Title: Improvements in or relating to the purification of cracked petroleum oils and similar cracked products
IPC: C10G31/06
Filed: 1930-07-21
Abstract: <PICT:0361396/III/1> Cracked distillates are purified from gum forming and resinous bodies by heating them under flow to a temperature sufficient to cause vaporization but under a pressure which maintains the liquid phase for such time that the resin and gum forming bodies are polymerized and passing the products still maintained in the liquid phase through a bed of absorbent material at rest.  The cracked distillate from a tank 1, mixed, if desired, with fixed cracking gases supplied through a pipe 18, is delivered by a pump 3 to a heating coil 6 where it is heated to 500-600 DEG F. under 600-1,000 lbs. per square inch pressure.  The oils still under pressure are led through a bed 10 of fuller's earth, &c. and are then vaporized by reduction of pressure in a fractionating tower 13.  The vapour passing off at the top of the tower being condensed in a cooler 16 and the condensate led to a storage tank 17.  The polymerized residue are led off through a pipe 14.

Patent GB-758787-A (GB)
Title: Radio beacon of complementary code type
IPC: G01S1/02
Filed: 1954-08-03
Abstract: 758,787. Radio navigation. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Aug. 3, 1954 [Aug. 10, 1953], No. 22489/54. Class 40 (7). A radio beacon which defines a course line as an equi-signal path formed by means of two overlapping polar diagrams keyed in complementary code such, for example, as A-N morse keying, is characterized by the subdivision of the signals into pulses so that each code element is composed of a plurality of pulses. It is preferably arranged that the change-over from one polar diagram to the other occurs in the periods between the pulses when there is no transmitted signal. This arrangement necessitates the synchronization of the pulse modulating and keying arrangements. Fig. 3 shows the signal received to one side of the course line where there is A-N keying and each dot comprises 3 pulses and each dash 9. The keying changes between one diagram and the other take place in the intervals marked 33 and the reverse changes in the intervals marked 34. In a simple embodiment aerial 10 fed over coupling 15 from transmitter 14 radiates omnidirectionally while loop aerial 11 radiating a figure-ofeight pattern is fed over keyer 17 reversing the feed. Keyer 17 is controlled by relay 18 coupled to the output of code transmitter 19 which supplies signals in the A-N or other chosen rhythm. A blocking valve 20 indicated as in the output stage of the transmitter is utilized to effect the pulse modulation and is controlled by relay 24 operated by pulse generator 25. This pulse generator feeds a pulse counter 36 which counts pulses in sets of three or nines in the correct order as required to operate keyer 19. A suitable relay chain pulse counter is described with reference to Fig. 4 (not shown).

Abstract: 376,527. Grab-buckets. DYGGVE, E. V. P., 50, H. C. Lumbyesgade, Copenhagen. Aug. 12, 1931, No. 22782. [Class 78 (iv).] The buckets are pivoted at 2 on a rigid frame 1, Fig. 1, or on the lower member 25 of a linked frame 25, 26, Fig. 8, and the bucket arms are connected by links 12 with the lower block 6 which is constrained to move in the vertical axis of the grab without the use of rigid guides on the frame. In one arrangement, toothed sectors 10 on the bucket arms 3, Fig. 2, mesh with interengaging gear wheels 15 which are mounted on spindles 14 in the block 6, and the links 12 which connect the arms 3 with the block are provided with interengaging sectors 11. As shown in Fig. 3, the gearing 10, 15 is replaced by links 19 connecting the bucket arms with a block 17 moving in guides in the block 6, or in a modification, Fig. 5 (not shown), by links 19 connected with opposite ends of a lever pivoted in the block 6. In another modification, Fig. 4 (not shown), the links 12 of Fig. 3 are connected to a common pivot on the block 6, and the sectors 11 are replaced by links extending from intermediate points on the links 12 to a second slide such as 17. In another modification, Fig. 6 (not shown), the gearing 10, 15, Fig. 2, is replaced by a plate on the block 6 slotted to receive and guide pins on the bucket arms ; or pins on the block may be guided in slotted plates on the bucket arms ; and the links 12 may be connected to a common pivot and the sectors 11 dispensed with. As shown in Fig. 7, the links 12 are connected to a common pivot 14, and one of them is also connected by a link 34 to a pin 35 on the frame 1 situated so that the pivot 14 moves in a substantially straight path 40. The links 12 may be connected to separate pivots 14 and provided with interengaging teeth as in Fig. 2. As shown in Fig. 8, frame links 26 pivoted to the grab-head at 28 have interengaging teeth, and are connected at 27 with the buckets, while the buckets are connected at 2 with a lower frame link 25, giving a better digging and opening action and increasing the travel of the closing rope owing to the movement of the grab-head towards the buckets in closing. Intermediate gears are provided between the sectors 10 and the gears 15. In modifications not illustrated, the block 6 may be connected with the grab-head by a differential drum, or by a motor and gearing, instead of pulley-tackle.

[Also in Division A3] A method of moulding a rubber sole on to a lasted upper 2 comprises bending a lower edge of the upper outwardly to form a welt and bonding thereto by stitching or gluing an insole (3), supporting the welt portion on lips 4 on outwardly rotatable frame portions 5 and bringing to the welt a mould 9, side walls 9a thereof terminating in inner downward sharp projections 9b which seat on the insole portion outwardly of the last, and filling the mould hollow 8 with rubber to be vulcanized. The mould is then moved towards the last by a cylinder 11, the sharp projections 9b cutting the insole and sealing the mould against egress of rubber. Vulcanization is then carried out by means of electric heaters (40), (41), and the upper 2 is then trimmed by further depression of the projections 9b. Alternatively vulcanization may be carried out after trimming of the upper or before trimming of the insole. Stripping is facilitated by outward rotation of frames 5. The lips (Fig. 6) are carried by two frame halves (20), (21) supported about a common axis 18, while side mould portions (31), (32) are supported against the action of a spring (37) on top of adjustable columns (29), (30) each of which is outwardly rotatable about horizontal pivots (28), (29) on a plane higher than the pivot (18). The mould bottom may be adjustable in height during vulcanization by being connected to a piston Alternatively the extent to which the vulcanized material is pressed may be adjusted by interposing an intermediate plate (42) between the bottom member (39) of the mould and its supporting plate (39).

Filed: 1935-08-15
Abstract: 461,505. Lubricating. TECALEMIT, Ltd. (Stewart-Warner Corporation) Aug. 15, 1935, No. 23000. [Class 135] In high-pressure lubricating-apparatus particularly for use in garages, a single shot of lubricant is obtained by closing the inlet to a pressure chamber after opening its outlet, and a continuous flow by a further movement of the control which again opens the inlet, the outlet remaining open. Lubricant under pressure is supplied at 5 and operation of the handle 17 depresses spindle 25 to move the spring-pressed valve member 34 downwards off its seat 36, permitting the lubricant to pass from a pressure chamber 42 of adjustable capacity by a flexible tube 11 to the bearing nipple 13. The valve 34 however immediately seats on member 39 to cut off the supply, so that in this case a small shot of lubricant only is supplied to the bearing. When the continuous supply is required, the handle 17 is pressed further (a perceptible increase of force being necessary) to a second position, valve member 34 then depressing member 39 against the action of spring 40 to open the passage. The handle 17 is pivoted on a link 19 and guided by a stud 31, acting on the spindle 25 through an adjustable screw 21, plunger 23 and leather sealing disc 24. The device may be combined with a screw piston 50 for applying pressure to clear a nipple, being isolated by a check valve 46<a> of a construction (including seating) identical with that of valve 34. In a modification, the flexible pipe 11 is replaced by a rigid pipe, the piston device 50 is omitted, and a grooved screw relieves the pressure to facilitate uncoupling. Specification 430,827, [Group XXVIII], is referred to.
