Title: Improvements in card indexes
IPC: B42F17/00
Filed: 1932-02-18
Abstract: 389,260. Card indexes. REMINGTON RAND, Inc., 465, Washington Street, Buffalo, New York, U.S.A. Feb. 18, 1932, No. 4891. Convention date, Feb. 18, 1931. [Class 146 (i).] Card indexes, more particularly of the overlapping visible-index type, are provided with folding cards such that each card which is adapted to be folded to reduce its width between the side edges comprises three portions, consisting of two outer end portions and an intermediate foldable portion, which when folded reduces the card to a width substantially corresponding to the combined widths of the two end portions. The card 32, Fig. 2, is formed with fold portions 38 as shown and may be attached to the card support 20, Fig 1, by inserting the side extensions under the slit 33, the lower end being received in a celluloid pocket 28. The supports 20 are maintained in overlapping relation by inter-nesting supporting lugs 23 attached thereto by wires 24, which engage beneath slots 26 in a tray 27. The cards may be formed with single fold portions, half the width of those shown in Fig. 2, and two cards may be mounted side by side in one support. In the modification shown in Fig. 10, lugs 68 are provided to hold the card in its folded position, these lugs engaging in slots 69. Lugs 64 engage slots 63 on the adjacent card, to hold the cards interlocked in overlapping relationship, the top card being similarly held on a support. A single fold portion may be used in this modification, and the fold may be cut down the centre line, after connecting the two parts of the card by the interlocking lugs 68 and slots 69. Perforations 22, 60 on the support 20 or the card 50 permit the card to have a hinging movement. Other attachment means described comprise clips hingedly attached to supports carried by guides provided adjacent each side of the record members, the free ends of the clips being inserted through holes on the card supports 20 ; alternatively, the cards may be attached to their supports by keyhole slots which by flexing the cards are caused to engage hollow rivets attached to the card supports.

Title: Device for the synthetic testing of the breaking capacity of high-voltage power circuit-breakers
IPC: G01R31/333
Filed: 1969-01-31
Abstract: 1,263,733. Testing switches. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Jan. 31, 1969 [Jan.31, 1968; Feb.28, 1968], No.5460/69. Heading G1U. In an arrangement for the synthetic testing of the breaking capacity of a very high-voltage power circuit-breaker PS, there is superimposed on a transient voltage developed across the tested breaker after a test current interrupted thereby has become zero and commencing before the transient voltage reaches its maximum, an additional transient voltage such that the resulting combined transient voltage matches the test voltage necessary for the tested breaker. The arrangement comprising a high-voltage oscillatory circuit III for supplying both the additional transient voltage and an auxiliary current which includes a current frequency determining capacitor C H, a normally closed auxiliary breaker HK which is also connected in a circuit containing the tested breaker, and voltage determining elements REK, CEK in parallel with the auxiliary breaker HK. As the test current to be interrupted by the tested breaker approaches zero, an auxiliary current with the same polarity is applied to the tested breaker by the high-voltage oscillatory circuit, this auxiliary current becoming zero at the moment when voltage superimposition is required to commence, at which time the auxiliary breaker HK is opened and the capacitor CH in the high-voltage oscillatory circuit is short-circuited, such that the transient voltage determining elements REK, CEK initiate the generation of the additional transient voltage. In one embodiment Fig. 1, high current is applied to the breaker PS under test from a transformer T via an auxiliary breaker HS in a circuit I. As a current zero is approached HS is opened at time to to isolate the high current and a spark gap F1 fired to apply a transient high voltage from an oscillatory circuit CE, LS to the test breaker (circuit II). Spark gap F2 is then fired at time t 1  so that current from a source capacitor CSK is applied to charge the capacitor CH in the high voltage oscillatory circuit and auxiliary current flows through the tested breaker. The tested breaker PS is then opened at time t 2  to interrupt the auxiliary current. F3 is then fired at time t 3  and HK is opened so that the auxiliary transient voltage across capacitor CEK is added to the transient voltage from circuit II. In a second embodiment Fig. 2 (not shown) the auxiliary breaker HS and first high voltage circuit are dispensed with, and the breaker HK with its associated components is included in the series path between the current source and the test breaker. Another arrangement Fig. 4 (not shown) is similar to that of Fig. 1 but the breaker HK and its associated components is in series with and on the earth side of the test breaker relative to the current source.

[Also in Divison D1] Apparatus for removing residual yarn from spent bobbins includes a receptacle 66 for accommodating at least one spent bobbinfrom, for example, a loom L via shoot 40-and a conveyer 90 for lifting bobbins individually from receptacle 66 to bobbin stripper 10. The conveyer comprises a slider 94 movable vertically between tracks 92, 93 by chain 100 which has a pin engaging in a horizontal slot in the slider 94. On the slider there is pivotally mounted an arm (116), Fig. 7 (not shown) carrying a magnet. When the slider moves down past receptacle 66 a cam plate (130), Figs. 4-6 (not shown), swings the arm (116) outwardly from the waiting bobbin, but, when the slider has passed the receptacle, arm (116) causes a catch plate (132) (Figs. 4-6) to release cam plate (130) so that arm (116), as the slider returns upwardly, can move inwardly for the magnet to lift the waiting bobbin which has metal rings R around the butt end. A further cam plate (150) (Fig. 7) swings arm (116) outwardly from receiver 156. However, on the downward journey the bottom end of the bobbin is caught by an end wall of the receiver 156 causing the magnet to release the bobbin. The bobbin falls down shoot 180 into bobbin stripper 10.
