Title: Castine blooms
IPC: B22D7/00
Filed: 1979-07-30
Abstract: A bloom 6 is made by bottom casting in a mould 4 and during pouring and solidification of the bloom the upper face of the bloom is covered with an exothermic or insulating medium which slows down or prevents the cooling of the upper face so that cooling and solidification of the bloom proceeds from the bottom upwards. The ratio   <IMAGE> is equal to at most 1.3 and for a bloom for producing a flat forging the ratio H DIVIDED D  is preferably at most 0.8 while for a bloom for producing a hollow forging the ratio H DIVIDED D  is preferably at most 1.2. The bloom may be compressed, drilled to remove segregation from the centre, and forged to produce a hollow article. <IMAGE>
Patent GB-2056916-A (GB)
Title: Apparatus for composing text in arabic
IPC: G06F17/27
Filed: 1979-08-21
Abstract: The invention may be employed in photo-type-setting machines and typewriters to reduce the number of keys needed to cater for starting, middle, end and isolated forms of Arabic letters. The letters are keyed in as commands which are independent of the position of each letter in the words of the text. A control unit makes a number of different character commands correspond with each letter command and is arranged to select one of the character commands associated with each letter command as a function of whether the preceding command is or is not a space command or a semi-joined letter with only an isolated/starting form and an end/middle form. Normal letters can be decomposed into start and middle forms and a terminating part which, added to the middle and start forms yields the end and isolated forms respectively. A letter key 31 commands a start form (element 33) in the reset state N of a relay 37A common to all keys and also sets the relay. When the relay is set, operation of a key 31 commands the middle form (element 34). The last letter keyed in is always stored in a memory 36. Operation of the space key 32 causes the terminating part (plus space) of the stored character to be printed (element 35). <IMAGE>

Title: Method and apparatus for recharging dry batteries
IPC: H01M10/44
Filed: 1979-04-12
Abstract: A method and an apparatus for recharging dry batteries, whereby the dry batteries (4) are charged with one of the periods (7) of an intermittently pulsating alternate current, whereas the batteries (4) are allowed to discharge somewhat during the periods between the charging pulses (7). The charging current is balanced according to the charge condition of the batteries so that the batteries irrespectively of the charge condition are charged with as constant average current as possible with possible variations depending on the sensitivity of the charging components to temperature or current strength. The apparatus comprises a transformer for stepping down net current to suitable charging voltage, a diode (D1) for letting through intermittent charging pulses, a resistor (R1) connected parallelly over the diode (D1), terminals for one or several dry batteries between the diode (D1) and the resistor (R1) on one hand and a second pole terminal (2) on the other hand. Parallelly over the dry batteries (4) are connected a Zener-diode (D1) and in series therewith a PTC-resistor (R3), whereby the PTC-resistor (R3) is designed so as to balance the average charging current over the dry batteries (4) to be maintained as constant as possible.

Title: Lock system for storage units
IPC: G07C9/00
Filed: 1980-07-08
Abstract: The present invention relates to locker system (10) comprising a set of lockers (11) which are centrally controlled by a computer. According to the invention the computer upon payment of a prescribed fee chooses a free locker which is indicated to the user and can then be opened by pushing the corresponding button (12).

Patent GB-2094875-A (GB)
Title: Self-release mechanism
IPC: F16B21/07
Filed: 1981-03-11
Abstract: A self-release mechanism in which a first part 1 includes a spindle 5 having heads 7 and 7a receivable in tapered recesses 17 in respective flap- like seats 8 and 8a. The heads are normally retained by lugs 21 and 21a, the engagement of the heads and the lugs preventing opening of the flap- like seats 8 and 8a. Rotation of the part 1 for a sufficient angular movement brings cut-away parts 16 and 16a on the heads into alignment with the ridged 21 and 21a of the lugs whereby the parts 1 and 2 are released. The mechanism is intended for releasable fuel tanks on aircraft; in this case gravity pulls part 1 away from 2, the tapered heads 7, 7a cramming the flaps 8, 8a apart. In an alternative embodiment (Fig. 6), heads 7, 7a are not positively held in the seats; instead the mutual parting of seats 8, 8a is prevented by the engagement of lug 63 on spindle 5 with extensions 61. Rotation of the spindle releases the engagement and so part 1. <IMAGE>

Abstract: A coin-freed traffic barrier, e.g. for car parks, comprises a fixed step- like obstruction (1) able to resist or prohibit the advance of a vehicle, a hinged ramp platform (8) disposed in advance of the step-like obstruction and rockable between a lowered position and a raised position, in which its trailing edge (11) is adjacent the top of the step-like obstruction, spring means (12) urging the platform into its raised position, latch means (15) operable to lock the platform in its raised position to permit a vehicle to advance over the step-like obstruction, and control means including a coin-operated device or the like, for controlling the operation of the latch means. The latch means (15) is normally retained in its latched condition, and the control means is responsive to the front wheels of a vehicle approaching the platform (8) to release the latch means if the driver of that vehicle does not insert the prescribed parking fee in the coin- operated device. The barrier step (1) has an exit ramp unit (3). The barrier is provided with signal lights (37, 40), a swing- out indicator arm (44), and an acoustic warning device. <IMAGE>

Title: Movement for an electronic watch with analogue display
IPC: G04B33/10
Filed: 1981-04-22
Abstract: In the movement for an electronic watch with analogue display, hand-carrying arbors 20, 22 have pinions 20a, 22a of very small diameter, rather than wheels. The cell 10 has a diameter which is substantially equal to the radius of the movement plate 2, since the cell extends from the periphery of the movement up to the pinions 20a, 22a. The wheels 28, 30, 34, 40, 42 which drivably connect the motor 8 to the pinions 20a, 22a are arranged in such a manner that there is no overlapping between the cell 10 and the wheels. This makes possible a movement which is both of small diameter and thin.
