Title: Hydantoic acid-formaldehyde-urea resins and their preparation
IPC: C08G12/36
Filed: 1957-09-26
Abstract: Resins are prepared from a hydantoic acid, urea and formaldehyde.  A hydantoic acid is defined as an N-carbamyl amino acid.  They may be prepared by reacting pure amino acids, or mixtures thereof as prepared from proteins, with urea in an alkaline solution, or with potassium cyanate.  Examples of hydantoic acids are N-carbamyl glycine, N-carbamyl proline and N-carbamyl hydroxyproline. Preferably the hydantoic acid is mixed with aqueous formaldehyde, the mixture heated slightly, cooled and urea added with rapid stirring. In Example 1 mixed hydantoic acids from a protein hydrolysate left after a glutamic acid extraction were heated to 80 DEG C. with aqueous formaldehyde, the mixture cooled to 45 DEG C. and urea added. After an initial drop in temperature, reaction raised it to 63 DEG C. The solid product was washed, ground and air-dried.  Example 2 is similar, toluene being added to the reaction mixture just before the urea.  Specification 867,875 is referred to.

Title: Improvements in and relating to liquid break electric switches
IPC: H01H33/14
Filed: 1934-10-25
Abstract: 435,961. Oil-break switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 25, 1934, No. 30629. Convention date, Oct. 26, 1933. [Class 38 (v)] A liquid-break switch comprises a casing containing oil or other arc-extinguishing liquid in which are immersed relatively movable contacts responsive to variations in the pressure of the liquid, the casing having a flexible wall portion co-operating with means exterior of the casing for varying the pressure of the liquid to actuate the contacts. In the form shown, the movable contact structure comprises a number of sealed hollow expansible members 7 made of conducting material, such as copper, each member containing a compressible fluid such as air. The oil pressure within the tank 1 is varied by a flexible wall portion or metallic bellows 10 connected to an operating rod 11 which is latched against the tension of a spring 12 by a latch 13 which co-operates with a tripping solenoid 14. When the latch is tripped, the spring 12 acts on the bellows 10 to increase the pressure within the tank, with consequent collapse of the members 7, to produce a series of breaks between the fixed contacts 3, 4 and contacts 9 carried by the members 7. Return movement and latching of the rod 11 removes the pressure within the tank, whereupon the members 7 expand to close the circuit, the expansion being aided by springs 8. The lateral supports 15 for the fixed and movable contact members are connected by high resistances 17 which form a shunt across the breaks.

Filed: 1972-06-30
Abstract: 1368394 Liquid level indicators ROBERT BOSCH GmbH 30 June 1972 [30 June 1971] 30655/72 Headings G1H and G1N Apparatus for monitoring the level of liquid in a container 16, e.g. the level of coolant or brake fluid in a vehicle, includes two temperaturedependent resistors such as thermistors 10, 11 thermally coupled by a layer of solder and positioned at the same level within the container, the operating characteristics of the thermistors being different (as shown in) Fig. 2 but the thermistors being supplied with differentpoteatials. A supply voltage coupled across lines 17, 18 is applied to the thermistors and to a relay 20 having a contact 21 in series with a signal lamp 22 and/or an audible warning device (not shown). When the liquid level is above the thermistors, their common temperature is low, their resistances are consequently the same, and current through relay 20 is sufficient to keep contact 21 open and lamp 22 unlit. If the level however falls below the thermistors, their common temperature rises. The resistance of thermistor 10 consequently increases more than that of thermistor 11 (to points B, A respectively), and thermistor 10 and relay 20 are starved of current resulting in the illumination of lamp 22.
