Key 13 is the emergency stop key, and switch 14 is the automatic restarting switch. Switch 15 when closed cuts out the automatic control and allows the machine to run till the cards are exhausted, and when open automatically interrupts the operation at the end of a card group. Switches 12<a>, 14a and 15a are connected up as shown to function correspondingly to switches 12, 14 and 15. Lamps 19, 20 and 21 are provided to indicate at the desk the condition of the operation. Lamp 19 is lighted only while the tabulating motor is running; lamp 20 when the reset motor is running; and lamp 21 is in a circuit with the switch 12<a>. If the switch 12<a> is closed, i.e. in the position opposite to that shown, lamp 21 will never be lighted, this being the position for automatic resetting and total taking. If the switch 12<a> is in the position shown the lamp 21 will light up when the tabulator stops at the end of a group, warning the operator that the reset key should be depressed. If all lamps are extinguished the starting key should be operated.

In an example levulinic acid, phenol, hydrochloric acid and methyl mercaptan are reacted to produce 4,4-bis(4-hydroxyphenyl) pentanoic acid.  In another example levulinic acid, phenol and 37% hydrochloric acid are placed in a pressure bottle and methyl mercaptan bubbled in and the bottle sealed.  After 6 hours reaction glacial acetic is added and the reaction then continued for 18 hours to produce 4,4-bis(4-hydroxyphenyl) pentanoic acid.

Abstract: 847,120. Brake discs. AMERICAN STEEL FOUNDRIES. June 18, 1957, No. 19180/57. Class 103 (1). In a brake disc comprising a brake ring 4 made up of interconnected plates 8, 10 having braking surfaces 12, 14 on their outer sides, the inner periphery of the outer plate 10 is connected by an annular integrally formed bell-shaped web 26 with the outer periphery of a supportiug hub 6 of the wheel 36 located adjacent the inner plate 12 whereby substantially balanced thermal characteristics are established in both of said plates through the conduction of heat into the supporting hub and as the inner plate is cooled on its external side by air drawn into the disc and as the opposed sides of both plates are cooled by air blowing between the plates. The spaced plates 8 and 10 are interconnected by radially disposed blades 16 which give the structure the necessary strength and by a plurality of radially displaced vanes serving as auxiliary braces and which provide extensive surfaces for radiating heat generated in the plates 8 and 10 and to implement the blower action of the disc. The vanes 20 are provided with V-shaped notches 22 and 24 in the radially outer and inner extremities of the vanes such that each vane 20 has its widest area in alignment with the central portion of the plates 8 and 10, thereby providing maximum heatradiating surfaces for these areas of shortest distance thereto.

Title: Improvements in or relating to servo-devices of the differential air pressure type
Inventor: BRADBURY FREDERICK JAMES

Filed: 1956-06-20
Abstract: 811,229. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO. Ltd. June 3, 1957 [June 20, 1956], No. 19185/56. Class 103 (1). In order that the servo-action of a pneumatic servo-unit 17 for hydraulic brakes may become operative with a comparatively light hydraulic pressure from the master cylinder 22, such pressure acting by way of connection 33, chamber 22 and port 53 in the space behind the rear end 51 of the slide valve spool 46, first moves the valve against a light spring 64. Movement of the slide valve spool 46 in chamber 38, then by coupling ports 41 and 42, admits atmosphere to the chamber behind the piston 29 of the servounit which, as shown, is of the " vacuum-suspended " type. The thrust rod 28 is then moved to close, with its end, port 27 in the piston 26 and the subsequent increase of hydraulic pressure in front of the piston is transmitted through passage 58 so as to react on plunger 56, and move it against spring 62, which is stronger than spring 64. The spindle 57 on plunger 56 is thus made to react on the inside face of the slide valve spool and give " feel " to the operator.
