Title: Improvements in, or relating to, hoists, cranes, lifts and the like lifting apparatus
IPC: B66B7/10
Filed: 1941-11-03
Abstract: 551,193. Load-limiting devices. ASEA ELECTRIC, Ltd., and BAYNES, S. Nov. 3, 1941, No. 14138. [Classes 78 (iv) and 78 (v)] In hoists, cranes, lifts &c., in which the load is supported by two duplicate hoisting ropes 16, 17 anchored to a swinging equalising link 1, means is provided for cutting off the power motor in case of excessive load. The ropes 16, 17, which may be in one piece, are fixed each to a grooved wheel 5 journalled on the link 1 and carrying each an arm 12 the lower ends of which are connected by a tensioning device. Against each of the wheels 5 there may be arranged friction discs which can be adjustably pressed against the wheels to take the initial twist of a temporary load due to inertia. The tensioning device may comprise a spring 33 simply pulled against an abutment 34 by a. connecting rod 24, or, in the more elaborate form shown, may include a fluid friction control. In this form a cylinder 22 is attached to the arm link 21 and adjustably screws into the cap 34 through a packing gland 36 in which the rod 24 slides. To the rod 24 is fixed a piston 28 squeezing the spring 33 on to the cap 34. In the piston are two bleed valves 29 opening one on each side and the head of the rod 24 is bored at 25 and has a side inlet 26 to the cylinder below the piston 28. The bored end of the rod 24 takes over a small central projection 27 in the cylinder head. A heavy load, if of short duration, will be held from rapid opening of the arms 12 by the slow leakage through the head valve 29. If of sufficiently long duration to permit the head of the rod 24 leaving the projection 27, a rapid flow through the bore 25 will be permitted and the bight 37 will rise to turn a switch lever 38. The grooves in the wheel rims are set at an angle to enable the hanging portions of the ropes 16, 17 to clear the bight 37. In a modification the cylinder 22 is connected to further links pivoted to one another and to the arms 12, and in one form these links may be scissors crossed and the cylinder 22 and piston work against outer compression.

Title: A process for the production of thioethers
Inventor: HAHN WILLI
IPC: C10L1/24
Filed: 1961-04-19
Abstract: Thioethers are prepared by heating an aliphatic, aromatic or heterocyclic mercaptan with an ethylenically unsaturated hydrocarbon, for example, ethylene, propylene, isobutylene, nonylene, cyclohexene and styrene, in the presence of a mercaptide of a metal of Periodic Group I to III.  Aliphatic, aromatic and heterocyclic mercaptans such as dodecyl mercaptan, thiophenol, p-thiocresol, or 2-mercaptobenzthiazole, or halogen, alkoxy, nitro or amino substituted derivatives thereof are used.  The metallic mercaptides preferably use the mercaptan to be alkylated, and may be prepared in situ.  The mercaptide is added to the mercaptan and the unsaturated hydrocarbon, optionally in an inert solvent, or in an excess of unsaturated hydrocarbon.  Examples describe the preparation of ethyl phenyl sulphide, ethyl-(2-ethyl phenyl)-sulphide, isopropyl phenyl sulphide and isopropyl-(isopropylphenyl) sulphide, n-propyl phenyl sulphide, t-butyl-p-tolyl sulphide, t-butyl-p-tolyl sulphide, isobutyl dodecyl sulphide, nonyl phenyl sulphide, cyclohexyl phenyl sulphide, 2-propyl mercapto benzthiazole, t-butyl phenyl sulphide, dodecyl-(b -phenyl ethyl) sulphide, isopropyl-(p-chlorophenyl) sulphide, and isobutyl phenyl sulphide using mercaptides prepared from aluminium, sodium, potassium, magnesium, and calcium.  The products are suitable as antioxidants and stabilizers and additives for fuels and mineral oils, and as intermediates.

Title: Improvements in and relating to the storage and utilisation of heat
IPC: F24C15/34
Filed: 1931-05-14
Abstract: 385,294. Heat - storing apparatus. SZIKLA, G., 52, Budafoki-Ut, MERSE, P., 7, Arpad-Utca, and VAGO, P. VON, 52, Budafoki-Ut, both in Budapest. May 14, 1931, No. 14324. [Class 64 (ii).] Electrically generated heat is stored in a body of metal or ceramic material, or a fusible salt, and the stored heat is conveyed to the point of utilization by a liquid heat carrier of high boiling point moving in a regulable manner by means of thermo-siphon action. The heatstoring mass I may be placed in an evacuated casing 4 which may contain heat-reflecting sheets 6 and may be surrounded by insulating material 16. The liquid heat carrier which may be mercury, passes through a pipe-coil 7 to the point of utilization 9. An inverted U-tube 10 is interposed in the circuit through which liquid can only pass by overflow at the highest point. This tube is connected by flexible tubes 11, 13 to a vessel 12 which is movable vertically to regulate the level in the descending branch of the U-tube. The rate of circulation of the heat carrier by convection varies with the height h which is regulated by moving the vessel 12, and the temperature in the oven 14 is correspondingly regulated. In a modification, Fig. 2, the liquid circuit is connected by a pipe 19 to an airtight air-cooled vessel 20 surrounded by a heating coil 21 which is energized by a relay 23 controlled by a thermostat in the oven 14. The space 20 contains a small quantity of water, which vaporizes when the thermostat causes the coil 21 to be heated, and the pressure forces the mercury downward in the tube 19 and consequently causes an overflow in the U-tube 10, so that more heat is conveyed to the oven 14. In another modification, Fig. 3 (not shown), several heat consumers are supplied from a common heat accumulator through separate inverted U-tubes, each of which is connected to an electrically-heated vessel containing inert gas for controlling the overflow of mercury in the U-tube, and an additional similar vessel may be provided by which all the consumers may be controlled simultaneously. The heat storage mass 1 may alternatively consist of potassium or sodium nitrate, the solidification point of which lies between the extreme working temperatures, or a material the decomposition of which is a reversible reaction within these temperatures.

Title: Improvements in or relating to television systems

Filed: 1958-05-08
Abstract: 871,597. Secret transmission. RANK ORGANISATION Ltd. May 7, 1959 [May 8, 1958], No. 14752/58. Class 40 (4). [Also in Group XL (b)] In a transmitter for a subscription television system, Fig. 1, the signals are rendered secret by separating the video signals into a low- and a high-frequency band, modulating the lowfrequency band on a sub-carrier from a source 8 in a modulator 7, developing the high-frequency band in opposed polarities by a phase-splitter 9 and then selecting one or the other polarity by a switch 10 controlled by coding signals applied from source 12 via a bi-stable circuit 11, and finally combining the resulting signals from 7 and 10 in an adder 13 for transmission. The separation of the video signals into bands is effected by first selecting the low-frequency band by means of a channel including an inverter 2 and suitable low-pass filter 3 and then subtracting the low frequencies from the whole band of the original signals by adding the inverted low frequencies to the original signals in an adder 6. The channel for the whole band of the original signals includes a circuit 5 to equalize the delay of filter 3. The preferred lowfrequency band is 0-200 kc/s., and the preferred frequency for the sub-carrier is of the order of 1.25 mc/s. and also an odd multiple of half line frequency. The coding signals cause the polarity selection of the high-frequency band to be effected in a random manner and may be derived and communicated to receivers by the methods described in Specification 841,627 and Specification 850,824. The lowfrequency band is preferably modulated on the sub-carrier in negative polarity. At a cooperating receiver, Fig. 2, the sub-carrier is selected by a selective amplifier 2 and demodulated at 25 to obtain the low-frequency band, whilst the received signals are also derived in opposed polarities by a circuit 23 and the outputs applied to a switch 24, which is controlled by decoding signals applied from 28 via a bistable circuit 27, so as to re-establish correctly the polarity of the high-frequency band. A network 29 equalizes the delay via amplifier 22. The re-established low- and high-frequency bands are combined at 26 and applied to the television display.
