Title: Electric load control
IPC: H02J3/14
Filed: 1975-10-23
Abstract: 1512555 Maximum demand circuits J G OLSEN 23 Oct 1975 43667/75 Heading H2H A system for limiting the peak loading on an electrical supply system comprises means for sensing the load requirements on the system or of one of the backs and switching off the less essential loads when the sensed load tends to exceed a given maximum value. A supply system comprises supply conductors 10, 12, 14 to which are connected loads 16, 18, 20, the load 16 being directly connected to the supply conductors, the load 18 by way of a triac 22 and the load 20 by a pair of back-to-back thyristors 38, 40. Whilst the total load in the system is below the desired maximum a relay 52 remains un-energised so that contacts 32, 36, 46, 50 are in the positions shown, the gate circuits being such that the triac 22 and thyristors 34, 40 are conductive and all three loads 16, 18, 20 are supplied from conductors 10, 12, 14. Should the load 16 demand power such as would overload the system, the output of the current transformer 54 is sufficient to energise the relay 52 to change over contacts 32, 36, 46, 50. The gate potentials of the devices 22, 38, 40 are then such that the devices become non-conductive to disconnect the loads 18, 20 from the supply conductors 10, 12, 14. Alternatively the current transformer 54 may be placed in the supply conductor 14 and furthermore the main loads may be switchable as well as the less essential loads, the control being by way of two relays, the operating coils of which are connected in series and of different operating levels.

Title: Improvements in or relating to Machine Milking Installations

Abstract: 1,172,150. Milking machines. ALFALAVAL A.B. 6 Oct., 1967 [19 Oct., 1966], No. 45679/67. Heading AIM. A vacuum operated milking installation (Fig. 1, not shown) incorporates a transfer unit connected between the milking unit (i.e. a teat cup claw and cluster) and the milk transport line by which milk is delivered e.g. to a releaser. The transfer unit collects milk: it also incorporates means operative to close a passage between the milking unit and the transport line and at the same time admit air to the latter such operation being repeated periodically during milking so that air pressure can be used to force milk from the transfer unit into the transport line without loss of vacuum at the milking unit. The vacuum source which supplies suction at the milking unit is also connected, independently of the milk transport line, to the upper end of the transfer unit. Fig. 2 shows one form of the transfer unit having a top connection 38 to a vacuum source, a bottom connection 37 to an evacuated milk transport line and a connection 40 to the milking unit. A pulsator 5 controls the required variation of the milking vacuum and also reciprocates a rod 7 which is connected to a valve element 3. This valve element opens and closes an opening 8 between an upper milk receiving chamber 1 and a lower discharge chamber 2 of the transfer unit. When valve 3 is open milk from the cow is sucked into chamber 1 and runs out into chamber 2. When it is closed, milk continues to accumulate in chamber 1 and an extension 9 on the rod 7 carrying valve element 3 opens an air inlet 4 in chamber 2 to facilitate passage of milk to the transport line. This air cannot leak back into chamber 1 and so there is no loss of milking vacuum. In various modifications (Figs. 3 to 6, not shown) the second chamber may be beside, not below, the first and the periodic operation of the valves may be controlled by air pressure and/or by a float whose position varies with the amoung of accumulated milk in the device.

An electron probe X-ray microanalyser includes means for adjusting the position of the test sample 5 and an optical microscope having an objective lens 13 movable between a viewing position and a position where it is clear of the electron beam. In use, the point of incidence of the electron beam is first made visible by allowing the beam to bake on to the sample surface a substance such as oil vapour or fine organic substance floating in the vacuum chamber. The microscope is then moved to the viewing position and adjustable cross-wires are aligned on this point, following which the sample is moved until the area to be examined lies under the cross-wires. The microscope objective is then returned to the dotted position allowing electron beam e to strike the selected area. As shown, only the objective lens tube 11 is moved, by screwed rod 15, but in an alternative arrangement (Fig. 3, not shown) the complete microscope is slidable through the chamber wall. The alternative also includes a beam deflecting arrangement whereby the X- ray detector can be placed normal to the surface of the sample.

Abstract: 1,274,674. Indicating door bolt. EVERED & CO. Ltd. 6 Oct., 1969 [4 Oct., 1968], No. 47090/68. Heading E2A. An indicating dead bolt is provided with a sliding pressed sheet metal bolt 20 and a rotatable operating member 29 operatively connected with a pressed sheet metal eccentric element 33 which cooperates with the bolt to effect translational movement of the latter between a fastening and releasing position in response to rotation of the rotatable operating member. On turning the rotatable operating member 29, which is external of the front plate 11 of the casing 10, on spindle 28, in an anticlockwise direction, the eccentric element 33 keyed on to the spindle is rotated, thus moving the bolt 20 to the left by the action of the inwardly projecting tongue 34b engaging in the slot or hole 36 in the bolt 20 or vice-versa; the bolt being guided in its translational movement by tongues 11a projecting from the front plate 11, by the slot 27 in the bolt 20 sliding around the spindle 28, and by the exit hole in the fore-end plate 13 of the casing 10. The lock may be reversed for projection of the bolt to the right by turning the bolt 20 over so that the other side is face to face with the front plate 11 and turning over the eccentric member 33 so that the tongue 34a engages in the slot 36 and the faces 33a, b engage the edges 12 towards the left hand end wall in Fig. 2, the end 24 of the bolt 20 engaging a keeper. An indicator device is provided on the opposite side of the door in which the cover (10) is provided with semicircular discs 47a, b coloured red and green and the opening 42 is provided with a mask 43 rotatable with the spindle 28 and having an aperture 45 therein so that in the release position, green is observed at 45, and red is observed in the fastened position. In emergencies the lock may be released from the outside by insertion into the aperture 45 of, for example, a pencil and rotation of the mask 43.
