Title: Improvements in and relating to faceting machines
IPC: H02P5/50
Filed: 1980-01-21
Abstract: In a faceting machine the workpiece to be faceted (10) is rotated by a first motor (16) at a speed which is related to the speed of rotation of a cutting tool (44) driven by a second motor (40). The speed of the first motor is controlled by a circuit (22) a control signal for which is derived by a tachometer (18) associated with the motor (16). A second signal for comparison with the first signal may be derived from a constant voltage source (26) or a varying voltage source (28) or may be derived from a second tachometer (38) associated with the motor (40). Alternatively a combination of signals may be used to derive the signal for comparison in circuit 22.

Title: Laundry bags
IPC: D06F95/00
Filed: 1980-04-10
Abstract: A bag 58 for contaminated laundry is formed of a hydrophobic or water-insoluble sheet material, the edges of a medial slit in a bag wall 20a being joined or bridged by an overlying layer of water-soluble or water-dispersible material 26 secured to the sheet material by strips of adhesive 38a, 38b.

Title: Mixed exhaust and bypass turbofan aeroengine
IPC: F02K1/38
Filed: 1981-03-14
Abstract: A turbofan aeroengine 1 is of the type in which the turbine exhaust stream 23 and the bypass exhaust stream 17 are mixed together within the engine before issuing from the propulsion nozzle 15 as a propulsive jet 25. Streams 17 and 23 are brought together for mixing at the downstream end of a mixer ring 13, stream 17 having a swirl velocity which is opposed to that of stream 23 and an axial velocity which differs in magnitude from that of stream 23. This produces circumferential and axial shear between streams 17 and 23 resulting in the formation of stream-mixing vortices which originate at or near the trailing edge of the mixer ring 13. The mixer ring can be modified in various ways to facilitate control of the vorticity. <IMAGE>

Title: Colour television systems
Inventor: CLARKE CHRISTOPHER KEITH PERRY
IPC: H04N7/06
Filed: 1981-12-23
Abstract: In a colour television signal the luminance signal is modulated onto a subcarrier so as to occupy a frequency band above the chrominance band. The frequency spectrum comprises the sound signal modulated to occupy the lowest portion (1.5 MHz for 625/50 PAL System I), the chrominance signal modulated on a subcarrier of two-thirds of the existing conventional colour subcarrier (2.9 MHz), and the luminance signal modulated on what is currently the conventional colour subcarrier frequency (4.43 MHz). The whole signal occupies 10 MHz and is suitable for f.m. transmission such as for satellite broadcasting. As well as a coder (Figure 4) and a decoder (Figure 5), a transcoder (Figure 6) can be provided using frequency shift circuits to adapt a conventional receiver to the transmitted signal. <IMAGE>

Title: Detecting surface defects in workpieces
IPC: G01N21/88
Filed: 1982-02-08
Abstract: The detection of surface defects in mechanical parts is effected by the analysis of diffracted light coming from these defects. The detection method includes the steps of illuminating the surface (S) of the part to be examined with incoherent light and forming a flat image of the said surface in a transparent photosensitive layer of a spatial light modulator (14). The spatial distribution of the intensity of the incoherent light reflected by the said surface (S) produces a corresponding and proportional spatial distribution of values of refractive index in the photosensitive layer. This layer is illuminated with plane polarized, coherent light by frame scanning in elementary areas. During the scanning operation, the variations in at least one of the polarization components of the coherent light are detected by a matrix of converters (42) after the light has traversed the said transparent photosensitive layer. <IMAGE>

Title: Tractor implement hitch control system
IPC: A01B63/111
Filed: 1982-02-11
Abstract: A tractor implement hitch control system is selectively settable by the operator to operate in "draft control mode", "position control mode" or "intermix mode" in which a combination of signals from the draft force and the position sensing units is used. Electric signals are received from sensing units 25, 33 indicative of draft force on and position of the hitch respectively. When the system is operating in the intermix mode a number of discrete intermix ratios (D1, D2) are available which can be alternatively and predictably selected by the operator. In a preferred form of the invention a common control member (36) selects either pure position control (P), or pure draft control (D3), or one or more predetermined and discrete intermix ratios (D1, D2). This control member (36) can also be used to switch the system off and to select the transport position (T) of the hitch. <IMAGE>

Abstract: A tumbler dryer comprising a tumbler (1), a heater (17), ducts (2, 3) for intake and exhaust of air, a ventilator (4), and a filter (26), comprises in addition a modularly built air recirculation part (8). This part comprises a two-sided centrifugal ventilator (14a) mounted in the recirculation duct (14). The actuating motor (14b) of the centrifugal ventilator is mounted outside the duct (14) and the outlet dampers (10, 11) opening to the ambiency and the recirculation duct (8), respectively. The dryer furthermore comprises an extra dust filter (25) located within the duct immediately in front of the heater (17). The dampers (10, 11) are forcibly controlled by automatic control means (15, 16) co-operating with a program device (18) associated with the tumbler (1) and the heater (17). This control is such that the dampers (10, 11) together and preferably in any position form a substantially constant flow area. In this manner a particularly reliable dryer is obtained which reduces considerably the consumption of energy during a tumbler drying process. <IMAGE>
