Title: Electrical regulators
IPC: G05F1/567
Filed: 1971-04-19
Abstract: 1325257 Transistor amplifiers NATIONAL SEMICONDUCTOR CORP 19 April 1971 [23 March 1970] 24855/71 Heading H3T [Also in Division G3] An operational amplifier 12 forming part of a floating voltage or current regulator (see Division G3) comprises a differential amplifier stage 50, an optional differential amplifier stage 52 and an emitter follower stage 54. The base of transistor Q5 forms the non inverting input of the whole amplifier and is connected to a terminal 3 at which is produced a constant voltage, adjustable by a resistor 15, through the action of a temperature-compensated voltage reference source 11. The amplifier 12 operates as a voltage follower to maintain the voltage at an output terminal 2 at the value at the terminal 3, members 11, 12 being connected to an unregulated input voltage at a terminal 1. The base of a transistor Q6 forms the inverting input of the amplifier, which also includes current sources 60, 62, 64. In an adjusting operation produced by increasing the value of the resistor 15, transistors Q5 and Q7 turn off causing transistor Q8 to turn on and produce a current through resistors 56, 58 the resultant differential voltage produced at the bases of transistors Q9, Q10 tending to turn off transistor Q10. This causes an increase of current from the source 64 to the base of transistor Q11, thus turning the emitter follower 54 harder on to increase the voltage at the terminal 2. This increase is terminated when feedback to the transistor Q6 increases the potential of its base to that at the base of transistor Q5. The amplifier is of monolithic integrated circuit form and can be used over a wide high-to-low voltage range, so long as the difference between the voltages at terminals 1, 2 does not exceed the breakdown voltage of the integrated circuit transistors.

Title: Improvements in flushing cisterns for water closets
IPC: E03D1/18
Filed: 1923-10-09
Abstract: 218,535. Korgaard, C. C., and Larsen, C. F. E. Oct. 9, 1923. Siphon - discharge and combined valve and siphon discharge, waterwaste preventers; cisterns for.-The crown of the siphon is a narrow horizontal slit c in the wall of the cistern. When the chain p is pulled the inlet valve k is opened and a hinged flap e is turned up to close the inlet to a siphon d formed in the side of the cistern. When the water reaches the top of the siphon the weight n passes over the dead centre, closes the valve k and allows the flap e to open. The cistern is then discharged. If it is to be normally full the weight n is shifted towards the pivot and the supply is cut off by the action of a float m. The discharge is then started by the depression of the float m. In a modified construction the siphon is started by means of a valve in the long leg connected by a chain to the lever l. Discharge may also be started by tipping the cistern by means of a pull-chain or automatically and periodically by means of a continuous supply.

Title: Improvements in or relating to exchangeable show cases for show windows
IPC: A47F3/08
Filed: 1950-10-16
Abstract: 682,901. Displaying. BREITFEL, M. Oct. 16, 1950 (Oct., 21, 1949; June .16, 1950]; No. 25148/50. Class 3 (i) A plurality of show cases 4 are arranged for stepwise movement in a continuous circuit past a show window 3 via a plurality of track sections 8-12 extending horizontally and vertically, the track sections being of lengths which are multiples of the horizontal or vertical measurements of the show cases and the track being so proportioned that the show cases, which are arranged immediately adjacent each other, occupy the entire track except for one or two. free spaces. The show cases 4 are arranged to circulate in a clockwise direction, each show case being stopped for a predetermined period adjacent the window 3. The tracks 8, 10, 12 are arranged horizontally and the tracks 9, 11 are arranged vertically, the show cases being moved 'by six chain conveyors which are each driven by a separate motor, the motors being controlled to operate in sequence by a timing device 33. The conveyers have projections 22 which engage the rear or underside of the show cases. When the show cases are at rest, the section of the track immediately above the show case adjacent the windows is vacant to take this show case when it is moved. The show cases are then each moved round the track sections until this space is again vacant. This construction requires a space adjacent the window 3 which is two show eases high and two show cases deep; in a modification, the space adjacent the window is reduced to that required by one show case by leaving the space required by two show cases vacant in the track sections. In this case when the show case adjacent the window is to be changed it is moved one space downwards and one space to the rear. The next show case is moved two places upwardly to occupy the space adjacent the window and then all the show cases except the one adjacent the window are moved clockwise one space to leave the original two spaces vacant. This movement involves one of the conveyers moving first in one direction and later in the opposite direction and it is provided with two sets of flaps to engage the cases in opposite directions, both sets being hinged so that they fold out of the way when not required. The show cases may be arranged in two superposed horizontal rows, in which case they may, have an open top in addition to an open front.

Title: Method of producing nitroso compounds or oximes
IPC: C07D201/10
Filed: 1960-07-19
Abstract: A method of producing a nitroso compound or an oxime comprises reacting a nitrosation agent with an alkane or cycloalkane containing 5-10 carbon atoms while irradiating with actinic light where sulphuric acid of above 4% W/W concentration is caused to flow over the surface of the reactor through which the light passes and with which the reaction mixture makes contact.  In a preferred embodiment the reaction is carried out continuously in apparatus shown in section in the Figure <PICT:0903680/IV (b)/1> in which the hydrocarbon enters the reaction zone 7 through 16 and the nitrosation agent e.g. a mixture of NOCl and HCl or a mixture of NO and Cl2, through 5.  Sulphuric acid, preferably of at least 90% concentration flows over the reactor surface 4 from a reservoir 15 and a sulphuric acid solution of the product collects at 11 and is withdrawn at 12. The source of actinic light 1 and the reactor are surrounded by cooling jackets.  The flow of sulphuric acid is said to allow the reaction to proceed continuously without the transmission of active light being impeded by adherence of products and by-products to the reactor wall.  Examples describe the preparation of cyclohexanone oxime and dipropyl ketoxime.  e -Caprolactam may be obtained by heating a sulphuric acid solution of cyclohexanone oxime obtained by this process to effect Beckmann rearrangement.

Title: Improvements in devices for the remote control of water power machines
IPC: F03B15/10
Filed: 1926-10-12
Abstract: 285,111. Svala, C. E. Oct. 12, 1926. Transmitting-mechanism. - Hydraulic motors with a fluid relay regulating apparatus comprising a pilot valve and servomotor are provided with a separate continuously running motor which drives a pump supplying pressure liquid to the pilot valve and are electrically controlled from a distance by means of an electric motor which adjusts an arm in the linkage moving the pilot valve; one pump and motor may serve a number of machines; the motor may be a steam or hydraulic turbine, an internal-combustion engine, or an electric motor. A turbine T is controlled by a governor P or by a remotely controlled electric motor M1 which act on the linkage of a pilot valve F; the pilot valve F operates in its turn a control valve V which supplies the servomotor whereby the admission of water to the turbine is regulated. The pilot valve F is supplied by a separate continuously running motor A, and pump Z. The servomotor and its control valve V are usually supplied by another pump driven by the main turbine, but should this fail, are supplied, at a lower rate, from the pump Z and pilot valve F. In the arrangement shown in Fig. 2, the governor P or distantly controlled motor M1 move a pilot valve stem S controlling the pressures on opposite sides of a piston K which moves a valve V rigid therewith to control the passage of fluid from the second pump to the servomotor; if this supply fails a check valve U closes and the separately driven pump alone supplies the servomotor by way of the passage O and ports X. The main pump may deliver to a pressure chamber from which a pipe leads to the main control valve V; a valve -situated on this pipe is closed, for instance, by an auxiliary servomotor, when the turbine is stopped, so that a supply of fluid under pressure is preserved. The remote control permits of adjustment of the turbine speed in addition to the starting and stopping of the turbine.

Abstract: 932,457. Twin-sensitive devices employing vibrating masses. MINISTER OF AVIATION. Oct. 23, 1961 [July 21, 1960], No. 25435/60. Class 97 (3). A twin-sensitive device has two oscillatory bodies A, B, Fig. 2, on a torsion bar T1 mounted on a support frame F which is itself mounted to form an oscillatory body with another body C on torsion bar T2 at right-angles to bar T1, the . natural frequency of oscillation of bodies A, B about the axis Z of bar T1 and composite body ABFT1 and body C about the axis Y of bar T2 being equal to one another. The arrangement is such that if one pair of bodies is oscillating about its respective axis deflection of the whole device about axis of sensitivity X at right-angles to axes YZ causes oscillation of the other pair of bodies about its particular axis. The fixed framework MF is secured, or joins, bar T2 at points which are effectively nodal points in its length when bodies FABT1 and C are in anti-phase oscillation. Similarly, the points at which bar T1 joins or is secured to the frame F corresponds to nodal points in its length when the bodies A and B are in antiphase oscillation. In a modification the body C is in the form of an open frame surrounding the composite body FABT1 and joining a twosection torsion bar T2 which is supported on a main frame at two nodal points in its length at opposite sides of body FABT1. In a further form, Fig. 4, the bodies ABFT1 are on opposite sides of a main frame MF and the frame F is in the form of a two tine fork, the bodies A, B being at right-angles to bar T1 and such that bar T2 bisects the angle between them. The axis of sensitivity in this embodiment coincides with axis Y. The various members may be machined from a single piece of material.
