Patent GB-2058614-A (GB)
Title: Controlling machining operation
IPC: B23Q11/00
Filed: 1980-09-11
Abstract: A machining operation, such as drilling, is controlled by sensing heat in the workpiece generated by the operation and comparing a signal significant of this with a reference signal representative of the heat- significant signal that would be obtained in an ideal operation. Deviation of the sensed signal from the reference signal is used to change the performance of the operation. An infra-red sensor 14 or thermo-couple senses the heat. A microprocessor 17 compares this with the reference signal. if the deviation exceeds a predetermined amount over a set period of time, the drill 12 is withdrawn to prevent breakage or to clear swarf. <IMAGE>

Title: Improvements in or Relating to Mobile Radio Receivers
IPC: H03G3/20
Filed: 1982-02-16
Abstract: Fading of a received signal in a mobile radio receiver is corrected by apparatus which includes mixers 21, 22 (Fig. 1) for mixing the received pilot signal with a locally generated signal to produce orthogonal signals I, Q. The signals I, Q are processed by a circuit 28 according to a given relationship to produce signals A, B. The signals A, B are used to modulate the received signal in mixers 15, 16. The outputs of the mixers 15, 16 are combined to produce a signal corrected for fading both in amplitude and frequency. In a further embodiment (Fig. 3) the signals A and B are coupled via modulators 30, 31 to the mixers 15 and 16. The modulators 30 and 31 are modulated by the locally generated pilot signals from 24. <IMAGE>

Title: Method of making a magnetic recording medium
Inventor: YAMADA YASUYUKI
IPC: B05D7/02
Filed: 1982-06-25
Abstract: To make a magnetic recording medium which will not curl at the edges, a non-magnetic support such as polyethylene terephthalate is coated     (a) on one surface with a magnetic coating composition, and (b) on the other (rear) surface with an unsatured compound which is polymerizable by electron beams; the material is irradiated, e.g. from a curtain beam accelerator, at 100 to 1,000 Kv with electron beams at an absorbed dose of 0.5 to 20 megarads so as to polymerize the compound. Suitable polymerizable compounds have at least two -C=C- bonds, e.g. unsaturated polyesters having an acryloyl, acrylamido, allyl, vinyl ether or vinyl thioether group; preferably it has a meth(acryloyl) group on both ends of its straight chain. The magnetic coating may be of ferromagnetic particles also in a compound polymerizable by electron beams, which is irradiated separately or at the same time as the rear coating. An unsaturated -C=C- monomer and/or a thermoplastic resin may also be present in the rear coating. The medium is useful as a video tape, having low curl, low abrasion and good electrical characteristics.
