Title: Radio receiving antenna systems
IPC: H04H20/79
Filed: 1972-07-05
Abstract: 1376046 R.F. Couplings SIEMENS AG 5 July 1972 [13 Aug 1971] 31371/72 Heading H4A In a radio receiving aerial system relatively  weak signals from distant stations are received on directional aerials A, B at respective carrier frequencies f a , fb, and relatively strong signals from local stations are received on an omnidirectional (e.g., crossed-dipole) aerial C at respective carrier frequencies f c1 , f c2 , f c3 . Each received signal is processed in an individual channel level unit K1 to K5. These units each comprise input ports 2, 3 and output ports 4, 5 of a directional coupler, also a further port 1 which is directly coupled to the output. The signals from the aerials A, B are applied to the ports 1 of the units K1, K2, and the signal from the aerial C is applied to the port 2 of the unit K3. An output loop is formed by linking the ports 4, 5 of the adjacent channel level units K1 to K5, the port 5 of the unit K5 being earthed through a terminating resistor 7, and the port 4 of the unit K1 being coupled through an amplifier 8 to a feed line 9. The ports 2, 3 of the adjacent channel level units K3 to K5 are also looped, the port 3 of the unit K5 being earthed through a terminating resistor 6. In each of the units K1 to K5 the particular associated received signal, after selection by tuned resonant circuits and conversion to an intermediate frequency, is amplified, limited and subsequently converted back to its original or to another suitable frequency. Any signals of frequencies f a , f b  which are picked up by the omni-directional aerial C and which appear at the output 4 of the channel level unit K3 are so heavily attenuated as not to constitute a disturbance.

Title: Improvements in and relating to escapements
IPC: G04B15/00
Filed: 1931-11-13
Abstract: 386,745. Escapements. ENKLE, J., Landstuhl, Pfalz, Germany. Nov. 13, 1931, No. 31532. Convention date, Nov. 13, 1930. [Class 139.] In an escapement in which the balance spring is connected at its outer end to a rotatable pin wheel, the latter has a part rotation imparted thereto b the escape wheel, during each complete oscillation of the balance, whereby a progressive rotatior of the balance and pin wheel is ob tained. The pir wheel e having equally spaced pallet pins f<1> f<2> .. , f<1‹> is mounted coaxially with the balance wheel a and con nected to the balance spring i at g. The escape wheel p has arms k<1>, k<2>, k<3>, the ends of which have locking projections s, t, and tends to rotate clockwise, Fig. 1, under the stress of the driving spring acting on the pinion n. In operation, assuming the balance to be rotating in the direction of arrow x, the pin wheel e is locked by the pin f<3> abutting against projection t of arm k<1>. When the balance reverses the pin wheel commences to rotate clockwise, and the pin f<3> lifts to release arm k<1>. The 'scape wheel p now rotates clockwise and arm kl contacts with pin f<4> to rotate the pin wheel anticlockwise (against the action of the balance spring i) until the pin f<4> slips over the end of the arm and under the tension of the driving spring i locks against the projection t thereof, Fig. 4. When the balance again reverses to rotate anticlockwise, the pin wheel e eventually rotates similarly, pin f<4> releases the arm k<1> and the 'scape wheel rotates slightly until the pin f<2> locks in the projection t of arm k<2> thus completing one to and fro oscillation. The pin wheel thus progresses the angular distance between successive pins f<1>, f<2> .. , f<10> at each oscillation. In a modified arrangement, the balance pin i is connected to an eccentric stud on a wheel geared to the pin wheel.

Title: Improvements in or relating to doctor mechanism for the calender rolls of paper making machines
IPC: D21G3/02
Filed: 1927-11-24
Abstract: 290,188. Rice, Barton, & Fales, Inc., (Assignees of Lodding, F. W.). May 9, 1927, [Convention date]. Calendering and pressing.-In an arrangement of doctors for calenders used in paper-making electrical means are used for controlling the position of each doctor with respect to its roll. The doctors may be controlled in groups or all simultaneously, and the pressure of the doctors on the rolls may be regulated by controlling the strength of the electric current. The doctors 13, Fig. 2, are mounted on shafts 14 carried in brackets 23 on vertical coupling-rods 24. The shaft 14 carries a handle 15 and a loose arm 16 connected to the core 21 of a solenoid 22. A hook 17 controlled by a spring 19 engages a pin 18 on the handle 15. When the solenoid is energized the arm and handle are drawn down to lift the doctor into engagement with the roll. By releasing the hook 17 the handle may be turned to carry the doctor away from the roll. The currents from the mains 25, Fig. 6, is passed through circuits 26 through the solenoids 22 and rheostats 32, whereby the current can be regulated to control the pressure of the doctor on the roll. The circuits may be controlled by individual pushbuttons 31 or in batches by buttons 28, 29, or altogether by a button 27. The solenoid may be used to withdraw the doctor from the roll, the pressure to maintain it in its operative position being supplied by a spring.
