Abstract: 1345367 Crystallizing apparatus; epitaxial deposition WESTERN ELECTRIC CO Inc 19 April 1971 [16 March 1970] 24031/71 Headings B1G and B1S [Also in Division C1] An apparatus provides a four step cycle for growing a crystal on a substrate 44, from a melt 45 in a compartment 61, by cooling the substrate with heat exchanger 77. A slider 51 and boat 59 of pure graphite are loaded with a source mixture 54 for doping the melt, and a melt mixture 62, covered by a lid 65. The boat is slid on to a base member 41 carrying the substrate 44 and after positioning two stop bars 50, 55, the assembly is placed in a furnace 74 so that the substrate 44 overlies heat exchanger 77. On moving slider 51, inwardly, Fig. 4B, both the mixture 54, in slider recess 56 and the substrate 44 are sealed in, to prevent degradation, while the melt mixture 62 is fused. In the 4C position, the melt 45 is saturated with the mixture 54 before being moved into contact with the substrate 44 (Fig. 4D). Crystal growth takes place, as heat exchanger 77 is supplied with coolant gas, in order to establish a vertical temperature gradient in melt 45. In order to stop crystal growth, the slider 51 is pulled back to the 4E position, thus depositing part of the melt 45 in base compartment 47. The apparatus may be used for producing a p-type epitaxial layer of Ga P on a p-type Ga P substrate, from a Ga solution doped with n and O 2 .

Abstract: 854,100. Coin-freed vending apparatus. TELEFONBAU UND NORMALZEIT G.m.b.H. July 15, 1959 [July 19, 1958], No. 24315/59. Class 27 A vending machine, particularly for beverages, has an electric motor M or electro-magnet for operating the delivery means and an inserted coin 27 momentarily moves a switch 1 to contact 42 to prepare a circuit for the motor or magnet and the return of the switch to contact 38 after the coin has passed closes the circuit to the motor or magnet. Momentary operation of the switch energizes a relay R and holding circuit and the relay armature moves a guide plate 12 about a pivot 13 so that subsequently inserted coins are deflected down a shoot 7 to a coin-return outlet 23 and a cam surface 14 on the plate 12 moves a flap 16 about a pivot 20 so that a flange 19 is moved clear of a slot 36 through which the operative coin falls for collection. When the coin clears the switch 1, the motor is energized through the contact 38 and rotates until a cam 41 opens contact 34 and closes contact 44, thus de-energizing the relay R and supplying a braking current through a variable resistance W and the armature current circuit of the motor. A switch 3 enables the relay and motor to be operated continuously when, for example, loading the machine and a lamp L is illuminated by a switch 4. In a modification, inserted coins pile up in a pocket of which the depth is adjustable by a pin selectively fitted in several holes in a lever. The last coin operates the switch but, prior to insertion of the last coin, a coin-return button can be pressed to move the lever and allow return of the stored coins.
