Abstract: 1436178 Hoppers/conveyers ZAPATTA INDUSTRIES Inc 16 July 1973 [29 Dec 1972] 33729/73 Headings B8S and B8A The supply of disc-like objects, e.g. crown corks, to a reservoir B from which the crowns are removed at a constant rate by a conveyer E, is controlled, in response to a sensor D which detects the crowns in the reservoir, so as to maintain a predetermined level of crowns in the reservoir. Crowns are fed along a supply shoot A to a vibrating trough 12 which feeds the crowns to a rotary bowl 18, vibration of the trough 12 being controlled by the sensor D. The crowns are discharged from the bowl 18 into a passageway 58 which incoroporates a device F for orienting the crowns such that they enter the reservoir all facing the same way. The device F comprises a tongue 62 which engages the skirts of the crowns to direct them into one of two passages 64, 66 according to the orientation of the crown. The passages 64, 66 are twisted so as to supply the crowns with their inner surfaces facing outwardly (as seen in Fig. 1). The reservoir comprises two plates 80, 82 separated by a distance just greater than the height of a crown. The sensor D comprises a photo-cell 92 and a light source 90.

Title: Improvements in or relating to phase detectors for synchronising a local oscillator
IPC: H04N5/12
Filed: 1959-10-07
Abstract: 931,252. Phase discriminators. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 7, 1959 [Oct. 10, 1958], No. 34005/59. Class 40 (5). In a phase discriminator in which rectangular pulses 1 are additively and subtractively combined with a saw-tooth wave 10 as pedestal and the resultant peaks rectified and differentially combined across an output capacitor 11 the saw-tooth slope gives the pulse peaks a corresponding slope so that the rectifiers conduct at different instants resulting in errors. This may be avoided by producing across the capacitor 16 of a R.C. time constant network 16, 17 a saw-tooth voltage 18 compensating the saw-tooth slope and producing flat top sum and difference voltages 14<SP>1</SP>, 15<SP>1</SP> as shown, the top 22 being selected to equalize the resultant maximum and minimum amplitude. Alternatively, Fig. 7, a saw-tooth wave 26 may be added to only one pulse 27 to more than compensate the slope of saw-tooth 10 and make the peaks of resultant voltages 28, 29 slope opposite ways. Alternatively, Fig. 9, an R.C. leakage circuit 16, 17 may be connected across one half of the pulse input so that the pulse peaks of waveforms 28<SP>1</SP>, 29<SP>1</SP> slope opposite ways and their leading edges render the rectifiers 3, 6 conductive at the same instant.

Title: Process for sulphoxidising saturated non-aromatic hydrocarbons
IPC: C07C303/14
Filed: 1966-07-29
Abstract: Process for the preparation of a sulphoxidation product, which comprises reacting a saturated non-aromatic hydrocarbon of 8 to 30 carbon atoms or a mixture of such hydrocarbons with sulphur dioxide and oxygen in the presence of a saturated non-aromatic carboxylic acid ester which is added after catalytic initiation of the reaction. The carboxylic acid ester is preferably derived from aliphatic carboxylic acids of less than 19 carbon atoms and aliphatic alcohols of less than 19 carbon atoms, and is used in amounts between 1 and 5% based on the weight of the hydrocarbon. The molar proportions of sulphur dioxide to oxygen should preferably be about 2: 1, and the reaction is preferably carried out between room temperature and 45 DEG  C.  Alternatively, a mixture of sulphur dioxide and air can be utilized.

The cross-section of the slots 8 is shown in Fig. 3. The launder, and the slots 15, may taper going downstream, so that the plate 7 has to be sprung into position, but can be replaced when worn. A splitter assembly comprises a plate 17 extending between walls 13 depending from roof 19, a lip 20 being located in a desired pair of slots 21 in the launder walls, so that the take-off through the slots 8 can be split at a desired station into concentrate 22 and middlings 23. Tailings 24 are kept separate by plate 25. Alternatively, the splitter assembly may be a hopper with two outlets separated by a splitter plate, the hopper being movable along the launder, or the splitter plate being pivotable so that its upper edge can be located between two chosen slots, by adjustment of a lockable handle.

Title: Improvements relating to remote control systems
Inventor: HURST STANLEY LEONARD
IPC: H04Q9/04
Filed: 1958-10-29
Abstract: 925,704. Selective signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Oct. 29, 1959 [Oct. 29, 1958], No. 34685/58. Drawings to Specification. Class 40 (1). The invention resides in modifications in the control of registry stages in the remote control and indicating system described in Specification 886,663 referred to in the Provisional Specification. Each registry stage, e.g. stage n, is made responsive to the receiver output when the associated stage (N) of the counting chain is activated by the stepping pulses, the registry stage being again made unresponsive to the receiver output when the next stage (N+1) of the counting chain is activated by the next following stepping pulse. This action is achieved by connecting two variable impedance shunt paths from the receiver output to earth, the impedance of the paths being controlled by connections to appropriate transistors in the counting chain states (N, N+1). The shunt paths include either diodes or transistors, Figs. 1, 4 (not shown), which are controlled by counting-chain stages to provide a high impedance path to earth for the receiver output only during the appropriate interval of a stepping pulse cycle.

Abstract: 173,754. Cesbron, L. J. Jan. 10, 1921, [Convention date]. Roller mills.-A process for converting groats and semolina into flour consists in causing the materials to undergo the action of two non-contacting rollers which revolve at high speeds, for example up to and over one thousand revolutions per minute, the rollers revolving at different speeds and being preferably made of a grinding- material such as alundum, carborundum, or corundum. The speed ratio of the rollers may be three to four. Instead of being made of grinding-material, the rollers may be cast iron &c. As shown diagrammatically, the materials fall into a hopper a which distributes them between the rollers b, c. The rollers may be driven independently or motion may be transmitted from one to the other. The apparatus may also be used for extracting flour particles from bran or for cereal crushing.
