Title: Energy saving in a network processor
Inventor: KUO SHIEH-HSING
IPC: G06F1/32
Filed: 2008-04-02
Abstract: A network processor includes a transceiver circuit 311, a network data processing unit, and a clock signal control unit 34. The transceiver circuit transmits and receives a network signal, compares a voltage level of the network signal with a threshold value, outputs a comparison result, and operates under a first clock signal. The network data processing unit is coupled to the transceiver circuit to process the network signal, and operates under a second clock signal different from the first clock signal. The clock signal control unit disables supply of the second clock signal to the network data processing unit when the voltage level is smaller than the threshold value, and enables supply of the second clock signal to the network data processing unit when the voltage level is not smaller than the threshold value. The network processor may be adapted for connection to a computer system that includes a basic input/output system (BIOS) 36 and may send commands to the BIOS via a general purpose input/output (GPIO) causing it to output control signals to the clock signal control unit.

Title: Sash window restrictor having a protruding member and retaining mechanism
Inventor: DERHAM MICHAEL
IPC: E05B63/20
Filed: 2008-09-18
Abstract: A sash window restrictor 20, 120, has a housing 22, 122, which is to be let into a vertical frame member (10, fig.1) to limit movement of a sash window. A sash obstructing tab 24, 124, is mounted in the housing and obstructing tab can be retracted into the housing so as not to block a sash or extended from the housing to stop a sash. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. The sash abutting tab may be mounted for pivotal or sliding movement and may be spring biased into the extended blocking position or moved due to gravity. The obstructing tab may be positively held in the retracted position by a latch mechanism such as a push-push mechanism whereby a first push withdraws the tab and a second push extends the tab; the second push either being manually pressed by an operator or actuated automatically by the passing of a window to the closed position to automatically release and extend the tab blocking subsequent movement toward the open position. A timing mechanism may be used to provide a predetermined delay prior to releasing the tab from the retracted position. Instead of a latching mechanism the tab may comprise a damping means to slow the movement of the tab and provide a delay between movement from the retracted position to the extended position. A second lock may be provided to lock the tab in the extended position. The pivotal embodiment may have multiple coil spring biased sprocket wheels and include a clutch mechanism.

Title: Generating a second clock signal from a first clock signal based upon a delayed control signal
Inventor: SASAKI TSUNEKI
IPC: G11C7/22
Filed: 2008-10-30
Abstract: A dock signal generation circuit 700 receives a first clock signal CLK and a control signal (ctl_en or pre_wr_RAMCLK) based on an address ADDR are inputted. A second clock signal RAMCLK based on said first clock signal is generated after a delay of predetermined time from said input of the control signal. The described embodiment refers to a control circuit 10 for connection between a memory controller 100 and memory 200 which comprises the clock generation circuit, a control signal generation circuit 600 and a latency control circuit 500. The latency controller has a latency register 520 into which is stored a latency value and a latency counter 510 which decrements the value to zero whereupon the latency controller outputs a signal enabling the clock generator. The latency value can be programmed by the memory controller based upon the type of operation being performed such that the delay in generating the clock signal can be greater for write operations than read operations. This is to secure a setup time for write operations without unduly delaying read operations and prevent setup violations.

Abstract: 474,575. Uniting metal to ceramic material by heat. BRITISH THOMSONHOUSTON CO., Ltd. April 8, 1937, No. 10046. Convention date, April 8, 1936. [Class 36] In a method of producing a vacuum tight joint between metallic and insulating bodies a gaseous composition of a metal is passed through the gap between insulating body and metal body, and the metal is caused to be deposited in the gap tc fill it up. Suitable gaseous compositions are the carbonyls, for example iron carbonyl In the example ar insulator 1 for the current lead-in of ar iron rectifier is adapted to be closed at the top by an iron cap 2 which fits closely thereon and forms a carrier for the lead-in conductor, and a cylindrical member surrounding the lower part of the insulator is provided with a flange 3 which is to be welded to the vessel of the rectifier. The assembled parts are set into a vessel 4 containing liquid iron carbonyl 5 which is evaporated by slight heating, so that the vapour flows through the gaps between the insulator and the metal cylinders encompassing it. The flow of vapour can be furthered by covering the structure with a hood 7 which can be evacuated. Heating- windings 6 are provided around the cylindrical parts of the cap 2 and flange 3 to heat the gaps through which the vaporized iron carbonyl flows to a temperature of approximately 500‹ C., at which temperature the carbonyl is decomposed, iron being precipitated to close the gaps. To improve the adhesion of the precipitated iron on the porcelain insulator 1, the latter may be metallized beforehand.

Title: Electric motor control arrangement
IPC: H02P7/292
Filed: 1970-03-03
Abstract: 1280764 Control of D.C. motors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 March 1970 [6 March 1969] 10146/70 Heading H2J [Also in Division G3] The armature of a commutator motor 1 is supplied from an A.C. source 2 through a controlled rectifier 4, whereby the mean rectified voltage applied to the armature is proportional to the control voltage between terminal St and earth. A signal Vi, representing the armature current, is amplified and transmitted with inverse polarity to the terminal St through rectifier 8, when the signal exceeds a threshold value. The speed of the motor is stabilized by comparing tachometer voltage Vt with reference voltage Vr at point 15 which is connected through differential amplifier 17 and rectifier 21 to the terminal St. A bias voltage Vp is taken from a potentiometer 23, a positive feedback voltage g being obtained by smoothing the armature voltage in an integrating network 24, 25. When the source 2 is suddently switched-on with the armature 1 stationary, the rectifier 21 blocks the signal Vr and the transient armature current is restricted to a peak value determined by the signal Vp. The time constant of the network 24, 25, is made large enough for the increase of armature current to be limited by negative feedback. The rectifier circuit 3 may comprise a diodecontrolled rectifier bridge, with or without a free-wheeling diode. In a modification, the rectifier circuit comprises two fully controlled rectifier bridges so that the motor may be reversed without changing the polarity of the field excitation. The rectifier 21 is replaced by a resistor to provide operation of an intergrating nature. The components 24, 25, are replaced by a double R.C. filter associated with a network for ensuring that the feedback signals have the correct sign for all operating conditions. The rectifier operates as an inverter to provide regenerative braking, Fig. 2 (not shown).

Title: Improvements in and relating to electric relay and/or controlling systems
IPC: F42C19/12
Filed: 1940-06-11
Abstract: 585,911. Valve relay circuits; aerials. GENERAL ELECTRIC CO., Ltd., LORD, W. B. H., ROLLIN, L., TOMLIN, G. M., and TURNER, H. C. June 11, 1940, No. 10153. [Class 40 (v)] [Also in Group XXI] In a relay or control system for controlling the release and/or detonation of aerial bombs or torpedoes, the rise in effective impedance of a transmitting aerial on receipt of reflected waves thereon when it approaches a half or multiples of a half wave-length to the reflecting body is utilized to produce a desired indication or control. In the case of a bomb, the transmitter may be housed in the bomb, the aerial opening out from a folded position after release of the bomb. Three circuit arrangements are described. In the first, the rise in impedance of the aerial A energized by the oscillator V1 causes increase in current and therefore in voltage drop across a resistance R1, thus altering the grid-cathode potential of valves V2, V3, the anode circuits of which includes the operating coil of the relay R2. In the second, an audio-frequency oscillator is arranged to modulate the high-frequency oscillations supplied to the aerial and the voltage variations produced therein by change in impedance are, after rectification, fed to a low-frequency amplifier through which the desired control is effected. In the third arrangement, two aerials oscillating at different frequencies are employed in association with two D.C. amplifiers so interconnected that a paralysing bias is applied by one amplifier to the other except when a rise of impedance occurs in both aerials simultaneously. Thus, the arrangement responds only when the distance between the aerials and the reflector corresponds to a selected multiple of a half wave-length.
