ovens; electric heating. BRITISH THERMOSTAT CO., Ltd. Sept. 19, 1952 [Oct. 15, 1951]. No. 24031/51. Classes 39 (3) and 126. [Also in Group XIII]. The rate at which heat is transferred from the cooking space of a stove to a thermostat mounted externally of the oven is varied by a manually adjustable device. In one embodiment, Fig. 1, a thermo-sensitive element 2 is supported in an oven flue by a bracket 6 attached to the back wall 7 of the cooking compartment. The bracket 6 is formed with projecting ears 10, 11, the former attached to the wall 7 of the oven, and the other ear 11 engaging an adjustment screw 12. The ear 10 is bent so that the bracket 6,springs away from the oven wall 7 unless urged towards it by the screw 12. In another embodiment, Fig. 2, a thermo-sensitive element 13 is mounted in a fixed position within the flue, and an insulator or reflector 14, pivoted about its longitudinal axis, is interposed between the rear wall of the oven and the element 13. By adjustment of the reflector 7 and of convection currents in the flue on the element 13 can be regulated. The thermo-sensitive elements may be located in the insulation compartment of a cooking stove, and they may be of the phial or rod-and-tube type.

Title: Data communication system
IPC: G06F11/14
Filed: 1977-06-09
Abstract: 1532753 Error checking in data transmission NCR CORP 9 June 1977 [18 June 1976] 24077/77 Heading H4P In an error checking and correcting arrangement data is transmitted in true and complement form simultaneously to a receiver which detects any discrepancy between bits received and retransmits to the transmitter a selected one of the data streams received, the retransmitted stream being inverted if a discrepency is detected whereby the error may be detected at the transmitter. The detection may thus be independent of word length. In the event of an error, retransmission of original data is on a word by word basis similar to the original transmission; up to, say 7 retries may be made before a warning is given. Duplex working is envisaged. Opto-electric couplings may provide electrical isolation between the data processors at transmitting and receiving stations.

Abstract: 1,093,464. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 18, 1966 [June 9, 1965], No. 24426/65. Heading H1K. In a sequential method of mounting semiconductor devices, an elongate member of insulating material provided with transverse conductive regions on one face is longitudinally moved through an apparatus which mounts a semi-conductor device on the member, connects the electrodes of the device to respective ones of the conductive regions, and severs the leading portion of the member to produce a completed assembly. As shown, Fig. 1, a ceramic strip 1 having transverse metallized regions 2 is moved in the direction of the arrow by indexing means (not shown), which may use the metallized regions as registering marks. At a first position a planar transistor 4 is mounted with its collector connected to one of the conductive regions, and at a second position flying leads 5 are attached to other conductive regions. The transistor and its flying leads may then be covered with a mass of insulating material and the end portion of the strip is severed as along dotted line 6, to produce an assembly comprising a mounted transistor. The conductive regions 2 extend down the sides of strip 1 so that the assembly can be mounted on a printed circuit. In a modification, Fig. 2 (not shown), the conductive strips are of varying widths and do not extend completely across the strip. Slots (14) are also provided in the edges of the strip to form indexing means. The strip 1 may also be in the form of a semi-flexible ribbon. The semi-conductor devices may also be diodes or integrated circuits.

Abstract: Methyl naphthyl carbinol is obtained by acting upon a mixture comprising methyl naphthyl carbinol and methyl naphthyl ketone in the liquid state with hydrogen in the presence of a hydrogenation catalyst at a reactive temperature below that at which substantial dehydration of methyl naphthyl carbinol occurs.  A copper chromite catalyst is preferred, the hydrogenation being then effected at a preferred temperature range of 100 DEG  to 125 DEG  C. Other hydrogenating catalysts such as nickel and nickel alloy catalysts may be used.  The mixture comprising methyl naphthyl carbinol and methyl naphthyl ketone may be obtained by oxidizing ethyl naphthalene as disclosed in Specification 626,313 of which the present Specification is a division and the hydrogenation is effected in the same way and described with reference to the same flow-diagram as is shown and described for the hydrogenating step in the said Specification.

A hoist, comprising load sprocket 15 driven by oscillating handle 12, is sealed against dirt and water by seals 51, 58 and 61. The handle 12 drives sprocket 15 through the engagement of pawl 42 with nut 29. Nut 29 is threaded at 28 on shaft 26 and additionally engages ratchet 36 which slides along shaft 26, so that nut and shaft lock together to transmit the drive to sprocket 15. Ratchet 36 co-operates with a holding pawl to prevent back rotation under load. Drive handle 12 (Fig. 3).-This is provided with selector handle 19 which, by rotation, positions pawl 42 such that either the load sprocket 15 is driven in either direction or handle 12 rotates freely without driving. Shaft adjustment (Fig. 6).-Shaft 26 is formed with a square end 70 on which is mounted stopwasher 66, the stop 69 of which co-operates with boss 71 formed on nut 29. Stop 69 functions to limit the rotation of thread 28 to prevent end jamming of ratchet 36.

Class 40(1) Apparatus for measuring the unbalance of a rotor by electrical pick-ups associated with the bearings, feeding into a moving coil ammeter is characterized by a synchronously rotating cam which feeds succesive half-cycles of the signals alternatively into the halves of the centre-tapped meter coil winding so that they produce deflections in the same sense, and the cam also open-circuits the meter winding for a short period in each half-cycle, whereby the effects of all the even harmonics and also the third harmonic are eliminated. As shown, Fig. 1a pick-ups 3 at the bearings feed into the split coil winding of meter 10 yia the contacts of a cam 7 rotating with the test body. Cam section A feeds the signals into one half of the meter coil, section C feeds them into the other half winding, and sections B and D open-circuit the meter coil, the durations A and C being equal, and B and D being equal, with the latter being only half of the former. The angular position of the unbalance is located by rotating the cam contacts to the position of maximum reading on the meter 10. In a modification the pick-ups 3 feed into the whole of the meter coil but the rotating cam short-circuits alternative halves of the coil. Two cam discs displaced by 90 degrees, or one cam with two sets of contacts displaced by 90 degrees, may be used to determine the components of the unbalance mass.
