Title: Improvements relating to gas-steam turbines
IPC: F02C3/30
Filed: 1930-01-02
Abstract: 347,728. Gas turbines. LEICH, C. F., 53, Quickbornstrasse, Hamburg, Germany. Jan. 2, 1930, No. 196. [Class 110 (iii).] A gas turbine is arranged so that the combustion chambers may be fed either with gas-steam mixture and air, in which case ignition is effected by a sparking-plug, or with steam and air into which fuel is injected through an atomizer, no sparking-plug being then required. The Figure shows two combustion chambers 7 arranged symmetrically but serving different turbines. Admission of gas-steam mixture and air, or of steam and air through ports 2, 5, is controlled by a cam-operated poppet valve 4. When the chambers are fed with mixture a sparking-plug is provided at 17. When, however, it is desired to inject fuel into the chambers the sparking-plug is replaced by an atomizer 12. The products of combustion pass through a mechanically operated discharge valve into a chamber 24 where they are cooled by the injection of water or steam. From this chamber they pass to the turbine.

Title: Remote controlled disengaging scotch-block
IPC: B61H7/02
Filed: 1931-01-02
Abstract: 370,434. Scotch blocks. GES. FUR OBERBAUFORSCHUNG UND RANGIERTECHNIK, EUROPHAUS AM ANHALTER BAHNHOF, Berlin.-(Assignees of Dietrich, J.; 17, Breitbrunnerstrasse, Munich, Germany.) Jan. 2, 1931, No. 250. Convention date, Jan. 3, 1930. [Class 103 (i).] A disengaging scotch block comprises a wedge b bearing against a vehicle wheel and carried 'by a link z pivotally mounted on a base a which remains on the rail when the wedge moves laterally out of locking ,engagement. The rope h connectedto the lock e is pulled to disengage the scotch block. The friction of the sliding piece c on the side rail d, after it is free from the lock e brings about the lateral movement of the wedge by means of the link f as the whole scotch block is carried forward by the wheel to be braked. The conicity of the wheel assists the disengagement. The toothed bar g increases the grip of the piece c. The block b is replaced by drawing back the block by means of the rope h until a nose-piece i strikes a stop k which pushes the sliding piece c forward. The rope h is wound up by a spring drum or an electric winch. Brackets y of the base a slide on the guide rail d. In the modification shown in Fig. 2 the side rail is dispensed with and the scotch block is held in equilibrium by counterweights on the lug l. The wedge p is deflected by the turning of a spiral body q bearing against the rail head. The body q is keyed on the axis of a double rope pulley p round which a rope o is wound and also a resetting rope s. To disengage the block the rope o is pulled and the body q is turned as the scotch block is carried forward by the vehicle wheel. The wedge b is carried by a lever z which rotates about a pin which also acts as a rope guide. When the pull on the rope o is released a spiral spring rotates the body q back to braking position in which a catch m engages a projection n on the base a to keep the block in readiness for braking. The body q may be roughened or have teeth where it engages the rail. A guide rail may be provided for this modification.

Filed: 1972-01-04
Abstract: 1336103 Protecting ships B KIRKSAETER and O RASMUSSEN 4 Jan 1972 [1 Feb 1971] 278/72 Heading B7S A ship's hull is, prior to launching, painted, provided with anti-fouling, and coated with paraffin wax. After launching, the wax layer provides protection against corrosion and fouling during fitting out and then wears away when the ship is put into general service to expose undamaged paint and anti-fouling. The need to redock the ship for painting is thus avoided.
Patent GB-801583-A (GB)
Title: Improvements in or relating to latch mechanisms
IPC: E05B65/32
Filed: 1957-01-04
Abstract: 801,583. Latches. FORD MOTOR CO., Ltd. Jan. 4, 1957 [Jan. 10, 1956], No. 446/57. Class 44 Relates to a door latch mechanism of the type having a rotatable bolt 16 and a rotatable ratchet 18 controlled by means of a pivotally mounted pawl 19, the latter being engaged by a suitable actuating member to release the bolt from an associated keeper. According to the invention, a manually operable release lever 31 is pivotally mounted to engage the pawl to swing the latter out of engagement with the ratchet 18 upon actuation of the lever, a pivoted locking lever 34 has a blocking portion 38 engageable in one position of the locking lever 34 with the released lever 31 to prevent actuation of the released lever in a direction to release the pawl 19 from the ratchet, a manually operable control lever 47 and an intermediate lever 53 are pivotally and coaxially mounted so that the intermediate lever has a first portion 54 engageable with the pawl 19 and a second portion 52 in abutting relationship with a part 49 of the manually operable control lever 47 to be rotated thereby in a direction to release the pawl from the ratchet, and means are provided for rotating the locking lever 34 between blocking and unblocking positions of the locking lever with respect to the manually operable release lever 31. As shown, the lock mechanism is mounted on an L-shaped plate 11 having flanges 12 and 13 substantially at right angles to each other. The pawl 19, mounted on the flange 12 is in the form of a bell-crank lever, one arm 22 of which is adapted to engage a rubber bumper 27 and to be engaged by a flange 33 formed on the release lever 31, when the latter is moved in an anti-clockwise direction by an exterior pushbutton (not shown), whereby to disengage the pawl from the ratchet. The locking lever 34 is operable by an interior locking rod 41 and by an exterior lock cylinder having a crank arm 42 engageable within a slot 43 of the locking lever. The central lever 47 which is operable against a spring 57, by an interior door handle (not shown) through a rod 44 is effective to release the pawl 19 through the portions 52 and 54 of the lever 53, the portion 52 then engaging a stud 61 on the locking lever 34 to move the latter to an unlocked position simultaneously with the unlatching of the door. The locking lever 34 is also moved to the unlocking position, should it be locked, by the closing of the door. When the lock is applied to a rear door, Fig. 5, the stud 61 is located in an alternative position shown, whereby operation of the interior door handle when the locking lever 34 is in locking position, is prevented. This arrangement also prevents automatic unlocking of the locking lever when the door is closed, since the portion 52 passes freely over the locking lever 34 when the lever 53 and the pawl are actuated by the rotation of the bolt.

Abstract: 1,180,900. Loading and unloading bale trailers. SPERRY RAND CORP. 3 Jan., 1969 [20 May, 1968], No. 522/69. Headings B8C and B8E. A bale collecting trailer has means to stack the bales as they are collected, means including a stepwise movable apron floor to fill the load platform with stacks of bales and means for discharging the stacks so that the bales can be fed one at a time to a barn. Bales are fed by a pick-up conveyer 12 to a stacking unit 9 which by means of an hydraulic lift platform 16, pivotal support gates 17, 18 and an hydraulically operated pusher 19 forms a stack which is fused on to an endless conveyer running over the bed 10 of the trailer. Stacks will be formed successively until a row is formed which contacts a trip 23 which causes the conveyer to run a step until a space is provided to receive a further row of stacks. When the trailer is full the first row of stacks will have reached a transverse conveyer 30 so that at the unloading point its operation causes the stacks to fall one at a time on to a discharge conveyer 34. The speeds of the conveyers 30, 34 are such that the latter conveys the bales singly and successively from the trailer.

Title: Improvements in and relating to electric motor control systems
IPC: H02P9/12
Filed: 1950-01-09
Abstract: 693,899. Exciting dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd., and PECK, P. E. Jan. 2, 1951 [Jan. 9, 1950], No. 624/50. Class 35. [Also in Group XXXVII] The armature 1 of a D.C. motor is supplied from generator 3 having a field winding 4 energized by exciter 5 which is in turn excited by a quick-response machine such as an amplidyne 7. A control winding 8 of the machine 7 is supplied through reversing means and is arranged to provide considerably more than the required nett steady-state excitation of the machine. When the motor is being accelerated a differential field winding 9 counteracts the excess flux of the winding 8 until a state of balance is reached. In order to reduce the forcing of the generator and consequently the acceleration, but not the speed, of the motor if the load exceeds a given value, an additional winding 10 is provided for the machine 7. This winding is connected across the compole and compensating windings 11 (shown separately) in series with a portion of potentiometer 17, which is shunted across exciter 5, and a portion of reference potentiometer 12, so that a voltage proportional to the amount of forcing applied to the winding 4 is added to a voltage proportional to the load current, the sum of these voltages being matched with a reference vo tage to provide the required control effect. For forward operation contact 15 is closed so that, when the voltage across winding 11 exceeds a predetermined amount, a current passes through rectifier 13 and winding 10 to reduce the output of exciter 7 and the acceleration of the motor. The overload trip operates before the motor current increases sufficiently to reduce the voltage of the generator 3. During retardation rectifier 13 prevents energization of winding 10, and for reverse operation contact 16 and rectifier 14 are rendered effective. The winding 11 may be replaced by a resistive or resistive-inductive shunt. Specifications 547,613, [ Group XXXVII], 619,848 and 621,782 are referred to.

Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To enable to observe the bottom of a contact hole or inside wiring. SOLUTION: In observing a contact hole 102, positive charges 106 are produced at the surface of an insulating material 101, and then, secondary electrons 104 are attracted from inside the hole in this electric field. In a wiring embedded in the insulating material, an electron beam is made to be intruded into a sample, and then, the existence of the wiring is reflected as a change in charging quantity at the surface, to be thus observed. Specifically, prior to the observation, the surface of the sample is irradiated for a predetermined period at an accelerating voltage which is different from an accelerating voltage at the time of the observation and actively produces positive or negative charges. Thereafter, the accelerating voltage is returned to a value suitable for the observation, and then, the observation is carried out.
