Title: Inner ball race rings automatic prodn - on multi-station machine with single drive motor
IPC: B21D53/10
Filed: 1971-10-20
Abstract: Inner ball race rings are cut from a length of tube and formed in a pressing operation on a single machine. A crank shaft drives two horizontally opposed dies through a connecting rod and toggle mechanism at half the speed of a device for shearing the correct length of tube, with a mandrel inside it, and lowering it into the pressing position. The same drive is used with different gear ratios for all parts of the machine including tube feed, mandrel removal, and return to cutting station.

Title: Appts for conditioning wax - by air free passage into an injection ch
IPC: B29C67/24
Filed: 1971-10-27
Abstract: The apparatus has an air-tight reservoir formed from a material of high thermal conductivity, provided with openings for the introduction of solid wax and a removable air-tight cover blocking the openings. The reservoir has heating and agitating means and vacuum can be applied to it. The lower part of the reservoir is connected to the upper part of the injection vessel which is in the form of a hollow cylinder with a piston. The flow of wax is controlled by a valve. The use of wax free from air makes patterns of improved surface quality in the lost wax process.

The fins may take the form of diametrally opposed segments.
Patent FR-2121873-A1 (FR)
IPC: G10L25/00
Filed: 1972-01-14
Abstract: 1339173 Selective signalling ELLIOTT BROS (LONDON) Ltd 15 Jan 1971 2011/71 Heading G4H A data handling system responsive to the frequency spectrum of an input, converts the input into a rectangular waveform having two amplitudes, one of which operates a counter, a less significant part only of the count being sampled periodically and transmitted (or only a single less significant digit of a count may be actually accumulated in the counter). In a system disclosed, an electrical waveform from a sound transducer is amplified, band-pass filtered and then clipped to a rectangular waveform which switches amplitudes at the zerocrossings, to gate clock pulses from a pulse generator to a counter. The count is periodically sampled by the pulse generator acting through a frequency divider, with or without subsequent resetting of the counter, and the counts are transmitted to a receiver at which each is converted to an analogue pulse amplitude. These pulses are lengthened to give a stepped analogue waveform which is fed to a bank of filters. As a modification forming an embodiment of the invention, only one stage of the counter has its state sampled and transmitted (the counter not being reset after each sampling). Alternatively, the rectangular waveform may simply switch a flip-flop, the state of which is sampled and transmitted. The frequency may be increased by a frequency changer before the band-pass filter. The total amplitude of the energy received by the transducer could be signalled by inserting a frequency modulator before the bandpass filter to give an amplitude to frequency conversion, or a reference signal could be added at this point so that the transmitted information represents not only the relative amplitudes of the various frequency components received but also their amplitudes relative to the reference signal, from which the overall (total energy) amplitude may be derived at the receiver. The receiver may alternatively be a digital computer with a Fast Fourier Transform programme. Another embodiment has a ring of 8 sound transducers feeding respective channels, the count signals in the different channels being sampled in turn, transmitted, and distributed at the receiver to 8 output channels each of which delays the signals received and feeds weighting and summing units in all the output channels from the delay, the delaying, weighting and summing being such that the output in each channel, obtained via a band-pass filter, represents the total sound energy received by the ring of transducers from a respective direction, and contains frequency spectrum information for that direction. Application to radio (instead of sound) is mentioned.

Title: Cement raw meal agglomerator - comprises a twin fluid bed reactor and utilises the accruing fly dust
IPC: B01J8/00
Filed: 1973-10-02
Abstract: The agglomeration reactor for fine dust feed for clinker firing comprises two fluid bed zones. One of these is near the discharge and is used for the prodn. of the correct final grade material whilst the other opposite to the outlet is used to replenish the second bed with chemically reacted material. These zones are separated by a weir or simply as the result of separate operating modes for the two fluid beds. Sufficient material has to be transferred from the first into the second zone to maintain prodn. of laid down characteristic end material. The fly dust accruing is sepd. from the main stream to a dust separator and is reused, the fly dust from the first zone being first fed into the second zone. This results in the formation of fresh small particles which need not be completely transformed. The dust is used to displace the material from the first zone into the second and eventually to the outlet. Chemical reaction however occurs concurrently with these displacement movements. The system permits the use of fine raw meal feed material which cannot normally be used for clinker mfr.
