Title: Telephone receiver call device - has magnetic cassette with tape to give pleasant and continuous sound or recorded music
IPC: H04M19/04
Filed: 1975-03-04
Abstract: A call bell or buzzer of a telephone receiver may be replaced by another call device with a harmonious and continuous sound. The call device has a magnetic tape cassette. The cassette has pre-recorded music or other sounds according to choice and the device uses the voltage supply to the bell to switch on the cassette. The call signal is injected acted into a transformer and the output of the transformer is connected to a rectifier. The signal is then filtered by a capacitor to obtain DC at 15 volts. This voltage excites a relay which can switch-on the supply to the cassette. The value of the capacitor is chosen to maintain continuous excitation of the relay. A push-button is used to discharge the capacitor and to reset and relay when the receiver is lifted off the telephone.

Title: Multi stage epicyclic gearbox - has interstage bearings repositioned for reduction in overall length
IPC: F16H1/46
Filed: 1975-07-25
Abstract: A multiple epicyclic gear train of very compact construction has an input shaft (5) driving a plate (11) carrying a pinion (32) which meshes with an outer ring gear (40) and a central gear (6) coaxial with the drive shaft. This central gear is then the input drive to the next stage and so on. The reduction in length in this design is achieved by eliminating the bearings carrying the central gears and normally placed between each stage. Instead the sattelite carrier plates (11, 12, 13, 14) are each made either from two plates with the facing peripheries chamfered, or from one plate with a peripheral groove. The chamfers or groove then form tracks for peripheral ball bearings (56-63) which run in similar tracks in the outer casing (2).

Title: Zircon colours prodn. - from aq. sodium zirconium silicate suspension and mine ral acid by reaction in free fall, preventing corrosion
IPC: C09C1/00
Filed: 1975-10-10
Abstract: In the prodn. of zircon colours by reacting aq. Na-Zr silicate (I) suspensions, opt. contg. colouring additives (II) and/or mineralisers (III), with mineral acids (IV) to produce a crude colour (V), followed by calcination, the aq. suspension and (IV) are mixed without coming into contact with a boundary wall and reacted during free fall to produce (V), before calcination. The prods. are used widely for colouring ceramic glazes and compsns. This method of mixing is simple and avoids the problems of corrosion and erosion occurring when small mixers and high turbulence are used.

Title: Initiation of carbon monoxide oxidn. - in fluid catalytic cracking regenerators by increase of coke content of regenerated catalyst and then of air flow rate
IPC: C10G11/18
Filed: 1975-11-13
Abstract: Initiating the oxidn. of CO to CO2 in a dense-phase catalyst bed in the regeneration zone of a fluid catalytic cracking (FCC) unit comprises (a) contacting the spent catalyst with fresh regeneration gas (pref. air) to reduce the coke content to a 1st value (pref. 0.1-0.6 wt.%) and produce a CO-contg. regeneration gas; (b) increasing the coke content of the catalyst to a value 0.1-0.5 wt. % higher than the 1st value (pref. 0.2-0.8 wt. %) and maintaining this coke content until a constant dense-bed temp. is reached; and (c) increasing the flow rate of the fresh regeneration gas to reduce the coke content of the catalyst to a value below the 1st value (pref. 0.01-0.09 wt. %) and to oxidise CO to CO2. Increasing the coke content in step (b) increases the supply of fuel which, when the air flow rate is increased, increases the temp. in the dense phase to a level (677-760 degrees C) at which CO oxidn. is initiated; once initiated, the exothermic oxidn. proceeds spontaneously. This prevents post-combustion in the dilute phase, allows part of the heat of combustion to be recovered, and prevents CO emission into the atmosphere.

Title: Vertical dry distillation retort - producing coke from briquetted coal in two coking zones in temp steps
IPC: C10B1/04
Filed: 1976-01-16
Abstract: In an internally heated vertical dry distillation retort for the continuous production of coke from briquetted coal, the charge is subjected to a first coking process in a first zone of the retort by heating gas at a temperature of 550-650 degrees C. The semicoke produced thereby undergoes a second coking process in a second zone of the retort by heating gas at a temperature of 900-1100 degrees C. A part of the gas produced in the second zone is introduced to the first zone as complement to the heating gas. This produces coke of metallurgical quality from low-grade caking and non-caking coal. Environmental pollution by soot and fumes during the discharge and quenching of coke are eliminated.

Title: Commutation circuit for three-phase rotating machine - uses initial current pulse subdivided according to current diagram (SW 6.3.78)
IPC: H02M7/527
Filed: 1976-08-24
Abstract: The commutation circuit for a three-phase rotating machine, e.g. forming part of an electric traction system, supplies the machine with individual current pulses obtained by sub-dividing the initial 120 degree current pulses for each phase supplied during each period. The individual pulses are formed by intersecting the surfaces of the current diagram as a function of time a according to limit functions defined in terms of the angular frequency, so that, for each 120 degree current pulse, the machine receives at least three individual current pulses.

Title: Hydraulically operated rock drill - has cutting edge raised after each axial travel and part rotated to prevent jamming in cracks in rock (SW 13.3.78)
Inventor: KOLLANDSRUD PER
IPC: B25D9/12
Filed: 1976-09-09
Abstract: The rock drill is hydraulically operated and has its cutting edge (12) fixed directly (11) onto the operating spindle (9) passing through the drill body (5). The operating fluid enters at the top, through a rotary motor (2). The outlet fluid then passes (3) into a chamber and up axial slots (7) to drive the spindle down. This hydraulic fluid is exhaust (8) from the machine whilst a further portion is conducted (4) to the underside (6) of the operating piston. The difference in pressures raises the drill and the combined effect of lifting the tool between blows and part rotating it prevents jamming in cracks in the rock.

Title: Ceramic heat exchangers for use at high temps. - made of combined refractory and gas-impermeable materials
IPC: F28F21/04
Filed: 1977-03-10
Abstract: Ceramic heat exchanger for use at temp. up to 1400 degrees C (e.g. in gas turbines) consisting of crosswise stacked plates provided with parallel, multiple ducts for the liquid or gaseous heat-exchange media is improved in that it is assembled by the module method. Elementary plates are produced by extrusion using different ceramic compsns.; then dried and opt. fired. The plates are then stacked in such a manner that the ducts in each plate are positioned at the right angle with respect to the ducts in the adjacent plates. The plates can be then sintered together. The cold and hot media flow crosswise through the alternating rows of ducts. Effective heat exchange is ensured because materials having high thermal conductivity can be used and the wall thickness is small (0.2-5 mm). Materials having good corrosion resistance at high temps. can be combined with gas-impermeable ceramics or metal foils. The assembly is resistant to temp. shocks.
