Title: Improvements in static electrical condensers
IPC: H01G5/06
Filed: 1919-07-11
Abstract: 152,409. British Thomson - Houston Co., and Clinker, R. C. July 11, 1919. Condensers.-A variable condenser is provided with two movable elements connected together by a lost-motion device so that both elements may be operated by the same handle. In the construction shown in Fig. 1, both movable elements co-operate with the same fixed element, which comprises a set of sectors a supported by pillars b set in an insulating-base c. The movable element l, serving the purpose of a fine adjustment, comprises a single sector carried by a sleeve m which is secured to a member n provided with upwardlyprojecting extensions o, to one of which the operating head or handle p is secured by a set-screw. The main movable element comprises a set of sectors e carried by a spindle f to which is pinned a boss k carried by a plate h fixed to the main scale-disk g. The boss k is connected to the plate h by arms q, Fig. 3, in such a manner that ia segmental slot is formed on each side of the boss. The extensions o extend upwardly through these slots so that the head p and sector l can be moved through 90 degrees before the head commences to move the main sectors e. A friction arm r engaging a plate s is provided to prevent movement of the main sectors e before all the lost motion is taken up. The head carries a pointer u co-operating with a scale on the main scale-disk g to indicate the position of the sector l relatively to the main sectors e, and a third scale w is provided to indicate the amount of capacity added when the sector l is turned back sufficiently far to re-enter the fixed element in the opposite direction. Means may be provided for clamping the two movable elements together so that they may be moved as a single element. In one arrangement, Fig. 4, the spindle f extends through the head p and its end is screw-threaded to receive a clamping-nut x. In a modification, a clutch member is depressed against the action of a spring to clamp the parts together, or the head itself may be arranged to be depressed axially against a spring for this purpose.

Abstract: 422,763. Machinery guards. WARD, Ltd., T. W., and ELLIOTT, F., Albion Works, Savile Street, Sheffield. June 13, 1934, No. 17457. [Class 80 (iv)] In machines, such as meat choppers, in which a rotary shaft fitted with blades is journalled on a carrier 5 hinged at 8 to the frame, a guard 21 is hinged at 20 to the carrier and has an abutment 23 which coacts with an abutment 24 on the frame to ensure that the guard can only be opened when the carrier is raised into inoperative position, Fig. III. The act of raising the carrier separates the abutments as shown in Fig. III so that the guard 21 can be moved to the left to expose the blades. The shaft 10 is driven when horizontal through an axially movable dog-clutch, and when the shaft is raised the clutch cannot be engaged. If the guard in Fig. III be turned to expose the blades and the carrier be moved to the right, the motion of the carrier is soon stopped by the abutments though with different contacting places.

Convention dates, June 17, 1933 and March 17, 1934. [Classes 7 (ii) and 7 (iii)] The starting of a cold engine by compressionignition is facilitated by increasing the pressure on the fuel jet by thermal means, which, preferably, is effected by increasing the compression ratio. In Fig. 1 a part B of the combustion chamber is closed by a valve F operated by thermal means J located in the cooling water, and in Figs. 2 and 3 a bowed plate D and a member S expand and open chambers M, Q. The surfaces forming the passage T may have staggered grooves which communicate by ducts with the chambers Q, X respectively, and the member S may be inverted and constitute a pre-combustion chamber. In Fig. 5, a part 5 expands to open a valve 6, a central part 3 being kept cool by water circulating through pipes 4, and in Fig. 6, the expansion of a bridge piece 10, anchored at its ends, lowers a precombustion chamber 9 to the position shown and provides access to an annular chamber 13. As modified in Fig. 10, a member U expands and closes ports b which are additional to the usual ports a giving communication to a pre-combustion chamber ; at starting, air, compressed in the cylinder, thus has better access to the fuel jet.

Abstract: 1,107,813. Decorative panel. C. F. PELLICER and M. F. PELLICER. 26 April, 1965 [12 Nov., 1964], No. 17504/65. Heading B6G. In a method of manufacturing decorative panels, a base 1 is formed by a plane rigid base 2 having a peripheral projecting edge 3 and has applied to it a fluid plastics layer 4 which after vulcanization gives a mirror-like surface. A circular stripe 5 of adhesive material is disposed on the layer 4. A support 6 comprises a frame 7 having a plane front surface and a peripheral hoop 8 projecting from its rear. The support 6 has its front surface placed on the base 1 and is immediately secured thereto by the adhesive stripe 5 so that the support takes on the form of a mould. The mould has poured into it consecutive layers 11 of transparent plastics alternating after polymerization of each such layer with ornamental items 12 such as shells, a final opaque plastics layer 13 being applied to serve as a base for the preceding layers. The support, now a decorative panel, is then separated from the base and a final polishing treatment is given for the external finish of the panel. The base is then used to make further panels. A porous protective edging 9 made of agglomerated material may be secured to the inside of the hoop 8, the inner face of the edging 9 being bevelled. The hoop and frame may be made of a good quality timber such as mahogany. The transparent plastics may be a polyester. The rearward part of the support e.g. the edging 9 may be formed with recesses communicating with the internal space of the support, an appropriate strip of material being positioned to stop such communication, whereafter moulding is effected, and after removal from the mould the strip may or may not be withdrawn or be replaced by another appropriate strip, the object being that the recesses can receive appropriate light. sources adapted to illuminate, either directly or through the strip, the plastics layers 11 and the ornamental items 12. The panels are suitable for the construction of cupboard doors or items such as bars, headboards for beds, wall and roof linings, table leaves. In an alternative method of preparing the decorative panels, the base is dispensed with.

Title: Improvements in or relating to arrangements for regulating the voltage supplied to a load circuit
IPC: G05F1/14
Filed: 1938-06-14
Abstract: 515,948. Automatic control systems. STANDARD TELEPHONES & CABLES, Ltd., THOMAS, P. R., and KELLY, R. June 14, 1938, No. 17674. Drawings to Specification. [Class 38 (iv)] Voltage.-Relates to an automatically controlled system for supplying a load from an A.C. source through a rectifier and tap-changing transformer variable under the control of an electric motor to increase or decrease the transformation ratio automatically in accordance with variations of the voltage across the load by means of a measuring type relay which moves its contact pointer to one contact or another according as the voltage falls or rises. Such a system is described in Specification 514,167. According to the present invention, an auxiliary relay is connected in series on the earth side of the sensitive relay and arranged to open the A.C. supply circuit and give an alarm should a fault develop in the operating circuit of the sensitive relay. A reserve supply may be provided and, when this is in use, a resistance is connected in series with the sensitive relay to raise the voltage at which the relay assumes the mid - position and thereby ensure that the load circuit is not reconnected to the restored main supply until the latter has developed an adequate open-circuit voltage. Further, to meet possible faults in the motor operating circuit a time delay relay is connected in the motor control circuit and is energized whenever the sensitive relay reaches its limit positions but does not close until the tap-changer has had time to move from one extreme position to the other so that normally it does not come into operation. Specification 252,057, [Class 40 (iv)], also is referred to.
Patent GB-582838-A (GB)
Title: Improvements in telephone or like systems
IPC: H04Q3/00
Filed: 1944-09-16
Abstract: 582,838. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BEALE, C. E. Sept. 16, 1944, No. 17737. [Class 40 (iv)] In an automatic trunking system in which through four wire trunk switching is employed at tandem exchanges, local switching at the terminating exchange is done by direct current impulsing through the hybrid transformer which converts the circuit to two wire form. The incoming trunk line TL is connected to an incoming voice frequency relay set, this being controlled by voice frequency signals to which receiver VFR responds. The first digit raises the wipers of the trunk selector ITS to level 1, for local subscribers, and the circuit is connected through to the hybrid transformer HT, impulsing being done by direct current over the two wires which form the direct connection through the hybrid transformer. In an originating exchange the hybrid transformer may not be switched in until dialling has been completed. If the exchange is serving in a tandem capacity, one of levels 2 to 9 of trunk selector ITS is selected and the circuit continues in four-wire form to an outgoing relay set O/G VF. Each outgoing relay set has associated with it a relay BW, which switches over the four-wire connections from an incoming to an outgoing condition, and a relay PS which switches attentuating pads into the circuit in order to maintain the desired levels in the absence of a hybrid transformer.

Patent GB-820174-A (GB)
Title: Voltage regulator, more especially for testing and calibrating installations for measuring instruments
IPC: H02P9/26
Filed: 1956-06-08
Abstract: 820,174. Automatic voltage-control systems. LANDIS & GYR A.G. June 8, 1956 [June 11, 1955], No. 17822/56. Class 38 (4). [Also in Group XL (c)] The output voltage of an alternator is stabilized by the following combination of features. The mean voltage of the alternator G is detected by transformers Tr 1 , Tr 2 , Tr 3  and rectifiers Gl 1 , Gl 2 , Gl 3  which have a load resistance P 4  from which a voltage is tapped off for comparison in valve T 2  with a reference voltage from tube T 1 . The amplified resultant controls paralleled valves T 3  which have the alternator field E in their common cathode circuit. The valves are all supplied from an auxiliary D.C. generator GE. The gain of amplifier T 2  is stabilized against supply fluctuations (see Group XL (c)). Frequency compensation is derived from a tuned circuit Tr 4 , C 3  which applies a corrective voltage to the amplifier T 2 . A portion of the exciter field voltage is tapped off potentiometer P 6  and applied to saturating windings on the transformers Tr 1 , Tr 2 , Tr 3 , to compensate for the effect on the power stage T 3  of the variation in voltage across the exciter winding E. Increase in voltage across winding E reduces the output voltage of the rectifiers Gl 1  ... Gl 3  and so increases the control voltage applied to the stage T 3 .

Filed: 1925-07-13
Abstract: 238,859. Blecher, (nÚe Gebhard), T. Aug. 20, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Colour photography.-A device wherein photographic colour-record images may be registered or produced in register comprises a base-plate F having an aperture over which is supported a fixed or removable glass plate G adapted to support one of four carriers T each held on supports R secured by screw S<1> and nut M<1> to a ledge L resting on the base F. The four ledges, which may be hinged to the base, are mounted adjacent to the four sides of the aperture in the base. In the form shown, the ledges may be displaced between limits over the base before being secured thereto by screw S and nut M. In a modification, the ledges are not so displaceable, but the glass plate G rests on an intermediate apertured plate which may be displaced over, and secured to, the base F. In employing the apparatus, for example to print partial colour record images on paper, the paper is stuck on to the glass plate G, and the blue printing- film T is secured to one of the ledges L. After printing this image, the red and yellow printing- films are secured to two other ledges which are clamped to the base F so that the red and yellow images are in register with the blue image, and these images are printed in superimposition on the blue image. In another example, in which three pigmented gelatin relief images are produced in superimposition, the three colour-record negatives are secured to separate glass plates G. The plate carrying the. blue negative is placed in the apparatus and printed on a blue chromo-gelatin layer T carried on one of the ledges L. After developing the blue image the plate carrying the blue negative is replaced by the plate carrying the red negative, which is registered with the blue image. The blue image layer is then coated with red chromo-gelatin, and the red image is printed and developed. The operations are repeated for the yellow image, and the multicolour picture is transferred in known manner by means of gelatinized paper. Examples are also described in which three partial images are produced on separate films and united in superimposition, and in which printing-plates for three-colour printing are produced having the images identically situated on the plates.
