Title: Phonographic audio-visual teaching machine
IPC: G11B31/00
Filed: 1969-03-12
Abstract: 1,215,098. Audio-visual teaching apparatus. McGRAW EDISON CO. 12 March, 1969 [13 March, 1968], No. 12963/69. Heading G5G and G5R. A sheet (146, Fig. 1) carrying visual items and with associated index marks (157) along one edge is mounted on the top plate (140) of an apparatus comprising a movable pick-up head assembly 66 for playing back a rotating spirally-grooved record 28, an index head 17 arranged so that its movement into alignment with any selected index mark (157) causes the pick-up head to move to the start position of a recorded message corresponding to the selected index mark, and a handle 20 mounted on the index head 17 and movable relative to the index head into a position in which it initiates playback of the selected message. In this "start" position the handle 20 is engaged in a slot between two teeth 82 of a comb 81, thereby latching the index head 17 in the selected position. Movement of the handle 20 from the start position to an intermediate position, in which it is still between the two teeth 82, causes the pick-up head to be lifted from the record 28, the record drive to be stopped and the pick-up head to be reset to the start position corresponding to the setting of the index head 17. As shown in Fig. 3, the index head 17 sets the pick-up head assembly 66 by means of a pantograph linkage 86, 85, 98, the arm 98 having a stepped edge 101, each step corresponding to a latched position of the index head 17. In modified constructions, the pantograph linkage is replaced by gearing and a driving screw (Figs. 17, and 18) or by a rotary stepping cam (Fig. 19). The record 28 is inserted and removed through a slot between two guides 29a, 30a. The detection of a recorded tone of predetermined frequency stops the playback at the end of the selected message. The apparatus consitutes a teaching machine, particularly applicable to the teaching of languages.

Abstract: The invention comprises saturated and unsaturated 3,11,18,20,21 - penta - oxygenated-9a -halo-pregnanes and functional derivatives thereof, particularly 9a -chloro or fluoro derivatives, and a process for their preparation wherein a 9 : 11 unsaturated 3,18,20,21-tetraoxygenated pregnane or a functional derivative thereof is treated with an agent capable of introducing hypohalous acid by additive combination at the 9 : 11 double bond, if necessary the resulting 9 : 11-halohydrin is reacted with a dehydrohalogenating agent and the 9 : 11-epoxide formed reconverted into a 9 : 11-halohydrin by the action of hydrogen halide, and if desired any of the oxygenated groups are converted into other free or functionally converted hydroxyl or oxo groups.  Specified functional derivatives include esters, ethers, their thio analogues, acetals, hemiacetals, ketals, enol esters and ethers, enamines, hydrazones, semicarbazones, aldehyde-bisulphite compounds, particular compounds being D 4-3,18,20-trioxo-11b ,21-dihydroxy - 9a  - fluoropregnene, D 4 - 3,18,20 - trioxo - 11b ,21 - dihydroxy - 9a  - chloropregnene and their 21-monoesters. Suitable halohydrinforming agents are the hypohalous acids, their salts, esters and ethers, haloacetamides, haloimides and haloamines, while the halohydrins can be converted to 9,11b -epoxides with aluminium oxide, tertiary bases, e.g. pyridine, collidine or hydroxides or oxides of metals of Groups 1 and 2 of the Periodic system, e.g. silver oxide.  Hydroxyl groups in the products may be esterified, e.g. with acetic, trimethylacetic, propionic, valeric, enanthic, undecylenic, benzoic, phenylpropionic, or cyclopentylpropionic acids, or etherified, e.g. with carbohydrates. In an example: D 4,9(11)-3,20-dioxo-18,21-diacetoxy-pregnadiene is treated with N-bromoacetamide in t-butanol giving D 4-3,20-dioxo - 9a - bromo - 11b  - hydroxy - 18,21 - diacetoxypregnene which with silver oxide in pyridine followed by re-acetylation yields D 4 - 3,20 - dioxo - 9,11b  - oxido - 18,21 - diacetoxypregnene, subsequent treatment in dioxane with HCl gives D 4-3,20-dioxo-9a -chloro-11b -hydroxy - 18,21 - diacetoxypregnene, and with HF the corresponding 9a -fluoro derivative.  D 4,9(11) - 3,20 - Dioxo - 18,21 - diacetoxypregnadiene is prepared from D 4-3,20-dioxo11b ,18,21 - trihydroxypregnene by treatment with POCl3 in pyridine and acetylation of the resulting D 4,9(11)-3,20-dioxo-18,21-dihydroxypregnadiene.
