Abstract: 268,874. Hole, S. Jan. 7, 1926. Receiving and delivery devices for doers and the like.-A parcel-receiving apparatus for doors &c. comprises a container, having one or more compartments, which is urged by gravity or a spring to move in one direction across an aperture in the door &c. and is normally held against such movement by a part operatively connected with the closure member of the aperture such part permitting the container to move, when the closure member is opened, on to or against a support by which it is retained in a position ready tor the reception of a parcel through the aperture. As shown the container 20 has a number of compartments each provided with a hinged and spring-pressed member 55 having lugs 57, 58, the lugs of one member being supported. when the closure member 33 of the aperture 32 in the door is closed by spring-controlled latches 50 slidable in the member 33. On opening the member 33, for the delivery of a parcel into the container, the latter drops a short distance until the member 55 engages a ledge 52 at the top of the aperture 32 and supports the container with a compartment opposite the aperture. When the member 33 is closed, the latches 50 temporarily lock it and engage the lugs 57. 58 to push the member 55 off the ledge 52; the container with the parcel then falls until the lugs of the next compartment engage the latches and allow the member 33 to be opened for the next 'delivery. When the last compartment has been used and the member 33 closed, the latter cannot be opened until the container is raised and reset. The container, which may be arranged to slide horizontally, is provided with ribs 37, 38 slidable in V-shaped guides 35, 36 fixed behind the door and the friction of the ribs in the guides may be regulated by a spring-controlled plunger 42 arranged in the guide 35. The latches serve as shock-absorbers and the sudden descent of the container may also be prevented by a spring- controlled bell-crank lever pivoted to the guide 36 so that an arm thereof is engaged and moved against the action of the spring by one of a series of stops carried by the container. A rack and pawl arrangement 70, 71 may be provided to prevent the container from being raised by a person outside the door and an alarm may be provided to indicate when the container has descended to its lowest or an intermediate position. The member 33 is hinged at the bottom of the aperture 32; it may be spring-controlled and provided with means for holding it in a line with the bottom of the aperture to form a shelf.

Title: Improvements in or relating to electrical generating plant
IPC: H02J3/00
Filed: 1958-01-06
Abstract: 884,992. Automatic control systems for power stations operating in parallel. BROWNLEE, W. R. Jan. 6, 1958 [Jan. 7, 1957], No. 534/58. Class 38 (4). [Also in Group XXXVI] An electrical distribution system having a number of generating plants connected thereto of the kind disclosed in Specification 884,991 has the computing apparatus modified to operate with the incremental transmission loss ratio reduced to a linear function of the phase angle between the voltages at the plants in each pair. The computer shown in Fig. 1 is in three similar sections and in comparing plants 1 and 2 there are fed to the receivers 110, 210 voltages representing the phase angles of the voltages at the bus-bars thereof, the receivers 110, 210 being arranged to control, by means of mechanical linkages 109, 209, the sliding contacts 108, 208 on potentiometers 102, 202 respectively; these potentiometers being fed with a voltage derived from a transformer 101 having a sliding contact 105 on its secondary winding which is adjustable by a control knob 106 thus allowing the introduction of a constant term into the computer. Thus the voltage obtained between the sliding contacts 108, 208 is representative of the incremental transmission loss ratio for plants 1 and 2 which ratio is linear with respect to the phase angle between the bus-bar voltages of plants 1 and 2. The incremental generating cost ratio for plants 1 and 2 is obtained by means of receivers 118, 218 responsive to the actual outputs of the plants, which receivers control potentiometers 112, 212 so that, after a fuel price index has been introduced by a control knob 122 into the computation, a voltage appears on the conductors 126, 127 which is representative of the incremental generating cost ratio for plants 1 and 2. The voltages representing the two ratios are then compared and any deviation from economic balance between plants 1 and 2 is shown on an indicator 130. Similarly indicators 230 and 330 show any deviation from economic balance between plants 1 and 3 and plants 1 and 4 respectively. Should unbalance be indicated, any adjustment necessary to restore balance may be made manually or automatically similarly to the arrangement disclosed in Specification 884,991. As an alternative the data supplied by receivers 110, 210, 310, 410 may be obtained by the use of a network analyser. In a further embodiment the incremental generating cost ratio computation may be modified to take cognisance of the fact that a generating plant may exist in the system between the two plants being compared. Specifications 884,993 and 884,994 also are referred to.

Filed: 1988-01-05
Abstract: PURPOSE:To obtain a light emitting diode having high brightness and efficiency with excellent reproducibility, by selecting the total period of a growth time for an n-layer after growing a p-layer and the time for holding the layer at a high temperature in the same growth atmosphere after growing the n-layer so as to satisfy a specific relationship in liquid epitaxial growth by a temperature gradient method. CONSTITUTION:A temperature difference is provided between a p-melt containing Zn as a p-type impurity and Al and GaAs as growth materials melted therein and an n-melt containing a metal to be an n-type impurity and Al and GaAs as growth materials melted therein to bring a substrate crystal into contact with the low temperature side of the melts. The substrate crystal is then held for a prescribed time to grow a p-Ga1-xAlxAs layer and n-Ga1-xAlxAs layer on the substrate. In the process, the following relationships is satisfied. That is the total period [t (min)] of the growth time for the n-layer after growing the afore-mentioned p-layer and the time for holding the layer at a high temperature in the same growth atmosphere after growing the n-layer is determined from the composition (x) of the n-Ga1-xAlxAs layer and t=alpha.exp(-beta.x)+ or -33% (alpha=417, beta=1.9).
