Title: Elevator control system
Inventor: HORNUNG STEPHEN ANTHONY
IPC: B66B1/46
Filed: 1962-02-09
Abstract: 937,896. Lift control systems. OTIS ELEVATOR CO. Feb. 9, 1962, No. 5085/62. Drawings to Specification. Class 78 (3). A lift control system is provided with means for registering landing calls, means for cancelling the call at a landing as the car stops there in response to the call and means for detecting the number of unanswered calls. The system is described as applied to the lift control system described in Specification 721,988 wherein three lift cars operate in any one of four predetermined programmes, i.e. a light traffic, an up-peak, a down-peak or an updown programme. The landing call buttons comprise cold cathode tubes which conduct and remain conducting when touched by the intending passenger thereby causing an increase in the current flow of the system. This increase produces a pulse which steps-on either an up or down bi-directional stepping switch and which also steps.on a bi-directional stepping switch which counts the total number of unanswered calls. When means are initiated to slow down and stop a car at a floor with a landing call, a decrease in the current flow produces a pulse of opposite polarity which steps back the stepping switches. The programme is selected automatically in accordance with the total of unanswered up and down calls. In a modification, calls are detected and counted, and car call registering and cancelling circuits similar to the corresponding landing call circuits are provided. The information provided by the call counting system can be used for various control functions, such as removing cars from group operation, or varying the interval which must expire between the despatching of successive cars.

Filed: 1917-04-12
Abstract: 111,619. Hall, B. J. April 12, 1917. Printing processes; printing in several colours; printing-surfaces.-Plans, drawings, or the like are copied in colours by gelatinous copying-composition by combining the two known processes of inking-up and the aniline die or hektographic process. A suitable composition such as 20 parts of gelatine, 60 parts of water, and 1 part of ferrous sulphate, is prepared with parts of the plan or design such as the outlines by a special ink or by a blue print as in the well known " Ordoverax " process or any other known process, so that it may be inked up with printers' ink in these parts. It is also prepared on other parts that are to be coloured with aniline dies in one or more colours. This may be done by transfer from a blue print itself coloured with aniline colours in the required parts, or by other suitable means. In printing, the surface is inked up, the ink adhering only to the prepared outlines &c., so that the prints receive this ink and also the aniline colours at the same impression.

Title: Improvements in or relating to systems for the protection of electrically propelled vehicles running on tracks
IPC: B61L3/14
Filed: 1943-04-02
Abstract: 566,033. Safety systems for electrically propelled track vehicles. NORTHERN ALUMINIUM CO., Ltd., and SIMON, V. April 2, 1943, No. 5308. [Class 105] In a system in which electrically-propelled track vehicles, for example cranes, are prevented from collision with one another or with end blocks by a relay 7 on the vehicle, cutting off the propulsion current when a vehicle enters an occupied or an end section, the sections being defined by a pair of interrupted conductors 2 arranged alongside the track with the interruptions 3 staggered in the two conductors and the relay being connected to one of the power supply conductors 1 at the intake side of the main switch 8 on the vehicle and to the pair of interrupted conductors 2 by means of contact shoes with the relays on alternate vehicles connected to power conductors of different polarity, there is provided means by which the driver can render the control function of the relay inoperative. It will be seen that if a vehicle enters an occupied section then the relays 7 on the two vehicles will be energized over a circuit from the +ve. supply conductor through a fuse 9, relay 7, contact shoes on one vehicle, to section conductor 2 and thence through contact shoes, relay 7 and fuse 9 on the other vehicle in the section to the - ve. supply conductor, whereby the relays 7 open their contacts 5 to cut off the propulsion current from the motors 6. The operators may, however, render the control ineffective by holding down a push-button 10 to effect a supply of propulsion current. At the end half-sections 4a, a connection is made to the - ve. supply conductor through a resistance 11 so that these half-sections act as occupied sections ; in the case of a 3-wire D.C. supply or a polyphase supply, this connection may be made direct to the neutral wire. The relays may be potentiometer-connected across resistances.
