Title: Improvements in or relating to crushing and/or grinding apparatus
IPC: B02C4/42
Filed: 1933-06-28
Abstract: 407,852. Grinding and crushing mills. TONKIN, S. R., P.O. Box 314, Salisbury, Southern Rhodesia, Africa. June 28, 1933, No. 18376. [Class 59.] In a grinding or crushing apparatus in which the material is pulverized between a stamp 1 and anvil 3, Fig. 1, the stamp is fixed on a rotary shaft 2 and is also given a vertical reciprocating movement owing to the centrifugal effect of an unbalanced mass 5 that is adjustably mounted on a disc 4 secured to the shaft 2. At one end the shaft 2 is supported, with a slight permissible degree of rocking movement, in a self-aligning bearing 8, and at the other end in a bearing 7 which is vertically slidable in guides 9. Thus, as the shaft is driven by the belt-wheel 11, the bearing 7 and consequently the stamp 1 rises and falls once during each revolution of the disc 4. According to a modification, Fig. 3, the unfixed end of the shaft 2 may be supported in a strap 20 at the end of an arm 21 oscillatable in a bracket 22. The material is fed to the anvil down an inclined chute, the rotation of the stamp assisting the feed and throwing the material clear on the opposite side of the anvil. In addition, the shaft 2 may have imparted to it an axial movement, for example, by the mechanism shown in Fig. 4, in which a collar 35 on the shaft is disposed between two apertured discs 30, 31, the latter of which is acted upon by a return spring 36<a> and the former of which is actuated from the wheel 11 through pin 43, rocking arm 42, pawl 40 carried thereby, ratchet wheel 39, link 37 and toggle 36.

Title: Improvements in and relating to Hydraulic Rotary Motors or Pumps
IPC: F04C2/10
Filed: 1968-04-22
Abstract: 1,177,733. Rotary hydraulic pumps and motors. RELIANCE ELECTRIC & ENG. CO. April 22, 1968 [May 4, 1967], No. 18837/68. Heading F1F. A rotary hydraulic pump or motor, comprises a housing 12, Fig. 3, having fluid passages (26, 28, Fig. 7, not shown), one an inlet and the other an outlet, a stationary internally-toothed outer gerotor element 34, Fig. 4, an externally-toothed inner gerotor element 40 keyed to an input or output shaft 30, an externally and internally-toothed intermediate gerotor element 50 disposed between the outer and inner elements and in operative engagement therewith for relative orbital movement and forming expanding chambers and contracting chambers therebetween, with the number of external teeth on the inner and intermediate elements being less than the number of internal teeth on the intermediate and outer elements respectively, as shown one less, and valve porting means continually connecting the expanding chambers between the outer and intermediate elements to one of said fluid passages and the contracting chambers between these elements to the other of said fluid passages. Operating as a pump with the shaft 30 rotating counter-clockwise, the inner element 40 imparts an orbital movement to the intermediate element 50 to thereby expanding chambers 60 and contract chambers 62. As element 50 orbits a cam surface 76, Fig. 3, thereon by engagement with a cam surface 78 on a ported plate 70 rotates the latter which is freely mounted on the shaft to maintain an arcuate slot 82, Fig. 5, in synchronous relationship with the expanding chambers and an arcuate slot 90 in synchronous relationship with the contracting chambers. The slot 82 communicates with the inlet passage (26) through radial ports 84, annular passage 86 surrounding the plate 70 and an annular channel 72 in the housing part 14. The slot 90 communicates with the outlet passage (28) through an annular groove 93 and an annular channel 74 in the housing part 14. A port 95 extending through the plate 20 substantially hydraulically balances this member. The number of external teeth on the intermediate element is twice the number of teeth on the inner element. The cavities between the elements 40 and 50 are maintained at the same pressure through an annular space 96 in the intermediate element 50. A modified rotatable ported plate 109, Fig. 10, (not shown) includes further arcuate slots connected to the slots 82, 90 by passages respectively so that the cavities between the intermediate and inner elements may be utilized for pumping or augmenting the motor torque.

Title: Collision avoidance system
IPC: G04G7/02
Filed: 1972-04-24
Abstract: 1355167 Automatic frequency control BENDIX CORP 24 April 1972 [19 May 1971] 18919/72 Heading H3A [Also in Division G3] In a collision avoidance system wherein a number of units, e.g. in aircraft, are allotted time slots in a repeating cycle, each unit includes a first local frequency source, e.g. a cesium beam standard, and a second local frequency source which is normally locked to the first source but takes over if the latter fails, the second source being then controlled in accordance with the average local clock error which is determined by comparing the arrival time of synchronization replies received by the unit, in response to synchronization requests, with corresponding predetermined points in the units time slots. The output from the first frequency source is normally available at terminal 10 and oscillator 20 is locked thereto by a phase locked loop circuit 14, whose output is also stored in a memory in a circuit 28. If the input 10 fails, control 34 connects output terminal 40 to the output of voltage controlled oscillator 20 via switch 36. The control 34 also changes switches 26 and 19 so that the memory in circuit 28 supplies its stored voltage to control the oscillator 20, and closes switch 30 to ensure that the memory is updated by error processor 45. The processor receives synchronization pulses by radio from a distant donor station in response to synchronization requests which are sent out at a predetermined point in each of the unit's time slots. The point of arrival of the response within the slot is used to indicate any lack of synchronism between the local unit and the donor (Figs. 2A, 2B, not shown). If the response arrives before or after the predetermined point, the number of clock pulses stored in a counter (86, Fig. 3, not shown) is correspondingly increased or decreased. The average local clock error is thus determined over a number of slot cycles and fed to a memory (56) to control the oscillator 20 via a D/A converter (58).

Title: Improvements in or relating to the recording of sound with the aid of light
IPC: G11B7/00
Filed: 1930-06-20
Abstract: 357,627. Optical sound - recording apparatus. GRAMOPHONE CO., Ltd., Hayes, Middlesex, and BROWNE, C. O., 3, Freeland Road, Ealing Common, London. June 20, 1930, No. 18932. [Class 40 (ii).] A sound-recording system comprising means for projecting a beam of light, modulated in accordance with the sounds to be recorded, through a recording gate 6 on to a moving light-sensitive film 7, is provided with means, including a monitoring gate 12 separate from the recording gate 6, for indicating when the amplitude of the recorded sound exceeds a predetermined value corresponding substantially to the maximum amplitude which can be recorded without distortion. As applied to the production of records of the varying width type, a prism 10 is so arranged as to reflect a portion of the recording beam on to the monitoring gate 12, and a photoelectric cell 13 in circuit with a loud-speaker is arranged behind this gate. The monitoring gate has the same length as the recording gate 6 so that overloading due to the amplitude of vibration of the vibrating image being so great as to cross the boundary of the recording gate occurs also at the monitoring gate and is indicated by distortion of the sound produced in the monitoring loudspeaker. The recording system comprises a ribbon 4 which is situated in a strong magnetic field and is connected in a circuit including a transformer 3, amplifier 2 and microphone 1. An image of a short length AB of the vibrating ribbon 4 is focused by an optical system 5 on to the recording gate 6. A second monitoring gate 11, co-operating with a prism 9 disposed in the path of the recording beam, is provided with a lens system 14 whereby an enlarged image of the gate may be viewed to facilitate correct centring of the edge of the ribbon 4. A lens system may be placed between the prism 10 and the monitoring gate 12. If desired, the monitoring gate 12 may be disposed so that it is outside the range of undistorted oscillations of the monitoring beam and allows light to reach the photo-electric cell only when overloading occurs at the recording gate 6. In a modification, the monitoring circuit is so adjusted that overloading occurs at some part of the circuit when the amplitude of the recorded sound exceeds the predetermined value specified above, and in this case the dimensions of the recording and monitoring gates may have no definite relationship. When this method is employed in making records of the variable density type overloading takes place when the changes of intensity of the recording beam are so great that the film emulsion will no longer respond in a normal manner, and the maximum amplitude which can be recorded without distortion is found by experiment.
