Filed: 1958-01-24
Abstract: 840,177. Photographic cameras, lens turrets. KODAK Ltd. Jan. 24, 1958 [Jan. 30, 1957], No. 2476/58. Classes 97(1) and 98(1) In a photographic camera a lens turret is indexed by members engaging axial grooves disposed about the axis of rotation of the turret at the same angular intervals as are the objectives mounted on the turret and axially spaced annular grooves join the ends of the axial grooves. Preferably, a sleeve 22 is freely mounted on a bar 16 fixed to the camera front 11 and is formed with axial grooves 26 and annular grooves 25 engaged by steel balls 34 carried in radial holes in the boss 36 of the turret and retained therein by ring 35. In one angular position of sleeve 22 and attached arm 18 any objective can be aligned with the exposure aperture 15 and moved inwards towards it so that finger 43 enters one of holes 44 provided in the turret and balls 34 are carried to the inner ends of groove 26. Thereafter sleeve 22 may be rotated by arm 18 so that balls 34 lock in the inner groove 25 and sleeve 22 is thrust away from the camera front to compress spring 27 against washer 29 fixed to bar 16. Adjustable locating studs 39 are thus pressed against steel inserts 37 by spring 27 to locate the aligned objective accurately on the camera. Shoulders 42 are provided on one insert 37 to prevent the turret from being rotated before it has been unlocked and withdrawn.

Title: X-ray apparatus
Inventor: DRENCK KAJ
IPC: H05G1/00
Filed: 1954-01-29
Abstract: 803,217. Supply systems for X-ray apparatus. DRENCK, C. [trading as DRENCK, C. [Firm of]]. Jan. 31, 1955 [Jan. 29, 1954], No. 2801/54. Class 38 (4). In a supply circuit for an X-ray tube N comprising a pair of high-tension transformers, the secondary windings L, M of which supply the tube in series and the primary windings E, F of which, whilst being connected in series with one another, are separately supplied from different variable tappings of a voltage dividing transformer C connected across the supply source A, B, and wherein one of the hightension transformers also has a winding, such as L1, for supplying filament current for the tube, the voltage dividing transformer is of annular form with the tappings H, K thereof movable independently of each other in different planes so as to be able to pass each other. The tube and two high-tension transformers may be mounted within a common cylindrical easing, forming a transportable unit which is connected by multicore flexible cable to a control box housing the voltage dividing transformer and other control gear, such as relays V, Vmax, switches O, I, ST and protective resistors S1, S2 for limiting input voltage to the high-tension transformers during non- conductive half-cycles of the tube. To effect an exposure, with the circuit shown, switch I is manually closed after the timer has been set to the desired exposure time, which closes switch ST, to complete an energizing circuit for relay V over contacts b, I, a, o, ST and normally closed contacts of relay Vmax. Relay V responds, holds in over a contact by-passing b, a and I, closes circuits for an indicator lamp L and the timing motor MT and connects the primary windings of the high-tension transformers for energization from the tappings H, K of the voltage dividing transformer C, the tappings being in the " minimum " position and a " shock-reducing " resistor D1 being included in the energization circuit. Movement of tapping H to the desired operating position changes over contact b to short out D 1 and opens contact a. Tapping K is then moved to the desired operating position. Energization of the tube continues until relay V is deenergized by the opening of the timer contacts ST, the contacts of the protective relay Vmax, or of the manually-operated switch 0.

Title: Improvements in or relating to liquid pressure control systems
IPC: B64C25/22
Filed: 1937-12-18
Abstract: 494,148. Hydraulic transmission of power; valves. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. Dec. 18, 1937, No. 2816. [Classes 69 (ii) and 135] [Also in Group XXXIII] A liquid pressure control system for the operation of controlled units on aircraft which are assisted in one direction of their movement by gravity or other external forces, comprising a pump or master unit operating a double-acting slave cylinder, and a valve or combination of valves limiting the rate of flow of liquid from one end of the slave cylinder as the controlled unit moves in the direction in which its movement is assisted, whilst allowing substantially unrestricted flow of liquid into the same end of the slave cylinder to move the controlled unit in the opposite direction is characterized by the provision of a byepass valve opened to byepass the flow-limiting valve in the event of an increase in the resistance to movement of the controlled unit, by the resulting rise.in pressure in the liquid flowing to the slave cylinder. A system for actuating the retractable undercarriage of an aircraft comprises, Fig. 1, a reservoir 14, an engine-driven pump 13, distributing valve 15 and double-acting jack 8 ; a valve mechanism 18 comprises a lightly loaded valve 21 allowing practically free flow to the lower end of the jack, and a heavily loaded valve 22 restricting flow from said end of the jack. The actual valve arrangement is shown in Fig. 2. A common casing 51 contains a ball valve 58 lightly loaded by a spring 62, and a ball valve 64 heavily loaded by a spring 66 whose compression is adjustable by means of a plunger 67 and screw-threaded sleeve 68, the plunger being positioned relatively to the sleeve 68 by a pin 71 capable of being passed through registering holes in the two parts ; the pin 71 provides a releasing device for the restrictor valve, removal of the pin taking off the loading from the spring 66 and so freeing the valve 64 ; this facilitates operation of the system by an auxiliary hand pump in the event of failure of the engine-driven pump. The byepass piston valve 73 is normally held in its inoperative position by a spring, and is moved axially to operative position by pressure from the pipe line 16, Fig. 1, through which liquid flows to the jack to move the undercarriage in the direction in which it is assisted by the external force. The invention is stated to be applicable to retractable undercarriages, fairing doors, bomb hoists and like apparatus on aircraft.

Title: Improvements in or relating to the speed control of multi-drive work units, particularly the stands of a tandem rolling mill
IPC: B21B37/46
Filed: 1943-02-22
Abstract: 563,866. Control of D.C. motors driving rolling mills. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 22, 1943, No. 2925. Convention date, Feb. 21, 1942. [Class 38 (iii)] [Also in Group XXII] A strip steel rolling mill has the stands driven at successively increasing and corelated speeds by motors 8, 10, 12, 14 supplied from a Ward- Leonard generator 2. When a new strip 101 is to be threaded through the stands, switch 44 is moved to the left to connect a tachometer generator 36 to a relay 46 which lifts and causes a pilot motor 26 to reduce the field. of the generator 2. When the motor 8 has reduced to a suitable speed for threading, relay 46 drops. As the strip 101 is threaded through the first stand the load on the motor 8 increases and relays 30, 71 lift to substitute tachometer 38 for 36, whereupon pilot motor 26 further reduces the field of the generator 2 until the motor 10 has reduced to a suitable speed for threading. Similar action occurs as the strip is threaded through the second and third stands. Upon completion of threading, switch 44 is returned to position shown, whereupon relay 48 lifts and pilot motor 26 increases the field of the generator 2 to accelerate the motors 8 &c. until the tachometer 36 energizes an opposing coil on the relay 48 sufficiently to cause the relay to drop.

Power meters; current meters with rectifiers. - Means for indicating at a distant point 4 the power and reactive power in a system 1, 2, 3 comprises a current transformer 7 arranged to produce a voltage proportional to the primary current, which voltage is rectified by two commutators 10, 11 driven by a synchronous motor 12 and having their brushes set at 90 electric degrees apart. The brushes 13, 13<1>, 14, 14<1> of the commutator 10 are so set that the rectified current supplied to the distant direct-current Instrument 5 is proportional to the power, as described in Specification 272,289. The brushes 15, 15<1>, 16, 16<1> of the commutator 11 are displaced 90 electrical degrees from the brushes of the commutator 10, and consequently give an indication on the distant direct-current instrument 6 proportional to wattless current or reactive power. The transformer 7 may have a gap in its magnetic circuit as described in the above-mentioned Specification, or may have a closed magnetic circuit and have a reactance 8 across its terminals. As each commutator rectifies two complete cycles for each revolution, the motor 12 is arranged to rotate through one revolution for two cycles, or the reduction is effected through gearing.
