Patent GB-1561750-A (GB)
Title: Security bolt seals
IPC: G09F3/03
Filed: 1976-11-18
Abstract: A bolt seal for securing hasps on trailer truck doors and/or rail car doors which utilizes a round or oval head bolt which extends through the hasps and upon which a nut is threaded. The nut is threaded onto the bolt until it is tight and then a hollow tube is used to bend the bolt sharply to about 90 DEG  just under the nut. Identification number areas are formed at the tail of the bolt and on a flat portion of the bolt adjacent the head. If a thief tries to break the seal by bending the bolt back to its original straight condition, the metallurgy of the bolt is selected so that the bolt breaks off. This indicates that the seal has been tampered with and furthermore, the thief finds that if he tries to turn the nut the round head of the bolt will rotate and since the threads are upset by the bending he will be unable to remove the nut. A modification of the invention utilizes a spin nut which is cylindrical in shape.

Abstract: 1287414 Mounting printing plates; registering M HART and M HART Jnr 5 Sept 1969 [11 Oct 1968] 48443/68 Heading B6C A method of registering printing plates on a cylinder relative to a flat lay-off table comprises the use of slidable members which carry pointers for use in association with the cylindrical surface and pointers for use in association with the flat table. In the apparatus shown in Fig. 2 a cylinder is geared to rotate whilst rolling over a flat table 3. In an alternative arrangement the cylinder rotates about a fixed axis and the table moves. Two blocks sliding on rails 26, 27 are provided and each carries a pointer directed towards the table and a pointer directed to the cylinder. Positions on the lay-off table can therefore be easily transmitted to corresponding positions on the cylinder. The cylinder is translucent and fitted with an interior light. Two blocks, interconnected by adjustable means, may be mounted on each pair of rails 26, 27. In the apparatus of Fig. 5 the lay-off of the design takes place on the same cylinder positions selected by one pointer being transmitted to the other pointer as the sliding blocks are fixedly spaced relative to each other.

Title: Milking machinery control apparatus
IPC: A01J5/017
Filed: 1973-10-29
Abstract: 1451215 Milking control L A HARMAN 29 Oct 1973 [9 Nov 1972] 50127/73 Heading AIM A milking control for automatically releasing the teat cups when a predetermined time interval between successive pulses of milk has been exceeded comprises a capacitance probe having a vertical, plastics, ceramic or glass tube 18 insertible in a drop line near a sight glass. The probe monitors the flow of milk by measuring the varying capacitance in the tube. The tube 18 has a Venturi region 19 with a constricted throat 20 and a frusto-conical surface 7 surrounding the upper end of the throat 20 to reduce run-back of the milk. Embedded in tube 18 are a pair of electrodes 22, 23. The former is a copper ring coaxial with the tube 18, embedded beneath a layer of adhesive or epoxy resin, and having a pair of diametrically opposite apertures 26 to accommodate a tube 27 of dielectric material which houses the other electrode 23 exposed to the milk. Thus the electrodes 22, 23 form a capacitor. Another embodiment comprises a capacitor formed in the neck of the sight glass 12 by a pair of electrodes 34, 35 each being a copper ring coaxial with the passage 20'. Extension 33 surrounds the exit of the throat 20' to reduce run-back of milk. The capacitance of the space in the throat 20 or 20' varies sufficiently when milk pulses through to be detectable and hence gives an indication of milk flow. It is desirable that the direction of milk flow should be upwards to avoid the registering of trickles of milk which are not single well-formed pulses. An electric circuit converts pulsed variations in the capacitance into a corresponding pulse signal and actuates a solenoid valve to control vacuum. The signal pulses are also connected to a device which gives an indication of the total milk obtained from the cow.

In the spring-released hydraulically actuated friction clutch disposed within a hollow gear rim 1 described in Specification 1,091,054 comprising a pair of V-grooved axially slidable discs, splined to a shaft, hydraulically moved apart into engagement with corresponding V-grooved plates secured each side of the gear rim, in which the co-operating clutch discs and plates are of materials having the same coefficients of thermal expansion and one or both plates of each pair having a metallic surface coating, the metallic coating has non-metallic particles embedded therein influencing the frictional behaviour. Finely divided silicon carbide embedded in the metallic surface coating provides a high coefficient of friction, and the addition of quartz powder in the coating additionally maintains the coefficient of friction at very high temperatures whilst the addition of aluminium silicates also increases the friction coefficient without substantially increasing abrasion of the surface coating. In addition to the friction increasing substances above and others such as asbestos fibres, lubricating substances such as graphite and molybdenum disulphide may be added, the coatings being sintered, cast or sprayed on the clutch members.

An induction machine 6, having stator 1 and rotor 2, is coupled mechanically, directly or indirectly, with a further machine 7 having stator 3 and rotor 4 the rotor windings being interconnected through diodes 9 and controlled rectifiers 8. The firing circuit 12 for the controlled rectifiers is supplied from the A.C. source 13 through a phase shifter 14 and an induction machine 15 having stator 16 and rotor 17, the rotors 4 and 17 being inter-coupled. The rotating fields provided by the stators 1 and 3 may be oppositely directed, the machine 6 operating as a motor and power being transferred from the rotor 2 to the rotor 4 which adds to the mechanical power. The speed of the combination is controlled by the phase shifter 14. In a modification the phase shifter 14 is connected between the rotor 17 and the firing circuit 12, the fields due to the stators I and 3 rotating in the same direction. The respective stator and rotor windings may be accommodated in common cores, the stator windings having different pole members to prevent mutual interference. The rotor windings may be interconnected through two groups of controlled rectifiers which are oppositely disposed between two three-phase bus-bars to control the power from the rotor 2 to the rotor 4. In another embodiment, the stators 1, 3, 16, form one unit whilst the rotors 2, 4, 17 form another unit, or, alternatively, the parts 16, 17 may be separated from the others.

The phase shifter 14 may be connected to the rotor 4, and the rotors 2, 4, frictionally intercoupled through wheels engaging a rail. The machines may be operated as generators, the rotor 2 being driven by a prime mover above synchronous speed. The exciting current for the stator 1 can be supplied from the stator 3. Direct-current energy is stored in a capacitor between the rotors 2 and 4.
