Title: Improvements in or relating to photographic cameras
IPC: G03B13/20
Filed: 1932-01-07
Abstract: 379,954. Photographic cameras. LEITZ GES. E., Optical Works, Wetzlar, Germany. Jan. 7, 1932, No. 507. Convention date, Jan. 7, 1931. [Class 98 (i).] In a camera of the kind provided with a telemeter which is adjusted from the focusing mount of the camera lens through intermediate mechanism, the arrangement is adapted for use with camera lenses of different focal lengths by providing on the mount of each lens means whereby, when the mount is attached to the camera, the transmission ratio of the focusing movement of the lens mount to the movement of the telemeter is automatically adjusted to a value suited to the focal length of the lens. In the form shown in Fig. 1, a flange on the focusing lens mount B has external and interal screw threads B<2>, B<3> engaging respectively threads on a sleeve C secured at C<1> to a fixed part D of the camera, and threads on a tubular intermediate transmission member E, which is slidable axially in the sleeve C but is prevented from rotation therein by pin-and-slot connections F, F<1> with the fixed part D, and which carries at its inner end a cam El adapted to actuate the telemeter mechanism (not shown). The internal thread B<3> may have the same pitch whatever the focal length of the lens, but the pitch of the external thread B<2>, and the cooperating thread on the sleeve C which forms part of the mount, is so chosen in accordance with the focal length of the lens that the scaleratio of the focusing adjustment produced by rotating the mount B to the telemeter adjustment produced by the consequential movement of the cam E<1> is that necessary to ensure the accurate control of the focusing of the lens by observation of the telemeter. In a modification, the fixed sleeve C is internally threaded at both ends. One end engages an external thread on the lens mount B, as shown in Fig. 1 ; the other end engages an external thread on the tubular intermediate transmission member. A tubular extension of the mount B extends within the transmission member and is coupled thereto by pin-and-slot devices similar to F, F<1>, as shown in Fig. 1, so that in this modification the transmission member rotates with the mount during the focusing adjustment, and is slidable axially relatively to it, to actuate the telemeter. The pitches of the screw threads are determined as in the first example. Specification 371,252 is referred to.

Title: Device for the evaporation of a liquid in a current of air for therapeutic inhalations
IPC: A61M16/18
Filed: 1951-01-08
Abstract: 684,449. Respiratory appliances. PACHETTI, A. Jan. 8, 1951 [Jan. 31, 1950], No. 509/51. Class 81 (ii). In an inhalation appliance liquid to be evaporated is contained in a porous receptacle 9 mounted in an outer casing 1, through which a current of air is passed. Air, drawn through the outlet 18, enters the casing 1 through a non- return valve 8 and is directed over the surface of the porous container 9 by a baffle 7. The inner container may be filled after removal of a closure cap 15. When the appliance is in use the orifice 19 is closed with one finger and the desired amount of diluting air is determined by a rotatable cap 20 masking orifices 22. Removing the finger from orifice 19 opens the inhaling tube 18 to atmosphere and interrupts any further flow of inhalant.

Title: Apparatus for Indicating the Rotation of a Mechanism.
Inventor: LAMBERT EDWIN ALFRED
IPC: G01P3/26
Filed: 1918-01-12
Abstract: 122,036. Lambert, E. A., Gill, J. F., and Chaviara, J. N. Jan. 12, 1918. Revolution-direction indicators; fluid speed indicators.-Apparatus for indicating when a shaft, such as a ship's propeller shaft, is rotating, together with the direction and speed of rotation, is based on the known principal that the maximum pressure produced in an oil film separating a fixed and a rotating body exists at a point beyond the geometrical centre in the direction of rotation. To the shaft a, rotating in bearings in a box b, is secured a disk c against one face of which is pressed a plate d, shaped as shown in Fig. 5. Pressure is applied by a spring-depressed plunger f, Fig. 4, through a plate j, secured to the plate d. On either side of the centre cavities g are formed, communication between these and the surfaces in contact being effected by holes h in the plate d. Secured over the cavities between the plates j, d to form liquid-tight joints are flexible diaphragms i with which engage contact-pieces i carried by a lever k pivoted to flanges of the plate j. The rod f engages the plate j at a point equidistant from the centres of the pieces 1. Movement of the lever k is communicated to a spring-supported bell-crank lever m which operates an indicator by electric, hydraulic, or pneumatic means. In operation, the lever k remains at the central position when the shaft is stationary, and is tilted in different directions according to the direction of revolution of the shaft. The requisite oil film is produced by immersing the lower parts of the device in oil contained in the casing b. In a modification, the lever k may be dispensed with and the diaphragm movements resisted directly by springs, and pipes in communication with the cavities g may be connected to a differential pressure gauge; pistons may be employed instead of the diaphragms. When used as a speed indicator, the indicating device is calibrated in accordance with the fluid pressures produced at different speeds.

Title: Improvements in and relating to electric switches
Inventor: CLARKE WALTER WILSON HUGH
IPC: H01H35/14
Filed: 1962-01-09
Abstract: 998,261. Inertia switches. INERTIA SWITCH Ltd. Dec. 24, 1962 [Jan. 9, 1962], No. 854/62. Heading H2B. In an inertia switch, which is actuated by the axial deceleration of a device, e.g. an artillery shell, which is also subjected to a centrifugal force, a slug 12 in a cavity 11 of a body 2 is retained against one wall of the cavity by a magnet 9 until the decelerating force is applied to the switch, whereupon the slug 12 moves towards the other wall of the cavity and closes an electric circuit by completing the circuit between a conducting layer 6 and a conducting annulus 3. Due to the centrifugal force the slug is held against the side wall of the cavity, i.e. the annulus 3, about which it hinges when deceleration occurs to close the switch. The force exerted by the magnet 9 may be varied by altering the thickness of a spacer 8. In another embodiment, Fig. 2 (not shown), the slug is retained against one wall of the cavity by a spring.

Filed: 1929-01-10
Abstract: 325,945. Needham, J. H., and Andrewartha, H. C. Jan. 10, 1929. Charging and discharging batteries.-A switch for automatically connecting a battery for charging purposes to a supply, e.g. a rectifier in which the polarity of supply may vary, comprises an oscillating beam member, consisting of separate insulated metal bars for each conductor of different potential which are adapted to engage corresponding fixed contacts to control the battery circuit as the beam is moved under the action of a continuously-energized voltage coil so that the output current is maintained in the correct direction, the battery being automatically disconnected on failure of the supply voltage. As shown in the Figure the incoming leads J, J are connected to metal bars A, A1 separated by insulating members B, B the upper bar being pivoted on a knife-edge pivot E. The lower bar carries a downwardly depending soft iron bar C1 the end of which is normally midway between the poles NS of a fixed permanent magnet F. The bar C1 carries an energizing coil J<1> connected across the supply mains so that its lower end is polarized to swing in one or other direction in accordance with the polarity of the supply, the bars A, A<1> completing the battery circuit through fixed mercury cup contacts G, G' or G2, G3. The battery circuit also includes a series coil K on the bar C<1>, the action of which normally assists the voltage coil J1 in maintaining the switch in its displaced position. On failure of the supply, however, reversal of current in the series coil due to feeding-back of the battery causes a repulsion of the bar from the adjacent pole of the permanent magnet and a consequent disconnection of the battery from the supply. The mercury cups may, if desired, be replaced by solid contacts.

Patent GB-1383791-A (GB)
Title: Coded record
IPC: G06K7/016
Filed: 1972-01-07
Abstract: 1383791 Data record and reading system MONARCH MARKING SYSTEMS Inc 7 Jan 1972 [8 Jan 1971 (3)] 917/72 Heading G4M A data record such as a tag or a label has adjacent absorbing and reflective regions each of three possible widths the relative widths of all adjacent pairs determining a binary value, e.g. a wide section followed by a narrow section indicates a " 0 ", a narrow section followed by a wide section indicates a " 1 " and a 3 out of 6 code is used so that only three different widths are required. Signals from a hand held optical reader or a fixed optical reader are fed to an A/D converter and set a flip-flop 508 to indicate either a Black mark or a White mark. A Black signal sets a One shot 510 and enables AND gate 528 to feed clock signals to a counter 530. At the end of the Black mark a White signal is set, AND gate 528 is no longer enabled and clockpulses are fed to counter 534. When the widths of the first two marks have been measured by the counter the values are subtracted to produce a " 1 " if White is larger than Black and a " 0 " if Black is larger than White. This is fed to an exclusive OR gate 548 also receiving the Black signal to feed to a shift register the correct bit value. The trailing edges of the Black and White oneshot pulses reset their respective counters. Initially the reader is in a scan mode until a forward start or a backward stop signal is detected. The reader then switches to a read mode. The reader is arranged to ignore bits produced by comparing the width of spaces between characters with the last and first bits of preceding and succeeding characters. The reader can detect overflow if the count representing bar width is above a predetermined maximum, can count for a predetermined number of characters and can detect faulty codes that are not 3 out of 6 codes. Detection of a forward stop or a backward start returns the reader to a scan mode.
