[Also in Division B6] In a machine for printing on or coating with paint or otherwise treating e.g. tubular objects 11 carried by spindles 5 . . . 10 on an intermittently moving rotary carrier 4, a sensing device 12 is provided at a station in advance of the treatment position, and if an object is absent at that station causes a signal which is stored until that station reaches the treatment position whereupon the signal causes operation of mechanism for stopping or rendering inoperative the treating apparatus. As shown, a cylinder I causes sectors 2, 3 for printing on the objects 11. At each step forward of the carrier 4, a cam 13, Fig. 3, coupled to the carrier 4 closes contacts 14 whereby relays 16 cause a stepping switch 18 to move forward one step at each step forward of the carrier 4. If absence of an object is detected by the device 12 on, as shown, spindle 7, contacts are closed to send a signal to the switches 18, which when the object reaches the printing position, and a cam 19 on cylinder 1 closes a contact 20, causes relays 28 to be actuated to operate a device 21 stopping the cylinder 1 or moving the sectors 2, 3, to an inoperative position. At the same time a signal is sent to a restoring relay 17 to render that relay inoperative. If objects are present on spindles 8, 9 &c. following the spindle 7, then during further movement of the carrier 4, another cam 22 coupled to the carrier closes contacts 23 which through the relays 17, 28 actuate the device 21 to render the printing apparatus operative again.

Title: Process for the after-carbonation of phenolic oils containing alkali
Inventor: BEMMAN RUDOLF
IPC: C10G17/09
Filed: 1959-06-29
Abstract: A process for the after-carbonation of alkaline phenolic oils comprises treating the oil with gaseous carbon dioxide to convert the alkali into an alkali bicarbonate the gaseous carbon dioxide and the phenolic oil running in parallel current.  The alkaline phenolic oil may be obtained by extracting a phenolic oil with an alkali and subsequently gassing the resulting phenolate with carbon dioxide i.e. carbonating, to give a phenol containing sodium carbonate.  The carbon dioxide and phenolic oil are preferably passed at 30-50 DEG C. and at 1.2-2.5 abs. atm. pressure through an empty tube or a tube fitted with baffle plates and the phenolic oil separated from the bicarbonate sludge.  Any excess carbon dioxide may be recycled to the initial carbonation.

Title: Improvements in or relating to sodium cyanide
Inventor: KREMER VINCENT WILLARD
IPC: C01C3/10
Filed: 1956-07-18
Abstract: Crystalline sodium cyanide is obtained by the evaporation of an aqueous solution of sodium cyanide below atmospheric pressure, while maintaining in the solution between 0.2 per cent and 3 per cent of sodium hydroxide to prevent the liberation of free hydrogen cyanide. The temperature employed is preferably between 56 DEG  C. and 70 DEG C.  A cyclic process is described, in which the sodium cyanide is obtained by neutralizing sodium hydroxide solution with hydrogen cyanide.  After partial evaporation the sodium cyanide crystals are filtered off and the filtrate is returned partly to the evaporator and partly to the neutralization step so that the concentration of the sodium hydroxide in the evaporator is kept within the permissible limits.

A support for the front of a trailer comprises a pair of legs 1 pivotally connected to a shaft 2 sup ported by brackets 5 and plates 25 upon a turntable 21 mounted at the fore end of the trailer. The legs 1 carry a shaft 6 having wheels 7. An articulated lever 8, 9 is pivotally connected to each leg 1 and to a plate 26 extending from the adjacent member 25, the sepa rate portions 8 and 9 of each lever being articulated together by a shaft 12 upon which is mounted a roller 13 and a pair of arms 17 formed at their one ends with catch members and at their other ends carrying a plate 18.
