Title: Thunderstorm warning system
IPC: G06Q50/28
Filed: 1969-03-17
Abstract: In a system for detecting the proximity and violence of a thunderstorm, an alert warning is provided when the storm is some distance away, and an alarm warning when it is closer. The alert warning is given if the electric field at the detector system rises above a predetermined lower threshold value or if occasional pulses or pulse trains of r. f. radiation in excess of a predetermined energy are received, while the alarm warning is given in any of the circumstances a) the pulse or pulse trains recur within a predetermined time b) the pulse or pulse train occurs simultaneously with a detected pulse of optical radiation exceeding a predetermined threshold or with an electric field exceeding the lower threshold c) the electric field intensity exceeds the higher threshold. An A. C. signal from an electric field detector 7 (see below) in a detector unit 1 is passed via a cable to two threshold discriminators 8, 9 in a logic unit 2. Any signal from the lower threshold discriminator 8 is passed both to an alerting system 3 and to an OR gate 10. Any signal from the high threshold discriminator 9 is passed to an alarm system 4. R. f. radiation from the thunderstorm is detected at 11 and passed to a threshold discriminator 12. Any output from this is passed to an AND gate 13 to which the output from the OR gate 10 is applied and also to a delay circuit 14. The output from this is passed to the alerting circuit 3 and to the other input of the OR gate 10. The delay circuit is such as to provide an extended pulse after a given interval. Thus the AND circuit will pass a signal if an r. f. signal appears when the electric field is above the lower threshold or if two r. f. signals appear within a given time of one another. The output of the AND circuit is applied to the alarm system 4. An optical radiation detector, responding to lightning flashes in excess of a given intensity may be associated with the system. Optical radiation is detected at 17 Fig. 2 (not shown) and the signal applied to the discriminator 19, whose output is applied to AND gate 20. The r. f. pulse is also applied to this gate, whose output is also applied to the alarm system 4. Electric field detector: This consists of a metal plate 26 within a screened box 21 having a cover with apertures 25. A shutter 24 is rotated to open and close the apertures to the electric field in the vicinity by a motor 23 within the box. An A. C. signal is induced on the plate 26 in accordance with the field intensity and transmitted via a feeder 22 to the logic unit. The detector unit and logic unit are independently earthed.

Title: Top block shifting mechanism for mould apparatus
IPC: B22D18/04
Filed: 1969-05-21
Abstract: A bottom pour slab-casting mould has two side blocks 12 which can be moved towards and away from each other, and a plurality of inner blocks 14, 16, 18, 20, defining with the side blocks, a mould cavity 12, a runner 25 and a riser 22. The top inner block 14 and its riserdefining extension 15 are so mounted that they may be moved vertically and longitudinally of the side blocks to free a slab cast in the mould. Two platforms 28, 30 (Fig. 2) are attached to one of the side walls 12 and have mounted upon them a platform 32 which accommodates two vertically acting jacks 38 powered by a motor 44 through gearing 34, 36, 40, 42, 46. The jacks, operating in a 1 to 1 ratio, raise and lower the block 14 via links 48, adjustable blocks 68 and a mould block support 49. Each link 48 has two parts 52, 70 connected by a toggle linkage (not shown), both of these parts being pivoted to the blocks 68 but only parts 52 being pivoted to the jacks 38. As the jacks are raised, the wheels 80 mounted on the parts 70 engage the undersides 124 of the platform 32 and force the mould block support 49 to the right, this in turn freeing the riser extension 15 from the cast riser in the mould. The links 48 are sprung so that on lowering of the jacks 38 the links and mould parts return to their original positions.

Title: Continuous process for preparing derivatives of benzene with fluorinated side chains from the corresponding chlorine compounds
IPC: G03F7/038
Filed: 1974-11-04
Abstract: Preparation of derivatives of benzene containing CF3 groups from the corresponding compounds containing CCl3 groups (e.g. trichloromethyl benzene) is carried out continuously with excellent yield rates by reaction with liquid hydrogen fluoride in an autoclave above 80 DEG C, (which latter exceeds the stoichiometric proportion by at least 25 mole %). The reactants are fed continuously into the autoclave. The reaction mixture preferably becomes pressurized to at least 20 atmospheres and homogeneous after having reached a certain filling level. The reaction mixture is thereafter withdrawn proportionally to its feeding-in rate. The mixture may be conveyed through one or several additional autoclaves with the final withdrawal of the reaction mixture being out from the terminal autoclave of this cascade. The fluorination products are well known starting and inermediate products for the preparation of dyestuffs and pesticidal compositions.

Title: Marker for telecommunication system
IPC: H04Q3/54
Filed: 1976-02-05
Abstract: A marker controlling the establishment of connections between local subscriber lines and inter-office links, via an associated line concentrator/distributor, comprises a link allocator, a signalization unit and a service unit. The link allocator responds to requests from a local subscriber line, transmitted via a line finder, or from a remote exchange, arriving over a common signal path, to control the line concentrator/distributor for connecting that local line to an available link or a designated link to a selected line. The signalization unit coacts with a respective two-way coupler in each link, in a time-division mode, to pick up outgoing dial pulses for transmission via the common path and to transmit switching instructions from that path to the engaged subscriber line. The service unit, communicating with both the link allocator and the signalization unit, receives and sends out information relating to possible malfunctions or alarm conditions.

Title: Opening roller for an open-end spinning machine
IPC: D01H4/32
Filed: 1977-04-06
Abstract: An opening roller for an open-end spinning machine carries an array of pins on its external surface. The pins are arranged in repeating patterns, each pattern comprising from 7 to 12 axially extending rows of equally-spaced pins, the relative dispositions of the pins in adjacent rows being such that the pins lie on lines parallel to a helix which passes through points in the first lines of two adjacent patterns, which points are axially off-set by three times the axial spacing of the pins in 7- or 8-row patterns, four times the axial spacing of the pins in 9- or 10-row patterns or five times the axial spacing of the pins in 11- or 12-row patterns. This arrangement reduces the risk of entanglement of fibres combed by one pin with fibres combed by an adjacent pin in the next row and reduces the tendency of the pins to direct fibres axially along the roller. An open-end spinning machine incorporating the roller is also disclosed.

Title: Articulated robot assembly
IPC: A63H33/00
Filed: 1977-06-08
Abstract: An articulated doll figure, such as a robot, having removable appendages and capable of locomotion is provided. The robot figure is particularly adaptable to be separated into subcomponents to form individually or in conjunction with accessory items, independent toys. In this regard, a body or trunk member having an electrical motor is connected to appropriate power transmissions to provide rotational couplings on at least four separate positions on the trunk member plus directly driving an endless track drive pivotally mounted on the back of the trunk member. A lower torso portion can support another transmission assembly to provide sequential linear displacement motion in either branch of the legs. Lower leg members like the lower torso, are removable and each includes a roller assembly capable of coacting with a clutching member to provide unidirectional rotation. Each lower leg member can be mounted for connection with the torso transmission means to provide a walking motion for the robot. Alternatively, the lower leg member subcomponents can be divided to form independent vehicles. A storage cavity in the trunk member can support a smaller doll member for mounting on the subassemblies. The trunk member, itself, can operate independently as a subassembly with locomotion provided by the endless track drive. Each of the parts are dimensionally designed to coact with not only other parts of the robot figure, but other complimentary toy assemblies to further form independent sub-toy assemblies.
