Title: Drum Practice Pad
Inventor: GREAVES ANDREW
IPC: G09B15/06
Filed: 2009-09-24
Abstract: A drum practice pad is provided which requires no other equipment, such as stands or straps, to hold the drum practice pad in place to be played. A drummer may sit on a stool or chair, place and grip the drum practice pad between his inner knees, and then play drumming rhythms. The drum pad may include one of more rubber playing surfaces, preferably comprising a large central playing surface representing a snare drum and smaller side playing surfaces representing cymbals or toms. The playing surfaces may be mounted onto a wooden base, which includes curved or angled sides to fit comfortably between a drummer's knees.

Inventor: SCHULZE HANS-JOACHIM
IPC: H01L29/10
Filed: 2009-09-28
Abstract: The thyristor device comprises a semiconductor body (1), in which a first emitter (8) of a first conduction type (p) a first base (7) of a second conduction type (n), complementary to the first conduction type (p), a second base (6) of the first conduction type (p) and an emitter (5) of the second conduction type (n) are arranged successively in a vertical direction (v) proceeding from a rear side (14) towards a front side (13) lying opposite the rear side (14). A field stop zone (70) of the second conduction type (n) is arranged between the first base (7) and the second base (6), said field stop zone having a higher net dopant concentration than the first base (7). The thickness of the thyristor can be significantly reduced for a required cosmic radiation resistance compared with conventional devices.

Title: Improvements in or relating to granular catalyst and process for sweetening a sour petroleum distillate employing said catalyst
Inventor: BROWN RUSSELL H
IPC: B01J27/06
Filed: 1956-04-03
Abstract: A granular catalyst suitable for sweetening sour petroleum distillates consists of 35-45 per cent by weight of water, 4-15 per cent of cupric chloride, and the remainder fuller's earth. The catalyst is prepared by adding an aqueous solution of cupric chloride to the required amount of fuller's earth.  The cupric chloride solution may be obtained by dissolving cupric sulphate and ammonium or sodium chloride in water.  The fuller's earth support may be a natural or acid-treated adsorbent clay, e.g. Attapulgus clay.  The sour oil is contacted with the catalyst in the presence of free oxygen, for example by the slurry process at about 100 DEG  F.  The catalyst is especially suitable for use with distillate oils containing oxygenated polar compounds, e.g. phenols; such oils are thermally cracked distallates, virgin distillates containing thermally cracked distillates, and virgin distillates of high sulphur content.  Before treatment the sour oil may be washed twice with aqueous caustic soda to remove hydrogen sulphide and then with water, or may be extracted twice with acid, neutralized with caustic soda and water-washed.  Tests are described which show that the colour stability of the sweetened oils is improved, and the loss of copper from the catalyst is decreased, as compared with processes using catalysts of lower water content or prepared by different methods. It is not necessary to use hot water to wash the treated oil, one washing with water at 34 DEG  F. being sufficient.

Abstract: 1,214,685. Valves. EUROPEAN ATOMIC ENERGY COMMUNITY. 4 March, 1968 [6 March, 1967], No. 10451/68. Heading F2V. An electromagnetic valve for discharging gas from a pressurized container 2 through an outlet conduit 15 to vacuum has a closure member formed by a metal disc 18 which is actuated by at least one coil and can move freely in the space between the outlet orifice for the gas discharged to vacuum and the bottom end of a central member 4. When a coil 13 is energized, the disc 8 is lifted from a seating ring 14 and urged against a layer 18 of resilient material on the bottom portion of the central member 4 which has a circular groove 28 to receive a flange 17 on the disc 8 and provide a reduced inlet orifice for the gas upstream of the disc 8. The valve may be held closed by a rod 29 until a vacuum has been established when the rod 29 is raised and secured by a bayonet or screwed connection to a piston 30. A negative pressure regulated by a screw 32 may be applied to the disc 8 by raising the piston 30 until it uncovers an outlet port 31. Return of the disc to its seat is assisted by energization of a second coil 10 and the image of a light source 27 reflected from the innermost turn of the coil 13 through a lens 21 and a protective glass screen 24 on to a photomultiplier indicates the period of opening. The coils are energized by an oscillatory discharge from a bank of capacitors having a capacity of 6 ÁF and loaded at a voltage of 4À5 kv. The disc may be aluminium with a thickness of 0À3  mm. and require 30Á to open 2 mm. In a simpler embodiment, the flange 17 embraces a boss at the bottom of the central member which has an axial discharge conduit, the parts 29, 30 and 32 being omitted.

Abstract: 1,096,216. Automatic frequency control systems. STANDARD TELEPHONES & CABLES Ltd. March 12, 1965 [March 13, 1964], No. 10574/65. Heading H3A. In an automatic frequency control system a frequency generator Gf produces harmonically related signal H<SP>1</SP>NU, H<SP>11</SP>NU, NU which are mixed together in a reference frequency generator G 8  to produce a variable frequency output signal HNU-pNU+MU in which pNU and MU are variable terms. This output signal is mixed in mixer H 2  with the output F v  from the oscillator to be controlled to produce an error signal which is divided down in divider Dd to result in a signal NU. This signal and the reference signal NU are then both multiplied by a constant C in harmonic generators G h1 , G 2  to produce signals which are compared to produce control signals for the oscillator. These control signals ##, C## are applied to variable capacitance diodes CV1, CV2 in the oscillator, Fig. 6 (not shown). In the error signal generator, Fig. 4, the two signals CNU are compared in a phase comparator circuit # 1  to provide a control signal C##. The signal NU from divider Dd and a further signal (C + 1) NU are fed to a mixer H 7  to produce a further signal CNU having a different phase from that derived from generator G h1 . This further signal is compared with the reference CNU signal in a frequency comparator # 2  to produce a further control signal ##. The comparature # 1 , # 2 , Fig. 5 (not shown), may be of the balanced diode type. In order to give a smooth change over between coarse and fine control an attenuation link At is provided between the coarse and fine control paths.
