Filed: 1967-06-27
Abstract: 1,137,333. Garage lifts. JOYCE-CRIDLAND CO. 27 June, 1967, No. 29484/67. Heading B8H. A vehicle lifting structure comprises a pair of horizontal vehicle supporting arms 20 pivotally connected to the outer portion of each of two bolster plates 10, 12 which are supported at their inner facing portions, on top of vertically movable powered rams. In the lowered position of the rams, the arms 20 are swung outwardly to give clearance for a vehicle being driven into position over the structure, ready for elevation. The arms 20 are then pivoted into position under the vehicle, whereby tiltable pads 24 mounted on structures 22 slidable along the arms 20, are positioned to engage the vehicle upon elevation of the rams. A lip 36 on the pivoted end of each arm engages a slot 34 in a plate 32 secured to each bolster plate. Stop pins 28 may be provided on the bolster plates to limit the inward swing of the arms 20. The movement of the rams is synchronized by a rack and pinion mechanism.

Title: Improvements in process relating to the oxidizing of oxidizable substances with atomic oxygen
IPC: C10G19/08
Filed: 1954-10-14
Abstract: Sour gasoline to be treated flows through a line 1 to a packed tower 2 where it is given a caustic alkali treatment to remove hydrogen sulphide, caustic soda being periodically introduced into the tower 2 at 4 and withdrawn at 7.  The gasoline then flows to a packed tower 8 supplied with caustic soda at 12, and continues to a knock-out drum 10.  The spent caustic leaving the tower 8 at 13 is circulated by a pump 15 through <PICT:0763661/III/1> an eductor 17 connected to an electrolytic cell 21 producing atomic oxygen which is induced by the flow of caustic to mix therewith, when mercaptides in the caustic are converted into disulphides which are subsequently removed in a scrubber tank 27, the regenerated caustic then flowing back to the tower 8.

[Class 146 (ii).] In a secret electric telegraph system a key for each letter is associated with contacts m mounted on rotatable discs and after the depression of a key for the transmission of a letter the discs are rotated and introduce a new code system for the subsequent signal. At the receiving station a similar apparatus has code contacts mounted on discs and so arranged that on depressing the key corresponding to the arriving secret signal, the intended or decoded letter is reproduced and the discs are stepped round. Corresponding to the scheme shown in Fig. 3, discs 5 mounted on a shaft 4 are associated with keys A, B, C, ... and carry contacts representing the letters shown in the vertical columns. Each key, mounted in a casing 9 on a spring- pressed rod 12, has a disc 14 with a second disc 15, pivoted at 15<a> and integral with a vertical arm 16 carrying a contact finger 8. On initial depression of the disc 15, the finger 8 is brought into contact with a contact strip on a disc 5, and on depression a sequence of currents corresponding to the Morse system is transmitted to the lines 21, 22. On release of the disc 15 with the key in the depressed position, a spring 17 brings the finger into contact with a strip 18 completing a circuit through an electromagnet 27. A pawl 30 attached to the armature rotates a ratchet wheel 31 on the discshaft thus bringing into the zone of operation of the keys a new code corresponding to a lower row of the scheme shown in Fig. 3. The armature 29 closes through a contact 38 the circuit of an electromagnet 33 which applies a brake 32 to limit the rotation of the discs. The circuit of the electromagnet 27 is broken on release of the key 14, 15. At the receiving station, on depression of the key corresponding to an arriving secret signal, the decoded letter is reproduced by contacts arranged according to the scheme shown in Fig. 4. The discs are rotated in steps as at the transmitting station to bring a new code combination into the zone of the receiving keys.
