Title: Improvements in the low-temperature carbonisation of fuels and in apparatus therefor
IPC: C10B49/10
Filed: 1927-09-19
Abstract: 301,975. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 19, 1927. Coking processes. - In the low temperature carbonization of bituminous carbonaceous materials, hot gases or vapours which may be inert or may contain oxygen, are blown through the materials in such a manner as to keep the fuel in active movement on its bed but to avoid combustion or gasification to a higher extent than is necessary to produce the heat for carbonization, a temperature of 400‹ to 600‹ C. being employed. The fuel thus carbonized may be gasified also while in a state of agitation. Fuel from a hopper A is passed through a dryer B and cyclone separator C to a carbonizing chamber D, the hot gases being admitted through a grate R. The hot gases are circulated through a dust separator O, heat exchanger F and condenser G and back to the chamber D, a burner K being used to re-heat the gases. The hot coke overflows through a pipe which transfers it to a worm conveyer leading to a producer E. In Fig. 2, heated air is introduced through the grate G, fuel is charged from an inlet B and coke removed through an outlet F, fine coal collected in a separator D being returned bv a worm E to the fuel bed. Specification 214,544 is referred to in the first Provisional Specification.

Patent GB-288900-A (GB)
Title: Improvements in and connected with apparatus for delivering liquids in measured quantities by volume
IPC: B67D7/16
Filed: 1927-09-21
Abstract: 288,900. Smith, H. W., Smith, R. V., and Smith, I. C. V. Sept. 21, 1927. Fixedchamber apparatus.-Comprises means for compensating for small variations in the quantity of liquid delivered by a measuring chamber due to different rates of supply and discharge. For instance, the control cock of a measuring chamber is often closed automatically in constant times whereas the supply pump may work at various speeds resulting in slight variations in the total quantity delivered to the measuring chamber. Alongside the measuring chamber 1 is arranged a pipe 3 in communication with the chamber at the bottom below zero level 2-2 and in communication at the top with a small bore pipe 7. The chamber is filled by suction, and the supply pipe being of large diameter than the pipe 6, the liquid rises to a higher level in the chamber 1 than in the pipe 3. When the supply is shut off the levels in the pipe and chamber adjust, themselves to a common level. The capacity of the pipe 3 can be varied by introducing bodies 8 screwed on a rod 9 depending from the cap 4. By a suitable dimensioning of the pipes accurate compensation is effected. The device also acts to keep the quantity delivered constant when the discharge takes place under pressure. When the liquid is merely pumped into a chamber at or above, atmospheric pressure, the tube 3 is fitted with a pipe 7<a> to the atmosphere. Specification 234,857 is referred to.

[Class 142(ii)] A gripper shuttle 7, fixed to a flexible band 6 driven by wheels 2, 2<1>, takes the weft 3 from a feeding device 4, and draws it through the shed to a receiving device 8. A cutting device 9 cuts the weft before it is beaten up. The length of the band 6 must be shorter than the sum of the distance between the axles of the two wheels and the circumference of one wheel. The gripper shuttle comprises a pair of jaws 13, 13<1> mounted on a wedge-shaped member 14 carried by the band 6. The weft in the feeding device passes over a pin 16 and between pincers 17, 17<1> and is transferred to the shuttle when the latter slides along the feeding device as shown in Fig. 7. At the receiving side of the shed the jaws 13, 13<1> are opened by the receiving device and a pair of jaws on the receiving device grip and retain the weft.

Filed: 1960-07-20
Abstract: 883,454. Steering vehicles. HOUGH CO., FRANK G. July 20, 1960, No. 25269/60. Class 79(5). A motor vehicle power assisted steering system comprises a steering mechanism 12 having a drop arm 13 connected by links 11 and 19 to the steering arms of the wheels 10, the drop arm 13 being pivoted to a member 22 of a double acting piston and cylinder assembly 14, the piston rod 20 of which is pivoted to the vehicle frame 15 at 21. The piston rod 20 has a cross-section area about half that of the piston 34, One end of the cylinder is formed as a valve housing 31 comprising a valve spool 43 which is connected to the member 22. The spool 32 is biased to a middle position by springs 49 and 50. Fluid is taken from a reservoir 28 by a pump 26 and fed through the supply lines 24 and 37 into the rod side of the cylinder and through the passage 38 into the spool chamber. The spool has grooves 44 and 44a, lands 43 and 45 and a passage 46 connecting the grooves. The spool chamber connects with passages 40 and 41 leading to the cylinder and passage 42 returning to reservoir. In the mid-position, Fig. 2, fluid from the supply 24 passes through passage 38, groove 44 and passage 42 back to reservoir. Upon a steering movement in one direction, the spool 32 is moved to the right, Fig. 3. Now the passage 38 is closed by the land 43 and the passages 40 and 41 are opened to reservoir through the groove 44a, passage 46, groove 44 and passage 42. Pressure is maintained on the rod side of the piston which causes the assembly to contract and provide power assistance. When the steering movement is in the other direction, the spool 32 is moved to the left, Fig. 4, whereby the passage 42 is closed and fluid is supplied to both sides of the piston. Since the effective area of the one side of the piston is twice that on the rod side, the assembly is expanded providing power assistance at the same rate as is provided by the contracting operation.

Abstract: 795,294. Recording-apparatus. MUIRHEAD & CO., Ltd. Aug. 23, 1956, No. 25817/56. Class 106 (4). [Also in Group XL (b)] Apparatus for electrolytic recording of electrical signals comprises a transverse stationary electrode co-operating with a rotatable helical electrode having more than a complete turn and divided into a plurality of sections electrically insulated from one another, the helical electrode being rotated at a speed such that its whole length traverses the transverse electrode in the period of one scanning line and means being provided for electrically connecting the sections to a signal source in a predetermined sequence for predetermined periods of time. The helical electrode comprises two turns 13, 14 separated by an insulating part 15 and mounted on a drum 11 driven at twice the normal speed by gearing 17, 18, 19, 20, from a shaft 16 rotated at line scanning speed. The signal source S is connected to the fixed bar 23 and to the electrode turns 13, 14 in sequence by contacts 21, 22 operated by cams 21A, 22A on the shaft 16. Fig. 2 shows an arrangement in which the change-over between the turns 13, 14 takes place during the period of the scanning of the fastening strip at the transmitter. The helical electrode is cut away at the beginning of the turn 13 and at the end of the turn 14 by circumferential amounts indicated by A, B respectively. The helical electrode and the bar 23 are connected to the signal source by brushes 42, 43 engaging commutators 37, 38 driven at the speed of the shaft 12 carrying the drum 11 and provided with arcuate conducting strips 40, 41 extending over 180 degrees minus the angles 48, 49. The change-over from the turn 14 to the turn 13 takes place whilst both the brushes engage non-conducting portions of the commutators, whilst the change-over from the turn 13 to the turn 14 can take place at any point within the circumferential zone C, equal to the sum of the portions A and B, during which any overlap or simultaneous connection of the electrode turns will be nullified by the cut-away portions indicated by A and B. In a modification of Fig. 2, Fig. 3 (not shown), the helical electrode has three turns, the central turn comprising two half-turns separated by an insulating insert and the commutator connections are arranged to permit three turns of the helical electrode to be operative in sequence. The drum 11 carries ramps 36 shaped to engage the ends of the bar 23 whilst it is in engagement with the part c of the helical electrode. The two-turn helix is formed by two single-turn metal helices having the abutting ends held in close contact on the drum after having been coated with a thermosetting varnish which has been baked.
