Title: Improvements in devices for discharging water of condensation from steam pipes
IPC: F16T1/22
Filed: 1927-10-18
Abstract: 279,450. Walter, P. Oct. 19, 1926, [Convention date]. Steam traps in which a float-operated pilot valve controls the main discharge valve have a casing 1 provided with an inlet 2 and outlet 3, and a main discharge valve 8 controlling the discharge passage 6. A drum 7 containing the valve 8 is formed with a strainer 7, and a baffle, 4 is arranged in front of the steam inlet 2. An air vent 17 is controlled by a loose valve 30 having passages for the flow of air. A float 12 is guided on a central hollow shaft 31 carrying the valve 8 and piston 10, and formed at the top with a seating for the pilot valve 14. This valve is lifted by an extension 13 of the float engaging a plate 13a. When the device is put into operation, steam is gradually admitted while air escapes through the valve 30, this valve being ultimately closed by the steam pressure, which also keeps the valves 8 and 14 closed. The rising of the float opens the pilot valve which allows steam to pass down the tube 31 to the space below the piston 10 to lift the main valve 8. A screw 21 controls a bye-pass for regulating the rate of closing of the valve 8. The main valve can also be opened by hand through a screw 19, or by a rotary eccentric. A plunger 18 is provided for depressing the valve 30 for testing purposes. Modifications are described in which the valve 14 is not coaxial with the valve 8, but is operated by the float through a lever. In the Specification as open to inspection under Sect. 91 (3) (a) the bye-pass controlled by the screw 21 contains also a non-return ball valve (Fig. 5 Cancelled and not shown). This subjectmatter does not appear.in the Specification as accepted.

Title: Turbine speed control
IPC: F01D17/06
Filed: 1964-07-06
Abstract: 1,078,531. Fluid regulation; pure fluid amplifiers. BOWLES ENGINEERING CORPORATION. July 6, 1964 [July 5, 1963], No. 27723/64. Heading G3H. A fluid control system for controlling the flow of air to actuate an air turbine 1 to maintain a constant speed comprises a fluid analogue amplifier 11 having a main jet 15 and control orifices 12, 13 supplied from a fluid source. The control signal at orifice 13 is controlled by a tuning fork 21, the fluid supply being connected to an annular outlet 19 whereby a negative pressure is developed across a leg of the fork during a portion of the cycle so that the supply both drives and damps the vibration of the fork. The signal at orifice 12 is controlled by a toothed wheel 4, driven at engine speed, which controls a supply of fluid from a source 7 whereby flow from the outlet 8 is restricted or not by the application or absence of the source 7 to the outlet 8. The frequency of the pulses at 12, 13 produce a predetermined difference at the required engine speed and the outputs at 22, 23 are at half the frequency difference. These signals pass to a full-wave rectifier 24 having an output 28 which is the higher pressure of the inputs 26 and 27. The signal 28 passes through a capacitor 30 and low pass filter 29 which comprises two tapered passages 31, 32 connected by passages 33 which are sufficiently narrow to serve as fluid inertances as well as resistances. The filter is tuned to a frequency, somewhat above the desired frequency difference and damps out high frequency signals. The frequency modulated signal appearing at the outlet 34 is fed to a frequency discriminator 36 by branch lines 39, 41. The pressure signal 39 acts on the flow from a supply 42 through a line 43 to a capacitor 44 which form a resonant circuit, the output at 51 being dependent on the pressure at 39 which deflects the flow. The output 51 leads to a control orifice 52 of an amplifier 53 in opposition to an orifice 54 supplied from the source. The outputs 57, 58 lead to a rectifier 61 which has the higher pressure as an outlet and this is connected through a capacitor 63 to a control nozzle 64 of an amplifier 68 whose other control nozzle 66 is connected to the second output 38 of the discriminator. The outputs 69, 71 provide a feedback through capacitors 73, 77 and also lead twin unit 84 which comprises output channels (86), (87) Fig. 3 (not shown) on either side of a dump (102) and control channels (82), (83) connected to the outputs 69, 71. The unit 84 is designed so that its output is equal to the square of the input and the outputs (86), (87) are relatively small compared with the channel (102). The curve shown represents the distribution of the stream and the exponential part of the curve are used for the outputs (86), (87). The outputs are connected to opposite sides of a piston 92 which adjusts the valve 2 controlling the air supply to the turbine.

Title: Improvements in or relating to reflex or twin lens photographic cameras
IPC: G03B13/20
Filed: 1938-09-23
Abstract: 517,495. Photographic cameras with rangefinders. KODAK, Ltd. Sept. 23, 1938, Nos. 27744, and 27745. Convention dates, Sept. 23, 1937, and Jan. 11, 1938. [Class 98 (i)] Reflex or twin-lens cameras providing finder images of substantially the same size as the picture to be taken are provided with a rangefinder including a beam accepting means spaced from the axis of the finder objective and producing a range-finding image in the viewing element of the view finder. Fig. 2 shows a twinlens camera having a range finder comprising porro prisms which direct the beams from lenses 22, 23 on to inclined mirrors 20, 21, so producing a split range-finding image substantially in the plane of that formed by the finder lens 16. For coupling the range finder to the focussing mechanism the mount of the lens 22 has a laterally-projecting arm 25 bearing on a cam 26. carried by the support 27 of the finder lens 16, which also has a projection 31 bearing on a cam 32 on the periphery of the mount of the objective 11. Movement of the focussing lever 13 rotates the cam 32 and so moves the finder lens 16 vertically, thus providing a parallax adjustment of the view-finder image, as described in Specification 517,494, and at the same time causing the cam 26 to move the range-finder lens 22 laterally in accordance with the distance for which the objective is focussed. A similar finder may be employed on a reflex camera. Fig. 3 illustrates a modified range finder applied to a reflex camera, in which a lens 40, porro prism 38, and mirror 39 form a range-finding image in that part of the field of the finder image which is interrupted by the mirror 39. The lens 40 is moved laterally by means of a rack engaging a worm on the spindle operating the rack-and-pinion focussing means, the objective being correctly focussed when the images from the lens 40 and the objective 33 combine to form a non-multilated complete image on the view finder. The twin-lens camera shown in Fig. 6 is also provided with a mulltilated image range finder comprising a prism 50 and lens 51 of the same focal length as the view-finder lens 16, which project into the finder field through a clear portion 48 of the finder mirror 15 an image received by way of a window 49 in the front of the camera. The finder lens 16 is given a vertical parallax-correcting movement in accordance with the focussing of the objective 11, as described in connection with Fig. 2, the consequent shifting of the view-finder image in relation to the fixed part of the image produced by the lens 51 producing, when the objective is correctly focussed, a non-mutilated complete image.

Title: Improvements in and relating to systems of electric motor control
IPC: H02P5/00
Filed: 1950-11-14
Abstract: 698,267. Control of several motors. BRITISH HOMSON-HOUSTON CO., Ltd., and WALLIS, A. S. Nov. 14, 1951 [Nov. 14, 1950], No. 27817/50. Class 38 (iii) Relates to a rolling mill drive in which the effects of inertia torque required for the change in kinetic energy of the motor and the load coupled to it are compensated in such a manner as not to disturb the speed which is obtained under steady working conditions, that is, such inertia torque is developed in a predetermined period. Mill motors M1, M2, are connected in series with auxiliary generators AG1, AG2, across the main supply generator G having means to vary its output at a controlled rate. The motor field windings M1a, M2a, are supplied from exciter CVE through rheostats 1R1, 2R1, by adjustment of which the motors are caused to operate at the required relative speeds. Each auxiliary generator has its main field winding Fl, F2, supplied from exciter RE1, RE2, the primary control field windings Al, A2, of which are each connected in series with condensers C1, C2, across rheostats 1R2, 2R2, which are in parallel with the armatures of the motors. Negative feed-back is provided by resistors Sl connected across the armatures of the auxiliary generators and supplying field windings B1, B2, of the exciters RE1, RE2. When the field excitation of the motor 1 is reduced by adjustment of rheostat 1R1 so increasing the motor speed, the coupled rheostat 1R2 automatically adjusts the voltage applied to the condenser circuit to a higher fraction of the motor voltage. The current in the control winding A1 is substantially proportional to the rate of change of motor voltage so that the correct compensating voltage is developed by the auxiliary generator during speed changes. The motors may be supplied from separate generators having common control means which, for each motor, is individually modified in accordance with the inertia torque of that motor and the coupled load, Fig. 2 (not shown). The condensers C1, C2, may be replaced by transformers, Fig. 3 (not shown). Specification 568,668 is referred to.

The moistening-device may be that described in Specification 440,334, [Group XVI], comprising a bar 22 pressing the sheets against the pad 27 which is supplied from a tank 29.  Each section 31 is connected by a rod 37 to a bell-crank 36 connected by a rod 35 to a lever 33, all the levers being mounted on a common shaft 34 and resembling the key-levers of a typewriter. Each lever 33 is retained in the depressed position by a catch lever 41 notched to engage a rod 11 and releasable by pressing a key 46 carried thereby.  By rotating an eccentric 47, all the levers 33 may be maintained in their depressed positions.  To maintain the bar 22 parallel with the pad, levers 24 carrying the bar are coupled together by a rod 49, and to prevent bending of the bar 22, springs 52 are provided between the rod 49 and shoes resting on p  the bar. In a modification, the sections rest on top of the tank and are slid into and out of position by hand.  Also each alternate section may overlap the adjacent sections to prevent liquid passing between the sections not withdrawn.
