Title: Improvements in photographic photo-electric exposure meters
IPC: G01J1/42
Filed: 1938-10-11
Abstract: 520,037. Photo-electric exposure meters. METRAWATT AKT.-GES. FABRIK ELEKTRISCHER MESSGERATE. Oct. 11, 1938, No. 29426. Convention date, Oct. 11, 1937. [Class 40 (iii)] In a photographic exposure meter having a hinged cover with a light-reflecting coating disposed in front of the photo-element, the meter has at least two measurement ranges brought into operation by moving the cover into one or other of two definite positions exposing different light inlet apertures. As shown, the cover f hinged at p carries a coating g which reflects light admitted through a slot h on to the photo-element a connected to a direct current meter. On rotating the cover the slot h is enlarged to give a different measurement range the position of the cover being fixed by notches. Extraneous light is prevented from reaching the cell by foldable side members connected to the cover. The slot h may be of rectangular, curved or sinusoidal shape. The wall o of the light passage may be reflecting, and a transparent protecting screen may be inserted in the passage. Specification 454,704, [Group XX] is referred to.

Title: Improvements in or relating to the rolling of discs
IPC: B21H1/02
Filed: 1928-10-12
Abstract: 308,949. White, A. E., (Budd Wheel Co.). Oct. 12, 1928. Discs for automobile wheels are rolled to the required taper form between dies which preform, the blank by an upsetting co-operation. The billet shaped as shown in Fig. 1 to facilitate engagement by the combined rolling and forging dies 10, 11 is first upset as shown in Fig, 2, a centering boss 17 being formed during this operation. The bulging of the metal causes the scale to break off and fall away. The dies are further advanced to flatten out the upset portion still more and during or after this further motion the dies are rotated the advance being continued until the final form 4 is obtained. The plunger 13 is advanced during the final stage and in conjunction with the pin 15 rolls out the majority of the metal from the boss 17, that which remains being removed by cutting. The forging-apparatus may be distinct from the rolling.

Title: Improvements in or relating to the propulsion of ships by reciprocating plate propellers
IPC: B63H1/30
Filed: 1938-10-12
Abstract: 520,096. Reciprocating plate propellers. MARCON, R. E. Oct. 12, 1938, No. 29595. [Class 114] Reciprocating plate propellers of the kind in which adjustable abutments are provided for controlling the feathering of the plates to produce forward or backward travel of the ship are in this construction provided with an abutment which is acted upon by a bar slidable lengthwise in a guideway in the fin mounting to and from a position in which one or other of the limit stops is retracted to allow the blade to swing on its return stroke. The after end of the ship is provided with a compartment into which the fins or plates may be withdrawn and the compartment then sealed so that repairs on the plates may be effected. The reciprocating shafts 21, 22, 23, 24 are connected in pairs through rods 37 with two cranks 35 driven by gearing 34 from a suitable prime motor 33. The rods carry plate members 25, 26, 27, 28 which are pivoted on bolts 62 to bosses 61 upon the reciprocating rods. Within the rods are bars 72 having cam projection 70 with detent holes 71 in the outer face thereof. Inside the bosses 61 are two stop members 64, 65 which have tail members, 68 under spring restraint 67. As shown the spring holds the stop member 64 in the retracted position, whilst the cam 70 is used for forcing out the stop member 65 into its operative position. For reversing the motion of the ship, the rod 72 is slidden along to release stop 65 and force out stop 64. Control of the rods 72 is obtained from a central station inboard through rods 74, and screw and nut gear 75 on the crosshead 38. The upper crank 35 may be keyed to the central boss of the driving gear by a key 80 which is adapted to be slidden out of engagement with a corresponding slot in the central part of the crank gear. By this means, the upper pair of reciprocating rods may be put out of action. The rods pass through a compartment, 'into which the ends carrying the fins may be drawn after uncoupling from the drive. The closure members for this compartment may take the form of sliding bulkhead doors operated by gearing from a small engine.

Title: Improvements in or relating to control systems for induction motors
IPC: H02P25/26
Filed: 1951-12-18
Abstract: 698,594. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Dec. 18, 1951 [Dec. 18, 1950], No. 29606/51. Class 38 (iii) Relates to systems of the type described in Specifications 618,515 and 628,749 wherein one of the line connections to the motor is made through discharge means which are regulated to obtain different unbalanced conditions of stator voltage. In order to control the speed of the motor when its torque is below that provided by single-phase energisation, that terminal of the motor having the discharge means in series therewith is connected to one of the other stator terminals through an impedance which is rendered effective upon non-conduction of the discharge means to vary further the condition of unbalance. The impedance may consist of a resistor, Fig. 1 (not shown), or an autotransformer 81 may be connected between two of the motor supply-lines and have an extension 81a connected through resistor 82 to the motor. The purpose of this resistor is to prevent short-circuiting of the winding 81a when either of the valves 12, 13 is conducting. In another arrangement, the winding of an electromagnetic switch 83 is connected across the valve 13 so that the switch closes only when the valve is passing a low current to connect resistor 84 between two of the primary terminals of the motor. In this manner the impedance is brought into circuit only when it is needed, that is when the motor approaches singlephase operation. The response of the switch 83 is sufficiently delayed to prevent operation unless the valves are substantially non-conductive for several cycles of the supply frequency.
