The main frame is formed of longitudinal bars 2 spaced apart by braces 3, 4, and attached to a back bar 1 that carries the swivelling wheels 7. An axle 6 extending through bearing blocks 5 has mounted thereon the wheel 8, and at each end carries rotatable blocks 9 integral with bearings 11 for bent rods 10. The rods 10 carry heads for swath-turning. These heads are driven from the axle 6 through bevel gear 15, 16, 19, 18, actuating a loose sleeve 17 mounted on the lower part of a rod 10 and provided at its upper end with a gear 20 meshing with a bevel gear on the corresponding head. A hand-lever 22 attached to an extension of the block 9 can be fixed in any of three positions, to hold the gears 15, 16 out of mesh or to give a drive in either of two directions of rotation to the head. Another lever 26 connected by a link to the block 9 permits the head to be swung round the axle 6 to adjust the height of working. The heads may also be adjusted laterally of the machine by swivelling the rods 10 in their supports. Foot pedals may be installed in place of or additional to the hand-levers for adjustment. Stops may be provided on the hand-levers to limit the movement of the foot pedals in one direction.

Filed: 1971-05-11
Abstract: 1338486 Rotary positive-displacement pumps TRW Inc 11 May 1971 [5 Nov 1970] 14301/71 Heading F1F In an hydraulic double-acting sliding-vane type pump having a rotor 20 with vanes (not sHown) co-operating with a cam ring 22, pairs of outlet ports 67 in fixed plates 60, 160 communicate with an outlet bore 41 by way of an orifice 50 in an axially-movable spring-loaded valve-plate 40. The plate 60 comprises sections 61, 62 secured to each other, an annular land 76 separating a chamber B from an annular by-pass passage 79, a port 71 communicating with a space between a fixed shell 23 and the cam ring, and a passage 73 in register with a port 72 through which fluid enters said space from a reservoir (not shown) surrounding the shell. Pairs of inlet ports 68, 69 in said plates communicate with said space. When the pressure in the chamber B lifts the valve plate, the flow of fluid from the passage 79 to the port 71 creates suction at the port 72 to supplement the flow to the ports 68, 69. The valve plate is furnished with a pressure-relief valve 52, 53, 54, 56, 57 in register with an opening 58 in the shell. Pressures above and below the vanes are balanced by passages 67a, 69a in the plates 60, 160. An annular relief 78 to ensure sealing contact between the land 76 and the valve plate may be surrounded by an outer shield on said plate to minimize leakage therethrough when said plate lifts, Fig. 5 (not shown).

Patent GB-110193-A (GB)
Title: Improvements in Electrical Commutators.
IPC: B61L21/06
Filed: 1916-10-12
Abstract: 110,193. Sykes Interlocking Signal Co., W. R., and Tarrant, R. W. Oct. 12, 1916. Signalling-instruments.-In a rotary commutator, such as is used in railway block telegraph instruments, in conjunction with which a so-called bell-plunger is used to transmit signalling impulses, the actuation of the plunger is prevented at one of the positions of the commutator unless the latter has been brought to this position by movement in a predetermined direction. The invention is described as applied to a commutator having locking mechanism as described in Specification 110,192, the commutator 11 having a notched cam 18 engaged by a spring-pressed jumper 20, which is locked in its operative position by a sliding pin 28 connected to a bell-crank lever 25, the latter being moved to unlock the commutator by the depression of the bell-plunger 17. According to the present invention, a pawl 44, Fig. 3, pivoted eccentrically to the face of the cam 18 is so arranged that when the commutator is brought into the " train shunted " position by rotation in one direction, the pawl 44 falls by gravity into a notch 46, Fig. 4, in the stem 16 of the bell-plunger, thus preventing the depression of the plunger to send a signal. At the same time, the pawl 44 comes in the path of a pin 43 on the bell-crank lever 25, so as to prevent this from moving into the position in which the pin 28 locks the jumper to prevent rotation of the commutator. The commutator may therefore be turned freely past this position. If, however, the commutator is brought into this position by rotation in the'reverse direction, the pawl is kept by gravity out of the locking position, and the plunger can be depressed in the usual way. The notches 39, 40, 41, 42 in the cam 18 are shaped so that, from certain positions, the commutator can be moved in both directions, but from others in one direction only. The commutator has four operative positions in which strong or weak positive or negative current is connected to line on the depression of the plunger to operate the four-position indicator described in Specification 108,717, the indications given being " line blocked," " line clear," " train in section," and " train shunted." The invention ensures that the indication " train shunted " can only be given after the indication " line blocked," and allows the commutator to be turned in one direction through the " train shunted " position without the transmission of a bell signal. The depression of the plunger also gives the usual bell signals to which the visual indications act as a check. Transmitting ancl receiving indicators are provided at each station. the receiving indicator being connected in parallel with a relay controlling the bell.

Title: Electrical Rotational Speed Sensor
IPC: G01P3/488
Filed: 1969-03-19
Abstract: 1,188,486. Dynamo-electric machines. KELSEY-HAYES CO. 19 March, 1969 [8 Aug., 1968], No. 14552/69. Heading H2A. In a tachogenerator comprising a stator 20 and an L-shaped rotor 46 defining between them a working air gap 54 and a second gap 56, the gap 56 is filled with a low-reluctance fluid 57 e.g. oil or graphite with powdered iron in suspension. As shown, the stator comprises an L- shaped member 24, an annular ring 28 and a bearing ring 39 e.g. of P.T.F.E., defining an annular cavity 30 containing a permanent magnet 32 and sensing coil 34. Teeth 26, 48 are formed on the parts of member 24 and rotor 46 defining the gap 54 and the fluid is retained in gap 56 by seals 59, 61. The rotor is connected to a shaft 14 by a flexible drive ring 80 having outer fingers 86, which are engaged by fingers 72 on the rotor, and inner fingers 82, 84 which grip the shaft. The ring thus accommodates relative movement between the shaft and its housing 18 without altering the air gap 54 and gap 56.

[Class 47 (ii)] In a sprinkler system in which nozzles arranged in groups are opened by the closing of an electrical circuit by a thermostatic switch, the closure of the switch also releases a catch 38 which normally holds a weighted control lever 36 of a water cut-off valve 34 in its open position, but by an electromagnet E holds the lever in open position until the switch re-opens. The sprinkler nozzles are supplied with water from a supply-pipe 2 and also, if desired, with gas by a pipe 4 having a nozzle 14 sealed by a glass tube 16 which is broken upon release of water by the valve 34 by a wire loop 18 carried by a piston 17 and engaging under the tube 16. In one form, Fig. 9, a thermostatic switch is combined with a sprinkler nozzle. The switch comprises a glass tube 52 partly filled with mercury and provided with a restricted portion 54, and having contacts at each end connected to a filament C which explodes a cartridge 46 to blow out a plug 50. The plug is of glass or an easily-fusible alloy to ensure release of water if the cartridge fails to explode.

Title: Improvements in the production of alkaline earth metal pantothenates
Filed: 1941-11-13
Abstract: 553,317. Pantothenic acid. MERCK & CO., Inc. Nov. 13, 1941, No. 14617. Convention date, Feb. 26. [Class 2 (iii)] Pantothenic acid or a salt thereof is prepared by reacting an alkali metal or alkaline earth metal hydroxide or alcoholate, with #-alanine or an ester thereof and α-hydroxy-##-dimethyl- γ-butyrolactone under low temperature conditions in the presence of an aqueous medium, or a lower aliphatic alcoholic medium or an aqueous-lower aliphatic alcoholic medium. The preferred temperature is about 0‹C. The pantothenic acid may be obtained in either its dextro - rotatory, laevo - rotatory or racemic form and is preferably purified by extraction with ether and then with alcohol, adding acetone to the alcoholic solution and recovering the pantothenic acid from the latter solution. In examples (1) #-Alanine is added to a suspension of calcium oxide in water and cooled to 0‹C. when l-α-hydroxy-##-dimethyl-γ-butyrolactone is added. After four hours carbon dioxide is passed through until neutral and the product crystallized from methanol. (2) #- Alanine is reacted with α-hydroxy-##-dimethyl- γ-butyrolactone in caustic soda solution and the product purified by ether-alcohol-acetone treatment as above. (3) As in example (2) but using potassium hydroxide as solvent and neutralizing the reaction products with sulphuric acid. (4) As in example (2) but using a solution of sodium in iso-amyl alcohol as the solvent. The Specification as open to inspection under Sect. 91 includes also three examples in which #-alanine and α-hydroxy-##-dimethyl-γ- butyrolactone are reacted in the absence of a solvent. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to apparatus for testing the caliper of a paper web
IPC: G01B7/06
Filed: 1960-04-27
Abstract: 896,869. Feeding webs; delivering sheets. WARREN CO., S. D. April 27, 1960 [May 13, 1959], No. 14804/60. Class 100(1) [Also in Group XIX] Apparatus for detecting abrupt changes in caliper of a moving web of paper as it passes over a roll comprises a pivotally mounted skid capable of bearing lightly against the web and at least the part thereof which engages the web being flexible, and a transducer mounted on the skid and responsive to flexing of the skid caused by an abrupt change in caliper of the web to produce an electrical signal indicative of the abrupt change. As shown the web 6 passes over a roller 4 above and parallel to which is mounted a beam 2. A series of brackets 10 is secured to the beam and on these brackets skids 14 are pivotally mounted. Each skid comprises two thick plates 16, 18 between which is sandwiched-one end of a rectangular metallic plate 22. The other end of the plate 22 is formed with a lip 40 to prevent longitudinal flexing of the plate and rests lightly on the web 6. A crystal-type gramophone pickup cartridge 46 is mounted by means of a bracket 56 on the plate 16. An L-shaped wire rod 68 is secured at one end in the hole in the cartridge normally occupied by the gramophone needle and at the other end carries a hexagon nut 76 in which is threaded a screw 78. The screw 78 is turned down into contact with the plate 22 at a point about half-way between its side edges. When a bump occurs in the web 6 it causes the plate 22 to flex momentarily about a line parallel to the front edges 42 of the plates 16, 18 which in turn causes distortion of the crystal in the cartridge 46. This distortion is translated into an electrical signal which is transmitted through a band pass filter and amplifying devices to a magnetic recorder. Instead of being recorded the signal may be applied to work an alarm system or a warning light. The band pass filter passes only signals between 200 and 2000 cycles since signals generated by bumps in a web concentrated in that band.

Title: Apparatus for controlling the output position or the output  movement of the output member of a fluid-operated drive means
IPC: F15B9/14
Filed: 1970-03-26
Abstract: 1311524 Fluid-pressure servomotor systems FEINMECHANISCHE WERKE MAINZ GmbH 26 March 1970 [12 June 1969] 14908/70 Heading G3P Digital input signals are supplied to a control valve system 2 which supplies fluid to a motor 5 or piston until control surfaces 10 on a valve member 3 coupled to the motor cover control ports 6 in the valve housing and stop the motor. The next pulse supplies fluid through ports 7 which communicate through a passage 16 in the valve member 3 with the motor 5 while exhaust from the motor takes place through a passage 15 and further control ports in the housing. The pulses may be supplied by an electrical source 14 or they may be pneumatic, hydraulic or mechanical and have a frequency to provide a required speed of rotation of the motor 5. A linearly displaceable piston may be coupled to the valve by a rack and pinion or, as shown in Fig.4, the piston 20 may be formed with a linearly displaceable valve member 3 having control surfaces 10 to co-operate with control ports 35. Fig. 5 shows a further modification in which any one of a number of spring-loaded magnetic valves 22 .... 25 may be energized by a control signal, each valve providing a different extent of movement. This apparatus may be further modified by supplying the control ports in the valve housing through three valves in series, each valve having two positions so that the piston can be brought to any one of eight different positions. In Fig. 8, the valve 1 supplies fluid direct to the motor 5 so long as the valve is energized by a pulse from the source 14. When the pulse ceases, the valve moves to the right so that the supply continues through the valve member 3 until interrupted by the control surfaces. The ultimate position of the motor thus depends upon the duration of the pulse but is always a multiple of the increment of rotation determined by the valve member 3. Reference has been directed by the Comptroller to Specifications 1164866 and 1164867.
