Abstract: 1,268,769. Flanging. BENJAMIN OAKES & CO. Ltd. 5 Feb., 1970 [6 Nov., 1968], No. 52603/68. Heading B3Q. A press comprises a body 10, Fig. 1, with a wedge-shaped slot 12 for a wedge-shaped gripper 13 adapted to grip a workpiece to which a presstool 31 or 32, Figs. 5 and 7, is to be applied, and an abutment 21 movable relatively to the body 10 to urge the gripper 13 towards the broader end of the slot 12 for removal of the workpiece. As shown, the workpiece is a tube 38 an end of which is pressed into the divided gripper by one end of the tool 31, Fig. 5, to form a bead, and by the other end of the tool to form the bead into a flared end, Fig. 7. A saddle formed by the abutment 21, a toolholder 22 and connecting bars 23 is slidable relatively to the body 10 by means of a screw 20 engaging threads in the saddle or body 10. With the gripper 13 retained in the slot 12 by a keeper 15, a tube to be flared is placed in the gripper and pressed endwise by a gauge 31, Fig. 1, located by a groove 32 in a yoke 30 of the toolholder. The gauge 31 also contacts the gripper, Fig. 4 (not shown), moving it along the slot until it grips the tube. With the tube thus located and gripped, the gauge is replaced by the tool 31 for performing the beading and flaring operations, Figs. 5 and 7.

Title: Disc painting and advancing apparatus
IPC: B65G47/14
Filed: 1973-11-19
Abstract: 1424932 Conveying discs on edge LEWALS Inc 19 Nov 1973 [20 Nov 1972] 53678/73 Heading B8A [Also in Division B2] Discs D are advanced on-edge in a columnlike relation from a feed shoot 72 along spaced rotating support rollers 26, 27. The leading disc is sprayed by a paint gun 10 and is discharged to a shoot 96. The discs D may be advanced in the shoot 72 by gravity, or by rotating feed rolls 80, 80. The leading three discs are engaged by a pressure roller 85. This has a flange which holds the leading disc momentarily. When a predetermined degree of back pressure develops in the column, the roller 85 is lifted against the action of a spring 92. The spray gun 10 is operated in response to a signal from a switch 112 operated by a lever 87 on which the roller 85 is mounted. In order to facilitate the discharge of each disc, the roll 27 is longer than the roll 26, by an amount equal to the thickness of one disc. In a modification (Fig. 8), the roller 85 is replaced by a flexible abutment 132. The leading disc is first held by this and is then deflected upwardly (against the spring of the abutment), by the action of a disc 138 carried by an arm 136, periodically reciprocated by an eccentric 144. There may be a third roll 42 (Fig. 2) supporting with the roll 27 a second column of discs. Deflecting mechanisms as in Fig. 8 may be provided (Fig. 10, not shown) for each column with the arms 136 operating in an out of phase relationship, so that the load on the paint supply can be evened out. The actual operation of each spray gun is initiated in each case by a switch 150 (Fig. 8) operated by a lever 142 connected to the arm 136. The feed of paint to the spray gun 10, is controlled by a unit (16) (Fig. 1, not shown). This has a control 106 for adjusting a delay period between the initiation signal (i.e. by switch 112 or 150) and the instant at which the valve of the gun is opened. A knob 108 controls the duration of the spray period. When the discs are discharged, they are fed to a drying oven (24). The feed rolls 26, 27, are mounted so as to be held in a slightly sloping attitude (up or down) by adjusting a knob 63 (Fig. 2).

Abstract: 1,246,509. Automatic exchange systems; prepayment substations. TAMURA ELECTRIC WORKS Ltd. 20 Nov., 1968 [25 Nov., 1967], No. 55016/68. Heading H4K. In a prepayment substation, a capacitor C2 is charged via resistors R1 and the line wires from central battery E whenever the handset is lifted. A.C. tone reverted over the line by closure of contacts 3 (as, for example, when a called party replies) is detected by a tuned circuit consisting of capacitor C1, transformer 6 and diode D1 so that when capacitor C3 is sufficiently charged a transistor 7 is slowly turned-on. Capacitor C2 thereafter discharges through the transistor and a coincollecting relay 8 which is thus brought-up in order to energize a coin-collecting mechanism (not shown). Instead of a coin-collect operation, the relay may operate a counter for counting the number of calls.

A torque converter 22 which drives shaft 18 through gears 30, 32 and clutch 36, also drives shaft 20 through gears 30, 34 and clutch 38 and drives a pump 24, supplying pressure fluid to the torque converter and clutches, through gears 26, 28. Gear 68 drives output shaft 16 through gear 72. Each clutch is engaged by pressure fluid acting on a piston 48 which press plates 46 together to connect the hub 40 to the drum 42 through the plates 46. Selective engagement of clutches 36, 38, 66 and 70 provides two forward and two reverse speeds. In another embodiment which provides three speed ratios in forward or reverse a countershaft 74, Fig. 3 (replacing countershaft 18) has a gear 76 fixed thereto in constant mesh with a gear 84, rotatably mounted on a shaft 80, which can be clutched to shaft 80 by engagement of a clutch 86 integral with a gear 94 which meshes with a gear 96.

In Fig. 1 a rotating disc having different transmissive sections 7 and 8 alternately passes radiation of sample and reference wavelength ranges from a source 1 to a detector 3 through a test chamber 4. A sample gas or liquid flows through the chamber 4. An optical wedge 10 having different absorption coefficients for the sample and reference wavelength ranges is moved in or out of the beam in accordance with the detector output and the position, indicated at 21 and recorded at 22, indicates the absorption of the sample beam by the gas or liquid. The movable wedge 12, filter 15 and windows 5, 6 are made of similar material to that of wedge 10 and are used to set the zero of the analyzer. Wedges 11 and 13 are of neutral material and avoid the beams being deflected.

Abstract: 1362640 Electrophonic musical instruments CHICAGO MUSICAL INSTRUMENT CO 12 Dec 1972 [27 April 1972] 57294/72 Heading G5J An electrophonic musical instrument is arranged to fill in, when a melody note and accompanying chord are played, notes that are octavely related to the notes of the chord and are 3 to 11 semitones below the melody note. As described, the instrument has a first series of key switches 23 operated by the accompaniment manual and a second series of key switches 25 operated by the melody manual. Each tone generator (of which two, 15 and 16 are shown) may be gated to an output system 11 either by a switch 43 actuated by the corresponding key or by a signal from a corresponding one of transistor switches 27. When a chord is played on the accompaniment manual, keying potential is applied to the emitters of all the transistors corresponding to all the notes of the chord in all octaves. When a melody note is played, earth is connected to the base of the transistor corresponding to a note 7 semitones below that played so that if the emitter of that transistor has keying potential from a switch 23 this potential will pass to open the corresponding gate 18. The chain of resistors 41 ensures that the bases of the four transistors on either side will be sufficiently earthy to pass keying potential, thus allowing any notes marked by switches 23 and lying 3 to 11 semitones below the melody note to sound.
