Title: Crane crab transfer device for travelling gantries - raises one gantry end into line with other and locks during transfer
IPC: B66C7/14
Filed: 1973-03-26
Abstract: One of the travelling gantry beams has its end nearest the other one raised on its track, and it pivots at its other end, allowing it to be brought exactly into line with the other beam for the crab to be transferred from one to the other. Typically, this movement can be effected by a jack, stopped when two contacts on the beams meet. Travel of the crab along the beams can be restricted by stops at the ends, which are only retracted when the two beams are locked in line by a plunger extending into aligned bores in the beam ends.

Title: Replacement of suspension bridge cables - involves attaching deck support rods to new cable suspended over old cable
IPC: E01D22/00
Filed: 1973-04-09
Abstract: The method has the advantage that is rapidly carried out and that traffic can continue to use the bridge while work proceeds. The method avoids the use of a temporary cable and also avoids putting any extra load on the old cable. The method consists of suspending the new full or partial cable above the existing one. The loads are then progressively transferred from the old cable to the new one. This is done by releasing the deck support rods and then clamping them on the new cable.

Title: Method of producing door frame members - entails press cutting of notches followed by folding and welding
IPC: E06B3/96
Filed: 1974-02-05
Abstract: The method involves dividing a straight member into two posts and a head beam using the press (2), the cutting notches (5) at proposed corner locations to be followed by the folding of the member into a frame, the mitred corner joints then being welded.

Title: Viscose filament spinning process - uses a simplified drying phase and carbon disulphide extraction to shorten process
IPC: D01F13/02
Filed: 1974-10-29
Abstract: A process is claimed for the manufacture of viscose filaments, where the viscose solution is continuously passed through a spinarette followed by final reduction and washing and brightening and drying, the filaments being cooled during the final reduction phase to a temp. below the evapn. point of the carbon disulphide, the cooled filaments being then washed and brightened. In the drying phase the temp. is controlled to give a simultaneous extn. of the residual moisture and the carbon disulphide from the filaments. The simplification of the drying phase and the extn. of the carbon disulphide shortens the filament manufacturing process and removes one manufacturing stage from conventional processes.

Title: Heating and ventilation regulator for animal breeding house - uses probe situated in animal housing to control switching of heater and continuous variation of ventilator
IPC: G05D23/24
Filed: 1975-12-10
Abstract: The circuit controls the operating time of a heating system functioning at a working level and rest level, and the ventilation level gradually between a minimum value and a maximum value, whilst processing the signals delivered by a sensor. the signals from the sensor are converted into variation of electrical resistance which are converted into voltage variations by means of two resistance bridge networks. each of these networks delivers respectively a first and a second voltage to a first and second comparator circuit. The first comparator circuit feeds a step circuit which delivers an output signal to a relay when its input single exceeds a first step. The output signal stops when the input signal is less than a second step lower than the first. The relay controls the work or rest level of the heating system. the second comparator circuit controls a rectangular pulse generator operating at a frequency which is twice that of the electrical supply. The pulses control a triac mounted in the motor supply circuit of a ventilator. the width of each pulse is a function of the output signal of the second comparator circuit.

Title: Coherent data transfer system for computer memories - is between hierarchy levels with various transfer speeds and uses test and set operating system
Inventor: RECOQUE ALICE MARIA
IPC: G06F12/0811
Filed: 1976-03-10
Abstract: The coherent data transfer system relates to a sequence of hierarchical levels, typically a fast level (i) an intermediate level (i+1) and a slow level (i+2). In the example given, the intermediate level is associated with a storage unit Bj, address assembly lines (AB) and data assembly lines (DB). The operating system (TS) is a type known as "Test and Set". Each TS operation activates a processor and transfers global information to the fastest available level. A marking system is included to signify whether the data is modifyable or not. A repertoire is available to decode and modify selected words. During the modification process data may be transferred into and out of the slower levels several times.

Title: Switching circuit dependent upon rotational speed - pulses representing speed fed to converter and monoflop followed by relay
IPC: G01P1/10
Filed: 1976-04-22
Abstract: The monoflop generates constant width pulses and an output stage has a switch, esp. a relay, which operates at a certain number of pulses per unit time. A NO circuit (7), following the monoflop (6) output is connected to the output stage (8) directly and through a second monoflop (9). The output stage (8) has means which operate the switch (13) when spacing between the first monoflop's (6) pulses is smaller than the width of the pulses generated by the second monoflop (9). This circuit can also be used as a non-working switch since it reliably functions at less than 30 r.p.m.
