Title: Improvements in or relating to liquid pressure motor cylinder devices, more particularly for operating soot blowers of boilers and the like
IPC: F28G15/00
Filed: 1940-02-16
Abstract: 538,881. Soot-blowers; hydraulic apparatus. AUTOMOTIVE PRODUCTS CO., Ltd., and BURROWS, H. L. Feb. 16, 1940, No. 2939. [Class 99 (ii)] [Also in Group XXIX] In an hydraulic motor, particularly for operating soot-blowers, in which alternate strokes of a double-acting reciprocating piston are used to produce uni-directional rotation through a ratchet device, the piston and cylinder unit is arranged so that the pressure liquid acts, during the return strokes, upon an effective area which is smaller than that acted upon during the alternate operative strokes. Fig. 2 shows the cylinder 34 in which operates a piston 37, 38 formed with rack teeth 25 engaging a pinion 22, which drives the blower nozzle or other apparatus through a ratchet device. The piston is bored to form an auxiliary working space 48, into which penetrates a tubular stem 46. For the operative strokes, liquid is admitted at 55 to the piston 37, while the liquid in the space 48 returns to the reservoir through the stem 46 and pipe line 54, the liquid in the annular space 73 also being returned past a valve 75. On the return strokes, liquid is admitted by the pipe line 54 to the space 48 and acts upon an effective area equal to the cross section of the stem 46, so that less liquid is required; and a quick return is obtained by causing the liquid in the space 40 to be byepassed to the space 73 through a connection 57, a valve 65 being held open for this purpose by a plunger 68 acted on by the liquid admitted at 54. The admission of liquid at 54 and 55 may be controlled as described in Specification 538,880.

Title: Improvements in and relating to Electric Motor Controllers.
Inventor: HIRST JOHN ARTHUR
IPC: H02P1/06
Filed: 1916-03-01
Abstract: 104,381. Hirst, J. A., and Brook, P. S. March 1, 1916. Controllers, actuating-mechanism for; interlock. ing-devices; with auxiliary switches.-The operating handle of a motor controller is so connected to the regulating-arm that it has a limited angular movement relative to the arm, and during that movement the handle moves axially to permit the operation of an auxiliary switch controlling the main circuit. The starter arm A carries a contact brush a<3> and has two jaws a<1>, a<2> mounted on the stud B. The yoke a<6> is between two horns on the handle part C, and cam-surfaces a', c<4> on the jaw a<1> and part C respectivelv are in contact in the zero position. The auxiliary switch D in the actuating-circuit of the main switch E, Fig. 3, is held open by the depression of the part d<1> by the handle. When the handle is moved towards the on ' position, the camsurfaces cause the part C to rise against the spring S and so permit the switch D to close. This completes the circuit of the coil e<3> which operates the main switch. The horn c<2> on the handle part C then engages the yoke a<6> and moves the arm A to cut out resistance. An auxiliary switch G, which is closed only when the starting-arm is in its initial position, is included in the circuit of the coil e<3>, so that the main switch can only be closed when all the resistance is in circuit, and a parallel maintaining-circuit is completed through the switch F. A mechanical interlock ensures that the axial movement of the handle can take place only when the arm A is in its initial position, and consists of an arm H with locking-jaws h<1>, h<2> which are held clear of the parts a<8>, c<5> of the arm and handle when the arm A is returned to zero to engage the pin h<3>. In a modification for an enclosed starter, sparking-contacts are provided on the arm and on the resistance contacts. The two circuit-breakers E, Fig. 10, are fitted with overload coils O, which, in the event of an excess current, open switches o<1> in the maintaining-circuit. An auxiliary switch K is closed in the ' full on ' position of the arm A to short-circuit the switch D. On the return movement of the handle, the circuitbreakers are not opened until the arm A is moved to open the switch K.

Title: Improvements in or relating to organs
IPC: G10B3/06
Filed: 1927-02-03
Abstract: 288,759. Bawtree, E., Feb. 3, 1927. Pipe organs; flue-pipes.-Swell effects are obtained by controlling flue-pipes by means of shutters varying the size of the windway continuously between limits. When a shutter in a pipe is operated, the wind pressure is simultaneously varied to maintain it constant at the windway either by a throttle valve or an escape valve; or in one construction (Fig 8, not shown) the shutters may be directly operated by the variable pressure in the wind chest. In Figs. 1-3, the shutter B and valve have rectilinear movements imparted from the balanced pedal E. The shutter B varies the width of the windway a by the inclined ends b<1> of its active edge. The shutters and valves may be arranged to rotate as indicated in Fig. 7. In this construction, pedal actuation is combined with double-touch. The double-touch contact of a key opens a valve f<4> admitting wind to a pneumatic F which expands against the action of a spring f<3>. The lever f, whatever its position due to actuation of pedal E, rocks about fulcrum f<x> and operates the links e<5>, b<3>, c<3> thus opening the shutter and valve and accentuating the note, any excess movement being taken up by springs or by the flexibility of the links b<3>, c<3> which contact with stops b<5>, c<5>.

Title: Closure removing apparatus and method
IPC: B67B7/18
Filed: 1974-01-24
Abstract: 1435882 Screw cap remover J F R OUELLETTE 24 Jan 1974 [26 Jan 1973] 03281/74 Heading B8T In apparatus for removing screw closures from containers, which are arranged in four rows each having six bottles in cases 16, four closure detectors 36 detect which containers in the four rows have closures and a column sensor 34 counts the columns as the cases 16 move along the conveyer 14. The information from the sensors 34, 36 is stored in a memory unit. A second column sensor 38 detects when the containers are in momentary alignment with twelve continuously rotating closure removal heads 40. The information in the memory unit is then used to lower any head 40 which may be over a container having a closure. As the heads 40 fit over any closures and unscrew them an orifice 128 in hollow shafts 86 of the heads enters a vacuum chamber 88 resulting in a sucking action between the closure and the head 40. Thus when unscrewing is completed and the heads are raised the closure remains in the head until the orifice 128 enters a pressure chamber 90. The closure is thus blown out and is directed by an air stream from orifices 161 to a collector 44. The speed of the entire operation is such that there is no interruption in the progress of the cases through the apparatus. The raising and lowering of the heads 40 is controlled by twelve solenoid air valves 100 and twelve air cylinders 96. The air valves receive their triggering impulses from an electronic control circuit, which incorporates the memory unit.

Title: Process for the production of middle-distillate hydrocarbon oils
Inventor: POTTER EDWARD BARRIE VERNON
IPC: C10L1/06
Filed: 1956-02-02
Abstract: Middle-distillate hydrocarbon oils boiling within the range 250-750 DEG  F. are produced by alkylating a straight-run naphtha with a catalytically cracked naphtha.  Thermal or catalytic alkylation, preferably the latter, may be employed, in batch or continuous processes.  Thermal alkylation may be carried out at 550-900 DEG  F. and 200-300 atmospheres.  Catalytic alkylation may be carried out at from ambient temperatures to 650 DEG  F. and sufficient pressure to maintain the reactants in the liquid phase. Catalysts include aluminium chloride, sulphuric and phosphoric acids, HF-treated alumina, HF-H2O-BF3, and alumina-boria.  The straight-run naphtha is preferably in excess, e.g. in a weight ratio to the catalytically-cracked <PICT:0791639/IV (b)/1> naphtha between 2:1 and 20:1, in order to minimise polymerization of the olefinic constituents of the feed stock.  The catalytically-cracked naphtha preferably boils below 430 DEG  F.  The process may be employed to increase the middle distillate yield in fractionating a crude oil, referring to the drawing, the crude is fed to the fractionating tower from which the following fractions are taken: (2) straight-run naphtha; (3) middle-distillate cut; (5) Diesel fuel cut; (6) catalytic cracking feedstock; (7) residuum.  The catalytic cracking feedstock is cracked and the product boiling up to 430 DEG  F. used to alkylate the straight-run naphtha from (2).  The product from the alkylation unit may be separately re-run, or re-cycled to the main fractionating tower by line 11.

Abstract: 435,680. Electromagmetic switches. ELECTRIC AUTO - LITE CO., Champlain Street, Toledo, Ohio, U.S.A. Feb. 2, 1935, No. 3477. Convention date, Feb. 2, 1934. [Class 38 (v)] An electromagnetic device such as an automatic cut-out or circuit breaker is compensated in operation for temperature changes by providing means for automatically varying the normal or unattracted position of the armature with respect to the core in response to temperature change, the armature being for this purpose supported by a hinge element formed of bimetallic or thermometal material. As shown in Figs. 1 and 3 the hinge member 42 supporting the armature 24 is made of bimetallic material, preferably resilient, the member 42 being riveted at one side to the armature and at the other to a bracket 40 attached to the U-shaped magnetic yoke 18 within which is arranged the operating winding 20 and fixed magnetic core. A coil spring 38 is arranged between a recess on the projecting end 34 of the armature and a projecting hook 39 of the bracket and deflection of the bimetallic hinge-member 42 with changes of temperature varies the tension of this spring acting on the armature and may thus be made to give uniform operating characteristics with varying temperature. The bracket 40 may be slotted at 41 so that by loosening the securing screw it may be adjusted with respect to the yoke to vary the tension of the spring. The retracted position of the free end of the armature is limited by a bent-arm stop 56 attached to the other limb of the yoke and the armature carries a contact 26 adapted to engage a fixed contact 28. The latter is carried by a U-shaped support 30 the limbs of which may be bent as at 33 to adjust the position of the contact.
