Title: Recording and or play-back apparatus
IPC: G11B15/665
Filed: 1970-07-31
Abstract: 1323171 Tape loading PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 July 1970 [4 Aug 1969] 37184/70 Heading G5R In a tape loading system, a support 20 is is rotated between the positions shown in Figs. 3, 4 to cause a post 14 to withdraw a loop of tape from a cassette 1 and then wrap one side of the loop helically around a rotary heads drum 15, as in Fig. 4. The support 20 may be rotated by a motor-driven pinion such as that (26) described with reference to Figs. 1, 2 (not shown), or may be rotated manually, e.g. using a handle (37) as described with reference to Figs. 5-7 (not shown). Figs. 3, 4 show an optional arrangement where the axis 17 of the drum is eccentric relative to the axis 23 of the support 20, the consequence being that when the support is rotated the drum, which is mounted on the support, moves around axis 23 and partially enters the cassette, as shown in Fig. 4, thereby increasing the angle of wrap at the drum. The tape reels may be co-axial as in Figs. 1-10, or par-axial as in Figs. 11, 12 (not shown).

Title: An improved process for obtaining a dry powder from a solution or suspension of a solid by centrifugal atomization
IPC: B01D1/18
Filed: 1954-12-24
Abstract: A dry non-sticky rubber powder is prepared by discharging atomized latex from a centrifugal atomizer into and in the same direction as a rotating current of heated gas, e.g. hot wood fire smoke, and at a place closely adjacent to an impeller that rotates the gas current. The wood fire smoke is preferably obtained by burning or carbonizing wood which does not contain rosin, and may be applied to the latex particles at a temperature of 150 DEG  C.  Alternatively there may be used other combustion gases to which have been added, for denaturing the protein, wood fire smoke and/or formaldehyde or phenol.  A vulcanizable rubber powder may be prepared by atomizing the latex in a hot gas containing sulphur vapour, and by using a hot gas containing chlorine or gaseous hydrogen chloride, powdered chlorinated rubber or rubber hydrochloride may be obtained.  A synthetic resin moulding powder may be prepared by atomizing a solution or suspension of phenol, urea, or melamine in a hot gas current containing formaldehyde.  Specification 802,002, [Group XXIX], is referred to.

Title: Multitone arpeggio system for electronic organ

Filed: 1972-08-11
Abstract: 1406256 Electrophonic musical instruments D H BALDWIN CO 11 Aug 1972 [16 Aug 1971] 37677/72 Heading G5J Automatic arpeggio is provided in an electrophonic organ by means responsive to actuation of selected keys to activate selected stages of a counter driven by a variable clock and means generating a corresponding tone when the count reaches an activated stage. Closure of a key switch 10 opens a corresponding gate 23, 24, 24a ... to pass a tone signal from a corresponding source 25. The outputs of each three adjacent notes are grouped and connected to a tone gate 36, 37 .... When any key is actuated a detector 21 triggers a counter 13 the stages of which are normally monostable circuits with a period of 30 Ásec. so that the counter passes from stage to stage too rapidly to open gates 36, 37 .... However when a key is operated, a potential on lead 45, 46 &c. transforms the corresponding stage of the counter into a bistable circuit which is reset by a clock (not shown). The dwell is sufficient to open the gate 36, 37 ... and pass the tone signal through formant filters 14 to a speaker 16. Actuation of a given key affects not only the corresponding signal gate, but also through diodes 51, the same note in all higher octaves so that as the counter counts a full up arpeggio is produced. The counter may be arranged to reverse at the end to produce an up-down arpeggio. The arpeggio tempo may be linked to the expression pedal. Several arpeggios may proceed simultaneously. If switch 12 is closed, shunt diodes isolate successive octaves so that only those notes actually keyed sound. The counter may be permanently stoped so that the organ plays conventionally.

Title: Character Generation System.
Inventor: GARDNER GERALD MARVIN
IPC: H04L21/00
Filed: 1968-08-08
Abstract: 1,176,778. Generating characters for printing. STANDARD TELEPHONES & CABLES Ltd. 8 Aug., 1968, No. 37940/68. Heading G4H. The invention relates to a character generating system of the kind, e.g. as described in Specification 1,142,084, in which characters are generated by a co-ordinate array of storage cores (9 columns, 15 rows) through certain ones of which a wire is threaded for each character, to set cores in a corresponding pattern, a complete line of (20) characters being printed together by setting the matrix for the first character, reading out the top row to energise appropriate dot printing heads of a wire printer, resetting the matrix for the second character, reading out and printing the top row of the second character and so on, and then repeating for subsequent rows until all the rows of all the characters are recorded. The present invention provides means for varying the spacing between characters including means for resetting all the cores of the matrix so as to obtain outputs from every column having a core set. These signals are combined with the signals from the top row to obtain an indication of the full character width which is entered in a width recorder, and applied to a counter unit. This controls the printing position of the,following character to obtain the desired inter-character spacing. Line justification may be achieved by including with the character code representing an interword space details of its required width. The width recorder detects the presence of a space code and translates it into a signal which is a function of its width. A similar space-varying arrangement may be associated with the system described in Specification 1,157,237, which uses a waffle iron store for the character shapes.

Title: Improvements in or relating to electric circuit interrupters
IPC: H01H9/10
Filed: 1957-12-10
Abstract: 843,672. Automatic circuit-breakers; switches held set and freed mechanically; switch cases. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 10, 1957 [Dec. 24, 1956], No. 38341/57. Class 38 (5). [Also in Group XXXVI] Each pole of a circuit-breaker such as that of Specifications 574,116 and 601,844, is provided with a current-limiting fuse 113 having a plunger 143 which, when the fuse blows, turns a lever 145 to move the free end of a bimetallic element 45 out of latching engagement with a spring - biased trip lever 83. Normally, an excess current close to or above the interrupting capacity of the circuitbreaker is interrupted by the blowing of one or more of the fuses and one or more tripping electromagnets 95 turns or turn a trip-bar 79 to release a lever 63 and cause the opening of the contacts 21, 23, the release of the lever 83 by the fuse preventing resetting of the trip-bar 79 and reclosure of the interrupter until the fuse has been replaced. When the fuse carrier 131 is removed to replace a fuse, a lever 161 is permitted to turn under the bias of a spring 163 into a position in which the limb 167 of the lever 161 abuts the latch 81 of the trip-bar 79 to prevent the resetting of the trip-bar. Should the carrier be removed without a fuse having blown, then the lever 161 is able to trip the circuit-breaker by turning the trip-bar. When a fuse is removed, a lever 169 is permitted to turn under the bias of a spring 179 into a position such that if the fuse carrier be replaced with any of the fuses missing, then an arm 181 of a lever 169 engages the upper end of the lever 145 and turns this lever to move the associated bimetal element 45 to release the lever 83, if not already released, so that the circuit-breaker mechanism cannot be reset and the contacts reclosed. In a modified arrangement, Fig. 6, proper replacement of the fuse carrier 131 is prevented should a fuse be missing by a lever 195 which is pivoted by a spring 191 into the position shown when a fuse is removed. The end 197 of the lever is sufficiently wide to prevent the attempted replacement of the carrier moving the lever 161, so that the tripbar 79 is still held by the lever 161 and resetting is prevented. To permit the mounting of the fuse-carrier, an insulating extension 109 is secured to the circuit-breaker base 11 by studs 110 screwed into metal inserts 112 in the base 11. Screws 117 threaded into the studs engage shoulders in bores 118 and hold the extension rigidly against the base. Mounting bolts 114 extend through openings in the studs 110 and the extension 109. Reference has been directed by the Comptroller to Specification 783,366.
