Title: Formation of system information medium access control protocol messages and ascertainment of system information from system information medium access control
Inventor: CHOI HYUNG-NAM
IPC: H04B10/2581
Filed: 2006-08-31
Abstract: In a UMTS base station, system information data packets (system information blocks or SIBs) received from a logical channel have associated prioritization information used to indicate the priority of the respective packet. From these packets system information medium access control (MAC) protocol messages are generated taking into account the prioritization information. By prioritizing at the level of the MAC protocol layer when mapping these messages onto a transport channel, static or slow changing system information can be given priority on a secure mobile radio channel, and dynamic or fast changing system information can be distributed flexibly using available subcarriers and transmission time intervals or not transmitted at all when there is insufficient bandwidth. A first (static) system information MAC protocol message may contain a statement indicating how a second (dynamic) system information MAC protocol message is to be transmitted, for example the frequency band or time slot.

Filed: 1945-04-20
Abstract: 597,897. Detectors. GENERAL ELECTRIC CO., Ltd., BRITTAIN, F. H., RANSLEY, C. E., and RYDE, J. W. April 20, 1945, No. 10045. [Class 40 (v)] A crystal contact for use when rectifying or mixing electrical oscillations, comprises a silicon element, the surface of which is subjected to a process of controlled oxidation to modify its electrical characteristics. In one method of manufacture, the contact surface of the silicon element is polished and may be etched by being dipped into a solution of hydrofluoric acid. The element is then heated in air to about 1050‹ C. for about two hours, allowed to cool and then again dipped in the solution of hydrofluoric acid for five minutes. The process results in the production of a thin oxide layer, part of which is later removed by the hydrofluoric acid or other oxide removing chemical agent.

Title: Electro-static methods of storing and recovering information
IPC: H01F27/14
Filed: 1955-04-06
Abstract: 786,520. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 6, 1955 [April 9, 1954], No. 10058/55. Class 106 (1). [Also in Group XL (a)] In a method of statically storing binary digital data, a spot on a dielectric target in capacitative relation to a signal plate is bombarded with a sharply established and sharply terminated electron beam, the beam being either of a first predetermined intensity whereby a static charge representative of one type of binary bit is deposited on said spot, or of a second predetermined differing intensity whereby a static charge representative of the other type of binary bit is deposited on said spot. If the velocity of a primary electron beam 26, Fig. 1, is made sufficiently high to cause the secondary emission of a greater number of electrons when it strikes a spot on a phosphor target 14 (i.e. if the secondary electron emission coefficient is greater than unity), then the electrostatic potential of the spot depends upon the primary beam intensity in the manner shown in Fig. 3. With a low beam intensity the potential of the spot is positive, point Az, Fig. 3, and with a high beam intensity the potential is negative point - B 1 . If the beam intensity corresponds to the point - B 1  and is then decreased to zero the potential of the spot will increase along the curve providing the decrease is not too rapid, and the spot will be left with a positive potential +A. With a very rapid decrease in beam intensity, however, the potential of the spot follows one of the dotted curves, and the spot is left with a negative potential - B. This phenomenon is used to store binary bits. To store a " 1 " a high intensity beam corresponding to the point - B 1  is initiated, and is sharply cut-off leaving the spot with a negative potential and to store a " 0 " a low intensity beam, corresponding to the point Az, is initiated and is sharply cut-off leaving the spot with a positive potential. Thus data storage is effected by applying large pulses to the control grid for ones and small pulses for zeros. Stored data is read by applying a burst of the low intensity beam to each spot in turn thereby bringing it to point Az, Fig. 3, and strobing the leading edge of the pulse induced in the signal plate. For non-destructive readout a recirculatory technique is used; when a zero is read the state of the spot is unchanged, left-hand side, Fig. 4, and when a one is read the electron beam density is increased to the high level for the second half of the reading period, the increase of the control grid potential being shown dotted in Fig. 4.

Title: Improvements relating to apparatus for controlling power transmission systems
IPC: F15B9/12
Filed: 1942-07-20
Abstract: 559,010. Fluid-pressure servomotors for brakes and clutches. LAYSTALL ENGINEERING CO., Ltd. and HEDGSTOCK, S. July 20, 1942, No. 10083. [Class 135] A power transmission system including either a clutch or friction brake that is operated automatically in accordance with the speed of the main power unit utilizes a servomotor, the piston or like member of which is directly controlled by one or. more valves which cut off the pressure from the piston until the speed of the power unit reaches a critical value whereupon the pressure is applied progressively directly to the piston. As shown, a clutch plate 65 is connected by a fork 3 and link 5 to the piston rod 7 of a servomotor 60. The rod 7 carries a piston 9 and sleeve 11, the latter having ports 19, 20, 21 therein which co-operate with piston valves 22, 23 on a rod 28 which is connected by a link 33 to a lever 35 on a spindle 36 entering a speed responsive unit 61. The unit 61 includes centrifugal weights 40 rotated by the main power unit and acting on a sleeve 42 connected by an arm 44 to the spindle 36. When the engine is idling the rod 28 is in the position shown in Fig. 2, oil under pressure supplied to a pipe 13 being unable to pass through the port 21, while both sides of the piston 9 are open to an exhaust pipe 32. Thus the clutch is held disengaged by a spring 76. When the engine speed reaches a predetermined value the weights 40 fly outwardly and the rod 28 is moved to the right, Fig. 2, and oil pressure passes through the passages 14, 15, 16, 21; 20, 29 to the left side of the piston 9 and engages the clutch. Manual control means for actuating the servomotor comprises piston valve parts 46, 47, 48 on a rod 45 which is actuated by a solenoid 52 energized upon closure of a switch 53 on a speed control handle 54. When the solenoid 52 is energized the rod 45 is moved to the left so that valve part 47 closes port 16 and part 46 opens port 51 to the pipe 32 thus relieving the fluid pressure on the piston 9. Specifications 395,692, 421,894, [both in Group XXIV], and 446,014 are referred to.
