Title: Curve milling or curve grinding machines
IPC: B23Q15/24
Filed: 1972-12-21
Abstract: 1420620 Copy-milling and grinding machines A SCHMERMUND 4 Dec 1973 [21 Dec 1972] 59031/72 Headings B3K and B3D In a modification and improvement of the curve milling or grinding machine of patent Specification 1,354,256 for forming cam discs or cylinders, wherein workpiece 30 is rotated by motor 34 and a pulsed signal indicating the amount of angular displacement of the workpiece is emitted from generator 36 and fed to a single, 50, or a plurality, 40-43, of frequency divider devices where the signal pulses are divided by each device and fed to a tool feed arrangement whereby the tool 16 is fed for a period dependent on the frequency dividing factor and at a displacement dependent on a template, the signals from the frequency dividers are in this case not fed directly to the stepping motor, 109, Fig. 1, 309, Fig. 2, or similar incrementally controllable drive means to move a coupling member (lever 26, Fig. 1, wedge 313 and lever 326, Fig. 2) which corresponds to a template and the movement of which is sensed by feeler 22 and transmitted to tool 16. Instead, the signals are passed to and operate the readout means of an information storage means, such as magnetic or perforated tape unit 101- 105 from which are extracted predetermined coded signals which are fed to translator 107 which controls the movement of motor 109, 309. This provides a more versatile arrangement for controlling the form of the cam profile. Further adjustments may be made by altering the relative positions of feeler 22 and coupling member. The signal generator may be electrical, pneumatic, hydraulic or even optical.

Title: Ultrasonic mobility aids
IPC: G01S15/18
Filed: 1970-12-18
Abstract: 1379541 Ultrasonic ranging ST DUNSTAN'S 20 Dec 1971 [18 Dec 1970] 60284/70 Heading H4D  An ultrasonic pulse-echo distance indicating device transmits pulses at a predetermined rate and the echo receiver is arranged to give an output signal in response to an echo pulse only during periods so timed with respect to the transmission instants that the output signals are provided at a rate which varies with the distance of the echo-producing object from the device. In one binaural blind-aid embodiment clock pulses are fed to a logic switching circuit providing two outputs. One output comprises pulses for triggering or gating anoscillator to periodically energize an ultrasonic transmitting transducer; the other output comprises cyclically recurring trains of pulses for opening receiving circuit gates. Echo pulses of the transmitted ultrasonic pulses are received in two channels. In each channel the output of a receiving transducer is amplified, detected and fed via a gate to an earpiece to give for each gated received ultrasonic pulse an audible pulse of amplitude dependent on the range of the echo-producing object. Fig. 3, shows an example of the timing of the gate-opening pulses. When a first ultrasonic pulse is transmitted at time t = 0 a first pulse 17 opens both receiver gates for a 64 mS period whereby any echo-producing object at a range of up to about 32 ft. will be detected and give an audible click from the earpieces. When a second ultrasonic pulse is transmitted the second gating pulse, 19, of 4 mS duration enables objects up to 2 ft. range to be detected. The third gating pulse is of 8 mS duration, and so on. The result is that in each complete train of gating pulses the number of audible clicks produced relating to an object depends on the object range, being higher at shorter ranges. Other gating pulse sequences are envisaged (Fig. 4, not shown). The transmitting transducer may be hand-held to assist directional location of an object and the receiving transducers are mounted such as to preserve intensity and/or time difference relationships in the two receiving channels.

Title: Aerosol propellant
IPC: C09K3/30
Filed: 1979-04-09
Abstract: The invention relates to a propellant for aerosol spray cans, particularly lacquer spray cans, which is based on the use of carbon dioxide. One difficulty in using carbon dioxide as a propellant is that it is difficult to mix, particularly with a lacquer or similar product. The invention is characterised in that the carbon dioxide is mixed with a propane/butane mixture. Preferably the propellant comprises 20 percent by weight of carbon dioxide mixed with 80 percent by weight of propane/butane mixture. Such a propellant has been found to have no fire risk even though a propane/butane mixture is used and to facilitate mixing of the carbon dioxide.

Title: Improvements in or relating to imaging systems
IPC: G01R33/54
Filed: 1979-11-15
Abstract: In an NMR examining arrangement for producing an image of a region, generally a planar slice, of a body, it has been suggested to derive, from the resonance signals, a plurality of values, for strips in the slice, and then to convolve them with a convolution function to be suitable for back projection in the manner known for x-ray signals. In this invention it is proposed to modulate the resonance signals at 10 with a suitable function from generator 11 and then to Fourier transform them but not to convolve them. The modulation function is chosen to give after Fourier transformation at 6, the same effect as the convolution would have given. It is suggested that the modulation function should be the inverse Fourier Transform of the desired convolution function. <IMAGE>

Title: Control of dc motor speed
IPC: H02P7/29
Filed: 1980-03-13
Abstract: A dc motor 10L, 10R driven by a train of current pulses is controlled by sampling the back e.m.f. generated by the motor during the intervals between said drive pulses, averaging the sampled voltage values in integrator 28, comparing the averaged value of the samples with a second voltage in comparator 22, and varying the mark-space ratio of the pulse train in dependence on any variation in said compared values in a sense to maintain a predetermined rotational speed of the motor. The second voltage is a decaying voltage, and the time at which the decaying voltage equals the averaged voltage value determines the period of the drive pulses to the motor and hence the mark- space ratio of the pulse train. <IMAGE>
