Title: A timer or time signal transmitter with a CMOS circuit
IPC: H03K3/03
Filed: 1978-12-22
Abstract: Frequency adjustment or variation is achieved by means comprising a time-determining RC device between an output 3 of the CMOS circuit and a control input 4, with a second time- determining resistor R2 being connected to a connection between the resistor R1 and the capacitor C of the RC device. In order to enable frequency control to be varied within wide limits with simple switching or circuit means, provision is made for the charging and discharging process of the capacitor to be effected via different resistors. For this purpose, a diode is connected into or with the RC device, as shown, between the capacitor and the resistor thereof, whereby only one direction of current flow occurs in the charging branch. By appropriate resistance dimensioning, a pulse sequence with a very high keying ratio can be achieved. In Figure 1, when VDD is present at output 3, VSS occurs at control input 4, diode D1 conducts, and R1 is effective as a time-determining device. After changeover of S, VSS is applied to 3, VDD is present at 4, D1 is blocked, R1 is ineffective, and instead R2 is effective. In a modification, S includes a frequency divider. <IMAGE>

Title: Method and Apparatus for Determining the Quality of Oriented Polymeric Materials
IPC: G01N21/47
Filed: 1979-01-10
Abstract: A method of determining the quality of oriented polymeric materials, based on the effect of small-angle scattering of polarized light, involves the passage of a beam of monochromatic, polarized and collimated light through an oriented polymeric material, extracting the scattered reflections, converting them to a train of electric pulses, and determining the degree of orientation of the material using the pulse spacing. An apparatus comprises a source (1) which produces a beam of monochromatic, polarized and collimated light passed through an oriented polymeric material (2), and a housing which accommodates an analyzer (4) formed of polarising material, a mask (5) and a unit (6) to convert the scattered reflections passed by the mask (5) to a train of electric pulses. The scattered reflection converting unit (6) comprises a scattered light detector (7) coupled to a recorder (8). The apparatus of the invention can find use in chemical, textile and other industries utilizing polymeric materials. <IMAGE>

Title: Electric liquid heating containers
IPC: A47J27/21
Filed: 1979-05-01
Abstract: An automatic electric kettle or the like has an automatic cut-out operated when the kettle boils or when the kettle is energised without sufficient water. The automatic kettle includes a thermal detector (23) of shape memory effect material operating a switch mechanism (17-33) and connected to the kettle wall (12) or the kettle element (14) through a heat conductor (43) having a temperature gradient along its length, whereby it may detect a "boil-dry" condition.

Patent GB-2024249-A (GB)
Title: Pneumatic tire having a lubricant on its interior surface
IPC: C10N50/08
Filed: 1979-05-16
Abstract: To facilitate relative movement between the internal surfaces of a pneumatic tire which come into contact when the tire is run in a deflated condition, the interior of the tire is coated with a lubricant which does not flow at normal tire operating temperatures. The matrix of the lubricant is a polyester, polyurea or polyurethane which does not begin to flow until the tire reaches a temperature of from 65 DEG C to 150 DEG C. If the lubricant were allowed to flow at operating temperatures, it would adversely effect the balance and performance of the tire. The high tire temperature indicates that the tire is flat and reduces the viscosity of (liquifies) the lubricant causing it to flow. The lubricant then reduces rubbing friction and temperature rise which would otherwise occur by rubber-to-rubber contact. The lubricated tire can be run flat to a service station.

Title: Improvements in determining the dimensions of workpieces
IPC: G01B11/04
Filed: 1979-05-17
Abstract: The width and/or the thickness of a workpiece is measured by using T.V. cameras, which have photo diode arrays, to view a plane of the workpiece 3 at two positions 1, 2 displaced vertically above a datum. The resulting signals indicative of the angle subtended by the workpiece at the image positions are representative of the image widths Wa1 Wa2 apparent at these positions. These signals are fed to a microprocessor (Fig. 2) where the two "apparent" width signals are combined, to provide product and difference components that are used to calculate the true workpiece width and/or the workpiece thickness by using disclosed formulae. <IMAGE>

Title: A Programmable Timer
IPC: G04G15/00
Filed: 1979-05-25
Abstract: A programmable timer for individual control of a plurality of control functions comprises a switch for each of the functions, each switch being settable by respective setting elements so as to be actuated at predetermined on and off time, and separate indicators 13, 14 which provide a simultaneous indication of the on and off time settings of the respective switch. As shown the indicators 13, 14 are coupled to the sliders of linear potentiometers the output voltages of which are fed to respective D-A converters (26, Fig. 2 not shown). The corresponding switch is actuated when a digital comparator (25) detects coincidence between the value in the converter and the time of day as shown by a display 11. Alternatively the time of day is converted to an analogue value which is fed to comparators (36, Fig. 3 not shown) which each also receive the output of a respective potentiometer. The timer shown controls hot water, central heating, and an oven. <IMAGE>

Title: Coaxial bowl and stem
IPC: A24F1/28
Filed: 1979-05-30
Abstract: A device for use in smoking tobacco having a stem, 1, 2, and a burning chamber 3 co-axial with the stem and open at the end. A cap 4 overlies the burning chamber. Tobacco is inserted into the burning chamber through the open end if the cap is removed, or through an opening in the end of the cap, which opening is then closed by a movable disc. The tobacco is provided in the form of a tube which contains a quantity of ready-rubbed slow burning tobacco. The tube is aluminium foil. The smoking device avoids the disadvantages of known pipes, i.e. filling with loose tobacco and cleaning of the bowl (i.e. burning chamber). The device also avoids the appearance of a pipe and is, therefore, more socially acceptable to women who may wish to smoke tobacco and to people generally who wish to find a substitute for cigarettes. <IMAGE>
