Patent GB-134822-A (GB)
Title: Device for Testing the Sensitiveness of the Wrist.
Filed: 1919-09-30
Abstract: 134,822. Riebe-Kugellager-und Werk- zeugfabrik Ges. Nov. 7, 1918, [Conven- tion date]. Testing physiological functions.-In order to test a workman's capacity for working a milling- machine, he is set to turn a screw against an in- creasing pressure to a predetermined extent. The parts are then brought back to their original posi- tion and he is required again to turn the screw an amount equal to that of the first test. The screw, which is hollow, is seen at 9, working in a nut 3. It is driven by the crank-handle 1, the spindle 2 of which passes through the screw and can be clutched to it by the clutch 10. The nut 3 is prevented from turning by the bar 5, which slides through the standard 14, and operates a pointer 6 moving over a scale 7. A helical spring 4 surrounds the screw 9 and fits between the nut 3 and standard 14. As the screw advances, it compresses the spring, and the corresponding pressure is shown on the scale 7. After the nut has been advanced to a predetermined extent, the clutch 10 is opened, and the parts brought back to zero. The clutch having been once more put into action, the examinee is required to bring the parts into the position of the first test. In order to prevent the first test from being any guide in the second, the nut may be adjustable independently of the crank, or the abutment against which the spring 4 bears may be adjust- able, so that the initial tension of the spring is different; or the setting of the crank may be altered in other ways than by a clutch.

Title: Improvements in or relating to Lifting Beams for Overhead Travelling Cranes
Inventor: MAKOSINSKI STANISLAW
IPC: B66C1/10
Filed: 1967-05-24
Abstract: 1,152,280. Adjustable lifting beams. WELLMAN MACHINES Ltd. 3 May, 1968 [24 May, 1967], No.2407.3.167. Heading B8H. A pair of lifting hooks 12, for suspending a ladle, are pivoted to a beam 11 by pins 24 which rest in inverted V-shaped slots 13. To move the pins 24 from the end 18 of the slot to the end 19, so that a different size of ladle may be handled, the beam is lowered until the lower ends of the hooks 12 rest on the ground. Further lowering causes the pin 24 to rise, abut a latch 36 and raise it to the chaindotted position shown. When the pin 24 has risen above the apex 23 of the slot 13 and the apex 33 of a rocker plate 27 the beam is raised so that the pin begins to descend down the opposite side of the slot 13. As it does so. it trips a latch 37 and tilts the rolker-plate to the right when the pin abuts a trip arm 35. The latch 36 now engages the end 44 of the latch 27 and the mechanism is thus re-set with the pin at the opposite end of the slot 13. Repeating the raising and lowering procedure moves the pin back again. In practice, both ends of the pins 24 are supported in slots 13.

Abstract: 1401664 Ophthalmoscopes; prisms; light guides H CARDONA 24 May 1972 [23 May 1972] 24310/72 Heading G2J Ophthalmoscopes for observing the fundus of an eye have a system of reflecting surfaces for providing an image of the fundus which lies on a line of sight coincident with the line of the image emerging from the eye, the image being erect and unreversed, appearing to the observer as it would if he were observing from a point within the eye behind the lens of the eye. As shown in Fig. 6, the image is corrected by a compound prism 218. This compound prism is formed from a first, base prism 222 which is triangular in cross-section perpendicular to the line of sight, a second prism 224, quadrangular in cross-section perpendicular to the line of sight, and a roof prism 226. The image is reflected at surface 228 of second prism 224, to surface 230, to surface 232, to surface 234, to roof surface 236 and thence to the observer. The illumination is by light-conducting fibres. The illuminating light guide has a condenser at the end thereof, and filters 214 or reticles 212 may be arranged adjacent the end. The illuminating light is reflected by a semi-reflector 208 through objective 206 to the eye. Objective 206 preferably, as shown has its optical axis at an acute angle to the line of sight to prevent reflections from its surfaces degrading the clarity of the image, and, also for this reason, absorber 240, again at an acute angle S to the direction of the line of sight is provided to remove illuminating light which passes semi-reflector 208. The ophthalmoscope is formed with a casing which can be hand-held, providing a handle part. Optional or additional eye-pieces may be added, and these may be monocular or binocular. Provision may also be made for attachment of a still or movie camera.

Title: Improvements in or relating to gas discharge tube circuit arrangements for generating an impulse pattern or patterns
Inventor: DAVISON ALAN
IPC: H04M19/02
Filed: 1951-10-19
Abstract: 711,507. Automatic exchange equipment. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Sept. 29, 1952 [Oct. 19, 1951], No. 24407/51. Class 40 (4) [Also in Group XL (c)]  A pulse pattern generator comprising a gas tube counter is arranged to interrupt the supply of current from an oscillator and thus to provide ringing current, supervisory tones or meter pulses in an automatic telephone exchange. The Figure shows a circuit for generating a pulse pattern used for the automatic routine testing of automatic telephone exchange equipment. Cold-cathode gas-discharge tubes CC1-CC10 are connected in a ring counter circuit under the control of 120 cycles/second pulses from multivibrator MV which are first amplified in valve V3 and applied in common to the striker electrodes of the tubes CC1 CC10. When battery is applied to the circuit, gas tube CC13 conducts to apply a positive pulse via rectifier MR1 to tube CC1 which fires, the counter then being controlled by multivibrator MV, the voltage drop across anode resistor R9 when a tube fires extinguishing any other tube which was formerly conducting. Thus the pattern of conductivity progresses round the counter chain under the control of multivibrator MV, the tubes CC1-CC10 being connected to the gas-filled diodes CT1-CT8 and CT9-CT13, so that if a given tube in the counter chain is conducting the associated diode or diodes CT1-GT13 will also fire and will also extinguish when the associated counter tube is extinguished. When a diode CT1- CT8 is conducting a positive pulse is applied to the control grid of the normally non-conducting valve V4 to cause it to conduct and operate relay A. Similarly the firing of a diode CT9- CT13 operates relay B. Relays A and B will therefore operate and release with a make/break ratio of 4/1 and 1/1 respectively in a continuous cycle of 12 impulses/second. Relays A and B control the associated contacts A1, B1 which are connected to the automatic routine testing equipment (not shown). The second windings of the polarized relays are connected in series with non-linear resistors NLR1, 2 to compensate for variations in the battery voltage, which is also stabilized by gas tubes CC11 and CC12. The counting chain may be prevented from operating by operating key K1 when tube CC1 is maintained conducting. To enable the counting chain to stop with any given tube CC1-CC10 conducting a 3-way switch may be provided which (a) connects the pulse source to the counting chain, (b) disconnects the pulse source, and (c) connects the common trigger electrode circuit to a high voltage source. The circuit may be used to control the supply of ringing current, supervisory tones and metering pulses by alteration of the frequency of multivibrator MV and of the number of tubes in the counting chain. The relays A and B are used to control the supply of current from an oscillator to give the tone of the required frequency with the requisite interruptions.

Abstract: 788,015. Protective cut-out arrangements- MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 22, 1956 [Aug. 30, 1955], No. 24906/55. Class 38 (5). To protect a section of a power line, radio means at each end of the section transmit a frequency modulated carrier wave modulated in dependence upon the phase conditions at the associated end and having a carrier frequency different from that transmitted from the other end, the equipment at each end including means for mixing the received and transmitted modulated carrier waves, the resultant of the mixing being used to prevent tripping of the section circuit-breakers under external fault conditions. Fig. 1 shows the equipment at one end of the protected section, the equipment including low-set relays 18 . . . 20 and high-set relays 15 ... 17. In the event of a fault one or more of the relays 18 ... 20 closes contacts to complete a circuit for the transmitter and one or more of the relays 15 ... 17 closes contacts to energize a timed relay 9. At the same time a voltage component produced by a summation current transformer 27 and non-linear resistor 28 is applied to a limiter circuit including diodes 29, the output of which is applied to a modulator valve 30 to modulate the frequency of a crystal-controlled oscillator 31. The frequency modulated output of 31 is frequency multiplied at 33, amplified at 34 and fed through a transformer 35 to a directional aerial 36. This aerial is also used for reception and feeds through a coaxial line filter 37 and amplifier 38 to a mixer 39 which is also fed through condenser 40 from the output circuit of the transformer 35. The output of the mixer 39 is of intermediate frequency with a frequency deviation dependent on the phase relationship of the summation transformer outputs at the two ends and is amplified at 41 before being fed to a linear detector circuit. The output of this circuit is of line frequency and of an amplitude dependent on the phase relationship. If the fault is external, the output of the detector circuit is sufficient to energize a relay 11 which opens its contacts 10 before the contacts 8 of the timed relay 9 can close and so prevents the energization of the associated circuit-breaker trip coil 7. Fig. 2 (not shown) illustrates a modification in which a resistive network takes the place of the summation transformer.
