IPC: B43K25/02
Filed: 1929-05-07
Abstract: 334,570. Vivian, G. S., and Valentine &. Sons, Ltd. May 7, 1929. Pockets, retaining pens and pencils in- - The cap or other part of a fountain pen or the like and the clip or the like by which the pen &c. is retained in a pocket are constructed with cooperating parts so that while endwise movement of the clip is prevented the position of the clip may be positively adjusted endwise on the cap. In one form, shown in Fig. 1, the cap 2 is of the kind having an internal sleeve, 3 adapted to rest on the top 4 of the pen 1 to prevent leakage of ink, and is provided with a series of annular grooves 6 into any one of which may be placed a semi-circular or forked extension 13 of the clip 12. The position of the clip 12 may be changed by unscrewing the sleeve 3, the top 9 being knurled or serrated for this purpose, and removing it together with the clip which passes up a slotted part 10 of the cap 2. In another form shown in Fig. 4, a reduced portion 14 of the cap 2 or of a sleeve 3, where such is provided, carries a number of collars 15 between any pair of which an annular extension 16 on the clip 12 may be clamped by a screw top 9a of the cap 2. The collars 15 may be of the same material as the cap and may have rings or washers similar to the ring 16 fitted between them.

Abstract: 1,267,802. Aerials. POST OFFICE. 24 March, 1969 [25 March, 1968], No. 14357/68. Heading H4A. A dielectric lens assembly comprises a waveguide coupling portion consisting of a cylindrical part 1 with a tapered part extending from one end, and a lens portion 3 extending from the other end of said cylindrical part. The lens portion has a face which is outwardly dome-shaped, and it has an axial thickness of not less than 2d<SP>2</SP>/# e , where d = diameter of the cylindrical part 1 and # e  = wavelength in the dielectric material of the lens portion 3 at the midband operating frequency. As described, the lens assembly is made of polythene, the coupling portion is fed by a circular waveguide 2 (the tapered part providing matching), and the front face 4 of the lens portion 3 is specially contoured to control the distribution of radiation over an associated aerial reflector, to reduce side-lobes. A chamfer 5 is provided to minimize spill-over, and a circular disc or flange may be fitted over the waveguide behind the lens portion to reduce radiation caused by internal reflection at the face 4. Reduction of internal reflection may also be obtained by drilling quarter wavelength deep holes over the face 4. The dimensions shown in Fig. 1 relate to an assembly for use at a nominal frequency of 4 GHz. In another embodiment (Fig. 2, not shown) a quarter wavelength thickness of a suitable dielectric material is provided over the front face of the lens portion, to reduce internal reflection. In a third embodiment (Fig. 3, not shown) spill over is reduced by making the rear face of the lens portion of frusto-conical form, with an apex angle approximately equal to the angle subtended by the associated aerial reflector.

Title: Improvements in or relating to telegraph receivers
Inventor: KENYON PHILIP
IPC: H04L27/06
Filed: 1955-05-19
Abstract: 783,465. Code telegraphy. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. April 18, 1956 [May 19, 1955], No. 14434/55. Class 40 (3). In a carrier current signal receiver having a signal responding device operated by current flow through a thermionic tube to which a potential derived from the receiving signal is applied, first and second voltages derived by rectification of the incoming signal are applied in opposition to the valve to produce an effective negative bias which is maintained substantially constant by arranging that the circuit providing the voltage of greater value has the longer time constant. As shown in Fig. 3, the incoming signals are applied via a valve V3, a winding TR2(b) of transformer TR2 to a circuit comprising resistor R7, capacitor C1 and rectifiers MR1, MR2 connected to the grid of a valve V4 having in its anode circuit the operating winding of the receiving relay B. The first bias-control voltage, obtained by a circuit C4, R8 in combination with rectifiers MR3 and MR4, is applied via rectifier MR6 to the cathode of the valve V4. The second control voltage derived from the circuit C3, R6 and rectifier MR7 is applied from a tapping point of the resistor R6 to the control grid of the valve V4. The time constant of the circuit C4, R8 providing the voltage of greater value is arranged to be longer than that of C3, R6 and the differences between the values of the voltages is arranged to be one half of the maximum voltage as derived from the circuit C1, R7 in response to the incoming signals so that the effective negative control bias permits the transitions from mark to space and vice versa to occur at the correct instants. The valve V3 is provided with a negative feedback circuit by having its cathode connected via a circuit CB to the winding TR2(c) of the transformer TR2 which preferably has a step-down ratio. The relay B has a biasing winding in which the current flow is adjusted by a variable resistor R5 and the response time of the relay B is reduced by the negative feedback due to the resistors R2, R3 in the cathode circuit of the valve V4.

Abstract: 807,187. Steam turbines. SULZER FRERES S.A. May 8, 1957 [May 17, 1956], No. 14672/57. Class 110 (3). [Also in Group XVIII] In a steam turbineplant receiving steam at very high pressures, especially critical or super - critical pressures, and correspondingly high temperatures, a nitrogen - containing organic substance is added to the steam which has been expanded in at least one turbine stage to prevent corrosion of the blades of intermediate and lowpressure stage turbines which occurs as water drops separate from the steam and which is due to the presence of carbon dioxide. The preferred organic substance is an amine, especially diethylene oximide or cyclohexyl amine. In the plant shown in the Figure, steam from a generator 1 passes through first and second high-pressure turbine sections 2, 3, a reheater 4 and medium and low-pressure turbine sections 5, 6 to a condenser 7 whence condensate is returned to the hot well 10 through heaters 9 by a pump 8. Three storage and measuring vessels 12, 15, 18 for the amine are provided, with respective valved pipes 13, 17, 19 for feeding the amine into the steam flow entering the turbines 3, 5, 6. Alternatively a single tank with distributing pipes to the various steam lines may be provided.

Abstract: 438,431. Variable speed generator systems. C.A.V.-BOSCH, Ltd., WOOD, N. R., and WATERS, A. V., Warple Way, Acton, London. May 16, 1934, No. 14758. [Class 38 (iv)] In an automatic electromagnetic cut-out for use in battery charging systems having shunt and series windings which normally assist each other but oppose with reverse current from the battery to cause the opening of the cutout contacts, in order to render the cut-out more sensitive to reverse current, a resistance is automatically inserted in series with the shunt winding after the closure of the cut-out contacts, said resistance being controlled by separate contacts which are operated by the action of a separate electromagnet. As shown in the Figure the cut-out contacts a are closed by the shunt winding b connected across the dynamo d when the voltage of the latter exceeds a predetermined value, a series coil c having its circuit included with that of a battery e on closure of the cut-out contacts. After the operation of the cut-out when a further increase of dynamo voltage occurs a second electromagnet f causes the opening of contacts g normally short-circuiting a resistance h in the circuit of the shunt winding c of the cut-out. The introduction of this resistance reduces the energization of the cut-out and increases its sensitivity to reversals of current in the coil c. Thus at the commencement of any current reversal the cut-out immediately comes into operation to prevent any motoring of the dynamo such as might occur, particularly, in cases in which there is a freewheel device between the engine and transmission of a motor vehicle on which the cut-out is employed. In a modification the resistance is brought into circuit immediately a reversal of current occurs by the action of a polarized relay.
