Abstract: 441,613. Clutches. PULSOMETER ENGINEERING CO., Ltd., and WARREN, R., Nine Elms Iron Works, Reading. April 14, 1934, No. 11335. [Class 80 (ii)] In a roller freewheel clutch, the inner member 3 has limited angular play on the driving (or driven) shaft 4 and the clutch is adapted to be locked by a plate 5 slidable on the shaft 4 and provided with teeth 6 adapted to be engaged with teeth 7 in the outer member 1, which latter is secured to the driven (or driving) shaft 2. Chamfered dogs 12, 15 on the member 3 and plate 5, respectively coact to prevent engagement of the teeth 6, 7 when the driven member of the freewheel clutch is overrunning the driving member thereof. To prevent jamming, the plate 5 is allowed a slight angular play on the shaft 4. The plate 5 is urged towards engagement with the member 1 by a spring and, when the clutch is applied as the tail clutch of a motor-vehicle gear-box, is retracted by over-depression of the main clutch pedal, with which it has a lost-motion connection, the plate being retracted after the main clutch has been disengaged and being released prior to engagement of the main clutch. The plate may have auxiliary manuallyoperated control means which may include means for preventing over-depression of the clutch pedal when desired. Specifications 394,144 and 418,328 are referred to. Reference has been directed by the Comptroller to Specification 435,278.

Abstract: 858,393. Television. WESTINGHOUSE ELECTRIC CORPORATION. April 7, 1959 [April 11, 1958], No. 11731/59. Class 40(3). [Also in Groups XXXVI and XL(a)] The, or each, electroluminescent element 68 Fig. 3 of a solid state image screen for producing light in response to input signals is associated with first and second non-linear dielectric members 62, 66, adapted to be controlled with respect to their effective capacitances by the input signals, in a balanced circuit system with substantially no light power potential appearing across the element 68 when no input signals are applied to the members 62, 66 and these members 62, 66 being effective to unbalance the circuit for impressing a light power potential across the electroluminescent material 68 in response to input signals applied to the dielectric members. As shown in Fig. 2, the electro-luminescent material is in the form of a layer 16 between a transparent conducting coating 14 and elemental electrodes 18, with each of which is associated a control element comprising a U-shaped conductor 20 whose centre 22 is in contact with the electrode 18 with one leg 23 in contact with a first layer 24 of non-linear dielectric material and the other leg 25 in contact with a second such layer 26, bus bars 28, 30 interconnecting the elements 25, 26 and 23, 24 respectively. The other sides of the elements 24, 26 are connected via 20 to individual conductors e.g. 32, 34 for the application of control voltages. The equivalent circuit, Fig. 3, contains a light power potential source 48, 46 connected by means of the bus-bars 28, 30 in each branch, one of the light power sources 48 also having a bias battery 50. The initial balance may be achieved by making the capacitances of the dielectrics 62, 66 the same arid making the source 48 of greater value than the source 46 or by having different unbiased capacitors. Alternatively by having different power sources and different unbiased capacitors, no bias battery 50 will be necessary. The input signal shown as the battery 70 may be a video source and may include a further bias to ensure that the central element operates over the optimum portion of its characteristic.

Abstract: 1,030,131. Heating and cooling vehicles. E. SATZGER. March 27, 1963, No. 12065/63. Headings F4U and F4V. In a method of regulating the temperature in the passenger compartments of vehicles, especially rail vehicles, each compartment is heated or cooled by supplying a basic proportion of heat or supplying cooled air respectively to the compartment at a rate responsive to the external air temperature to maintain a preset temperature in the compartment when occupied by a certain number of passengers and, when more or less passengers than this number are in the compartment, causing the internal temperature thereof to tend to rise or fall, compensating for these changes by supplying additional cooled air or additional heat. In the form shown the apparatus comprises a fan 19 which draws fresh air through an inlet 20 and/or recirculating air from the compartments 29 through an inlet 31 and discharges it into parallel, longitudinal main and auxiliary ducts 25, 28 through respective heaters and coolers 22, 23 and 26, 27. The ducts 25, 28 have respective outlets 36, 35, Fig. 5, through which air flows into the compartment through openings 40 in a cover 39, inducing a recirculatory flow of compartment air through openings 42 to improve the ventilation effect. The temperature of the air flowing in the duet 25 is regulated by an external thermostat controlling the output of the heat exchangers 22, 23 whilst the air flowing in the duct 28 is kept at a constant temperature by the heat exchangers 26, 27. The amount of air issuing from the duct 28 to modify the temperature of the main flow of air is controlled by a damper 34 in response to the internal temperature of the compartment, the damper 34 being arranged so that as it opens the outlet from duct 28 it closes the outlet from duet 25 so that the quantity of air delivered remains substantially constant. An overriding manual control 43 for the damper 34 is provided. In a modification the auxiliary heat is provided by electric steam or hot water convectors in the compartments.
