Title: Delayed-start grid responsive load
Inventor: HOWE ANDREW
IPC: H02J3/14
Filed: 2009-07-08
Abstract: A smart responsive electrical load (10) is operatively connectable to an electricity supply network (20). The said smart responsive electrical load (10) comprises an electrical power-consuming device (30) and a control arrangement (40) for controlling a supply of electrical power from the network (20) to the device (30). The control arrangement (60, 110, 150, 160, 170) is operable to impose a variable time delay (tp) before supplying electrical power to the device (30) after a request for power to be provided to the device (30). The variable time delay (tn) is a function of a state of the network (20), for example its frequency (t) and/or its voltage amplitude (V). Optionally, the device (30) is a battery charger, for example for use with a rechargeable electric vehicle. Beneficially, the smart responsive load (10) is supplied with electrical power from a population of micro-generation devices (500) operable to provide supply network response.

Title: Rotary transmission coupling having a hydraulically actuated friction clutch
Inventor: MAY ERIC
IPC: F16D25/0638
Filed: 2009-09-29
Abstract: A rotary transmission coupling 1 is disclosed for selectively providing drive to an output such as a driven wheel (115, 116, fig 1) of a motor vehicle. The rotary transmission coupling 1 includes a friction clutch (2, fig 2) and a hydraulic actuator assembly (20, fig 2) that receives fluid at pressure from a remote pump (206, 216, fig 17) controlled by an electronic control unit (202, fig 17). The actuator assembly includes a hydraulic actuator formed by a body 21 that slidingly supports a piston 25 used to operate the friction clutch. The body 21 is restrained from rotation by a number of spigots (24, 35, 36, fig 2) that allow limited translation of the body 21 to accommodate tolerance build-up within a transmission assembly (123, fig 12a) of which the rotary coupling 1 forms a part. The hydraulic actuator is attached to a clutch cover 4 of the friction clutch 2 such that the reaction force from the hydraulic actuator is resisted solely by the clutch cover 4 and is not transferred to any other components of the rotary transmission coupling 1. Thrust bearing 32 is located between the piston 25 and the clutch thrust member 33.

Title: Valve for steam trap
Inventor: VIVIAN TOM
IPC: F16T1/02
Filed: 2009-10-06
Abstract: A valve element for a steam trap comprises an expansion chamber in the form of a metallic bellows 32 having a variable axial length and having first and second ends sealed with first and second end caps 34, 36 respectively. A valve closure member 58 is provided on the second end cap and is arranged to cooperate with a valve seat (26, Fig. 4). A first guide member 38 is coupled to the first end cap and axially extends into the bellows and a second guide member 40 is coupled to the second end cap, axially extends into the bellows and cooperates with the first guide member. This allows relative axial movement between the first and second end caps 34, 36 but restricts relative radial movement between the first and second end caps. This ensures that the valve closure member 58 seats properly on the valve seat 26.

Title: Two piece interlocking fitting for fixing and securing a frame to a wall
Inventor: LAVERY PETER CAWTHORN
IPC: A47G1/16
Filed: 2009-10-15
Abstract: A fitting for securing a mirror or picture frame to a wall comprises two pieces that interlock. The first piece is a domed fitting (Fig 1) which is attached to the wall with a screw passing through its centre. The inner surface of the screw creates pressure against the domed fitting inner flange forcing it to increase in size when pressure is applied. The second piece is attached the frame and is a vaulted (i.e. top-hat type) bracket/plate (Fig 2), with an oval hole to allow for sideways movement. In use, the domed fitting passes through the hole in the bracket, compressing slightly and opening out again when through the hole. The fitting can be unlocked with a wedge shaped key (Fig 4, Fig 8) that slides inside its vaulted bracket squeezing the domed fitting down in size. This enables it to fit back through the hole in the vaulted bracket. To enable easy installation the vaulted bracket is has a sharp area (B, Fig 7) protruding from it. First, the bracket is attached to the frame and then the frame with the bracket attached is offered up to the wall. The sharp area marks the wall so that the correct position for the screw for the domed fitting can be determined.

Part of the inner liner of a refrigerator is spaced from the insulation to form a chamber in which the evaporator defining the freezer compartment is positioned. As shown in Fig. 2, the liner is spaced from the insulation 16 at the top right-hand corner of the cabinet to form a chamber 22 of which the side wall 24 and the bottom 26 are formed by the liner and the remaining walls by the insulation. The part of the liner has a flange 36 defining an access opening to the chamber 22. A U-shaped evaporator 42 is positioned in the latter with the open part of the U directed towards the side wall 24 to which the limbs of the U are attached by. flanges 44. The top, side and bottom walls of the evaporator are spaced from the insulation 16 to define air-flow passages 60, 62 and 64, air being admitted to the passages through slots 66 at the top of wall 24 and returned therefrom to the storage compartment 18 through slots 68 at the bottom of wall 24.

A further valve 25 may be adapted to be actuated by a lever 37 at the driver's volition to prevent or allow the automatic change to the by-pass train. A simple hydraulic coupling may be used instead of a torque convertor with either a by-pass train or a direct drive clutch and in one arrangement described a direct drive dog clutch for a convertor is adapted to be actuated electrically by movement of a vehicle accelerator pedal to a certain position so that the direct drive is obtained at a certain output torque, a manual over-riding control is also provided. The automatic change-over may be effected in accordance with both speed and output, the valve 25 or an additional valve being actuated by the accelerator pedal or other member controlling engine output. The governor mechanism is preferably a snap-action one which provides for an up-change at different speed to a downchange. The accelerator pedal control may also be such as to give a different control on movement in one direction than in the other. Electromagnetic clutches may be utilised instead of friction or dog clutches.

Title: Improvements relating to circuit arrangements for sampling electrical waveforms

Filed: 1966-03-11
Abstract: 1,112,853. Multiplex pulse signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 21 Feb., 1967 [11 March, 1966], No. 10828/66. Heading H4L. In a circuit for sampling electrical waveforms in which each of a plurality of sampling gates is connected across a main (signal) highway and a bias current-highway, the latter is connected to means for determining a selected level of bias current, and each gate is arranged so as when open to pass current through itself between said highways and includes means for applying an amplitude modulating signal to the bias current passing through the gate. The arrangement ensures that the bias level does not vary from gate to gate by an extent greater than the permitted difference determined by the input characteristic of a co-operating P.C.M. coder. As shown a plurality of sampling gates G1 to GN are connected between the main highway MH and a bias current-highway BCH, the main highway being connected via a transistor T1 to a coder. A transistor T2 is connected to the bias current highway BCH and in conjunction with resistor R determines the value of the bias current through the gates, resistances Rg being relatively small. The gates are opened sequentially by pulses of opposite polarity from source CPS applied simultaneously to terminals t 1 , t 2 . Normally diodes d 1 , d 3  are conducting due to quiescent potentials from source CPS and the resultant current through Rg causes diodes d 2 , d 4  to be backed-off. Channel timing pulses back-off diodes d 1 , d 3  so that diodes d 2 , d 4  conduct and the input signal supplied via terminal t 3  and capacitor C amplitude modulates the bias current I b  flowing through the gate. In practice, stray capacitance SC exists and also switching of the channel gates may overlap for part of a channel period and to avoid the consequent variation of bias current a low-impedance path is provided by the emitter-collector path of a transistor T3 connected between highways BCH and MH. The current flow in transistor T1 is held constant at I b  so that any variations in the values of resistors Rg is taken up by variations of current through T3.
