In the UHF tuner shown in Figs. 2 and 3 rotation of channel switching shaft 2 through 180 degrees covers the whole UHF television zone by rotation of a variable condenser gear 107 via gears 106, 103 and 104. The channel positions as determined by a switching cam 109 having ten cam projections 110. The shaft 2 is in friction drive with the gear 106 and switching cam 109 by a washer 111. Fine tuning is obtained by rotating a shaft 4 which rotates gear 106 by means of gears 112, 114, 116 which co-operate to move a pin 113 of the gear 106 within a slot (117, Fig. 4, not shown) in the switching cam 109. The channel indicator 3 is driven by a gear 6 which is coupled by a shaft 5, a dial shaft 115 and three pins 118 to the switching cam 109. An indicator drive shaft 12 is rotated 1/10 turn by gears 6 and 13 for each divisional rotation of the channel switching shaft 2 and the first digits 29 are indicated by a drum 27 which is coupled by a boss 28, Fig. 6A, to a shaft 16 of the indicator drive shaft 12. The second digits 25 are indicated by an outer drum 22 which is rotated 1/10 turn for each turn of the indicator drive shaft 12 by an intermittent feeding gear 19 having teeth 20 and 21 of alternately different lengths which cooperate with tooth shaped portions 14, 15 on the indicator drive shaft 12 and with an internal gear 23 in the base of the indicator drum 22. The indicator drums 22, 27 have transparent portions 26, 30 and digits 25, 29 which may be illuminated by a light placed inside the drum 27. The digits may not be printed and a film, tape or the like carrying the digits may be wound round the drums. In a modification (Figs. 7 and 8, not shown) the axes of the drums (33, 34) are mounted horizontally to the tuner and each drum has two peripheral portions providing transparent portions (37, 38) and digit portions (35, 36).

Patent GB-2026552-A (GB)
Title: Machine for spot cleaning a fabric workpiece
IPC: D06F43/00
Filed: 1978-08-02
Abstract: A portable machine for dry-cleaning fabric workpieces particularly for removing spots and stains from cloth, comprises a suction nozzle (15) associated with a horizontal screen (16) on which the workpieces are laid. A tool (28) supplies a controlled flow of liquid to the workpiece. The tool face which engages the workpiece has a central orifice surrounded by an imperforate shield which prevents the outward spreading of the liquid when the tool is pressed down against the workpiece. This combined with the suction nozzle (15) ensures the liquid supplied to the workpiece over the selected area to be cleaned is rapidly withdrawn through the suction nozzle (15) before it can spread over and beyond the selected area. The machine is housed in a casing (10) containing a water tank (23) and a pump (25) for supplying the controlled flow of water to the tool, and a motor and fan (11) for furnishing the suction to the nozzle (15). The machine may also include a downwardly directed blowing nozzle (18) connected to the pressure side of the fan and situated above the screen (16) for drying the workpiece. The airstream serves to cool the motor and the latter in turn heats the air. <IMAGE>

Title: An interpolating circuit for raster graphical display
IPC: A61B5/0432
Filed: 1978-11-22
Abstract: An interpolating circuit provides an image curve on a raster-type graphical display which approximates to a continuous curve, lengthening the points in the raster line direction, by taking into account the previous and present discrete values to be displayed. On a CRT scanning vertically the electron beam is brightened when the beam reaches the amplitude of the smaller one of the two considered neighbouring values and the brightness is maintained until the beam amplitude becomes higher then the greater one of these two values. For this purpose, the interpolating circuit comprises horizontal and vertical counters (9, 8) under clock 10 control; two storage (1, 2) registers, the first (1) reaching from data storage (11), the second (2) reading from the output of the first (1); two comparator units (3, 4) and a logical network, (5, 6, 7) which controls the beam brightening at (16). <IMAGE>

Title: Measurement of the Brightness of Milled Products
IPC: G01N21/47
Filed: 1979-10-01
Abstract: The surface 8 of a layer of flour is illuminated from a lamp 1, and a reflected intensity of light 5 is detected by transducer 7. In Fig. 1, the light beam from the lamp is optically split at 3 into a reference beam 4 and measurement beam 5. The measurement beam is cyclicly chopped by a rotating drum shutter in such a way that only the reference beam will strike the transducer during a first measurement phase, and during a second measurement phase both reference and measurement beams will be applied to the transducer. The output signals of the transducer are stored in memories 13, 14 so that both output signals can be taken simultaneously to an evaluating device 15, 16 for determination of the relative brightness value of the measurement beam in comparison to the reference beam. In the arrangement of Fig. 5, the chopper drum construction is such that measurement and reference beam intensity signals are obtained individually. In the arrangement of Fig. 6, both beams are chopped such that the respective signals are again obtained individually but separated by periods in which both beams are blocked and background light is sensed. The brightness measurement can be used in a method of measuring and/or monitoring the homogeneity of a batch of flour in which a plurality of streams of product from the batch are formed and recombined, the brightness of each stream being measured and homogenization being continued until the desired brightness is obtained. <IMAGE>
Patent GB-2038183-A (GB)
Title: Polymeric fragrance materials and processes for their manufacture
IPC: A01N25/18
Filed: 1979-10-23
Abstract: The invention provides a sealed product comprising synthetic hydrophilic polymer compositions containing a volatile active material which is released on exposure to the atmosphere which are wrapped in a transparent film which is impermeable to water vapour. These products exhibit a lesser tendency to exude the volatile material even on prolonged storage as compared to previously known products which were wrapped in polyethylene films. In a preferred form these products are produced by preparing a blister pack from any suitable wrapping material and using this as a mould into which the monomers are poured and then polymerised. Such products are readily adapted so as to be sold without further packaging or decoration.

Filed: 1979-10-25
Abstract: In a video disc player, a carriage 208 is subject to translatory motion in correlation with radial motion of a play- back stylus 202 relative to a disc record disposed on a rotatable turntable. A stylus arm 200 carrying the stylus 202 at one end thereof has the other end secured to the carriage 208 by means of a compliant e.g. rubber coupler 206. A magnetic element 210 is disposed on the stylus arm near its free end. An electromagnet 212 is fixedly mounted in the carriage 208 adjacent to the stylus arm-mounted, magnetic element 210. The electro-magnet is selectively actuated by a winding 220 to cause a change in the radial location of the stylus, whereby tracks may be skipped forward or backward. <IMAGE>

When the valve is opened the plate and sealing strip 22 are retracted from the bore through the housing 4, thus allowing material to pass through the valve without eroding the sealing strip 22. The plate and strip 22 pass through a stuffing box 34. A topworks housing 38 completely encloses and protects the plate 14 when the valve is in the open position and includes windows for observing the valve position and a universal adaptor plate 48 for accommodating any suitable actuating device. The plate is guided by spaced projections 16 on opposite sides of the plate. <IMAGE>
