Abstract: 198,120. Maxwell, F. March 14, 1922. Roller mills.-A machine for crushing and shredding sugar cane comprises a pair of pressure rollers with means for adjusting their relative positions, with or without pressure-regulating gear, and a third shredding-roller working in conjunction with one of the pressure rollers with pressure-regulating gear. A trash-turner may be provided to direct the crushed cane issuing from between the pressure rollers to pass between one of the pressure rollers and the shredding-roller. As shown in Figs. 1 and 3, the crushing or pressure rollers c are driven through reduction gearing b from a shaft a, and the shradding-roller j is driven at high speed by belt gearing h from the shaft a. Wedge adjusting-devices k are provided to vary the distance between the rollers c, and spring-pressure devices m for moving the water-cooled bearings n of the roller j towards one of the rollers c. The sugar cane is passed down a shoot o and after being crushed by the rollers c is shredded by the high-speed roller j. A casing r confines the shreds of cane and delivers them to a conveyer q, while a trough p catches the juice expelled from the cane by the rollers c. The top crushing roller is placed vertically above the other, and the lower crushing-roller acts as an abutment for the shredding-roller. In a modification, Fig. 4, the crushing-rollers care set at an inclination, and the crushed cane is guided by a trash-plate t to between the upper roller c and the shredding-roller j. The spring devices m press the bearings n towards the upper roller c, and by adjusting the nuts u the opening between the shredding-roller and the upper roller c can be regulated. One of the crushing-rollers may have a circumferentially-grooved surface, or it may have zig-zag circumferential gutters as described in Specification 17534/15, and the other crushing-roller is provided with teeth or projections and grooves of any known form.

Title: Improvements in or relating to electric lighting systems for motor vehicles
IPC: B60Q1/14
Filed: 1927-03-18
Abstract: 282,246. Ter Cock, C. March 18, 1927. Controlling consuming devices.-A solenoid switch under control of a hand switch, on the steering wheel for example, effects the extinction or dimming of head lights and the alternative illumination of side, spot and road lights, the switch having two coils in parallel with the headlights, one of which coils is automatically cut out of circuit to diminish current consumption, when the solenoid has operated. The system is applicable to single or double-pole systems of winding, to series and resistance dimming systems, to fused or unfused lamp circuits and does not interfere with the normal control of the lamp circuits by the usual switches. The solenoid switch comprises two coils 13, 14 wound in reverse senses and adapted to be earthed at their junction in the case of single-pole systems, but wound in the same sense for double-pole systems. The coils are readily removable from the side of the magnet frame 17, being retained by a thin brass tube 15 which encloses the plunger, fits tightly in an opening in the rear end of the frame and is retained upon one stop 20 by a second stop comprising a removable dust-cap 21. The plunger 16 actuates a spring controlled insulating block 19 carrying contacts 23 - - 26 engaging spring fingers 30 - - 38 carried by a contact holder 29. Guide rods 27, 28 fixed in the contact block have insulated leads which engage a spring finger 40, normally in contact with the rear end of finger 36, to interrupt the circuit and the coil 14 when the solenoid core has made its stroke. All the solenoid switch connections pass through a terminal block which by means of loose links may be used to effect interconnections between lamp circuits as well as serving to connect these circuits and the controlling switches. Fig. 1 shows an arrangement for single pole circuits controlling head lights 6, 7, side lights 4, 5 and auxiliary lights (spot light, road lights, &c.) 8 - - 11. Head and side lights are normally lighted by closing switches 3<1>, 2<1> respectively in the usual way and the auxiliary lights may, by a switch 44, be connected to the circuit controlled bv the switch 2'. The solenoid switch is controlled by closing a switch 12. The head light circuit passes through normally closed contacts 30 - - 33, a parallel circuit passes through contacts 36 and 40 to coil 14 and another directly through coil 13. These two circuits are completed through the switch 12 which is closed when desiring to change the lighting. The plunger 16 then opens the head-light circuits and that of coil 14 at contacts 30 - - 33 and 40 and the side lamp circuits are closed independently of the switch 2<1> at contacts 36, 38; contact 27 lights the auxiliary lamps independently of the switch 44. Modified arrangements of wiring are described for other lighting systems. The contacts 34, 35 are employed when dimming the head lamps. An auxiliary switch may be fitted to the terminal block to control the dimming device independently of the solenoid switch.

Title: Process for the manufacture of 3.5-diiodo-4-hydroxy-acetophenone and its derivativessubstituted in the oh-group
IPC: C07C49/84
Filed: 1936-03-13
Abstract: 3 : 5-Diiodo-4-hydroxy-acetophenone is prepared by subjecting 4-hydroxy acetophenone to the action of iodinating agents, of which the preferred example is iodine chloride.  If desired, the hydroxyl may also be substituted by such residues as alkyl, alkoxy, alkyl-carboxy, aryl, and heterocyclic residues.  Such substitution takes place by the interaction of salts of 3 : 5-diiodo-4-hydroxy-acetophenone in alcohol or benzene suspension with the corresponding halogenides, or by direct interaction of the components without the use of solvents.  In an example, a dilute hydrochloric acid solution of 4-hydroxy-acetophenone is treated with a hydrochloric acid solution of iodine monochloride. The 3 : 5-diiodo-4-hydroxy-acetophenone separates and is crystallized from ether or chloroform.  The compounds are useful as disinfectants and pharmaceutical products particularly X-ray contrast media.  Samples have been furnished under Sect. 2 (5) of (1) 3 : 5-diiodo-4-methoxy-acetophenone made by heating the potassium salt of 3 : 5-diiodo-4-hydroxy-acetophenone with methyl iodide in alcoholic solution; (2) 3 : 5-diiodo-4-ethoxy-acetophenone made in a similar manner to sample (1) using ethyl iodide; (3) 3 : 5-diiodo - 4 - hydroxy - methyl - ether - acetophenone made by treating a benzene solution of 3 : 5-diiodo - 4 - hydroxy - acetophenone with chloromethyl ether; (4) 3 : 5 - diiodo - 4 - hydroxy-ethoxy-acetophenone made by heating together on the water bath 3 : 5-diiodo-4-hydroxy-acetophenone and ethylene chlorhydrin; (5) 3 : 5-diiodo-1-aceto-4-phenoxy-acetic acid made by boiling under reflux the potassium salt of 3 : 5-diiodo-4-hydroxy-acetophenone and chloracetic acid ethyl ester to give the ethyl ester of 3 : 5-diiodo - 1 - aceto - 4 - phenoxy acetic acid, which on hydrolysis with strong hydrochloric acid gives the corresponding acid.
