Title: Apparatus for telemetering and integrating impulses from a number of measuring stations in a central recording station
IPC: G08C25/02
Filed: 1955-06-21
Abstract: 815,903. Electric signalling systems. LANDIS & GYR A.G. June 21, 1955 [June 23, 1954], No. 17967/55. Class 40 (1). [Also in Group XIX] Telemetering apparatus wherein the readings of a group of meters are transmitted as trains of impulses to a central station wherein they are recorded and registered on individual counters and on a grand total counter. At each meter station impulses generated by an impulse contact ZJ, Fig. 1, of the meter are registered on one or other of two storage devices SPI, SPII in accordance with the position of a switch device SU. Each of the storage devices comprises rotary selector switches and associated relays. At the central station a selecting device MW comprising time-controlled rotary switches successively connects each meter station via an ultra-short-wave channel to the central station whereupon the switch device SU is changed over to connect the impulse contact ZJ with the other storage device SPI or SPII and the storage device SPII or SPI previously connected thereto is now connected to the transmitting arrangement UK. The registration on the lastmentioned storage device is scanned by a rotary selector switch which transmits the said registration as a series of impulses to the central station wherein they are received and registered by a rotary switch and associated relays. A number of impulses indicative of the particular station is also transmitted to and registered in the central station. The central station registering means are then scanned and the appropriate number of impulses are re-transmitted to the meter station wherein they are received by a rotary selector switch and compared with the original number registered at the meter station. If the two numbers are in agreement an impulse is sent to the central station and the number registered therein is transmitted by a rotary switch to a recording counter ZD, to the appropriate one of a group of totalizing counters SZ1-SZX and to a grand total counter GSZ. At the same time in the meter station the registered number is transmitted to a recording counter ZD and a total counter SZ1. The recording counters ZD effect recording and are zeroized. The time of the recording is also recorded. If the above-mentioned comparison results in lack of agreement an alarm impulse is sent to the central station and the number registered therein is cancelled and the number registered at the meter station is again transmitted, If the comparison now results in agreement the number is recorded and registered at the central and meter stations as before. If there is lack of agreement for the second time the respective registrations at the central and meter stations are recorded and totalled, a special mark being made beside the central station recording.

Patent GB-990784-A (GB)
Title: Improvements in or relating to balls
Inventor: FORD PETER
IPC: B29C33/12
Filed: 1960-05-23
Abstract: A process for manufacturing balls, particularly golf balls, comprises the steps of firstly coating a core with an integral, unpatterned cover of a partially cured but still thermoplastic polyurethane polymer and subsequently moulding the covered core into a patterned ball whilst simultaneously advancing the cure of the polyurethane polymer to a non-thermoplastic state.  The core may comprise vulcanized rubber or polyurethane thread windings and is advantageously sealed by dipping into prevulcanized rubber latex prior to applying the cover thereto.  The polyurethane coating may be applied to the core either by injection moulding or by feeding a polyurethane pre-polymer syrup on to the surface of the core whilst continuously rotating the latter and partially curing the polyurethane by heating or reaction at room temperature.  The curing process is then interrupted, for example by cooling, the core is transferred to a patterned ball mould, and the assembly heated to complete the curing of the polyurethane. The curing is preferably effected by means of a cross-linking agent mixed with the polyurethane polymer, and the mixture may also contain mineral oils, fillers and colouring materials. Specifications 990,785 and 990,786 are referred to.

Title: Improvements in or relating to typographical composing and casting machines
IPC: B41B11/18
Filed: 1953-07-03
Abstract: 725,490. Type-bar-making machines. MERGENTHALER LINOTYPE CO. July 3, 1953 [July 25, 1952], No. 18528/53. Class 100 (3). Assembling and clamping matrices ; counting - apparatus.- In a typographical line-casting machine having an assembler slide, an adjustable assembler slide stop, and a stop contact member to co-operate with the stop and limit movement of the slide, there is provided means for setting the stop according to line length over a range of adjustment less than the desired range of movement limitation of the slide, and means actuated by the slide for moving the stop contact member at a correspondingly lower speed than that of the slide. The stop 14, Figs. 1 and 2, is adjusted by a threaded rod 16 rotated by a hand-wheel 22, a pointer 19 on the stop-carrying block 15 co-operating with an em-scale 20. The left-hand vise jaw 6 is adjusted by a threaded rod 11 also rotated by the wheel 22 at twice the speed of the rod 16. The stop 14 thus moves through half the distance of the jaw, but the scale 20 indicates the actual adjustment of the jaw and therefore of the line length. The stop contact member 26 is carried on a supplemental slide 30 in a groove 30a in the assembler slide 4 and carries a rotatable pinion 33 meshing with a rack 34 on the slide 4 and a stationary rack 35, so that the member 26 moves at half the speed of the slide 4 so as to allow the slide 4 to move through the same distance as the jaw. To allow adjustment of the slide 4 further to the left for correction of a tight line, the rack 35 can be released by tripping a latch 36. A rod 40 within the member 26 contacts the stop 14 four ems before the line is complete, and operates a pointer 41 moving over two scales to indicate the line deficiency and the number of spacebands needed for justification. In another form, Fig. 9, a second pointer 50 moves over one of the scales to indicate the number of spacebands in a line. As each spaceband leaves the magazine, a switch is closed and opened to energize momentarily a solenoid 57, which acts on an arm 54 carrying a pawl 55 so as to move a segmental ratchet 53 through one step. The ratchet is secured to a shaft 52 carrying the pointer 50.
