Title: An automatic metal type distributing machine
IPC: B41B3/04
Filed: 1921-10-01
Abstract: 190,818. Atkinson, T., and Day, H. C. Oct. 1, 1921. Distributing type. - Relates to machines in which the type are traversed along a selection channel containing a series of selector-heads which co-operate with nicks in the type, a type being released when it reaches the proper selector-head. The column of type is supported on a galley having a sliding base b, Fig. 4, which is advanced by a screw c to bring the end line against a fixed end-piece c<1> opposite to a channel c<2>, into which the lines are successively delivered by pushers on an endless chain. Alternatively, the galley may be fixed, and the type advanced by a spring device. The type are supported in the machine by means of recesses a', Fig. 10a, near their shoulders, and are provided with distributing-nicks a<2> on one face. The type are lifted one by one to the level of the selection channel e, Fig. 7, by a slotted plunger g operated by a cam h through a spring i<1>. The plunger contains an independently movable slotted sl-de j, Fig. 9, of a thickness equal to that of the thinnest type, and the slots in the slide and plunger are normally out of alignment so as to prevent the elevation of more than one type. The end of the line in the channel c<2> is accommodated in a sliding receiver f<1>, Fig. 4, which is retracted so as to release the end type as the plunger g ascends. The slots in the slide and plunger g are brought into alignment by a lever k<3> co.. operating with a fixed stop, and the type is pushed into the selection channel by an endless chain. The selector-heads f, Fig. 18, have ribs to engage the supporting-notches a<1> of the type, and are carried by sliding rods 0<SP>2> so that they may be retracted to release the type. Each selectorhead contains an independently sliding member r having ribs to co-operate with the distributing- nicks a<2> of the type, the members r being pushed back by the passing type. When a type reaches the selector-head to which its nicks correspond, the member s is not pushed back, and an electric circuit is completed through the type, which causes an electromagnet to withdraw the selector-head. The released types fall into tubes t' leading to a type-case or the like.

Title: Delay circuit according to the charge transfer circuit principle
IPC: H03H11/26
Filed: 1975-06-19
Abstract: 1470637 Active delay circuit ITT INDUSTRIES Inc 19 June 1975 [25 June 1974] 26104/75 Heading H3U A charge transfer delay circuit includes a first longitudinal chain of series connected charge transfer stages T 0  to T 00  to which an input is supplied E and wherein the charge transfer is controlled by a first two-phase clock # 1 , # 1 <SP>1</SP>; a second, output, longitudinal chain T 2 <SP>1</SP> to T 00 <SP>1</SP> wherein a second two-phase clock # 2 , # 2 <SP>1</SP> controls the serial charge transfer and which circuit has, interconnecting the corresponding stages in the first and second chains, e.g. T 3  to T 3 1, transverse chains each having n-series connected charge transfer stages, as T 11  to T 1n , wherein the charge is transferred in parallel fashion between the first and second chain under the control of an n-phase clock. As shown, the transverse chains need only be placed between all odd numbered stages in the first and second chains for at any one clock phase of the first and second clocks either the odd or even numbered stages contain a neutral voltage only. The arrangement is intended to provide analog or pulse delays longer than at present feasible in a single chain swing to charge loss, by decreasing the number of stages that a sample is held in, but increasing the time it remains in each of the stages. The input chain being filled, the whole contents transferred to the first stages of the transverse chains and held while the input chain is re-filled. The transverse chain being clocked down to make room for the second set of samples held in the first chain. If the full delay is not required, the clock driving the transverse chains may be applied to several transverse stages (TK1, TK2 say, not shown) to speed the transverse shift.

Title: Electrical musical instrument
Inventor: ANDERSON WALTER JOSEPH

Filed: 1958-08-15
Abstract: 900,212. Electrophonic musical instruments. LOWREY ORGAN CO. Aug. 15, 1958, No. 26330/58. Class 88 (2). In a two-manual instrument having a coupler and using thermionic-valve tone generators, each key has a movable contactor which engages an associated fixed contact when the key is depressed, positive potential for activating the tone generators being connected to the fixed contacts; the circuit is such that the fixed contact of a key of the lower manual is connected to its associated tone generator only when the lower manual key is depressed and the corresponding upper manual key is raised. As shown in Fig. 1A, closure of switch 21 couples the upper manual to the lower, the circuit ineluding the movable contactor 11 of the upper manual key so that there is no possibility of " robbing," i.e. unwanted connection between the upper bus-bar 23 and the lower bus-bar 17, through the simultaneous depression of corresponding keys in both manuals. In a modification, Fig. 2, this " robbing " is prevented and coupling effected by a gas-tube NE2 which fires with a potential difference of 120 volts but not 60 volts. In a further modification, Fig. 3 (not shown), the gas-tube NE2 is used in conjunction with a condenser and a manual or pedal control to sustain notes after the release of the corresponding keys.

Filed: 1936-09-29
Abstract: 488,023. Counting-apparatus. WAYNE CO. Sept. 29, 1936, No. 26395. Convention date, June 11. [Class 106 (i)] Apparatus comprising cost and quantity counters having a resetting mechanism and shutter mechanism for shrouding the counters during resetting has means for successively opening the shutters so that the opening of the shutter of the cost counter is delayed until after a predetermined operation of the quantity counter. The invention is shown applied to the registering mechanism of a liquid dispensing apparatus of known form with a pair of quantity counters A and a pair of cost counters B, Figs. 1 and 2. The counters are actuated by bevel and spur gearing driven from the shafts 4 and 8. A rotatable resetting shaft 12 is operatively connected bv spur gearing to the shafts 16 coaxial with the counter wheels. When the shaft 12 is rotated a cam 17 thereon rocks a bell crank lever 18 so as to operate the shutters 2, 3, to close the apertures 27, 28. The lever 18 is connected to one of the shutters 2 by means of a link 23, and a slotted link 25 connects the shutter 2 to one of the shutters 3. The link 25 has a projection 38 which, in the closed position, engages a latch 35 to hold the shutter in position. The latch 25 is secured to a shaft 32 having an arm 31 with a projection extending into the path of a pin 29 on the units disc of the counter A. At the end of the zeroizing movement the pin 29 occupies the position shown in Fig. 1. This units disc has the first four digits omitted. so that the first number exhibited will be " 5 " representing <5>/10 ths of a gallon. At this moment the pin 29 will engage and rock the arm 31 thereby freeing the link 25 and permitting the shutter 3 to move to open position under the action of the spring-controlled lever 41. The oppositely disposed shutter 2 is connected to the lever 18 by a link 46, while the shutter 3 is connected to the lever 41, the shutters being interconnected by a slotted link similar to link 25.

A method of constructing a dielectric-filled wave-guide consists in depositing on a member of dielectric material of the required shape a layer of electrically-conductive material having a thickness insufficient to provide mechanical strength but sufficient to provide electrical conductivity and applying to the layer of conducting material an insulating material having substantially the same coefficient of thermal expansion as the dielectric material and which adheres to the conductive material. A core 1 of polyethylene may be coated with silver by spraying or by electrodeposition of the metal on to a preliminary coating of graphite. The coated bar is then wrapped with an absorbent tape such as cambric on to which is applied a compound consisting-of a polyester resin loaded with an amount of finely-divided mica sufficient to make the coefficient of expansion of the compound substantially equal to that of the dielectric material. Alternate applications of tape and loaded resin are then made until a suitable wall 3 has-been built up. The resin is then hardened. Complicated configurations such as "rat-race" circuits (Fig. 1, not shown) may be made in this way.
