IPC: H02H7/093
Filed: 1933-04-11
Abstract: 415,202. Glass manufacture. DICHTER, J., 8, Hauptstrasse, Sch÷neberg, Berlin. April 11, 1933, No. 10853. Convention date, June 15, 1932. Divided on 408,450, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 27, 1933. [Class 56.] Relates to apparatus for feeding lengths of glass tubing to a machine for shaping or working them, the tubes being withdrawn one at a time from a shoot and carried by a swinging transferring-device into line with a chuck on the shaping machine. According to the invention, the transferring device, as it comes into register with the shoot, operates a shutter that delivers a tube laterally into grippers on the transferring-device, and the tube is removed from the grippers by an ejector which pushes it longitudinally into engagement with the chuck. The transferring device comprises an arm 3 which is pivoted at one end to a block 2 and carries at its free end a pair of gripping- jaws 5 that are connected to one another by a pair of parallel links 6 pivoted on the arm 3. The glass tubes 10 are stored in a shoot 9, and the outlet of the shoot is provided with a shutter 11 mounted on a pair of parallel links 12, one of which is provided with an upwardlyextending arm 12<a>. When the arm 3 is raised, as shown in Fig. 1, the shutter 11 is below the mouth of the shoot 9, and a glass tube rests on the upper edge of the shutter and is kept there by a stop plate 13. When the arm is lowered, a projection 14 on one of the links 6 strikes a stop 15, carried by the base of the machine, and separates the grippers 5. At the same time, the arm 3 engages the arm 12<a> and raises the shutter 11, so that the glass tube rolls over the strip 13 into the grippers 5. A spring 8 closes the grippers, when the arm 3 is raised, and holds the glass tube until the arm arrives in the vertical position. The grippers are then opened by a member 17, forming part of the linkage that moves the arm 3, which engages an extension 25 of one of the links 6. As soon as the grippers are opened, a plunger 27, which slides through a boss in the machine base, rises and pushes the glass tube longitudinally out of the grippers into engagement with a chuck on the shaping machine.

Abstract: 1,210,339. Automatic volume control. SIEMENS A.G. 3 March, 1969 [4 March, 1968], No. 11116/69. Heading H4R. In the pilot controlled gain regulation system of Specification 1,178,517, in which a single pilot receiver is used to scan sequentially a number of communication channels and to feed pulses to respective control circuits in the channels to increase or decrease the attenuation in the channels, and maintain the pilot level constant, the control circuit in each channel comprises, as shown in Fig. 2, a switch 11, e.g. a transistor, which is closed by a "discharge" signal and open during a "charge" signal, and a second switch 7 operated at regular intervals to connect the capacitor store 8 to the chargedischarge circuit. The charge circuit comprises a diode 1, forwardly biased during charging, and a resistor 2, while the discharge circuit comprises a diode 3, forwardly biased during discharging, and the emitter collector path of transistor 4, whose base bias is derived from a potentiometer 5, 6, across the D.C. supply terminals. The charge in the capacitor 8, provides the gate voltage of F.E.T. 14 whose source drain impedance is connected in the feedback path of the amplifier to control the channel gain. The charge-discharge circuit arrangement provides a substantially constant variation of gain with each charge or discharge pulse. In an alternative charge-discharge control circuit, Fig. 3 (not shown), the switch 7 is a change-over switch with the additional fixed contact connected to the same reference potential point as that to which the capacitor 8 is returned. In addition, the resistor 9 is returned to a tapping between the resistor 6 and an additional resistor (10) connecting resistor 6 to the negative supply so that the adjustment of the upper limit of control and of the charging current can be adjusted simultaneously by varying that resistor (10).

Abstract: 233,349. Aktiebolaget Ljungstr÷ms Angturbin. April 30, 1924, [Convention date]. Universal joints.-In order to permit relative movement between a hollow gear shaft 5 and a wheel axle 8 power is transmitted from the shaft to the axle through a tapered sleeve 8 by means of a universal coupling at each end of the sleeve, each coupling comprising push rods non-rigidly connected to their respective parts and acting in the direction of their length. In the construction shown each end of the sleeve 8 is provided with three radial arms 9 spaced midway between corresponding arms on one end of the shaft 5 and one of the wheels (as shown) or the wheel axle. The rods 13 act only as push rods and their ends enter freely detachable sockets 18 in the ends of the radial arms, thus transmitting tangential force or torque from the shaft to the sleeve and the sleeve to the axle while permitting other angular and axial relative movements of the parts. The rods may be hollow and have hardened end pieces to take the wear, or their ends may be hardened for this purpose. Either these ends or hardened plates in the sockets are provided with part spherical surfaces to allow the rods to rock freely, these surfaces having a radius greater than half the length of a link. It is stated that there is thus a tendency, when the rods are rocked, for them to return to their normal positions. The Specification as open to inspection under Sect. 91 (3) (a) states also that the connection between the driving and driven members is effected by links movably connected with their respective means and acting in the direction of their length. This subject-matter does not appear in the Specification as accepted.
