Title: Automatic firearm
IPC: F41A19/00
Filed: 1935-11-14
Abstract: 465,805. Automatic guns. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST ,BRNO. Nov. 14, 1935, No. 31590. Convention date, Sept. 5. [Class 92 (ii)] An automatic gun of the recoiling-barrel type which is fired during the run-out of the barrel with locked breech, has the recoil absorbed by the forward momentum of the parts, and the breechblock and cartridge-feed mechanism operated by tapped gun gases acting on a piston or like motor. The Figure shows the parts in position for firing the first shot. On firing, the whole of the parts comprising the barrel 1, barrel-extension 8, gas cylinder 4, operating slide 11, and tilting breech block 9 move rearwardly until the gun gases pass through the vent 3 and act on the piston 12 of the slide 11. The member 17 of the slide then unlocks the breech block and opens the breech, thereby stressing the spring 14. The parts connected to the barrel meanwhile return under the action of a spring 15 and are arrested by a lateral spring catch 20 which rises into the path of a barrel shoulder 22 on being passed by a projection 23 on the slide 11. When the slide 11 returns, its projection 17 closes and locks the breech and its projection 23 releases the barrel. Further forward movement of the slide causes the projection 17 to strike the firing pin 18 before the barrel reaches its forward position. The piston 12 may fit loosely in the cylinder 4 to give a dash-pot damping action during the forward movement of the barrel after firing. Specification 465,112 is referred to.

Title: Method for the continuous measurement of the difference between the optical refractive indices of two liquids
IPC: G01N21/41
Filed: 1958-10-08
Abstract: 836,538. Refractometer. ZEISS-STIFTUNG, C., [trading as ZEISS, C. [Firm of]]. Oct. 8, 1958 [Oct. 12, 1957], No. 32097/58. Class 97(1) [Also in Group XL(b)] The arrangement of Specification 785,563 is modified to give a continuous measurement of the difference in refractive index of two moving liquids. In Fig. 1 the liquids 7, 8 flow past prisms 5, 6 and the two light boundaries due to critical angle reflection are focused alternately on the photocell 22 via the vibrating shutter 21. If the amounts of light are different the photocell gives an A.C. output which can be measured or (as shown) used to move an oblique absorbing block 27 in one light path to restore equality at the photocell. The refractive index difference is continuously recorded at 28. For rapid determination of values that are not too small, the absorbing block is omitted and balance obtained with an angularly adjustable mirror as in Specitication 785,563. The two mirrors 9, 10 are connected to slides of a potentiometer and the value obtained from the ratio of the resistances.

Title: Method and apparatus for Producing a Standard Radar Echo
IPC: G01S7/40
Filed: 1966-07-18
Abstract: 1,152,335. Radar. ELTRO G.m.b.H. & CO., GESELLSCHAFT FœR STRAHLUNGSTECHNIK. 18 July, 1966 [22 July, 1965], No. 32156/66. Heading H4D. Relates to bleeding off part of a pulse prior to transmission to produce a standard pulse in a pulse radar equipment, having, with respect to the transmitted pulse, a known delay (i.e. known simulated range), a known width, and a known amplitude. The last quantity allows the radar, when so standardized, to determine the cross-section of a target from the amplitude of its echo. The pulses for transmission at frequency f m  are fed along waveguide C1 to transmitting antenna A1. A portion thereof is decoupled off and fed to one input of mixer M1, having at its second input, the output of oscillator O at frequency f 1 . The resultant signal of frequency (f m -f 1 ) is compared in discriminator D1 with fZF 0 . Any difference causes oscillator O1 to alter its frequency until (f m  - f 1 )=fZF 0 . The pulse output of mixer M1 provides trigger pulses, which, after being delayed a predetermined amount in delay DC are fed to pulse generator PG1 to produce probe pulses of controlled width. An oscillator 02 operates at a frequency of f 2  and feeds its signal to a gate G1 which is opened by the probe pulses. The gated output is fed through a variable attenuator DM1 and fed portion is decoupled off and mixed in mixer M2 with the output of oscillator O1 at frequency f 1 . The resultant signal of frequency (f 2  - f 1 ) is fed to a discriminator D2 where the frequency is compared with fZF 0 . Any difference causes oscillator 02 to alter its frequency until (f 2  - f 1 ) = fZF 0 . Thus f 2  = f m . A predetermined portion E 2  of the pulse at f 2  is also decoupled and fed to one input of a switch S1. A predetermined portion E 1  of the pulse at frequency f m  is fed to the second input of the switch. By rapidly switching the switch, an amplitude comparison between E 1  and E 2  is made at AC1, which results in a variation of attenuator DM1 until E 1  = E 2 . Therefore the pulse delivered via CDM and waveguide C2, to the receiver RC1, has a standard known frequency, width, amplitude and timing.

Title: Pulse-type radar system
Inventor: COOK CHARLES E
IPC: G01C19/56
Filed: 1956-10-23
Abstract: 895,161. Pulse radar. SPERRY RAND CORPORATION. Oct. 23, 1956, No. 32343/56. Drawings to Specification. Class 40(7). In a pulse radar system the transmitted pulse is passed, before transmission, through a filter, having atime delay which increases inversely with. the frequency. Each frequency component of the pulse wave is subjected to a different delay thereby widening the pulse and reducing its amplitude. The converse action is produced at the receiver by a second filter so as to compress the pulse. Thus increased power may be supplied to the pulse, without reaching the peak power limitation and the detection range is increased. The overall action of the two filters produces a linear phase shift at carrier frequency and the system may be employed in M.T.I. systems.

Title: Improved process for the catalytic refining treatment of hydrocarbon distillates
IPC: C10G17/095
Filed: 1935-10-17
Abstract: Hydrocarbon distillates consisting of, or containing substantial amounts of constituents of motor fuel boiling range, particularly cracked gasolines, are refined by contact while hot with a solid catalyst comprising a mixture of a phosphoric acid and a finely-divided solid adsorbent which mixture has been calcined prior to the refining treatment.  Gases containing olefines are preferably added.  Olefines present are polymerized to high boiling materials which are removed in a final fractionation or, in the case of part of the normally gaseous olefines, to liquids of gasoline boiling range which increase the anti-knock value of the fuel.  The preferred catalysts are made by calcining ortho- or pyro-phosphoric acid and an adsorbent under controlled temperature conditions as described in Specifications 437,188, 463,272, [Group III], and 463,864, [Group III], and may be shaped and sized.  The refining may be effected, for example, at 93--210 DEG  C. and 5--20 atmos.  Steam or aqueous fluid may be added to prevent dehydration of the catalyst.  Specification 457,997, [Group III], also is referred to.ALSO:Hydrocarbon distillates consisting of, or containing substantial amounts of constituents of motor fuel boiling range, particularly cracked gasolines, are refined by contact while hot with a solid catalyst comprising a mixture of a phosphoric acid and a finely-divided solid adsorbent which mixture has been calcined prior to the refining treatment.

Title: Stapling machine
Inventor: SUTTON FRANCIS PAUL
IPC: A44B19/60
Filed: 1955-11-14
Abstract: 809,333. Stapling machines. LIGHTNING FASTENERS Ltd. Nov. 16, 1956 [Nov. 14, 1955], No. 32465/55. Class 89(3) The movement of the anvil into position adjacent the clenching punch in a power operated stapling maching closes a switch to actuate an electrically-operated single revolution clutch and drive the mechanism for stapling articles on the anvil, e.g. slide fasteners on trousers. A camshaft 1 carries operating cams 4, 5, a spur gear 9, a freely-mounted wheel 6 driven by an electric motor and a single revolution clutch 35 keyed to the shaft 1. The spur gear drives circular feed cams 14 through gearing 10, 12, 13, so that pronged staple elements in sheet form are fed forward one at a time along strip guides 17. Cam 4 operates a resilient punch 22 to bend the prongs of the staple through a right angle (Fig. 5, not shown). Cam 5 operates a roller 28 and starplate 29 driving shearing and clenching punch 26 in the lower part of which is the shearing knife 31 and spring lips 32. The anvil 36 is mounted on the support arm 37, pivoted at 39 and carrying a finger 44 adapted when the anvil has been moved to the stapling position to actuate a microswitch 46 and the solenoid which brings the clutch 36 into operation for a single cycle of stapling movements, i.e. feeding, bending, shearing and clenching of the staple. The support arm in its inoperative position presses the spring jaw 54 which normally holds the slider of a slide fastener adapted to be stapled to a garment, allowing the slider to be inserted or removed. In a machine for continuous feed and stapling operation (Fig. 11a, not shown), a locating pin on the anvil projects between the tapes carrying the interlocked slide fastener, and the end of each fastener portion moves the pin and anvil so as to actuate the switch and operate the stapler, the clenching action disengaging the locating pin for further control.
